A DISCRETE STOCHASTIC MODEL TO DETERMINE FOOD QUALITY BY USING SIMULATION: A STRAWBERRY CASE STUDY
Provedor de dados: 70
Autores: González-Hernández,Isidro J.; Granillo-Macías,Rafael; Rondero-Guerrero,Carlos; Martínez-Flores,José L.
ABSTRACT The agri-food supply chain (AFSC) sets a series of challenges in the production, storage, distribution, and transportation processes, as the market's requirements for fresh food combine food quality and safety attributes. This research suggests a discrete event modeling to study the behavior of food quality in all supply chains (SCs) in terms of temperature and time variables in a stochastic manner. The ProModel software was used to simulate strawberry quality in the SC, considering a distribution route to export the fruit from Mexico to the United States. The suggested model together with a computer simulation analyzes the fruit quality from two perspectives: with and without a cold chain (CC). The obtained results revealed that in the case of CC...

Alimentation expérimentale de l'huître Crassostrea gigas à l'aide de navicules bleus Haslea ostrearia (Simonsen) de différentes tailles
Provedor de dados: 5
Autores: Barille, Laurent; Bougrier, Serge; Geairon, Philippe; Robert, Jean-michel.
The influence on the feeding physiology (clearance, filtration, ingestion, absorption) of the Japanese oyster Crassostrea gigas of low concentrations of suspended particulate matter (SPM ranging from 2 to 20 mg.l-l) and high food quality (mean organic fraction =54 %) was studied in the laboratory. Experimental diets were made up with three strains of the "blue diatom" Haslea ostrearia, which is responsible of the greening of oyster-ponds. The strains were characterized by different sizes (48, 65 and 98 µm respectively) but possessed the same density and biochemical composition. Clearance rate was found constant at 2.2 1.h(-l).g-l dry weight and therefore was not influenced by increasing seston load. Pseudofaeces production was observed for SPM...

Abstract: The objective of this work was to evaluate the effects of the split and combinated application of foliar zinc (ZnF) + soil Zn (ZnS) on Zn concentration in the grains (ZnCG) of common bean (Phaseolus vulgaris). Two experiments were carried out in a greenhouse during two seasons. In the first experiment, two common bean cultivars received six ZnF rates (0, 120, 240, 480, 720, or 1,200 g ha-1), with split applications at the R5, R7, and R8, or R7 and R8, or R8 plant stages. In the second experiment, one cultivar received three ZnS rates (0, 5, or 10 kg ha-1) combined with ZnF rates (0, 1, 1.5, 3, 6, or 10 kg ha-1). In the first experiment, with the ZnF increment, ZnCG increased linearly from 15.3 to 20.7 mg kg-1. ZnF splitting did not affect ZnCG....

The Food Retail Revolution in Poor Countries: Is It Coming or Is It Over?: Evidence From Madagascar
Provedor de dados: 31
Autores: Minten,   Bart.
Global retail chains are becoming increasingly dominant in the global food trade and their rise leads to dramatic impacts on agricultural supply chains and on small producers. However, the prospects and impacts of a food retail revolution in poor countries are not yet well understood. Here, we examine this question in Madagascar, a poor but stable country where global retailers have been present for over a decade. Our survey and analysis finds that while global retail chains sell better quality food, their prices are 40 to 90% higher, ceteris paribus, than those seen in traditional retail markets. In poor settings, characterized by high food price elasticities, a lack of willingness to pay for quality, and small retail margins, supermarkets appear to set...

Food Quality Standards in Equilibrium Models: A Discussion of Current Modeling Approaches
Provedor de dados: 31
Autores: Nolte,   Stephan; Rau,   Marie-Luise.
Throughout recent year food quality standards have become a ubiquitous phenomenon that nationally and globally influences agri-food markets. With equilibrium models commonly used in the quantitative analysis of market and trade effects, we review possible approaches to modeling standards existent in the literature, elaborate the reasoning behind them and discuss their suitability to reflect "real world" situations. While the modeling approaches identified may respectively depict a specific situation, they may not be appropriate in others. That is they capture certain effects of standards only. With increasing ability to account for the various effects of standards, the modeling approaches become more complex and the data requirements increase.

