(2021) Gusyatinska, Natalia; Teterina, Svitlana; Hryhorenko, Nataliia; Kalenyk, Olha
This article presents the relevance of the issue of inhibition of microbiological processes at different stages of processing of sugar-containing raw materials, in particular ensuring the microbiological purity of juices and syrups in the production of sugar sub-stances. Information on the composition of microbiota contaminating raw materials in the production of beet sugar, raw cane sugar, food syrups from sugar sorghum is analyzed.Experimental data on the evaluation of the effectiveness of a number of antimicrobial preparations in terms of growth retar-dation of pure cultures of microorganisms and the effect of disinfection during the introduction of preparations are presented.The greatest danger in production is caused by the development of spore-forming and mucus-forming bacteria, which led to the choice of research objects.Thus, the effect of antimicrobial preparations on microorganisms: mesophilic bacteria Bacillus subtilis,B. megatherium,thermophilic bacteria B. stearothermophilus, mucus-forming bacteria of the genus Leuconostos, was investigated. In addition, the effect of antimicrobials on mycelial fungi of the genus Aspergillus was studied.Based on the conducted experimental studies, the range of costs of the studied antimicrobial preparation for the suppression of contaminating microf lora in the production of sugar and food syrups from vegetable raw materials was determined.

The need to intensify the process of extracting sugar substances from sweet sorghum stalks in order to improve the quality and yield of the target product has been substantiated. Existing techniques of sugar substance extraction used in sweet sorghum processing technologies have been analyzed. The application of a combined technique for extracting sugary substances has been proposed implying the production of pressed and diffusion juice.The results of optimizing the press technique of juice extraction from sorghum stalks are given. The equations of material balance of products and sugars have been built, depending on such factors as the degree of pressing, the initial content of solids and sugars in the stalks. A procedure for calculating the yield of pressed juice, cake, and the content of total sugars has been devised, according to which the preliminary pressing of the stalks ensures the extraction of juice in the range of 25‒35 %, the yield of the pressed cake is 75‒65 % on average, with a sugar content exceeding 60 %.It has been experimentally established that the use of the anti-current process of extraction of sugar substances from the pressed cake ensures their complete extraction from raw materials.The rational parameters for this process have been defined. At a temperature of 66–70 °C and a duration of 20 minutes, it is possible to obtain an extract whose content of solids is 13.0 %, total sugars ‒ 11.10 %, and whose purity is 85.38 %. The research was carried out in order to ntensify the extraction of sugar substances from sweet sorghum plant raw materials, to improve the technical level of the extraction process, and implement the devised method under industrial conditions. Further implementation of these results in the food industry could make it possible to establish the production of a wide range of sugar-containing products, both organically and as a natural substitute for sugar in food products.
Determination of the disinfectants efficiency on microorganisms - active gray rot causative agents within the process of sugar beet storage
(2015) Gusyatinska, Natalia; Teterina, Svitlana; Nechypor, Tatiana; Kasian, Irina
The article presents the results of research on the effectiveness of modern disinfectants on the basis of sodium salts of dichlorosaccharide, polyhexamethylene guanidine, citroside, monensin sodium and natural hydroxy acids in relation to the contaminating microflora of sugar beets.
Study of antimicrobial characteristics of spices composition
(2015) Teterina, Svitlana; Yushchenko (Gonchar), Natalia; Bandura (Kuzmyk), Uliana; Khlystun, Irina
In order to produce safe, high-quality milk and cultured milk foods with a prolonged storage period it is important to inhibit the development of microorganisms. The research aims to study the effects of previously developed spice aromatic composition on test cultures of microorganisms (samples of contaminating microflora), such as Enterobactercloaceae, Micrococcus albus, Bacillus subtilis, Endomyceslactis. The spice composition contains ginger, cinnamon, cloves, curcuma, sumac, anise, black pepper and sweet pepper, cardamom, fenugreek, nutmeg and badiane (star anise).
Determination of microbiological and physicochemical characteristics of sweet sorghum and wort on its base in the non-alcoholic drinks technology
(2014) Korolenko, A.; Karputina, Margarita; Khargeliia (Karputina), Daria; Teterina, Svitlana
The paper identified the quantitative and qualitative composition of microflora and basic physical and chemical properties of sugarsorghum juice, diluted apple concentrate and mash on them. The samples wort for physico-chemical parameters recommended for use intechnology fermented soft drinks.The use of technology fermented beverages mash of soft thermal processingof sorghum juice and sugar mixture 70% nepidkyslenoho and unpasteurized juice mash of sorghum and sugar 30% diluted apple cider for quality and safe products.
