Рассмотрена проблема сохранения и направленного регулирования качества молочной сыворотки путем кондиционирования. Предложены три направления переработки молочной сыворотки на основе кондиционирования: полное использование в нативном и/или модифицированном виде, извлечение компонентов, синтез производных. В рамках каждого из направлений разработаны нанобиомембранные технологии, по которым получены молочные продукты нового поколения: пребиотический концентрат Лактобел для кормовых и пищевых целей на основе изомеризованных сгущенных молочной сыворотки и обезжиренного молока с оптимизированным составом при соотношении 60 : 40 соответственно по массовой доле сухих веществ компонентов, ЛипКА – липидный казеиново-альбуминный концентрат и линейка продуктов бренда МиЛа с пониженным содержанием лактозы: из творожной сыворотки – МиЛа-С; из обезжиренного молока – МиЛа-О; из смеси творожной сыворотки и обезжиренного молока – МиЛа-ОС. Установлено, что сочетание ферментативного гидролиза лактозы со сквашиванием молочнокислыми бактериями позволяет получать кисломолочные продукты с низким содержанием молочного сахара, которые целесообразно рекомендовать для включения в рацион лактозозависимых людей. Разработанные по инновационным технологиям продукты на основе молочной сыворотки являются функциональными продуктами нового поколения для здорового питания. The problem of preservation and directed regulation of whey quality by conditioning is considered. Three directions of processing of whey on the basis of conditioning are offered: full use in native and/or modified form, extraction of components, synthesis of derivatives. Within each of the directions nanobiomembrane technologies are developed, on which dairy products of new generation are obtained: prebiotic concentrate of Lactobel for feed and food purposes on the basis of isomerized condensed milk whey and skimmed milk with optimized composition in the ratio of 60 : 40, respectively, by the mass fraction of dry matter components, LipKa – lipid casein-albumin concentrate and a line of products of the brand MiLa with a reduced content of lactose: from curd serum – MiLa-S; from skimmed milk – MiLa-O; from a mixture of curd whey and skim milk – MiLa-OS. It was found that the combination of enzymatic hydrolysis of lactose with lactic acid bacteria fermentation allows to obtain dairy products with a low content of milk sugar, which is advisable to recommend for inclusion in the diet of lactose-dependent people.

This study was conducted to develop a selective and sensitive method for the determination of bisphenol A (BPA) levels in milk and dairy products. A method based on solvent extraction with acetonitrile and solid-phase extraction (SPE) was developed for the analysis of BPA in milk, yogurt, cream, butter, pudding, condensed milk, and flavored milk, and a method using two SPE cartridges (OASIS HLB and Florisil cartridge) for skim milk was also developed. The developed methods showed good recovery levels (77 to 102%) together with low detection limits (1 μg/liter for milk, yogurt, pudding, condensed milk, flavored milk, and skim milk and 3 μg/liter for cream and butter). These methods are simple, sensitive, and suitable for the analysis of BPA in milk and dairy products. When 40 milk and dairy products were analyzed by the proposed methods, BPA was not identified in noncanned products, but its levels ranged from 21 to 43 μg/kg in canned products, levels that were 60- to 140-fold lower than the migration limits in the European Union and Japan.

1. The biological value of proteins at an 8% level of protein intake measured on rats by the method of Mitchell (7, 10) was 52 for white bread of 73% extraction, 76 for Cheddar cheese, 75 for a mixture of both foods when each supplied 50% of the protein, and 67 when the two sources of protein were given on alternate days. The true digestibilities were, respectively, 99, 100, 98 and 99.2. Similar experiments with dried skim milk and dried cooked potatoes yielded biological values of 71 for potato, 89 for milk, 86 for the mixture and 81 for the substances fed separately on alternate days. The true digestibilities were, respectively, 82, 90, 82 and 87.3. An attempt to carry out experiments of the same type with dried whey and dried potato failed because of deaths of some rats receiving the whey diet, probably because of its high content of lactose. A biological value of 76 was obtained for the potato proteins and of 70 for a mixture of whey and potato in which whey supplied 25% of the protein. The true digestibilities were, respectively, 82 and 68.4. The biological value and the true digestibility of the proteins of a sample of edible soya-bean flour were, respectively, 73 and 90.5. It is concluded that there is a marked supplementary relationship between the proteins of milk and potato and those of bread and cheese when the members of each pair supply equal amounts of protein and when they are given together. No supplementary relationship is exhibited when the sources of protein are given separately on alternate days.