Fragmenting markets and quality change in New Zealand foods: empirical analysis with a Rotterdam model
Provedor de dados: 31
Autores: Khaled,   Mohammed; McWha,   Vhari; Lattimore,   Ralph G.
Very little is known about changes in the demand characteristics of food in New Zealand. As far as we can determine, there has never been a complete disaggregated food demand model estimated for New Zealand. The object of this paper is to update these estimates using more recent data to see whether there are grounds for believing that the structural changes that occurred primarily during the last two decades are having effects on the magnitude of food demand elasticities in New Zealand. To this end, a Rotterdam food demand system is estimated using time series data. The results indicate that over the last 20 years, household consumption has increased for fruit and vegetables, poultry, food eaten away from home, and sweet products, drinks and other foods....

Selling Australia as ‘clean and green’
Provedor de dados: 31
Autores: Chang,   Hui-Shung (Christie); Kristiansen,   Paul.
‘Clean and green’ has been used as a marketing tool by Australian governments to promote agricultural products overseas. But how valid are these claims? Is the ‘clean and green’ image campaign effective? And should government be involved? We conclude that Australia may have had a ‘clean and green’ image in some markets, but in the future, concrete proof of environmental and quality credentials will be required to satisfy increasingly better-informed and more demanding customers. We argue that governments cannot, and should not, continue to promote Australian products based on an undefined ‘clean and green’ image. Rather, more resources should be directed to the development, promotion and wide adoption of integrated, credible and well-defined environmental...

On food quality in domestic markets of developing economies
Provedor de dados: 31
Autores: Vandeplas,   Anneleen; Minten,   Bart; Swinnen,   Johan F.M.
Food quality has become an important determinant of success in global food trade and growers for international markets have to continuously adjust to buyers’ requirements. It is however not clear to what extent there is a demand for food quality - and how much buyers are willing to pay for it - in the domestic food markets of developing economies. Based on unique price and trader data from domestic food markets in a poor country in Africa (Madagascar) and an emerging economy in Asia (India), we compare quality and quality’s pricing. We find significantly better quality and higher quality premia (using revealed as well as stated preference methods) in the richer country, probably leading to an impetus for the development of modern market channels in this...

Institutional Change and Acceptance of Quality Assurance: The Case of Organic Farming in Germany
Provedor de dados: 31
Autores: Schulze,   Holger; Jahn,   Gabriele; Spiller,   Achim.
The institutional framework of the certification scheme is a crucial factor for the future success of the organic market. Increasing complexity and a few scandals indicate that the current control structures might be insufficient. A better understanding of farmers’ attitudes is necessary to increase acceptance and to guarantee the longer-term success of the organic certification system. Against this background we designed a theoretical framework based on a cognitive perspective. The empirical basis of the study was a survey conducted with organic farmers in Germany. Results highlight that the majority of the farmers accept the present organic certification system, but are not convinced of its cost-benefit relationship.

Autores: Misso,   Rosa.
The environmental emergencies, the alimentary crisis, the increase of chronic illnesses, pushes the consumers to seek informative channels often also "virtual" as a reassurance for their own health, for the salubriousness of food and above all as a direct channel with the enterprises. For these last, then, it becomes fundamental to look at the information, to the virtual nets, and to the Information and Communication Technologies (ICTs) especially as powerful means of communication. Therefore, the work analyzes the role that the ICTs develop in the productive sector of ‘Mozzarella di Bufala Campana’, a particularly important product for the economy of the Region but in crisis because installed in a context of environmental emergencies that have seriously...

Spread of retailer food quality standards: An international perspective
Provedor de dados: 31
Autores: Herzfeld,   Thomas; Drescher,   Larissa S.; Grebitus,   Carola.
Privately initiated food quality standards are currently important elements in the marketing of food and agricultural products. At the same time, they stand in the centre of a discussion about potential negative effects on small farmers and farmers in developing countries. This study aims at analysing the adoption of two private food standards, BRC Technical Food Standard and GlobalGAP, at an aggregated cross-country level. The results of the econometric analysis reveal some (potential) barriers for developing countries to access this type of organisational innovation. Certificates seem to be issued more probably in larger and wealthier countries, countries with a better institutional quality, better infrastructural conditions and in former UK colonies.

