Clustering fastigiata peanut accessions for selection of early mature types suitable for the food market. Repositório Alice
RAMOS, J. P. C.; LUZ, L. N. da; CAVALCANTI, J. J. V.; LIMA, L. M. de; FREIRE, R. M. M.; MELO FILHO, P. de A.; SANTOS, R. C. dos.
Germplasm collections are the main raw material for breeding programs. Peanut is an important oilseed that serves to oil and food markets. The identification of early-mature genotypes and earliness adds benefits to crop production as it minimizes the costs of management and the losses of pod production due to occurrence of dry periods. In this paper, we estimate the genetic divergence in 77 peanut accessions (subsp. fastigiata), using three clustering methods, in order to identify early-mature genotypes and earliness for food market. The accessions were grown in field and phenotyped for 19 qualitative and quantitative traits. The Tocher methodology was employed for discriminating Valencia accessions. Both UPGMA and Principal Components Analysis (PCA) were...

Commercialization of Food Consumption in Rural China AgEcon
Gale, H. Frederick, Jr.; Tang, Ping; Bai, Xianhong; Xu, Huijun.
Rural households in China have traditionally consumed food mostly grown on their own farms. While they continue to rely on self-produced grains, vegetables, meats, and eggs for a large portion of their diet, rural households are now purchasing more of their food as they enter the mainstream of the Chinese economy. Cash purchases of food by rural Chinese households increased 7.4 percent per year from 1994 to 2003. Consumption has shifted from self-produced to purchased food at a rate faster than can be explained by income growth or changes in other household characteristics. The move away from self-produced food is associated with lower consumption of staple grains, the most important self produced food in rural Chinese diets. Food consumed away from home...

Comparing Consumer Attitudes towards Genetically Modified Food in Europe AgEcon
Springer, A.; Mattas, Konstadinos; Papastefanou, G.; Tsioumanis, Asterios.
As biotechnology evolves new methods of genetic engineering are now being applied to the production and processing of foods. This paper is trying to explore the attitudes of the European consumers towards genetic modification of food. Using survey data of the EU member countries the proposed research paper is planned to have a threefold output: 1) providing a comparative ranking of the EU member countries in relation to the prevalence of rejection of genetically modified food, 2) uncovering intra-european differences in genetic food engineering rejection as being based on socio-demographic and informational resp. knowledge based differentials between EU countries and 3) specifying the importance of socio-economic and informational determinants of a...

Comparing growth in surface and cave morphs of the species Astyanax mexicanus: insights from scales ArchiMer
Simon, Victor; Elleboode, Romain; Mahe, Kelig; Legendre, Laurent; Ornelas-garcia, Patricia; Espinasa, Luis; Retaux, Sylvie.
Background Life in the darkness of caves is accompanied, throughout phyla, by striking phenotypic changes including the loss or severe reduction in eyes and pigmentation. On the other hand, cave animals have undergone constructive changes, thought to be adaptive, to survive in this extreme environment. The present study addresses the question of the evolution of growth in caves, taking advantage of the comparison between the river-dwelling and the cave-dwelling morphs of the Mexican tetra, Astyanax mexicanus. Results A sclerochronology approach was undertaken to document the growth of the species in these two very distinct habitats. Scales from 158 wild Astyanax mexicanus specimens were analyzed from three caves (Pachón, Tinaja and Subterráneo) and two...

Comparison on animal production in organic and conventional systems MV&Z
Rossi, Gabriel Augusto Marques; Lemos, Paulo de Paula Lopes.
The market for organic products is increasing globally, seeking to fulfill the needs and expectations of consumers who believe it’s a healthier food. There are many controversies found in studies that assess primarily the physical-chemical, microbiological and the presence of this type of food of animal origin. This review aimed to evaluate the main differences between animal foods such as meat, milk, honey, eggs and fish produced in organic systems compared to those produced in conventional systems. The main differences are related to the physical-chemical food and no relevant differences were found between the possible presence of chemical or biological hazards in food of animal origin.

Comportamento alimentar e dieta de serpentes, gêneros Boiruna e Clelia (Serpentes, Colubridae) Iheringia, Sér. Zool.
Pinto,Carla da Costa; Lema,Thales de.
Boiruna maculata Boulenger, 1896 and Clelia rustica (Cope, 1878) were observed in captivity feeding snakes and rodents, respectively. Both species have shown a similar procedure in relation to the prey. Major behavior differences among the two species were: rodents killed before being swallowed, and snakes were mostly swallowed alive; both species are able to find the rodents head faster than the snake one; the coils formed during constriction were also used to hold the prey, specially the last coil, while swallowing rodents. Informations on stomach contents was gathered by dissection of preserved specimens of Clelia clelia (Daudin, 1803) and C. plumbea (Wied, 1820) were also included in the dietary study. The majority of preys consisted on snakes and...

Computer vision system approach in colour measurements of foods: Part II. validation of methodology with real foods Ciênc. Tecnol. Aliment.
TARLAK,Fatih; OZDEMİR,Murat; MELİKOGLU,Mehmet.
Abstract The colour of food is one of the most important factors affecting consumers’ purchasing decision. Although there are many colour spaces, the most widely used colour space in the food industry is L*a*b* colour space. Conventionally, the colour of foods is analysed with a colorimeter that measures small and non-representative areas of the food and the measurements usually vary depending on the point where the measurement is taken. This leads to the development of alternative colour analysis techniques. In this work, a simple and alternative method to measure the colour of foods known as “computer vision system” is presented and justified. With the aid of the computer vision system, foods that are homogenous and uniform in colour and shape could be...

