Grape juice consumption has increased significantly in recent years due to the beneficial health effects showed by products derived from grape. Grape juice is the unfermented drink obtained from simple must, sulfated or concentrated, from healthy, fresh and ripe grapes. When grape juice is processed with the aim of obtaining a shelf-stable product, its product shelf-life is determined by a best-before date, which is limited due to physical and (bio) chemical reactions. With the change of these properties, the micr...

Advanced information technologies and electronics technologies lead the medical industry to a high-tech level. However, until now many tasks remain unresolved in the field of medicine and public health. The express diagnosis and the rehabilitation of the spine and musculoskeletal system is one of the actual tasks. Although there are currently diagnostic and rehabilitation systems of the spine, they are all far from perfect. This is due primarily to the lack of adequate models of areas of the nervous system and the...

The paper focuses on the results of the research study of the must and wine of the Georgian, aboriginal, rare variety of grapevine called "Khikhvi". The naturally and artificially (IR) fermented chacha was used in the experiment. The objective of artificial fermentation was to shorten the prolonged fermentation time of the freshly pressed chacha. This excludes the activation of acetic acid bacteria in the chacha under the influence of air oxygen. A rapid redox occurs in the liquid in short period by infrared irrad...

For the analysis of polyoxometalate functionality (POM), a bioassay was developed in order to determine the effect of the functionalized porous ceramic granule (with POM) on the germination of tomato plantlets (Lycopersicon esculentum) and cowpea (Vigna unguiculata). After 3 days of incubation under dark conditions at room temperature in the case of cowpea seeds and 6 days in the case of tomato seeds, the germination process was calculated and the radicle and hypocotyl growths of the obtained plantlets were biomet...

Bacillus cereus is known could cause intestinal diseases as typical sporogenous contaminant of foods. On the other hand, probiotics form a number of factors to inhibit bacilli growth, e.g. short-chain fatty acids. The patterns of Bacillus cereus ATCC 11778 bacilli specific growth rate reduction by metabolites of bifidobacteria (both in pure substances and when produced in mixed culture) were applied for the model development. These regularities were supposed to be appropriate for prebiotic activity assessment in v...

The present study was conducted in order to investigate the effect of various organic food acids, on the proteolytic processes taking place in chicken. A poorly acidic medium favors the process of tenderizers the meat, this being a chemical method of accelerating proteolysis. Citric acid from lemon juice, lactic acid derived from yoghurt and borscht, acetic acid of natural fermentation have been used for this purpose. Meat samples were marinated in these media for 3 days, being preserved at the refrigeration tempe...

It is necessary to determine the amount of starch in order to find effective methods of controlling it in technological flows of paper mills. Enzymatic methods for starch determination based on the selective action of amylolytic enzymes on starch are promising. Water-soluble low molecular weight dextrins are formed when starch is treated with alpha-amylase. Dextrins are then hydrolyzed by glucoamylase to glucose, which is determined by various methods. Material pre-treatment is necessary to increase starch availab...

Fruit yogurts are always preferred among dairy products, as they are delicious low-calorie foods associated with healthy nutrition. Now yogurts with tropical fruits are popularity due to their exotic taste and positive influence on human health. The production of yogurt with the addition of feijoa is limited to a short period of storage and selling of this fruit. Vacuum freeze-drying can solved this problem. Therefore, the aim of this research was to determine the rational amount of freeze-dried feijoa for adding ...

Previously it was believed that stress influence on microorganisms is only negative, reducing the efficiency of biosynthesis. However, it has been shown now that with the use of controlled stress, it is possible to increase the efficiency of microbial cultivation processes. Among other types of stress, oxidative stress is the most significant. When microorganisms are exposed to oxidative stress agents, breaks can occur in nucleic acid molecules as well as of protein molecules, in addition to this, the blockage of ...

The bioconversion of plant raw materials into highly added value products, as well as the development of new products with advanced characteristics has a high priority for modern biotechnology in the Russian Federation. Deproteinized sunflower meal has been used as a source of carbohydrates and organic nitrogen for the yeast S. cerevisiae fermentation after subsequent acidic and enzymatic treatment. As a result a protein-rich yeast biomass was formed, as well as a liquid fraction, containing non-metabolized pentos...