Autores: Borgen,   Svein Ole.
The paper addresses recent changes in the Norwegian agrifood industry from the analytical perspective of quality conventions. Storper and Salais’ “worlds of production” plus Boltanski and Thévenots’ “orders of worth” are used as a basis for the empirical study. First, the paper discusses how the largest Norwegian branders try to strategically adapt to “novel” quality attributes like health-enhancing food, origin/terroir, environmental sustainability and ethics. Second, the paper investigates the companies’ quality signalling strategy: How are these “novel” qualities communicated to consumers? Multiple options are available: Do they attempt to systematically incorporate “novel qualities” into their private brand equity (“conventionalizing qualities”)? Do...

Autores: Banterle,   Alessandro; Peri,   Massimo.
The paper considers six EU Nuts II regions (Lombardy and Tuscany for Italy, Rhone-Alpes and Paca for France, Catalunya and Murcia for Spain) and studies the processing sector of organic products, investigating its links with agriculture and the retailing sector. The choice of these regions is due to the fact that the analysis is linked to a European project concerning cohesion among Mediterranean countries. The purpose is to analyze the processing sector of organic products in terms of firm capabilities to perform a quality management strategy and to analyze the vertical coordination in the organic supply chains. The survey was carried out on a sample of 304 firms stratified on the basis of the six regions involved in the study. Results showed the...

Autores: Naspetti,   Simona; Zanoli,   Raffaele.
Many more consumer s have tried at least once organic food, but despite higher consumer awareness, they still show a great concern about food quality and safety. Recent research showed that there is still little knowledge of how organic products are produced and processed and which characteristics are fundamental for the consumer with regard to quality and safety. In this scenario, primary producers, processors and other stakeholders in the organic supply- chain have the difficult task of understanding consumers' complex and sometimes contradictory wishes with regard to organic food. The aim of this study is to examine food quality and safety issues related to buying organic products. To provide better insight on the safety and quality issues in a cross -...

Consumers' Demand for Pork Quality: Applying Semantic Network Analysis
Provedor de dados: 31
Autores: Grebitus,   Carola; Bruhn,   Maike.
Consideration of consumers' demand for food quality entails several aspects. Quality itself is a complex and dynamic concept, and constantly evolving technical progress may cause changes in consumers' judgment of quality. To improve our understanding of the factors influencing the demand for quality, food quality must be defined and measured from the consumer's perspective (Cardello, 1995). The present analysis addresses the issue of food quality, focusing on pork-the food that respondents were concerned about. To gain insight into consumers' demand, we analyzed their perception and evaluation and focused on their cognitive structures concerning pork quality. In order to more fully account for consumers' concerns about the origin of pork, in 2004 we...

European Food Quality Policy: The Importance of Geographical Indications, Organic Certification and Food Quality Assurance Schemes in European Countries
Provedor de dados: 31
Autores: Becker,   Tilman C.
In the early 1990s reform of the EU’s Common Agricultural Policy led to a change in emphasis away from price into policies to promote rural development, in part through improvements to food quality. Geographic indicators are only one of a range of EU policies designed to foster these goals. Geographic indicators are put within the context of the wider quality enhancement policies that include quality assurance schemes and organic production. There appears to be considerable regional differences within the EU when it comes to the use of the various quality-enhancing policies available. The member states of the EU can be grouped into four different clusters, each characterized by a different quality policy strategy.

Using original data collected about growers, traders, processors, markets, and village communities, we compare the situation in four states – Tamil Nadu, Uttar Pradesh, Maharashtra, and Orissa. We examine the way that information about crop attributes is conveyed (or not) along the value chain. We also document the infrastructure available at the level of the market. We find that little information circulates about unobservable crop characteristics. Growers receive a price premium when they dry, grade, and pack their produce, but we find no evidence that information about crop health and safety or agricultural practices circulates through the value chain or that growers are encouraged to follow specific agricultural practices for quality purposes.

In Benin, traditional parboiling is still widely practiced among rice processors, resulting in inferior grain quality. A new parboiler was introduced to improve the milling yield and quality of local rice. We conducted Vickrey second price auctions followed by a consensus session to elicit rural Beninese consumers’ willingness to pay for rice obtained through the new parboiler and two locally innovated parboilers. Relative to traditionally parboiled rice, consumers were willing to pay price premiums of 9–13% for rice obtained through a local parboiler using a container of which the bottom is a perforated metal, 27% for rice obtained through a local parboiler using wooden sticks at the bottom of the pot, and 25–34% for rice parboiled through the improved...

