The Use of Electrolytic Hydrogen Bubbles for New Method of Juice Concentration
Abstract: Currently, juice concentrates are produced by separating water from fresh juice. For the production of juice concentrates, one of the following methods is used: evaporation of freezing water or the diaphragm method. During evaporation, the juice is heated in a vacuum in special trays, but this heat is not brought to the boiling point, since during the boiling process all useful substances will be destroyed. The mass obtained after evaporation …

Application of Aqueous Two-Phase Systems in the Extraction of Bovine Serum Albumin
Abstract: Protein partitioning in an aqueous two-phase system (ATPS) has been found to be a powerful method for extracting and separating mixtures of biomolecules. In ATPS, many factors influence the partition coefficient K (which is the ratio of protein concentration in the top phase to that in the bottom phase) and the recovery percent (Rec%). Two systems of ATPS were used: first, polyethylene glycol (PEG4000)/sodium phosphate, and second, PEG4000/dextran. The behavior …

Sources, Levels and Carcinogenic Potential of Polyaromatic Hydrocarbons in the Environment: A Short Review
Abstract: Polyaromatic hydrocarbons (PAHs) are the organic compounds that constitute a class of aromatic hydrocarbons known to be cancer causing agents. In the recent years an increased attention towards their sources and levels in the environments has been observed, mainly because of the elevated levels of some highly carcinogenic or mutagenic PAHs. The US Environmental Protection Agency (EPA) has recognized 16 PAHs (EPA-PAH) as priority pollutants. Eight from these 16 PAHs …

Formation of Anolyte and Catholyte Types of Water during electrolysis and their Effect on Living Organisms
Abstract: During electrolysis, an anolyte (dead water) and catholyte (living water) solutions are formed. Anolyte promotes metabolic processes, and is also mild antiseptic. The disinfecting effect of the anolyte is equivalent to treatment with iodine, brilliant green, hydrogen peroxide, without causing chemical burns of living tissues and not staining them. The living water, being a catholyte, has enhanced bio stimulating properties. It has a beneficial effect on the human organism, enhancing …
