Researching of microbiological parameters of apple juice, processed by shungite
(2013) Melnyk, Lyudmila; Matko, Svetlana; Shevchenko, Oleksandr
When 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.
Adsorption of ammonia nitrogen from water and of nitrate ions from vegetable juices by shungite
(2011) Melnyk, Lyudmila; Sheiko, Tamila
Found 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".