Food systems in developing countries are undergoing a profound transformation characterized by the emergence and expansion of modern retailers and integrated supply chains. Appropriate policies are needed to guide this transformation, presupposing a good understanding of consumer preferences. We analyze consumers’ valuation of different vegetable attributes in metropolitan areas of Vietnam, using contingent valuation techniques and a mediation framework for two specific examples. Consumers are willing to pay an average price premium of 60% for Chinese mustard that is free of chemical residues and of 19% for different convenience attributes of potatoes. Income levels and media have positive impacts on the willingness to pay, partly mediated through...

The notable growth experienced by organic agriculture in Spain, has not been accompanied by a similar development in the consumption of organic foods, with most of the organic agricultural output being exported. This study focuses in analyzing Spanish consumer's attitude versus organic foods, in order to identify the factors that influence the demand. For this purpose, 130 surveys are conducted among consumers in a medium-sized city in Spain and processed using different statistical analysis, determining the level of knowledge about these products, consumer's shopping habits, and criteria, which support or dissuade the consumption of these products.

Quality Warranties and Food Products in Argentina. What Do Consumers Believe In?
Provedor de dados: 31
Autores: Berges,   Miriam E.; Casellas,   Karina S.
Consumers increasingly demand multiple-quality attributes in food products and value reliable means to identify them. For producers, the effective communication of their products quality is a marketing strategy. Therefore, another market of information associated with the new food markets emerges. This market is closely linked to the institutional environment and the level of trust in different information sources. In this article the emphasis will be put on how the different quality signals provided by the firms in their products affect the consumers´ behaviour. The objective is to investigate domestic consumers' perceptions and beliefs about food quality information in Argentina to identify the mechanisms that fully guarantee this quality. The results...

The paper addresses "food safety" and 'food quality' from the position of commodity and food science rather than economy. The various descriptions of both terms in literature are reviewed in connection with customer/supplier ability to evaluate food safety and quality by examination of various characteristics. Food safety has been described as opposite to food risk. Differences in perception of food risk by customer, producer/supplier and official agencies are discussed in this paper. The objective safety (and quality) of food can be evaluated using three categories of food risk (biological, chemical and physical) measured on a seven step intensity scale by producers and official agencies but not by customers. This leads to formulating food safety policy...

The relationship between product quality (as indicated by unit value) and export performance, both measured in absolute (per capita) and relative terms, is investigated.  Five EU countries (DE, UK, FR, ES, IT), three product categories (cheese, meat preparations and wine), three export destinations (intra EU, extra EU and world) and two time periods (1995-1999 and 2000-201) are analysed.  The estimation results show that the connection between quality and export performance is positive for Italy, Spain and France but depends on the product category (but not on the period), and differs (but not in all cases) according to the export destination.  While the signs of the estimated slope coefficients are stable, the obtained statistical significance levels for...

Consumers’ quality judgement depends on their knowledge concerning certain quality attributes. Against this background this paper presents the results of a consumer survey conducted in 2004. We focus on measuring consumers’ cognitive structures regarding pork and potatoes. On this account we apply a free-association technique and a variation of concept mapping. Our analysis shows that consumers’ cognitive structures are quite complex and heterogeneous. Product characteristics such as ‘taste’ and ‘fat content’ dominate consumers’ knowledge. To predict the eating quality of pork consumers prefer intrinsic quality cues. In contrast to that extrinsic quality cues are used to predict the origin of the given product. With regard to potatoes the intrinsic quality...

Autores: Reed,   Albert J.; Elitzak,   Howard; Wohlgenant,   Michael K.
This bulletin provides an alternative approach for computing retail-farm price margins. Current published estimates of retail-farm price margins are calculated assuming that food markets are comprised of identical firms producing, in fixed-factor proportions, a homogeneous set of final food products. The approach presented here relaxes these assumptions by relying on an expenditure-based measure, justified by the Generalized Composite Commodity Theorem, that reflects consumer demand for the many different elementary food products associated with a modern food market. This measure allows a direct link between consumer demand for diverse elementary products and food quality and marketing services where increases in retail-farm price margins, for example, can...

