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.

Milk And Dairy Products

Современный рынок молочной продукции претерпевает существенные изменения, в основе которых лежит тенденция на удешевление продукции. Российские молочные продукты, произведенные из классического сырья по традиционным технологиям, зачастую подвергаются фальсификации продуктами с пониженными массовыми долями жира и белка, заменой молочных компонентов и живых заквасочных культур вследствие отсутствия системы идентификационных характеристик. Реформой технического регулирования, проведенной в Российской Федерации в 2000 году, правила идентификации как способ отнесения продукта к определенной группе продукции посредством сопоставления его характеристик с установленными были законодательно закреплены на федеральном уровне. В настоящее время идентификация служит неотъемлемой частью оценки (подтверждения) соответствия продукции и является главным средством борьбы с фальсификацией. Критериями идентификации выступают регламентированные показатели продукта. Технический регламент Таможенного союза 033/2013 «О безопасности молока и молочной продукции» включает понятие «национальный молочный продукт», однако критерии идентификации этой группы продукции отсутствуют. Целью исследования был поиск уникальных характеристик российских молочных продуктов для их идентификации среди аналогичной продукции. В качестве метода был применен ретроспективный анализ литературы с глубиной поиска до 1930-х гг. Установлено, что в качестве критериев идентификации молочных продуктов использовали не только сырьевой и технологический признаки, но и упаковку. Выявленные критерии будут положены в основу формирования системы идентификации российских молочных продуктов. The modern dairy market is undergoing significant changes, which are based on the trend towards cheaper products. Russian dairy products made from classical raw materials using traditional technologies are often falsified by products with reduced mass fractions of fat and protein, replacing dairy components and live starter cultures due to the lack of an identification system. The reform of technical regulation carried out in the Russian Federation in 2000, the identification rules as a way of classifying a product as a specific product group by comparing the characteristics with the established ones were legally fixed at the federal level. Currently, identification is an integral part of the assessment (confirmation) of product conformity and is the main means of combating falsification. Identification criteria are regulated product indicators. The technical regulation of the Customs Union 033/2013 «On the safety of milk and dairy products” includes such a concept as «national dairy product», however, there are no criteria for identifying this group of products. The aim of the research was to search for unique characteristics of Russian dairy products and classical technologies that distinguish them from similar products. As a method, a retrospective analysis of the literature with a search depth of up to the 1930s was used. It was established that not only raw and technological characteristics, but also packaging were used as criteria for identifying dairy products. The identified criteria will be the basis for the formation of an identification system for Russian dairy products.

19Streptococcus thermophiluswith high exopolysaccharide production were isolated from traditional Chinese fermented dairy products. The exopolysaccharide and viscosity of milk fermented by these 19 isolates were assayed. The strains ofStreptococcus thermophiluszlw TM11 were selected because its fermented milk had the highest exopolysaccharide content (380 mg/L) and viscosity (7716 mpa/s). ThenStreptococcus thermophiluszlw TM11 was combined withLactobacillus delbrueckiisubsp.bulgaricus3 4.5 and the combination was named SH-1. The quality of the yogurt fermented by SH-1 and two commercial starter cultures (YO-MIX 465, YF-L711) were compared. It was shown that the exopolysaccharide content of yogurt fermented by SH-1 was similar to that of yogurt fermented by YF-L711 and significantly higher than YO-MIX 465 (p<0.05). In addition, the yogurt fermented by SH-1 had the lowest syneresis (8.5%) and better texture and sensory than the samples fermented by YO-MIX 465 and YF-L711. It manifested that the selected higher exopolysaccharide production starter SH-1 could be used as yogurt starter and reduce the amount of adding stabilizer, which can compare with the imported commercial starter culture.

Starter cultures are those microorganisms (bacteria, yeasts, and molds or their combinations) that initiate and carry out the desired fermentation essential in manufacturing cheese and fermented dairy products such as Dahi, Lassi, Yogurt, Sour cream, Kefir, and Koumiss amongst others. Starter culture is defined as “an active microbial preparation, deliberately added to initiate desirable changes during preparation of fermented products”. Starter cultures have a multifunctional role in dairy fermentations. The production of lactic acid by fermenting lactose is the major role of dairy starters. The acid is responsible for development of characteristic body and texture of the fermented milk products, contributes to the overall flavour of the products, and enhances preservation. Beyond the horizons of their conventional role in acid, flavour and texture development, they are being looked up on as burgeoning “cell factories” for production of host of functional biomolecules and food ingredients such as biothickeners, bacteriocins, vitamins, bioactive peptides and amino acids.

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.

Acid Fermentation

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.

In recent decades, the majority of outbreaks of listeriosis with a high percentage of deaths was caused by the consumption of food products, including meat and meat products. One of the main principles of prevention of listeriosis in humans and animals is a constant quality control of food and feeds. The district of the Ussurisk city specializes mainly in the production of agricultural products. Meat production work on the raw materials of local origin, and the imported meat is also used. There was executed a study concerning the possibility of the contamination of meat products of Listeria monocytogenes on the territory of the agricultural province of the district of the Ussurisk city for the period from 2012 to 2015. A total of 21491 sample products were investigated according to rules “Common sanitary and epidemiological and hygienic requirements for goods subject to sanitary-and-epidemiologic supervision (control)” of the Customs Union (Chapter II, section 1) and the Technical Regulations of the Customs Union № 880 “About security of food “(Appendix 1). The presence of 45 positive cases of L. monocytogenes was revealed, at that the most of them have been found in meat products and poultry meat. Observations of the occurrence rate of L. monocytogenes in meat of the imported production for a number of years show these the pathogenic bacteria to be isolated every year in 40% - 66.6% of cases (of all positive cases of isolation from meat). This meat was imported mainly from countries such as Brazil, Paraguay, New Zealand, Austria, England, Uruguay. A large proportion of meat and meat products, contaminated by L. monocytogenes enters the territory of Primorsky Kray from Latin America. It is important to note that meat and meat products contaminated by these pathogens were also produced in the territory of the district of the city of Ussurisk. In connection with it there is obvious the need as for further continuation of monitoring products on the market, as a survey of agricultural animals of private and public farms in the district.

In this study, the effects of kombucha inoculum as non-conventional starter culture on fatty acids composition of fermented milk, compared to a commercial probiotic (ABT-7) and yoghurt (YF-L812) starter cultures, during 21 days of storage was investigated. Fatty acids composition was determined by gas chromatography-mass spectrometry after the previous extraction of lipids and derivatization. The atherogenic (AI) and thrombogenic (TI) indices determined on the basis of fatty acids composition have been used for evaluation of the nutritive lipid quality of the fermented dairy products. The most significant levels of fatty acids in fermented milk products were palmitic, followed by oleic, stearic and myristic fatty acids. Fermented milk products were characterized by low atherogenic (2.14-2.39) and thrombogenic (2.91-3.18) indices, suggesting their consumption could have a favorable effect on human health. The AI and TI were comparable during the storage of fermented milk samples. Starter culture did not affect the health-related fatty acid composition of fermented milk products during storage.
