Документ Дослідження процесів ферментації для стабілізації стійкості пива(2023) Романова, Зоряна Миколаївна; Карпутіна, Маргарита Віталіївна; Олійник, Світлана ІванівнаОдним із основних споживчих показників готового пива є його стійкість. Під час зберігання пива з часом у ньому відбуваються окисні процеси. Завдяки кисню, який вступає в хімічні реакції з жирними кислотами, вітамінами, амінокислотами та ароматичними речовинами, утворюються сполуки, що змінюють колір, смак і фізико-хімічні показники. Одночасно з фізико-хімічними процесами, що відбуваються під час зберігання пива, можуть протікати і мікробіологічні процеси, які сприяють мікробіологічному забрудненню готового пива.Документ Physical, chemical and organoleptic characteristics of low alcohol beverages basedon sugar sorghum(2019) Karputina, Margarita; Khargeliia (Karputina), Daria; Melnyk, IrynaThe paper evaluates the modern market of soft drinks. The production of soft drinks is characterized by an extremely wide variety of raw materials. The use of juices, concentrates, infusions and extracts of plant raw materials, flavors, emulsions, aromatic bases, food acids, vitamins, dyes, stabilizers, preservatives, brighteners, turbidizers, sweeteners and other raw materials and materials that meet the requirements of applicable regulations and have permission Ministry of Health. It is established that the increase in demand for these beverages will be with the use in the technology of natural plant materials, which are biologically active substances. Sugar sorghum is offered as a high-quality raw material, which is a promising crop and is characterized by a rich component composition. It is proposed to obtain weak drinks by fermenting the wort on the basis of sugar sorghum juice with the addition of apple and apple-cherry concentrates. Physico-chemical parameters of the wort are determined and the modes of its fermentation by dry yeast of the manufacturer "Biowin" - Brewgo-01 and the manufacturer "Fermivin" - Gervin GV1 are proposed, which are considered for brewing and wine dilutions, respectively. The influence of these placers on the accumulation of potential food products and the formation of organoleptic characteristics of beverages has been studied. It was found that in the studied samples of the best products are in quantities close to the threshold of sensation and, of course, affect the taste and aroma profile of finished drinks. Profilograms of taste and aroma and the made product about prospects of use of salted sorghum in technologies of low-alcoholic drinks on the basis of natural raw materials are constructed.Документ Methods of determination of parameters of fermented whey-malty mixtures(2018) Tsygankov, Sergii; Ushkarenko, Viktor; Grek, Olena; Krasulya, Olena; Ushkarenko, Iuliia; Tymchuk, Alla; Onopriichuk, Olena; Savchenko, AlexanderThe methods of accumulation of yeast cells Kluyveromyces lactis 469 and their percent with glycogen from the general concentration at fermentation of wort of the restored mixture at different ratios of dry malt and whey are offered and results are obtained. According to the obtained data, it was established, that yeast cells actively developed in the period from 4 to 16 fermentation hour at the ratio of malt and whey in the restored mixture as 1:1,5 and 1:2. The increment of cells with glycogen in mixtures with the ratio – malt:whey as 1,5:1 and 2:1 was intensive. Thus, at 36 hour of fermentation the amount of yeast was 67,2 and 68,9 % respectively from the total number of cells.Документ Identification of by-products of fermentation of whey and malt worts(2013) Chepel, Natalia; Grek, Olena; Krasulya, OlenaResults of gas chromatographic studies for definition of by-products of fermentation of whey and malt worts enabled evaluate advantages Zygosaccharomyces lactis 868-K yeast race objectively. Presence of the given yeast race in nutritional medium has a positive effect on producer’s metabolism, thus stimulating biosynthesis or transformation of nutritional medium aromatic substances.
