| A 2006–2009 közötti időszakban a tej fogyasztói ára Magyarországon volt a legmagasabb. A fogyasztói árak közötti árkülönbségek mögött számos tényező húzódik meg: az áfatartalom, a kereskedelmi láncok árpolitikája, a feldolgozói ár és végül a termelőknek fizetett felvásárlási ár. Az áfa mértéke alapvetően makrogazdasági adottság, egy adott ország gazdaságpolitikájának függvénye. Az EU régi tagállamaiban a kiskereskedelmi láncokkal kialakult kapcsolatrendszer és a piaci kultúra évtizedes fejlődés eredménye. Ezzel szemben a kelet-európai élelmiszerpiac szereplőire valósággal rászakadt az új típusú, tőke intenzív kiskereskedelem, ami a korábban megszokotthoz képest alárendelt helyzetbe hozta az értékesítési láncban a beszállítókat, a termelőket.

| The use of lactic acid bacteria (LAB) as bioprotective cultures can be an alternative to chemical preservatives or antibiotic to prevent fungal spoilage in dairy products. Among antifungal LAB, Lactobacillus harbinensis K.V9.3.1Np showed a remarkable antifungal activity for the bioprotection of fermented milk without modifying their organoleptic properties (Delavenne et al., 2015). The aim of the present study was to elucidate the action mechanism of this bioprotective strain against the spoilage yeast Yarrowia lipolytica. To do so, yeast viability, membrane potential, intracellular pH (pHi) and reactive oxygen species (ROS) production were assessed using flow cytometry analyses after 3, 6 and 10 days incubation in cell-free supernatants. The tested... |

| ABSTRACT The development of different products that confer health benefits on the population is a challenge for those who work with food. The aim of this study was to elaborate two formulations of kefir cheese (C1 and C2) and whey (W1, W2), and to evaluate their in situ antibacterial activity against microorganisms of interest in food. Pasteurized milk, powdered milk and kefir grains were used in preparing the products and their percentage composition was determined. C1, C2, W1 and W2 were contaminated with five different logarithmic fractions (A = 8log to E = 4log CFU/ml) of Staphylococcus aureus (ATCC 25923) and Escherichia coli (ATCC 11229), with antibacterial activity assessed over 0, 24, 48 and 72 hours of exposure. The results demonstrated the... |

| This report documents data and other information gathered from a survey of urban households in Beijing, Shanghai, and Guangzhou, China. The survey was conducted as part of a research project aimed at understanding the evolution of dairy markets in Asia and the implications for dairy product trade. The survey data provide insights into the purchasing behavior and attitudes of urban consumers in China with respect to dairy products. The report describes the survey and collection process, summarizes selected data from the survey, and provides anecdotal information about the development of dairy production, processing, and product marketing in China. |

| Abstract Real-time PCR (qPCR) has been used for rapid identification of Salmonella Typhimurium and Staphylococcus aureus in dairy foods, but is unable to differentiate viable and unviable pathogens. Ethidium bromide monoazide (EMA), a DNA-intercalating agent, can detect only viable cells because selectively enter cells considered unviable and bind to their DNA, inhibiting its amplification during qPCR. The objective was to establish a protocol for detection of viable Salmonella Typhimurium and S. aureus, experimentally inoculated in coalho cheese, by the use of EMA combined with qPCR. The protocol was effective for the identification of viable Salmonella Typhimurium in coalho cheese but not for the S. aureus cells. Concentrations of viable Salmonella... |

| The advancement of investor-owned firms (IOF), mainly multinational ones, and the reduced participation of cooperatives in dairy production and processing in Brazil along the past few decades has been calling the attention of researchers. With the participation of 59 productive units, distributed over 9 states of the Brazilian territory, the objective of this work was to analyze the efficiency of the cooperatives in the dairy industry using the Data Envelopment Analysis (DEA). The results show that, in general, the cooperatives presented better performance in terms of scale rather than in terms of productive efficiency. This stimulates sectorial politicies that promote improvements in the use of the resources to obtain greater efficiency in milk processing. |

| This study was conducted to determine the prevalence rate, enterotoxigenecity, and antimicrobial resistance of S. aureus isolated from dairy products in Iran. From September 2010 to July 2011, a total of 347 samples from various dairy products, traditional and commercial, were collected from randomly selected retail stores. Overall, 20 samples (5.8%) were found to be contaminated with S. aureus. The highest prevalence of S. aureus was found in traditional cheese (11.1%), followed by traditional ice-cream (5.9%), cream (5.6%), and butter (5.3%). The ability to synthesize classical staphylococcal enterotoxins (SEA-E) was determined in 7 of 20 (35%) isolates by using ELISA. SE type C was the most common enterotoxin found in the isolated S. aureus (42.9%),... |

| ABSTRACT Cheeses are dairy products prepared from coagulated milk, and which, under Brazilian legislation, can be classified according to their fat and moisture content. Cheeses such as Minas Frescal and Ricotta have a high moisture content and are highly perishable. As such, chemical changes can occur and interfere with the shelf life of these products. In order to evaluate the physical and chemical parameters of Minas Frescal and Ricotta cheeses marketed in Fortaleza, Ceará, 10 samples of the products were evaluated. The variables of weight, temperature, titratable acidity, pH, moisture and fat were measured in triplicate. It was checked that the results conformed to current Brazilian legislation, and it was found that 100% of the samples had high... |

| Increasing demand for dairy products in Malaysia is driving government initiatives and structural change in the domestic dairy industry in order to increase competitiveness and self-sufficiency. This study endeavours to investigate the drivers of increasing dairy demand by examining the factors influencing Malaysian consumers‟ consumption and perceptions of various types of dairy products. A survey of 435 respondents was conducted and the data were analysed using logit models. The results indicate that demographic variables such as age and ethnicity as well as other attitudinal variables significantly influence consumers‟ increasing consumption of dairy products. Managerial recommendations for the domestic dairy industry are suggested and policy... |

| Bacillus cereusis an ubiquitous, spore-forming bacteria that can survive pasteurization and the majority of the heating processes used in the dairy industry. Besides, it is a pathogen responsible for different types of food poisoning. One type of foodborne disease caused by B.cereusis the diarrheal syndrome, which is caused by the ingestion of vegetative cells producing toxins in the small intestine. One virulence factor for the diarrheal syndrome is the toxin hemolysin BL (HBL), a three-component protein formed by the L1, L2 and B components. In order to evaluate the presence of diarrheal strains isolated from milk and dairy products, 63 B. cereus isolates were obtained from 260 samples of UHT milk, pasteurized milk and powdered milk, sold in commercial... |

| ABSTRACT The current pricing process of raw milk in Brazil discourages producers from improving milk composition, which affects both yield and quality of dairy products. Furthermore, small and medium-sized dairies face great difficulties when it comes to planning production. Thus, a linear programming model was developed to price the raw milk and determine the optimal mix (combination of quantities) of dairy products that maximizes total contribution margin (TCM) under daily scenarios of high (January) and low (July) raw milk supplies (summer and winter, respectively) by comparing optimal solutions with actual results. The TCM of optimal and actual mixes were higher in January due to the greater availability of raw material. Packaging was a limiting factor... |
