Milk-containing products occupy a large place in the range of popular products. Replacing milk fat or protein with vegetable fat can reduce the biological value of the product and its organoleptic properties. the effect of direct application starter cultures on raw materials that use functionally necessary ingredients (structure-forming agents, salt, sugar, etc.), food additives (thickeners, stabilizers, preservatives, etc.) and a variety of non-dairy components (non-dairy fats, non-dairy proteins, meat products, fruits, vegetables, spices, herbs, nuts, etc.) is ambiguous. The paper deals with the use of homogeneous and combined starter cultures in the production of fermented milk products from natural and normalized milk and milk-containing mixtures with a substitute for milk fat. The introduction of components of plant origin into the product leads to a decrease in the content of milk protein in the mixtures, which in turn leads to the formation of clots with a non-uniform consistency. Slow acid formation in milk-containing mixtures indicates a decrease in milk sugar in them with this type of normalization in fat, relative to the normalized milk according to the classical technology. This pattern was revealed both when using starter cultures on lactic acid thermophilic streptococci, and on combined starter cultures. In this paper, it is proposed to use Streptococcus salivarius subsp in ferments for milk-containing mixtures. thermophilus strain ST-95. The introduction of the ST-95 strain into the starter culture made it possible to obtain from the milk-containing mixture a fermented milk product with well-pronounced organoleptic properties, a stable clot structure and sufficiently high taste properties. The greatest positive effect was obtained on combined ferments.

Functional Orientation

Nowadays in the dairy industry, the combination of raw materials of plant origin with a dairy base can be noted. Received dairy products have a functional orientation. The product line is expanding with every new filler. This allows the consumers to choose the product they like. The properties of the starter cultures used for fermented milk products were studied by the authors, and the choice of starter culture was carried out. The starter culture “Narine” was used in the development of a method for the fermented milk drink production. The choice of starter culture was made taking into account the more pronounced bactericidal antibiotic properties of acidophilus bacillus in relation to some harmful and pathogenic bacteria compared to other starter cultures. The choice of flavor component was carried out to expand the assortment of fermented milk drink. Experiments showed that yellow and orange colors affect the perception of the buyer positively. They help to cope with fatigue and depression. They are closer to the natural colors of dairy products; therefore, in the production of this fermented milk drink, the orange filler in the form of syrup was used. Mass fraction of orange syrup ranged from 1 to 7%. The optimal dosage was 5%. With the help of it the drink had a clean sour-milk taste and the orange smell, a uniform consistency and a yellowish color. The recipe was selected and the technology of fermented milk drink, which involves the introduction of orange syrup in the fermented product, was developed. The main organoleptic, physico-chemical and microbiological indicators of the fortified fermented milk drink were studied in the work. The compliance of the quality indicators of the fermented milk drink with the requirements of the Technical Regulations of the Customs Union “On the Safety of Milk and Dairy Products” (TR TS 033/2013) was determined.

The traditional yogurt starter, i.e. Staphylococcus thermophilus and Lactobacillus bulgaricus, has always been used to bring about the lactic acid fermentation during manufacture of concentrated yogurt known in Egypt as “Labneh”. Different combinations of some strains of Enterococcus faecalis, isolated from Laban Rayeb (a type of fermented milk), in combination with a certain strain of Lactobacillus bulgaricus were used to produce a Labneh-like product. Chemical, microbiological and organoleptic properties of the Labneh-like product were assessed and compared to the characteristics of Labneh processed traditionally by two different dairy plants in Egypt. All treatments showed similar changes during storage at 5 ± 1°C for 28 d. Total solids, fat, titratable acidity and pH values coincided with those of Labneh. Some components increased until the seventh day, i.e. acetaldehyde and diacetyl, while other features, such as the ratio of soluble nitrogen/total nitrogen and tyrosine, increased until the fourteenth day of storage. Thereafter, no marked variations occurred. However, a decrease in tryptophan content of all products occurred during the storage period. Total viable count and count of lactic acid bacteria of Labneh-like product as well as Labneh increased until the end of the second week of storage and then decreased. Coliforms, yeasts and molds and psychrotrophic bacteria were detected in some fresh and stored samples. The starter culture which consisted of 1.5% Enterococcus faecalis 19 and 1.5% Enterococcus faecalis 22 was used successfully to manufacture a Labneh-like product with high acceptability when fresh or refrigerated at 5 ± 1°C.