An Incentive System for Salmonella Control in the Pork Supply Chain
Provedor de dados: 31
Autores: Backus,   Ge B.C.; King,   Robert P.
This paper presents a dynamic principal-agent analysis of an incentive system for Salmonella control in the pork supply chain. The incentive system determines quality premiums to the producer, testing frequencies for hogs delivered, as well as charges to the producer for testing and penalties. Using cost estimates and technical parameters, we evaluate the cost effectiveness of plant and farm control measures and trade-offs between prevalence reduction and related costs and gains. We also assess the impact of ownership structure on incentive system parameters and performance for a wide range of prevalence threshold levels. Differences in control actions, bacteriological prevalence and the overall welfare gain for the chain are very small across ownership...

Consumer Demand for Quality: Major Determinant for Agricultural and Food Trade in the Future?
Provedor de dados: 31
Autores: Caswell,   Julie A.; Joseph,   Siny.
The impact of consumer demand for quality on the agricultural and food system is an increased emphasis on quality differentiation but not all in the direction of upgrading quality. The more elite market segments are thriving and reaching growing numbers of consumers but the basic price/quality markets remain strong. Most recent economic studies find that consumers are willing to pay for food safety and other quality attributes, and for information about them. The magnitude of the valuations varies by food product, attribute, country, and study design. This literature and a case study of genetically modified foods suggest that consumer demand has a strong effect on agricultural and food trade.

Improving Food Quality through Institutional Innovations: Using a Free‐Rider Approach for Collective Action
Provedor de dados: 31
Autores: Nuppenau,   Ernst-August.
This paper outlines how a team work approach, recently suggested in institutional economics to overcome the problem of externalities, can be used to promote better food quality. Cost sharing as “team work” is considered a novel institution to improve food quality by giving incentives to overcome the public good character of quality. We translate the approach from negative to positive externalities. Hereby: (1) We make a reference to the current state of the discussion on how food quality depends on efforts of a food industry to get a better image and discuss how much need there is to improve quality. (2) An outline of a mathematical approach of a “team work” is presented in the provision of quality as a positive externality and (3) the approach is adapted...

The objective of the present study was to characterize the food sources, as well as the composition and quality of milk obtained from household farms of western Paraná State (Brazil) with and without technical assistance during the different seasons. For such, 24 properties were selected, 12 of which only received assistance and technical support. Four milk samples were taken (summer, autumn, winter and spring) to assess the physicochemical composition, somatic cell count and total bacterial count and feed supplied to the animals to assess the chemical composition (crude protein, ash, dry matter and neutral detergent fiber). The data were analyzed in a completely randomized design with a 2 × 4 factorial arrangement; the first factor was the presence and...

Diet-induced developmental plasticity in life histories and energy metabolism in a beetle
Provedor de dados: 97
Autores: URREJOLA,SERGIO; NESPOLO,ROBERTO; LARDIES,MARCO A.
Adaptive phenotypic plasticity, has been recognized as an important strategy by which organisms maximize fitness in variable environments, which vary through development. A disassociation among stages should represent a null effect of the environment experienced during early ontogeny in the expression of adult traits. Food quality greatly influences survival, development and reproduction in many arthropod herbivores. We examined the effects of diet protein in physiological and life-history traits in the yellow mealworm beetle Tenebrio molitor through ontogeny. We established four experimental treatments: Low Protein (LP), Low Protein Control (LPC), High Protein (HP), and High Protein Control (HPC) with recently eclosioned larvae each. Individuals were...

Importance of diet in the growth, survivorship and reproduction of the no-tillage pest Armadillidium vulgare (Crustacea: Isopoda)
Provedor de dados: 97
Autores: FABERI,ARIEL J; LÓPEZ,ALICIA N; CLEMENTE,NATALIA L; MANETTI,PABLO L.
The studies of Armadillidium vulgare as pest are virtually null worldwide. However under no-tillage systems this species has found an adequate environment for its development and it has become an important pest in some crops in Argentina. It has been shown that the composition of vegetables affects the isopods biology. Our hypothesis was that soybean leaf litter has high nutritive value which allows A. vulgare to grow faster, survive longer, and have higher fecundity favoring the population increase and turning it into a crop pest. Growth and survivorship of juveniles and adults, egg incubation period, offspring number per female and offspring mean body weight were determined in individuals fed with leaf litter of soybean, sunflower, wheat and pasture. The...

