Abstract The most important factor determining human health is nutrition. Functional products containing many valuable ingredients contribute to the strengthening and maintenance of human health. In this regard, over the years, the development of technology for the production of such products does not lose its relevance. The authors selected the composition and ratio of probiotic microflora in the composition of a complex starter culture for the production of a functional fermented milk product. Two variants of complex starter culture were selected containing Streptococcus salivaris subsp. thermophilus, Bifidobacterium subsp. lactis (BB-12) and Lactobacterium casei subsp. casei in a ratio of 4: 1: 1 and Streptococcus salivaris subsp. thermophilus, Bifidobacterium bifidum and Lactobacillus acidophilus in a 4: 1: 1 ratio. The paper considers the influence of individual technological factors on the quality formation of the finished product, such as the dose of the prebiotic galactooligosaccharides (GOS), the dose of the concentrate of whey protein (CWP) and the fermentation temperature of the milk mixture. The following technological factors of production have been established: doses of introduced components (GOS - (1 ± 0.1) %, CWP (2.0 ± 0.5) % and the fermentation temperature of the mixture (38 ± 2) °C. The results of the study will be used further in the development of technology for a functional fermented milk product.

Кисломолочные продукты приобретают популярность во всем мире благодаря их полезным и функциональным свойствам. Проблема разработки и широкого использования кисломолочных продуктов приобретает огромное значение в период пандемии и экологического кризиса. Полезные свойства кисломолочных продуктов зависят от состава заквасок, используемых для их производства. Вид и количество используемых в составе закваски штаммов обуславливает бифункциональный эффект пробиотического кисломолочного продукта. Из молочнокислых бактерий Lactobacillus являются наиболее изученными пробиотическими микроорганизмами с широким спектром физиолого-биохимических свойств. Для разработки кисломолочного продукта была использована ассоциация заквасочных культур, состоящая из Lactobacillus rhamnosus TR, Lactobacillus reuteri LR1 и Lactobacillus acidophilus H-9 в соотношении 1:6:1, которая обладает функциональным потенциалом. В работе научно обоснованы технологические режимы производства пробиотического кисломолочного продукта c использованием указанной выше ассоциации культур, которая обеспечивает сквашивание пастеризованного обезжиренного молока за 7-8 ч при внесении 5-7 % инокулята, обеспечивая определенные органолептические показатели. При этом количество клеток пробиотических культур составляет для L. acidophilus Н-9 1,1×10 КОЕ/см, для L. reuteri LR 1 (2,1±1,3)×10КОЕ/см, для L. rhamnosus TR (1,37±0,98)×10 КОЕ/см. Показано, что разработанный кисломолочный продукт обладает антагонистической активностью к S. aureus АТСС 6538 и Salmonella typhimurium NCTC 00074, а также антиоксидантной и АПФ-ингибирующей активностью, что характеризует его бифункциональные свойства. Диаметр зоны ингибирования роста S. aureus АТСС 6538 составляет 15,25±0,35 см, а Salmonella typhimurium NCTC 00074 10,5±0,71 см. Антиоксидантная активность разработанного продукта составляет 570,64±18 мкмоль TЭ/мг, а АПФ ингибирующая активность - IC 1,23±1,6 мг белка/см. Fermented milk products are gaining popularity all over the world due to their useful and functional properties. The problem of the development and widespread use of fermented milk products becomes of great importance during a pandemic and an ecological crisis. The beneficial properties of fermented milk products depend on the composition of the starter cultures used for their production. The type and quantity of strains used in the starter culture determine the bifunctional effect of the probiotic fermented milk product. Of the lactic acid bacteria, Lactobacillus is the most studied probiotic genus with a wide range of physiological and biochemical properties. For the development of a fermented milk product, an association of starter cultures was used, consisting of Lactobacillus rhamnosus TR, Lactobacillus reuteri LR1, and Lactobacillus acidophilus H-9 in a ratio of 1: 6:1, which has a functional potential. The work scientifically substantiates the technological modes of production of a probiotic fermented milk product using the above-mentioned association of cultures, which ensures the fermentation of pasteurized skim milk in 7-8 hours with the introduction of 5-7 % inoculum, providing certain organoleptic characteristics. In this case, the cells number of probiotic cultures for L. acidophilus H-9 is 1.1×10 CFU/cm, for L. reuteri LR 1 (2.1±1.3)×10 CFU/cm, for L. rhamnosus TR (1.37±0.98)×10 CFU/cm. It was shown that the developed fermented milk product has an antagonistic activity to S. aureus ATCC 6538 and Salmonella typhimurium NCTC 00074, as well as antioxidant and ACE-inhibiting activity, which characterizes its bifunctional properties. The diameter of the growth inhibition zone for S. aureus ATCC 6538 is 15.25±0.35 cm and for Salmonella typhimurium NCTC 00074 10.5±0.71 cm. The antioxidant activity of the developed product is 570.64±18 μmol TE/mg, and ACE inhibitory activity IC50 1.23±1.6 mg protein/cm.

