Abstract:
The purpose of the present invention lies on providing a natural food preservative including chitosan, which is excellently dissolved, as active ingredient. The present invention includes following steps of: producing chitosans of multiple forms by differentiating the time and temperatures of reactions between insoluble chitosan and caustic soda; obtaining time-differentiated enzymatic reactants by applying chitosanase into each chitosan produced earlier; obtaining chitosan with excellent antibiotic properties by evaluating each enzymatic reactant obtained earlier; obtaining a mixture by mixing the chitosan obtained earlier with grapefruit seed extract, citric acid, cinnamon spirits extract and dextrin; and lyophilizing the mixture. [Reference numerals] (AA) Sorbic acid 300 ppm; (BB) Freezing 0.5%; (CC) Freezing 1.0%; (DD) Viable cell; (EE) Storage time (day)
Abstract:
PURPOSE: A natural germicide containing chitosan and antibacterial tissues treated with the same are provided to reduce the irritant about the skin by using the chitosan. CONSTITUTION: Chitosan 0.1~2.0 weight% and the extract of grapefruit seed 0.001~0.1 weight% are added to the solution of the neutral spirits 15~37 weight%. The chitosan is used for manufacturing of natural sanitizers and disinfectants. After the chitosan is dissolved in citric acid solution, the chitosan is added in the appropriate concentration. If a tissue fabric is processed with the nature sanitizers and disinfectants, a chitosan contained antibacterial tissue is manufactured. A span lace 50 is used as a tissue cloth.
Abstract:
PURPOSE: A Kimchi using water and chitosan powder for pickling is provided to make Kimchi containing chitosan high antibacterial activity, antioxidative activity and anti-mutation effect. CONSTITUTION: A chitosan powder for pickling with antibacterial, antioxidative and anti-mutation and anticancer activities contains water soluble chitosan having 50-90% of deacetylation and 1-10cP viscosity, insoluble chitosan having 60-100% of deacetylation and 8-80cP of viscosity and its pharmaceutically acceptable salt. The sitologically acceptable salt is hydrochloride, acetate, citrate or lactate.
