 Expanding the assortment of sour cream with increased nutritional value is an actual direction of scientific research. The purpose of the work is the scientific explanation of heating process duration based on the analysis of its influence on the sensory and physicochemical indicators of cream, enriched with milk protein concentrates as a basis for the production of baked sour cream. The regularities of changes in the quality indicators of cream (10–20 % fat), enriched with 1 % of concentrate of whey proteins (94 % total solids) and with 30 % of liquid concentrate of hydrolyzed whey (40 % total solids) under the influence of heat treatment at a temperature of 96±1 ⁰С for 15 to 120 minutes were determined. Due to the introduction of whey protein concentrate into the composition of cream, the protein content increases by 0.77 %, and in samples with liquid hydrolyzed whey concentrate by 0.42 %. Liquid hydrolyzed whey concentrate also increases the solid content in cream by 9.36–9.37 % while simultaneously reducing the lactose content by 6.2–6.7 times, which is promising for the production of low-lactose sour cream. Whey protein concentrate more effectively reduces surface tension, exhibits a higher stabilizing and structuring ability, compared to liquid hydrolyzed whey concentrate. Instead, the concentrate of liquid hydrolyzed whey with a high content of monosaccharides activates the Maillard reaction with the formation of an intense cream color, gives the cream a pronounced sweet taste and baked aroma. Both concentrates significantly improve the sensory properties of cream, which makes it possible to recommend them for use in baked sour cream technology. Based on the results of a comprehensive analysis of the quality indicators of baked cream samples with a fat content of 10–20 %, it was concluded that heat treatment of cream with liquid hydrolyzed whey concentrate and cream with whey protein concentrate should be carried for 15 minutes and 30 minutes, respectively, which will allow purposeful regulation of energy consumption in the technology of baked sour cream with increased protein content.

Using FTIR spectroscopy, it was found that the pyramids of the bags are made of thermoplastic polymers polyethylene terephthalate (samples 1-7) and polylactic acid (sample 8). The threads attached to the pyramids are made of thermoplastic polymers polypropylene (samples 1,2,4-7), polyethylene terephthalate (sample 4) and polylactic acid (sample 8). The specific optical rotation of polylactic acid [α]D25 is about -150° (c=1, CHCl3), which refers to poly(L-lactic acid). Using optical microscopy, it was established that the structure of the pyramids are divided into those made of plain woven fabrics (samples 1-3) and heat-bonded nonwoven fabrics (samples 4-8). The tea bags (samples 1-3) exhibit a well patterned net structure (mesh) with the pores perceived to be uniform and regular. The tea bags made of nonwoven materials have an irregular network consisting of compact and random arrangement of fibers. The fibers are pleated randomly, generating irregular pores. Nonwoven fabrics are made from fibers with a diameter of 12-18 µm, woven fabrics are made from fibers with a diameter of 48-54 µm. The area density of nonwoven fabrics is 18.5-20.3 g/m2, the area density of woven fabrics is 22.0-22.7 g/m2. The threads are made by twisting several single-twisted yarns. The structure of threads are a cabled yarn from three 2-ply yarns (samples 1,8), 4-ply yarn (samples 2-4,6,7) and 4-ply multyfilament yarn (samples 5). The final twist of the plied yarn/cord is S-twist. The primary structural element of threads in the case of samples 1-4, 6-8 are staple fibers, of sample 5 are multyfilament fibers.

