Документ Recovering adsorptive properties of schungite after processing red beet juice(2013) Melnyk, Lyudmila; Melnyk, ZinoviyWhen producing food dye from red beet juice part of impurities, especially pectin substances, is adsorbed by the carbon adsorbent - shungite, containing fullerenes and fullerene nanotubes. During adsorption of red beet juice, surface and pores of shungite are filled with impurities, resulting in decrease of its adsorptive properties.The purpose of the present studies was to select an effective method for regeneration of adsorbent and to establish rational technological parameters of this process.When choosing a method of regeneration, the authors of this paper were motivated by economic feasibility and took into account the availability of necessary equipment at canning factories.Документ Improving the technology of producing food grade dye from red beet juice(2012) Melnyk, Lyudmila; Sheiko, Tamila; Stroy, A.Red beet juice is very useful food product, because it contains significant amount of sugars, mineral substances and vitamins. It is also valuable because it is used for producing food grade dye. Nowadays in order to give to food products a color, close to natural coloring of fruits and vegetables, expensive synthetic dyes are used, which might have cancer-inducing effect when being accumulated by human organism. The refore improving the technology for producing food grade dye from red beet juice is remarkably important task. Currently for the purpose of obtaining dye from red beet juice, a part of pectin substances,which make the process of juice concentration more difficult, is removed with the help of expensive enzymatic agents. The authors have suggested using natural carbon-bearing adsorbent shungite to purify red beet juice from pectin substances.Документ Utilization of shungite forimproving quality and safety of juices(2010) Melnyk, Lyudmila; Sheiko, TamilaFound that shungite has effective adsorption properties relative to nitrate ions from beet juice. Shungit also absorbs ammonium ions in drinking water. An illustration of the mechanism of adsorption processes in the "solid - liquid".