Considering Macroeconomic Indicators in the Food versus Fuel Issues AgEcon
Qiu, Cheng; Colson, Gregory; Wetzstein, Michael E..
In this study, a Structural Vector Autoregression model (SVAR) is employed to decompose how supply/demand structural shocks affect food and fuel prices within fuel and corn markets. Results indicate that the relative importance of each structural shock in explaining the variation of corn prices is different. Our findings support the hypothesis that corn prices increase as a response to those positive demand shocks in the short run, while in the long run, global competitive agricultural commodities markets as well as positive supply shocks respond to commodity price shocks, restoring prices to its long-run trends. In conclusion, fundamental market forces of demand and supply as well as real economic aggregated demand shocks were the main contributors of the...

Consumer expectations towards origin-claimed food products. Compensation and acceptance for global trading system AgEcon
Giraud, Georges.
Origin- claimed food products mainstream gives diverse features over the world. The food labelling practices based on origin or provenance are frequently developed as a reaction to global trading system: private and NGO's initiatives (Fair Trade), enterprises in UK (Local Foods) and USA (Food Alliance), medals for winners in local exhibitions awards, or public regulation in European Union (PDO, PGI, Organic Farming). These practices claim at reaching consumer expectations. For a consumer who is frequently being uprooted and is stressed by his/her urban environment, the emotional content of where one's food is produced is greater than ever. With a longing for one's home, the consumer becomes an identity seeker. Origin, organic or fair trade food products...

Consumers' and Professionals' Responses to Situations Raising Ethical Questions AgEcon
Sirieix, Lucie; Gurviez, P.; Rohrig, C..
In this study we have attempted, in collaboration with an agrifood company, to compare and contrast the responses of consumers and professionals to the same set of situations raising ethical questions, in order to highlight the differences and the similarities of viewpoint between these two groups of stakeholders. In order to do this, we constructed multi-stakeholder scenarios comprising a description of the situation and the various possible approaches to managing the situation. We constructed two scenarios, dealing with the origin of the gelatin used in the company's products and the company's product information on livestock feed (GMO). This allowed us to: - study the extent of the professionals' ethical perceptions and the possible compromises between...

Co-operation and economic relationship as determinants for competitiveness in the food sector: the Spanish wheat to bread chain AgEcon
de Magistris, Tiziana; Gracia, Azucena.
The objective of the paper is to investigate the impact of co-operation amongst stakeholders of the food chain on enterprise competitiveness. The analysis focuses on the Spanish wheat to bread chain. A theoretical model is developed which covers the main components that define competitiveness (profitability, turnover, market share, customer loyalty and product quality), quality supply chain relationship (trust, commitment and satisfaction) and the main factors explaining supply chain relationship (i.e. quality and frequency of the communication, personal bounds, etc.). The Spanish wheat to bread supply chain has been chosen to empirically test the model. This sector is very fragmented all along the chain, with a high number of wheat farmers, millers and...

Croissance de jeunes palourdes (Venerupis semidecussata) en nurserie et en mer en fonction des conditions d'élevage ArchiMer
Lucas, Albert.
The japanese palourde Venerupis semidecussata was reared in the Bay of Brest, using hatchery reared spat. Experiments were performed with individuals of lenght 2 to 10 mm raised in a nursery, using raceways with slow running water enriched with unicellular algae, And also with individuals of lenght 8 to 20 mm raised at sea in suspended culture. It was observed that growth depends upon four groups of factors : (1) the functioning and equipment of the raceways, (2) the quantity and quality of the food, (3) the temperature and (4) various physico-chemical factors. When the equipment is satisfactory and when the physico-chemical fac­tors are normal for the species in question, the rate of growth depends essen­tially on the quantity of food, provided that the...

Culture alternative medium for the growth of extreme halophilic bacteria in fish products Ciênc. Tecnol. Aliment.
Yeannes,María Isabel; Ameztoy,Irene Mabel; Ramirez,Elida Elvia; Felix,Mónica María.
Halotolerant or halophilic (Archaeabacteria) microorganisms can be found in salted and ripening fish products that are not affected by salt. They can be moderate or extremely halophilic bacteria. The extremely halophilic bacteria require between 15-30% of NaCl for growth. The extremely halophilic archaeobacteria may be selectively isolated in different media. The aim of this work was to determine the effectiveness of the Salt-Agar-Milk medium, a medium modified in our laboratory through the addition of MgSO4 and KCl - named SAMm, and its effect on the bacterial growth by means of comparison with other media, with and without milk, determining time of incubation and counting. Two samples of salted fish from local fish salting factories and two laboratory...

DEMAND FOR FOOD QUANTITY AND QUALITY IN CHINA AgEcon
Gale, H. Frederick, Jr.; Huang, Kuo S..
As their incomes rise, Chinese consumers are changing their diets and demanding greater quality, convenience, and safety in food. Food expenditures grow faster than quantities purchased as income rises, suggesting that consumers with higher incomes purchase more expensive foods. The top-earning Chinese households appear to have reached a point where the income elasticity of demand for quantity of most foods is near zero. China’s food market is becoming segmented. The demand for quality by high-income households has fueled recent growth in modern food retail and sales of premium-priced food and beverage products. Food expenditures and incomes have grown much more slowly for rural and low-income urban households.