Monographic, constructive, causal analysis and logical generalization methods were used. Cheese is the most popular food product in the world; there are 5,000 varieties of cheese. Although standard cheeses produced on large-scale productions are the most popular and widespread, authentic cheeses are also popular due to their unique organoleptic properties. Many factors influence the unique characteristics of authentic cheeses, the main of which are the quality of milk, its microbiological and chemical composition, and the technological methods used in cheese-making. All authentic cheeses are characterized by the presence of lactic acid bacteria, but the use of untreated milk sometimes leads to the presence of foodborne pathogens in the final product. Certain authentic cheeses have a complex microbiota, which complicates their production and the creation of starter cultures. However, for many cheeses, especially those like feta, there are now technological approaches to production, and most research is aimed at achieving an authentic taste and improving the organoleptic properties of the final product. Analysis of the quantitative and qualitative composition of the fermenting microbiota and the technological features of different types of traditional cheeses makes it possible to determine the composition of new fermenting compositions that are inherent to a particular product and to choose ways to increase the efficiency of cheese production.","PeriodicalId":41845,"journal":{"name":"Journal of Food Science and Technology-Ukraine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136134637","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Accordingly, humans are omnivores, while domestic animals are divided into ruminants, monogastric herbivores, and monogastric omnivores, and birds are divided into herbivores (geese, ducks) and omnivores (chickens, turkeys, etc.). The digestion and assimilation of food and feed depends not only on own mechanisms but also on the GIT microbiome. The location of the most important part of this microbiome and its composition depend on the species: in ruminants, it is the rumen microbiome, in horses – the cecum (it is a counterpart of the rumen), in humans and pigs – the intestine, in birds – the crop, gizzard and cecum. These microbiomes are in constant close connection with the host organism, and this connection is realized through numerous molecular mechanisms of interaction between bacterial cells and host cells and tissues. GIT microorganisms not only help to assimilate food (feed) by partially digesting it, but also secrete biologically active substances that have protective, stimulating and other beneficial effects for the host. In adult hosts, this GIT microbiota is well developed and stable, while in children and young animals it can be much more mobile and vulnerable. Food and feed contain many components that are a favorable medium for the development of microorganisms. Raw materials and components of animal origin are the most contaminated, while vegetable raw materials and components, as well as premixes, contain significantly fewer microorganisms. Among the microorganisms colonizing raw materials, food and feeds, coliforms, salmonellae and molds may be present. In young animals, the feed microbiota ingested into the GIT, even without taking into account obligate or opportunistic pathogens, can cause shifts or changes in the digestive microenvironment towards deterioration, which will have a corresponding impact on the efficiency of feed absorption and, through it, on the efficiency of feeding and animal productivity.","PeriodicalId":41845,"journal":{"name":"Journal of Food Science and Technology-Ukraine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136232087","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among them is a group of polysaccharides such as mannans. Mannans are polysaccharides composed of D-mannose residues as the main chain. They possess a number of properties: immunomodulatory, cancer-protective, antimicrobial, and normalize blood cholesterol levels. Mannans are present in a number of plants, algae and microorganisms. One of the promising sources of mannans can be coffee sludge, which is accumulated on an industrial scale at instant coffee companies. This article describes a biotechnological method for the production of water-soluble mannan from coffee sludge and investigates the possibility of increasing the yield of water-soluble low-molecular-weight mannan with the maximum content of physiologically active fractions by pretreating the raw material with ultrasound and ultrahigh-frequency radiation. The sludge was pretreated in an aqueous medium using ultrasound at 25, 35 and 40 kHz for 15 minutes and treatment in a 2.45 GHz ultra-high-frequency electric field with a power of 300 W, 600 W and 800 W for 5 minutes. Next, the physical disintegrate was treated with an enzyme preparation with beta-mannanase activity and centrifuged. The resulting water-soluble products were characterized by gel chromatography to determine the molecular weight distribution of the fractions of each sample. It was found that the pretreatment with ultrasound is expedient, since the total amount of fractions with a molecular weight of less than 20 kDa is almost 80%. The treatment of raw materials with microwave rays is inefficient and leads to an increase in fractions of molecular weight less than 1 kDa. Thus, varying the conditions of the preliminary physical treatment of coffee sludge allows to regulate the molecular weight distribution of water-soluble enzymolysis products and obtain products with the required range of molecular weight values.","PeriodicalId":41845,"journal":{"name":"Journal of Food Science and Technology-Ukraine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136231946","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The solution to the problem is possible through changes in the structure of nutrition, and above all, through an increase in the diet of vegetables and fruits of high quality, the varieties of which have been created using biofortification strategies. Biofortification is an innovative and promising approach in solving global problems related to nutrition. The goal of biofortification is to create plants with increased levels of the necessary functional ingredients absorbed from the soil, as well as those synthesized in the plant. Biofortification strategies consist in the development of optimal ways of mineral nutrition of plants, the creation of new species using molecular genetic approaches, and the use of traditional breeding methods. The purpose of the research is to analyze the modern experience of creating varieties of various fruit and vegetable crops with the help of biofortification strategies, which have an increased content of functional ingredients. Based on the literature review, it was established that for many years, an unconventional direction of selection has been developing – the creation of varieties and hybrids of fruits and vegetables with the recommended chemical composition.

