Adsorptive purification of ether-aldehyde fraction by natural adsorbents
(2013) Melnyk (Tkachuk), Nataliia; Melnyk, Zinoviy; Shevchenko, Oleksandr
The authors proposed an effective method of processing EAF by using cheap local adsorbents: palygorskite and hydromica, which have high adsorptive properties, could be re-generated and recycled, and deposits of which are developed in Ukraine.
Methods of recovering schungite’s adsorptive properties after processing red beet juice
(2013) Melnyk, Lyudmila; Melnyk, Zinoviy; Krivorotko, Volodimir
Shungita investigated regeneration techniques for reuse in the production technology of red beet juice. The expediency of using the method of regeneration shungita superheated steam certain parameters.
Physico-chemical and organkleptic properties of red beet juice purified by shungite
(2013) Melnyk, Lyudmila; Krivorotko, Volodimir; Melnyk, Zinoviy
Fresh 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.
Recovering adsorptive properties of schungite after processing red beet juice
(2013) Melnyk, Lyudmila; Melnyk, Zinoviy
When 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.
Researching antiseptic properties of shungite when producing red beet juice
(2012) Melnyk, Lyudmila; Melnyk (Tkachuk), Nataliia; Melnyk, Zinoviy
Іnvestigated antiseptic properties Shung in the production of table beet juice. The efficiency of absorption of harmful microorganisms from juice Shung.
Water-alcohol adsorbing cleaning out of higher alcohols by shungite
(2014) Melnyk, Lyudmila; Turchun, Oleg; Melnyk (Tkachuk), Nataliia; Kuts, Anatoly; Melnyk, Zinoviy
The aim of the research work is to increase the quality and safety of high spirits solutions at the expense of using natural adsorbent shungite.