ผลของสาร CPPU ต่อคุณภาพหลังการเก็บเกี่ยวผลมะละกอพันธุ์แขกดำ
Provedor de dados: 106
Autores: Somkuan Boonsoda; Sureeporn Bunsiri; Suriyan Supapvanich; Surassawadee Promyou.
The objective of this study was to determine the effect of CPPU on postharvest quality of ‘Kaek Dum’ papaya fruit. Fruits at the half-ripe stage were selected to test a dipped treatment with 0, 2 and 4 mg/l CPPU for 60 min. Then, all the samples were stored at 12°C (80-85% RH) for 15 days. The results showed that the fruit dipped in 4 mg/L CPPU had lowest firmness and the peel and pulp color development occurred rapidly than those in the other treatments. No differences in weight loss and membrane degradation when indicated by electrolyte leakage were found between treatments. The results indicated that such a CPPU treatment in papaya fruit may be accelerated fruit ripening.

Autores: Kulvadee Trongpanich; Siriporn Stonsaovapak; Winus Puminat; Montatip Yunchalad.
Five varieties of Thai commercial dried and semi-dried pickled fruits and vegetables were sampled from Thai local markets and determined for qualities in chemical and microbiological aspects. Each product variety was sampled from five production plants. The sampling was done in triplication, thus made the total of 75 samples. The products were salted shredded green mango, salted shredded green papaya, sweeten shredded radish pickle, salted whole radish pickle, and whole peach pickle. The samples were analyzed for pH, acidity (as lactic acid), aw, moisture, benzoic acid, sorbic acid, saccharin, NaCl, and SO2. It was found that every sample was an acid food, from which its pH not more than 4.6, except one sample from one brand of salted radish pickle had pH...

ABSTRACT The study developed a sensory scheme based on the Quality Index (QI) and estimated the shelf-life for whole tambaqui, Colossoma macropomum (Cuvier, 1818), stored in ice, assessing and determining the most appropriate chemical, physical, bacteriological and quality sensory parameters and their changes during storage time. Ninety six fish were evaluated at 1, 3, 5, 8, 10, 12, 15, 17, 19 and 22 days of ice-storage. The developed quality index (QI) showed four main quality attributes with a total of 29 demerit scores. The skin mucus and odor, as well as general appearance and ventral elasticity had a great importance for the statistical model applied, while eyes, gill mucus and dorsal elasticity showed lower significance for tambaqui QI. The pH showed...

VIS/NIR spectral signature for the Identification of Peanut Contamination of Powder Foods
Provedor de dados: 111
Autores: Ghosh, Satyabrata; Domínguez, Teresa R. Cuadrado; Diezma, Belén; Lleó, Lourdes; Barreiro, Pilar; Lacarra, Teresa García; Roger, Jean-Michel.
Visible-Near Infrared reflectance spectra are proposed for the characterization IRMM 481 peanuts in comparison to powder food materials: wheat flour, milk and cocoa. Multidimensional analysis of spectra of powder samples shows a specific NIR band centred at 1200 nm that identifies peanut compared to the rest of food ingredients, regardless compaction level and temperature. Spectral range 400-1000 nm is not robust for identification of blanched peanut. The visible range has shown to be reliable for the identification of pre-treatment and processing of unknown commercial peanut samples. A spectral index is proposed based on the combination of three wavelengths around 1200 nm that is 100% robust against pre-treatment (raw or blanched) and roasting (various...

Uptake and translocation of Cd and Zn in two lettuce cultivars
Provedor de dados: 42
Autores: FONTES,RENILDES L.F.; PEREIRA,JULIANA M.N.; NEVES,JULIO C.L.
Excess of heavy metals in agricultural soils is a matter of concern since it may decrease economic yield as a result of toxicity and lower product quality as a result of metal accumulation in edible plant parts. Among plant species and among cultivars within species a natural variation in uptake, translocation and distribution of trace elements occur. The transference of Cd and Zn, from soil to two lettuce (Lactuca sativa L.) cultivars grown in greenhouse, was evaluated in separate experiments for Cd and Zn.Plant dry and fresh matter yield and plant Cd and Zn concentrations were determined. Cultivar CRV showed greater potential for yield than CMM in both experiments. Cadmium and Zn translocation from roots to shoots increased with the increase of soil Cd...