It is emphasized that in order to create scientific foundations and practical directions for the use of new raw materials in the production of flour products, comprehensive studies are needed to study its composition, physical and chemical properties, as well as the impact on the quality of finished products. The amino acid composition of the proteins of these meals and wheat flour was experimentally determined. Calculated amino acid score. Particular attention is paid to the mathematical calculation of the composition of oilseed meal, which, in terms of amino acid composition, is as close as possible to the reference protein. The mass fractions of soybean, flaxseed and sunflower meal proteins in the composition were determined, namely: 0.51, 0.2 and 0.29, respectively. The amino acid composition and the biological value of the protein of the obtained meal composition were established. It was shown that for such amino acids as lysine, the amount of sulphurous (methionine + cystine) and threonine amino acid score of combined flour systems increased by 0.7–2 times compared to that of wheat flour. The ratio of soybean, linseed and sunflower meal in the composition of the improved amino acid composition in percentage terms was obtained: 44:25:31. Mathematically calculated the content and rate of essential amino acids in systems, which in their composition contain 90–80% wheat flour and 10–20% composition of oilseed meal.

Over the past few decades, the demand for products that have a positive impact on human health has exploded worldwide. The market for functional foods in developed countries is estimated at USD 300 billion, which makes this sector attractive for investment. Accordingly, the production of functional foods and ingredients needs to be regulated at the state level. There is no harmonization in the definitions of functional foods and their classification at both the global and state levels. Despite the fact that the concept and terminology of functional food and the means of achieving it is well-established, the term “functional food” is often absent in the legislative acts of countries that actively produce functional foods, and the term “health-related food” is used instead. As a rule, health-related foods are subject to quality and safety requirements that are identical to those of conventional food products. Exceptions are regulations that establish rules for labeling FFPs and statements regarding their physiological effects or the content of a particular ingredient that may affect physiological aspects. In Europe and the USA, much attention is paid to the safety of “health-related food” and the novel food products. European Food Safety Authority and the US Food and Drug Administration require sponsors to submit information on the composition of multiple batches of a product to support safety evaluations for novel foods and Generally Recognized as Safe (GRAS) ingredients. In Ukraine, the legal status of the terms “functional food product” and dietary supplement was regulated by Law of Ukraine 771 “On Basic Principles and Requirements for Food Safety and Quality”, but in the version of this law dated 16.01.2020, this term was excluded, the term “dietary supplement” was edited and the term “novel food product or ingredient” was included, which is related to the process of harmonization of Ukrainian and European legislation in the food sector.

In Ukraine, hops are basically processed into Type 90 pellets, that are practically indistinguishable in terms of biochemical indicators from hop cones. Pellets of hop are the single domestic source of hop products that can be serve as an alternative to imported pellets and extracts that used in the Ukraine brewing. Comprehensive studies of the evaluation of Type 90 hop pellets of aromatic and bitter varieties produced in Ukraine and European countries allowed establishing that they have different biochemical compositions and consequently, different brewing value. That have been identified differences in the absolute values of indicators such as the mass fraction of alpha acids, beta acids and their composition, xanthohumol, essential oil, the ratio of valuable hop compounds: beta acids to alpha acids and components of the essential oil. It has been determined that in hop pellets of aromatic varieties, the content of alpha acids changing from 3.3% in the Klone 18 variety to 5.9% in the Hallertauer Tradition variety. The content of beta acids, in the investigated pellets, ranges from 3.6% (Klone 18) to 6.7% in the Slavyanka variety. It is established that the hop pellets made from Ukrainian varieties Zagrava and Slavyanka have significantly higher content of beta acid 6.3% and 6.7%, respectively, compared to pellets of foreign varieties. There is a significant advantage in the resin fraction of beta acids over the fraction of alpha acids in the pellets of Slavyanka, Klone 18, Zhatetsky and Zagrava varieties, that they meaning retain a positive coefficient of aromaticity between the content of beta and alpha acids that ranges from 1.18 to 1.37. The content of alpha acids ranges from 8.7% in the Polisky variety to 14.1% in the Magnum variety in the hop pellets of bitter varieties. The content of beta acids in the same pellets ranges from 4.2% to 5.9%. It has been established that the composition of alpha and beta acids in the investigated pellets changes depending on the variety. It has been proven that Ukrainian-produced hop pellets correspond to their international counterparts in terms of their characteristics. Specifically, the biochemical and technological indicators of Klone 18 hop pellets correspond to the characteristics of pellets of the Czech variety Zhatetsky, pellets made from the bitter variety Alta correspond to the biochemical indicators of German Magnum pellets but pellets of varieties such as Slavyanka and Zagrava exceed the world analogies in terms of the composition and quality of bitter substances and essential oil. Based on the comparative biochemical characteristics of Type 90 hop pellets of Ukrainian and European production, the quality of Ukrainian hop products has been found to be at a global level. Certified domestic hop products, specifically Type 90 pellets, can be used do not only by Ukrainian brewers but also by other manufacturers to create new innovative and competitive products with various functional purposes.","PeriodicalId":41845,"journal":{"name":"Journal of Food Science and Technology-Ukraine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135369911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