In recent years, there has been a trend to develop and produce special products. Improving food technology through the use of hydrated oatmeal makes it possible to enrich fermented milk products with proteins, dietary fiber, trace elements and vitamins. Oat flakes were used as a nutrient medium for microorganisms in a fermented milk product. Lactobacilli and acidophilus bacillus produce organic acids which leads to the inhibition of the vital activity of pathogenic microorganisms. The use of hydrated oat flakes in an amount of 6% at the stage of fermentization at a temperature of 420 ° C has a positive effect on quality of the fermented milk product (yogurt) and development of lactic acid bacteria.

Fermented milk product "Laban" in Libya is one of the most a traditional fermented milk product consumed a refreshing drink, particularly in the warm season The average values of the physicochemical including titratable acidity, pH, total solids, and fat were 0.73%, 4.16, 8.12%, and 1.54% respectively. Coliform, yeast and mold counts were 21×10⁴, 39×10⁴, and 41 ×10³ cfu/ ml., respectively. Most strains of coliform bacteria were Serratia odorifera, Escherichia coli 1, E. coli 2. and Klebsiella oxytoca. The average Lactococcus, Streptococcus, Mesophilic Lactobacillus / Leuconostoc and Thermophilic Lactobacillus counts were 99 ×10⁷, 96 ×10⁷, 93 ×10⁷ and 15 ×10⁷ cfu / ml. respectively. A total of 142 lactic acid bacteria (LAB) isolates were identified to the genus level as Lactobacillus (48.59%), Lactococcus (43.66%), Streptococcus (4.93%) and Leuconostoc (2.82%). Sugar fermentation tests revealed the most frequent Lactobacillus species found to be Lactobacillus delbrueckii ssp. lactis (62.32%), followed by Lactobacillus plantarum (31.88%). Furthermore, other selected LAB isolates were identified by API 50 CH test as Lactococcus lactis ssp. lactics, Lactobacillus pentosus, Lactobacillus brevis, and Leuconostoc mesenteroides ssp. cremoris. Thus, our research documented the lactic acid bacteria strains and will provides fundamental basic and useful information for further studies of strain selection starter culture, with regard to the industrial production of fermented dairy milk products.

A two-strain starter culture containing Lactobacillus plantarum CIDCA 83114, a potential probiotic strain isolated from kefir grains, and Streptococcus thermophilus CIDCA 321 was tested for the preparation of a fermented milk product. Kluyveromyces marxianus CIDCA 8154, a yeast with immunomodulatory properties was included to formulate a three-strain starter culture. Supernatants of enterohaemorragic Escherichia coli, shiga-toxin–producing strain, along with a two-strain or a three-strain starter culture were included in the medium of Vero-cell surface cultures. The results demonstrated that these combinations of microorganisms antagonize the cytopathic action of shiga toxins. The cell concentration of Lb. plantarum did not decrease during fermentation, indicating that the viability of this strain was not affected by low pH, nor did the number of viable bacteria change during 21 days of storage in either fermented products. The number of viable yeasts increases during fermentation and storage. Trained assessors analyzed the general acceptability of fresh fermented milks and considered both acceptable. The milk fermented with the two-strain starter culture was considered acceptable after two week of storage, while the product fermented with the three-strain starter culture remained acceptable for less than one week. The main changes in sensory attributes detected by the trained panel were in sour taste, milky taste and also in fermented attributes. The correlation between different sensory attributes and acceptability indicated that the panel was positively influenced by milky attributes (taste, odour, and flavour) as well as the intensity of flavour. In conclusion, the two-strain starter culture would be the more promising alternative for inclusion of that potential probiotic lactobacillus in a fermented milk product.