Abstract Two lactating dairy cows per group were fed selected pesticides dissolved in organic solvents and mixed into a grain concentrate for a two week period. The reference pesticides used in this study were dieldrin; a mixture of heptachlor, DDT, and lindane; toxaphene; chlordane; endosulfan (Thiodan); and dicofol (Kelthane). The milk from these contaminated cows was collected and processed into the following dairy products: pasteurized whole milk, 30% cream, butter, spray-dried whole milk, condensed whole milk, sterilized condensed whole milk, and Cheddar cheese. The byproducts (skim milk, buttermilk, and Cheddar cheese whey) from manufacturing these products were also saved for subsequent analysis. The residues in these dairy products and byproducts were extracted, cleaned up, and analyzed by electron capture gas chromatography. The 30% cream, condensed milk, and pasteurized milk were analyzed at 0, 7, and 14 days and Cheddar cheese, spray-dried milk, butter, and sterilized condensed milk after storage for 0, 3, and 6 months. The results indicated that, in general, the pesticides used were very stable for ordinary dairy processing operations and remained essentially unchanged even after storage at refrigeration and room tempera-tures for 6 months. However, dieldrin, lindane, and chlordane showed a 27, 34, and 11% decrease, respectively, for spray-dried products and the concentration of dicofol showed a slight decrease in the sterilized condensed whole milk products, whereas the concentration of DDE extracted from the products stored 3 and 6 months was generally less than the amount extracted initially. In manufacturing Cheddar cheese, most of the pesticides showed some bacteriostatic or bactericidal action against starter microorganisms. Generally the pesticide residues were found in greater concentration (on a fat basis) in the skim milk, buttermilk, and whey than in products from which these were derived. This might be attributable to the affinity of the residues for the lipoprotein portion of the products. Concentrations of dieldrin and toxaphene increased slightly during storage of the milk and milk products, suggesting that a reorientation occurred.

The present paper features processes of serum biotransformation. The serum was obtained from triticale extract and pea flour after protein concentrates of increased biological value had been extracted. The research objective was to obtain microbial and vegetable feed concentrates by using a composition of Saccharomyces cerevisiae121 yeast and the yeast-like fungus Geotrichumcandidum 977. The mass fraction of protein in the two-component composites was 75–80% of the dry matter. The score of the first and the second limiting amino acids (lysine and threonine) equaled 103–113%, and that of the third acid (sulfur- containing) was 71–72%. The chemical composition of the composites corresponded to the ‘Concentrates’ group; the values of their functional and technological properties were typical of concentrates from other types of grain crops. The study revealed some cultures that are able to actively develop in serum, which is a secondary product of processing the extract after protein isolation. A symbiotic ferment was prepared from the fungus Geotrichumcandidum 977 and the yeast Saccharomyces cerevisiae 121, which ensures the growth of biomass in a carbohydrate- and nitrogen-containing medium. Proteins were isolated under the action of amylase, glucoamylase, cellulose, and xylanase. The amount of high-molecular compounds (dextrins) and trioses (raffinose) released from the interaction with protein and non-starch polysaccharides decreased 2–4 times in the solution. The amount of glucose, disaccharides, xylose, and galactose increased 2–10 times, compared with the original extracts. The serum remaining after the removal of the main mass of the protein was enriched with low molecular weight mono- and oligosaccharides, which positively affected the growth of microorganisms. The mass fraction of proteins in the microbial-vegetable composite obtained from the extract with the triticale proteins and pea flour ratio of 1:5 was 15% higher than at the ratio of 1:3. Microbial and vegetable concentrates with a mass fraction of protein of 55.8–75.1% of dry matter can be used in fodder production as a protein-carbohydrate additive. Protein composites made of protein triticale and peas with a complementary amino acid composition can improve the biological value and performance of food products.

To provide the population with high-quality milk and dairy products, to increase the production of milk fat, protein, carbohydrates and other substances, it is necessary to take measures to improve the chemical composition of milk. The article presents the results of research on the composition and properties of different portions of cow's milk of morning and evening milking. It was found that the composition of milk is different and depends on the portions. The mass fraction of protein, lactose, salt, skimmed milk solids is high in the milk of the first portion, the mass fraction of fat and milk solids is high in the last portion. The milk density of the first portion is maximum, and the last portion is minimal. It was found that depending on the portions, the composition of morning milking milk changes more than the composition of evening milking milk.

   Currently, cottage cheese is one of the leading dairy products for infants’ nutrition. Today, the urgent task is to expand the range of sour-milk products by developing a technology for cottage cheese production with the addition of a fruit filler. The object of research is cottage cheese for the diet of children over six months. The cottage cheese is produced from whole milk subjected to high-temperature treatment with the use of starter microorganisms and with the addition of fruit filler “Banana”. The children’s curd recipe developed by the authors included the following raw materials and components: milk with the mass fraction of fat 3.4 %, skim milk with the mass fraction of fat 0.05 %, direct injection starter Flora C-170, fruit filler “Banana”. Production technology included the following stages: receiving and preparing raw materials, normalization of milk, homogenization, pasteurization and cooling of the normalized mixture, fermentation, ultrafiltration of curd clot, cooling and ripening of the product. The authors conducted laboratory studies of cottage cheese to assess the quality and safety of the resulting product. The products meet the requirements of GOST 32927-2014 for organoleptic indicators: taste and smell, appearance and consistency, colour. The products also meet the needs of the Technical Regulations of the Customs Union (TR CU) 033/2013 “On safety of milk and dairy products” in terms of microbiological and antibiotic content.
