Документ Studying the process of extracting sugary substances from the stalks of sweet sorghum in the technology of making food syrups(2021) Gusyatinska, Natalia; Hryhorenko, Nataliia; Kalenyk, Olha; Gusyatinskiy, Nikolai; Teterina, SvitlanaThe 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.Документ Research into application of zeolite for purification of diffusion juice in sugar production(2018) Gusyatinska, Natalia; Nechypor, Tatiana; Gusyatinskiy, Nikolai; Shulga (Zamura), SvеtlanaThe need to intensify the extraction process using the influence of chemical reagents on beet chips was substantiated. The analysis of application of natural sorbents in food production technologies was carried out. The physical and chemical properties of zeolite were explored. The indicators that make it possible to apply natural zeolite for additional treatment of water and juices in sugar production were shown. The effectiveness of the use of natural zeolite for feed water treatment with the view to enhancing the technological quality of diffusive juice was determined. Experimental research revealed that feed water treatment with zeolite decreases the content of total iron, ammonium, and permanganate oxidation indicator. It was proved that microbial seeding of feed water and diffusive juice decreases in case of treatment with zeolite.It was established experimentally that the purification of diffusion juice occurs during zeolite application for feed water treatment. We determined the effectiveness of removal of macromolecular compounds, including dextran, from diffusive juice obtained during processing sugar beets of various technological quality with natural zeolite. It was shown that at the zeolite consumption of 0,1...0,4 % to the weight of beets, the content of high-molecular compounds and pectic substances in diffusive juice decreases by 30–40 %, and the content of dextran – by 20–40 %, respectively.During the zeolite treatment, an enhancement of the quality of purified juice and im-provement of filtration and saturation properties of defecosaturated precipitate are observed. Thus, the average rate of sedimentation of the precipitate of juice of І carbonation S5 m, when using zeolite for feed water preparation increases by 10–50 % for the beet different technological quality. In the course of research, we designed the technique of zeolite application, which ensures a decrease in coloration, an increase in the purity of the cleared juice, enhancement of filtration and sedimentation properties of the precipitate of juice of I carbonation. High effectiveness of the proposed method is pronounced in processing raw materials of lowered quality. Thus, there are some grounds to claim the effectiveness of zeolite application to enhance the quality of diffusion juice and products in sugar production.
