Quality of milk consumed in Samara region: An analysis of milk physical and chemical characteristics

Abstract

Objectives an analysis of physical and chemical indicators of milk quality produced under the most popular brands in the Samara region. Material and methods. The study was selective and prospective, focused on the physical and chemical indices of milk quality. The sampling was based on the results of the assessment of the frequency of consumption of various brands of milk by the population of the Samara region. The analysis included five samples of milk of different brands, purchased in the retail food store chain, and assessed their various physical and chemical indicators. All measurements were performed in accordance with the regulatory documentation. Results. Only 1/3 part of respondents (32.6%) included milk in their daily diet. All five milk samples subjected to physical and chemical examination met the requirements of the current regulatory documentation. However, in assessing the nutritional value of the samples by mineral composition, it was found that the actual content of phosphorus and calcium is significantly lower than the values of the corresponding indicators set out in the handbook "Chemical composition and calorie content of Russian food products" that is used as a guide by nutrition specialists. Conclusion. Milk purchased in the food store chain met the safety requirements for physical and chemical indicators. The reduced level of milk consumption among the population of the Samara region requires management decisions. The actual chemical composition of this product, which has regional and seasonal characteristics, should be taken into account in the development of diets for defined population groups.