Several combinations of an amine-negative Lactobacillus sakei strain, along with proteolytic Staphylococcus carnosus or Staphylococcus xylosus strains, were used to study the influence of mixed starter cultures on biogenic amine production during the manufacture of dry fermented sausages. Changes in pH, water content, proteolysis, microbial counts, and biogenic amine contents were simultaneously examined in a spontaneously fermented batch and in three mixed starter-mediated batches. A double-controlled microbial charge initially inoculated as mixed starter culture of L. sakei and Staphylococcus spp. (all amine-negative strains) drastically reduced tyramine, cadaverine, and putrescine accumulation. No production of other aromatic amines such as histamine, phenylethylamine, or tryptamine was observed in any batch. The polyamines, spermine and spermidine, were found in raw materials and their levels decreased slightly in the spontaneously fermented batch. No correlation between proteolysis and biogenic amine production was observed. The use of proper technological conditions favoring starter development and the use of the raw materials with good hygienic quality make it possible to produce fermented sausages nearly free of biogenic amines.

Abstract Lonicera caerulea L., also known as honeysuckle berries, are rich in biologically active compounds, which makes them a valuable raw material for the development of functional foods. The objects of the research were three honeysuckle cultivars (‘Zoluška’, ‘Siņaja Ptica’, ‘Goluboje Vereteno’), four genotypes (No 2A; No 3; No 5; No 8) and kefir, enriched with various amounts (3–10%) of fruit puree. Physical and chemical analyses to determine the qualitative indicators of raw materials and products were performed. The degree of liking of kefir was assessed using sensory analysis: hedonic and line scales. The results obtained showed that among the cultivars the highest content of anthocyanins (1103.5 mg·100 g−1), total phenols (693.3 mg·100 g−1), flavonoids (753.9 mg·100 g−1), and tannins (1.6 mg·100 g−1), were found in ‘Siņaja Ptica’ berries, while among the genotypes, berries of No 8 had the highest concentration of the aforesaid compounds. Both samples also showed the highest antiradical activity: ABTS+• on average by 71.7% and DPPH− by 43.7%. According to the sensory evaluation, kefir with 10% honeysuckle puree was rated the highest. Honeysuckle berries could be used as a promising source of natural anti-oxidants in future research aimed at developing different new products that could meet consumer expectations.

Main problem: Modern manufacturers of products, by the current market conditions, should take care that their products are competitive and attractive in consumer terms, but also the economic efficiency of its production is important. In this regard, in the production of food products, including meat, the use of various additives that allow to make products with more pronounced organoleptic properties, increased shelf life, increased nutritional and biological value are used. Analyzing the products presented on the market, it was revealed that the use of food additives of chemical origin is more than common among today's manufacturers, because they allow producing products that are lower in cost by improving the taste and aroma properties of the product, using low-quality raw materials or replacing natural raw materials with artificial components. Despite the widespread use of such additives, they still remain not sufficiently studied. Purpose: It is necessary to revise the traditional range of meat products in the country by direction of increasing the volume of production of products from natural and chopped meat with a variety of attractive organoleptic characteristics. It is a modern principle of organization and management of food industry enterprises. Methods: In this regard, the use of new natural ingredients in the production of meat sausage products becomes an urgent task. Considering the field of food technologies, it should be noted that currently there is a tendency to increase the consumption of food enriched with natural additives. Results and their significance: Based on our research, result was obtained showing that chemical food additives negatively affect the microflora of the gastrointestinal tract. As a result, it was decided to develop a new type of sausage products using natural additives, such as rosemary and blueberry fruits. This article provides a justification for their use in the production of sausage products as an alternative to various chemical food additives that can have a negative impact on the human body.

