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 Physico-chemical and organkleptic properties of red beet juice purified by shungite(2013) Melnyk, Lyudmila; Krivorotko, Volodimir; Melnyk, ZinoviyFresh red beet juice contains substances which coulddeteriorate its quality. Therefore, juice should be purifiedfirst. The promising method of purifying red beetjuice from unwanted impurities is using carbon-bearingadsorbent - shungite, uniqueness of which can beexplained by existence of fullerenes and nanotubes.The aim of this paper is to study how physico-chemicaland organoleptic properties of red beet juice changewhen processed by shungite. Проведено дослідження по відновленню адсорбційних властивостей природного мінерала шунгіта, який використано для очищення соку столового буряка від пектинових речовин при виробництві харчового барвника. Запропоновано два методи регенерації шунгіта із урахуванням економічної доцільності та наявності необхідного обладнання на консервних заводах. Встановлено раціональні параметри регенерації шунгіта.Документ Researching of microbiological parameters of apple juice, processed by shungite(2013) Melnyk, Lyudmila; Matko, Svetlana; Shevchenko, OleksandrWhen processing apple juice by shungite, simultaneously with the adsorption of harmful microorganisms,colloidal substances are also adsorbed, and that in turn promotes clarification of juice.This work proves the expediency of adsorptive processing of apple juice by shungite with fraction of 1 ... 3mm. Rational parameters of apple juice processing, under which the maximum reduction of microbial insemination is reached, are the following: shungite concentration of -1.5 ... 2% mass., temperature - 60°C,duration - 60 min.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 Adsorption of ammonia nitrogen from water and of nitrate ions from vegetable juices by shungite(2011) 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".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".
