Rheological properties of fermented dairy products are very important parameters of the product quality. The behaviour of gel formed during fermentation of milk is influenced by a great number of factors, such as: milk composition, starter culture, flavourings addition, etc. The aim of this research was to examine the influence of fat content, and kombucha inoculum concentration on textural characteristics of fermented milk beverages: firmness, consistency, cohesiveness and viscosity index after production and during 10 days of storage. Higher fat content of beverage affects the firmness, consistency, cohesiveness and viscosity index, while higher amount of inoculum in beverages has an opposite effect on textural characteristics of samples during storage.

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.

Grain-based foods play an essential role in human nutrition. Cereal-based products contain soluble and insoluble dietary fiber, which, by reducing cholesterol levels, reduce the risk of cardiovascular diseases, as well as stabilize digestive functions, preventing diseases of the gastrointestinal tract. Grain products supply the human body not only with energy, but also with protein – by 30-40%, b vitamins by 50-60%, and vitamin E by 80 %. In preliminary studies, 4 types of extruded grain bases were identified from buckwheat, millet, lentils and chickpeas, defined as the basis for fermented dairy products. 20 experiments were carried out in each of the variants using extruded grain bases from buckwheat, millet, lentils and chickpeas with two variants of the milk base – milk with a fat content of 2.5 and 3.2 %. mathematical models of the response function dependences on the selected factors were Obtained, which allowed determining the optimal ratio of ingredients for each of the considered variants. Developed formulation of two dairy products with grain-based extruded from millet based on milk with 2.5% fat and extruded grain-based chickpea based on dairy products with fat content of 3.2%. According to physical and chemical parameters, all samples of fermented milk products met the requirements regulatory documents.

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.

Residual fermented dairy products resulting from process defects or from expired shelf life products are considered as waste. Thus, dairies wastewater treatment plants (WWTP) suffer high input effluents polluting load. In this study, fermented residuals separation from the plant wastewater is proposed. In the aim to meet the municipal WWTP input limits, a pretreatment combining physical–chemical and biological processes was investigated to reduce residual fermented dairy products polluting effect. Yoghurt (Y) and fermented milk products (RL) were considered. Raw samples chemical oxygen demand (COD) values were assessed at 152 and 246 g.L−1 for Y and RL products, respectively. Following the thermal coagulation, maximum removal rates were recorded at 80 °C. Resulting whey stabilization contributed to the removal rates enhance to reach 72% and 87% for Y and RL samples; respectively. Residual whey sugar content was fermented using Candida strains. Bacterial growth and strains degrading potential were discussed. C. krusei strain achieved the most important removal rates of 78% and 85% with Y and RL medium, respectively. Global COD removal rates exceeded 93%.

The aim of the study was to determine the effect of marinating with fermented milk products (buttermilk and sour milk) on the physical characteristics, microbiological quality, and sensory acceptability of Rhode Island Red (RIR) hen meat after the first year of laying use. The hen breast meat was marinated with fermented dairy products, buttermilk and sour milk, by the immersion method for 12 h at 4 °C. The assessed features included the quality of raw and roasted marinated and non-marinated meat in terms of physical characteristics (marinade absorption, water absorption, pH, L*, a*, b* colour, shear strength, texture profile analysis (TPA) test), microbiological parameters, and sensory characteristics. Bacteria were identified by the mass spectrometry method (MALDI-TOF MS Biotyper). Marinating meat with fermented dairy products lightened the colour, decreased the value of shear force, reduced hardness and chewiness, and limited the growth of aerobic bacteria and Pseudomonas spp. Additionally, after heat treatment, the number of identified aerobic bacteria families in the marinated in buttermilk and marinated in sour milk groups was smaller than in the non-marinated muscle group. The sensory evaluation showed a beneficial effect of marinating with buttermilk and sour milk on the tenderness, juiciness, and colour of roasted meat.

Introduction. Many strains used in dairy industry are antagonists of harmful microflora. Logically, a successful combination of several cultures can enhance the bactericidal effect. The present research objective was to develop a fermented milk drink using a prebiotic to stimulate a multicomponent starter culture. Study objects and methods. The research featured pure strains of Bifidobacterium bifidum strain No. 791 and Lactobacillus acidophilus (VZ-AP), as well as Bio-fi Pro WR 400 beet fiber. The study involved standard and conventional research methods. Results and discussion. The first stage defined the optimal ratios of B. bifidum and L. acidophilus for a two-component starter culture, as well as the optimal production method and their antibiotic activity. The second stage featured the functional and technological properties of the prebiotic beet fiber and its effect on the development of microorganisms in the starter. The study resulted in the main production parameters and a technological scheme for the production of fermented dairy product. Conclusion. The paper introduces a new technology for production of a functional fermented milk product fortified with probiotics and prebiotics, as well as approved technical documentation. The new functional fermented dairy product was based on a starter culture that combined a liquid concentrate of B. bifidum strain No. 791 and a starter culture of L. acidophilus (VZ-AP). The optimal ratio of microbial cultures was 5:1, respectively. The starter strain proved to have a high antibiotic activity. Prebiotic beet fiber Bio-fi Pro WR 400 could be recommended as a product stabilizer at the optimal amount of 0.7% by weight of standardized milk.

Functional food is positioned above the traditional, with the potential to improve human health. Thanks to very good physico-mechanical and barrier properties polymers became very popular in food industry as a packaging materials. Wild range of fermented dairy products could be packed in this packaging materials according to their?s inertness as well. Functional milk beverage was obtained from milk with 0,9% milk fat content by applying 10% v/v of kombucha?s inoculum cultivated on a black tea sweetened with sucrose. The beverage was packed in a different packaging materials: polyamid-polyethylen (PA/PE) coextruded foil bags and polyprophylen (PP) cups closed with aluminium (Al) foil lids under atmospheric conditions (ATM). Beverages were storaged for 15 days at 4?C. The quality of kombucha inoculum, milk and obtained kombucha fermented milk beverage were analysed. Characterization of the packaging materials was done by investigating physico-mechanical, barrier and structural properties. The composition and changes in the headspace atmosphere, after production and during the storage, were analysed. The influence of packaging material properties and packaging conditions on the biochemical transformations of the milk?s components (the content of: lactose, L-lactic acid, D-galactose, ethanol, B1 and B2 vitamins) influenced by kombucha starter were analysed as well. On the bases of the obtained results of characterisation of packaging materials, it can be concluded that PA/PE and PP materials are proper to be used for analysed beverage?s packaging. Also, there is no significant difference in content of components which were quantified, between analysed materials in correlation with the packed fermented milk beverage.
