Документ Influence of starch products on the vitality and activity of lactic acid bacteria in yogurt(2024) Ivashchenko, Olga; Khonkiv, Myroslav; Stabnikov, Victor; Polishchuk, Galyna; Marynin, Andriy; Buniowska-Olejnik, MagdalenaThe influence of starch product with different dextrose equivalents addition on the viability and activity of lactic acid bacteria Streptococcus thermophilus and Lactobacillus delbrueckii ssp. bulgaricus during fermentation and storage of yogurt has been studied. An increase of dextrose equivalent and monosaccharides content in starch products reduce the fermentation time of milk due to the increase of lactic acid bacteria activity. A slight decrease in water activity in the presence of glucose-fructose syrup in yogurt in an amount of 9% had virtually no effect on the milk fermentation process. The number of lactic acid bacteria increased during the first seven days of yogurt storage added with glucose-fructose syrup. On the 14th day of storage, the concentration of cells of S. thermophilus and L. delbrueckii ssp. bulgaricus became almost the same in all yogurts due to almost complete consumption of carbon sources. When the storage of yogurt was extended to 28 days, the most stable content of lactic acid bacteria was found in yogurt added with maltodextrin due to its prebiotic properties. The increases of active acidity and syneresis in all yogurts were greatest in the first 8–14 days. Presence of dextrins in yogurt stabilizes its physical and chemical properties during storageДокумент Utilization of plant processing wastes for enrichment of bakery and confectionery products(2023) Stabnikova, Elena; Shevchenko, Anastasiia; Stabnikov, Victor; Paredes-López, OktavioIn this mini-review some technologies proposed by Ukrainian scientists for utilization of plant processing waste to enrich bakery and confectionery products are present. Partial replacement of wheat flour with plant additives allowed to increase nutritional value of food products. Thus, replacement of wheat flour with 5–20% of pumpkin seed flour resulted in an increase of protein content by 13.9–55.5% and fiber content by 12.07–48.7% in bread in comparison with control one without additives. Replacement of wheat flour, 5–15%, with pumpkin cellulose increased the content of protein 1.1–1.4 times and dietary fiber in 1.4–2.2 times in comparison with control bread. Bread supplemented with oat bran, 5–15% instead of wheat flour had higher by 19.5–52.2% score of lysine than bread without plant additives. Waste from grape processing containing protein, lipids, fiber, minerals and polyphenols, could be successfully used in preparation of flourbased confectionery products. Grape seed powder could serve as a substitute of cocoa powder in confectionery coatings technologies. Grape seed cake powder and grape skin powder being used for partial replacement of wheat flour in biscuits enriched the product with dietary fiber, polyphenolic compounds, minerals and vitamins. Addition of flour from extruded sunflower seed kernels in preparation of gingerbread allows to enrich it with valuable nutrients and improve its technological characteristics. Wastes from the processing of plant materials contain valuable substances and can be used in the preparation of functional products. It is essential to maintain and preferentially increase the high quality of products; thus, it is necessary to replace wheat flour with a plant additive in amounts not exceeding 10%.
