Scattering studies of milk and milk products, which are highly relevant food products on the global market, are often utilized and reported in literature to investigate and understand the subtle microscopic structural differences between dairy samples. These structural features determine the physical properties and ultimately the texture of milk products and, thus, also influence the consumer’s experience. Small-angle neutron scattering is a prominent example, which enables observations of length scales, which convey proteins and fat globules in food-grade milk. In addition, deuteration enables contrast variations between the constituents of dairy products. In this study, we investigate the potential of probing small-angle neutron scattering from milk samples through quantitative neutron dark-field imaging using grating interferometry, to establish the feasibility of studying, in particular, fat globules and milk gel structures with this spatially resolved scattering technique.

Consumption of microbiologically contaminated food is one of the leading causes of diarrheal diseases. Understanding the source of enteric pathogens in food is important to guide effective interventions. Enterobacteriaceae bacterial assays typically used to assess food safety do not shed light on the source. Source-specific Bacteroides microbial source tracking (MST) markers have been proposed as alternative indicators for water fecal contamination assessment but have not been evaluated as an alternative fecal indicator in animal-derived foods. This study tested various milk products collected from vendors in urban Kenyan communities and infant foods made with the milk (n = 394 pairs) using conventional culture methods and TaqMan qPCR for enteric pathogens and human and bovine-sourced MST markers. Detection profiles of various enteric pathogens and Bacteroides MST markers in milk products differed from that of milk-containing infant foods. MST markers were more frequently detected in infant food prepared by caregivers, indicating recent contamination events were more likely to occur during food preparation at home. However, Bacteroides MST markers had lower sensitivity in detecting enteric pathogens in food than traditional Enterobacteriaceae indicators. Bacteroides MST markers tested in this study were not associated with the detection of culturable Salmonella enterica and Shigella sonnei in milk products or milk-containing infant food. The findings show that while Bacteroides MST markers could provide valuable information about how foods become contaminated, they may not be suitable for predicting the origin of the enteric pathogen contamination sources.

The development of food products implies ensuring the optimal composition and ratio of the basic components, as well as their technological compatibility. A priori, the quality of raw materials, the optimal formula of the product and the efficiency of the technological process determine the quality of products, including biological value. The use of whole-cell sensors such as infusoria Tetrahymena pyriformis is most productive for screening biological studies. At present, for a comprehensive assessment there are no data on the use of simplest technology of fermented dairy products and the design of their biological value. The purpose of this research is to develop a methodology for creating whole-milk products of optimal biological value using the express method of biotesting. The research object was yogurt with the ratio of the mass fraction of fat and protein in the range of 0.36 ÷ 1.5, sucrose in the range of 5 ÷ 10%. An express method for determining the relative biological value of fermented dairy products using test organisms and an original methodology for creating whole-milk products of optimal biological value have been developed. A software has been developed to calculate formula of the product optimized for the following indicators: the relative biological value of the product, the cost of raw material and basic materials. The methodology is a tool to assist industry organizations in improving production technologies and quality management systems.

An investigation was conducted to study the involvement of farm women in decision making of different dairy farm activities in Krishna district of Andhra Pradesh .A total of 225 farm women were selected based on their land holding capacity. The study revealed that majority of the women in the study area took part in decision making on most of the dairy farm activities such as choosing the breed of the animal (68%), taking loans (79.11), purchase/ sale of animals (81.33), insurance of animals (77.77%), culling of animals (69.33%), construction of sheds (70.22%), farm expansion (72%), feeding of animals (77.33%), breeding practices ( 66.22%) health care of animals (87.55%), management of new born calves ( 88%), pregnant (87.11%) and sick (86.22%) animals, utility of dung(59.11%), adoption of scientific management practices( 55.55%) and sale of milk(73.33%), whereas majority (69.33%) of the women in study area were taking self decision regarding preparation of milk products. The study showed that among the landless, small and medium farmer categories the participation in decision making regarding choosing the breed of animal(74.66%), purchase or sale of animals(86.66%),insurance of animals (86.65%), culling of uneconomic animals (81.33%), construction of sheds (82.66%), farm expansion (76%), purchase of roughages and feeding of animals (86.66%), breeding practices (81.33%), utility of dung (69.33%) and adoption of scientific management practices (62.66%) was more in landless women compared to small and medium farmer categories.
