Abstract

Hypochlorous acid(HOCl) is a chemical that is a safe sanitizer and disinfectant approved by the Food and Drug Administration as a food additive, exhibiting strong sterilizing power with low effective chlorine concentration of pH 5.0-6.5 and effective chlorine concentration 10-80 ppm. To apply to fishery industries, we develope the HOCl ice for store or delivery of fishery products. However when HOCl is being frozen, the contained HOCl are expelled out from the ice due to the molecular structures of ice; there is no space to contain HOCl inside. To increase chlorine containing amount in ice, we develop the alginate particles containing HOCl which is bio comparable since alginate is a natural polymer extracted from the brown algae and it is widely used for drug delivery and containing substances, etc. We produce HOCl with water as base solution suppressing osmotic flow from fishery products, and mix it with the developed alginate particles and made HOCl-alginate ice and checked the remaining amount of HOCl. We measure the change of pH and chlorine concentration optimizing the best concentration of alginate particles. Finally, we produce the alginate particle HOCl ices with respect to the alginate's optimal concentration.