Minced Meat

When creating meat products, one of the main indicators is the biological value of the product. The biological value of proteins depends on the degree of their assimilation, in animal proteins is greater than in vegetable. More than 90% of amino acids are absorbed from animal proteins in the intestine. An important indicator of the biological value of proteins is their attack by digestive enzymes - the property to be hydrolyzed with the participation of enzymes in the gastrointestinal tract.Enzymatic methods for determining the biological value of a protein are one of the simplest and at the same time objective methods for determining its ability to be broken down by proteolytic enzymes in the gastrointestinal tract.The article presents a study on the biological value of minced meat semi-finished products. For the studies we used chopped semi-finished products (cutlets) control sample and three test samples with partial introduction into the formulation of food additives based on animal and vegetable raw materials - 0.5 %, 0.75 % and 1.0 %, respectively. Hydration of the additive is 1:15. The food supplement contains g / 100 g: sodium alginate - 60, whey protein - 16, soy fiber - 24. To determine the biological value of the products by the enzymatic method used a device for hydrolysis of proteins. The essence of the method is a six-hour hydrolysis by enzymes of a sample of the finished product. The first stage is fermentation with pepsin (3 hours), the second stage is trypsin (3 hours). With hourly selection of hydrolysis products to determine the degree of digestibility at a certain stage of the study. It is proved that the addition to the recipe of chopped semi-finished food mixture is advisable, as it allows to obtain chopped semi-finished product with better digestibility. The digestibility of the experimental samples was slightly higher than the control. The digestibility index for control was – 69 %, and for experimental – 68-74 %. Therefore, according to research, we can say about the feasibility of using additives in the production of minced meat semi-finished products with a share of replacement of basic raw materials from 8 % to 16 %.

This article aims to evaluate the influence of probiotic microorganisms and pregastric lipase on organoleptic and biochemical characteristics of soft cheese made from a mixture of milk and buttermilk. The study was designed to determine how the temperature and exposure at this temperature affect the growth and development of lactose and bifidobacteria, as well as their quantity in the finished product. In order to increase the biological and nutritional value of the developed soft cheese, protein-carbohydrate raw materials rich in vitamins A, B12, D, E, phosphate and minerals were introduced into the production mixture. The addition of buttermilk increased the biological value of the product and improved its consistency. The taste and consistency of cheese was improved by a pregastric lipase preparation, widely used in the cheesemaking industry for production of various cheeses with high and low temperatures of the second heating. As a result of directed lipolysis, the finished product accumulates free fatty acids and diacylglycerols, acting as plasticizers and affecting the texture and organoleptic characteristics of the cheese. The results show that combining buttermilk and milk in an optimal ratio and addition of lipase produce a product with the best physicochemical parameters and a maximum evaluation of organoleptic characteristics. In the presence of a probiotic starter culture (provided there is a ready-made substrate), an active synthesis of enzymes necessary for the complete hydrolysis of milk fat begins. This all creates a functional product.

Consumers associate the finished meat products with negative health effects that are connected with a high content of saturated fat; food additives and carcinogenic substances. Consumer demand for functional products with a reduced amount of saturated fats is growing. The purpose of scientific research was justification the functional properties of sausage bread manufactured using protein-fatty emulsions based on flour made from flax-LM-98 Raziol; Ural. In the recipe of sausage bread 15% of fat and meat raw materials were replaced by the protein-fatty emulsion based on flax flour. It is established: addition of emulsion contributes to a more pronounced flavor and aroma, attractive appearance and drawing on a cut of meat products. Analysis of the chemical composition meat products showed an increase in fat content on 12.7-23.7%; soluble and insoluble dietary fibers concentration; calcium and phosphorus content. The experiment proved the high biological value of lipid fraction in sausages containing flax flour. Content of polyunsaturated fatty acids increased by 15.8–29.2%, concentration of (-3 fatty acids increased 3.7–7.7 times. The ratio of (-3:(-6 fatty acids in samples with flax flour of Ural grade amounted to 1:1.3, consumption of 50 g sausages satisfies the daily need in (-3 fatty acids by 60.8%. The ratio of (-3:(-6 fatty acids in samples with flax flour of Raziol grade amounted to 1:3.3; consumption of 50 g sausages satisfies the daily need in (-3 by 29.5%. Sausage bread containing 5.6% flax flour Ural and Raziol varieties should be attributed to functional foods, due to the high content of functional component and the ability to satisfy more than 15% of the daily need for (-3 fatty acids.
