Abstract:
PURPOSE: Provided is a method for preparing the spherical microcapsule of the red ginseng or ginseng extract powders which is stable to the chemical reaction and non-irritative, and conceals the bitter taste of the red ginseng or ginseng by coating the red ginseng or ginseng extract powders with at least one of water soluble polymers. CONSTITUTION: The method for preparing the spherical microcapsule of the red ginseng or ginseng extract powders comprises a step for warming the solution obtained by adding sugar, water soluble starch or hydrophilic polymer to the purified water and then drying it to form the particulate solid state core seeds; a step for coating the core seeds with the red ginseng or ginseng extract powders to form the particulate of 500 to 800 micrometers, thereby preparing the rapid release type spherical microcapsule; a step for coating the rapid release type spherical microcapsule with the polymer coating solution in an amount of 20 to 40 % by total weight of coating film composition of a delayed release type spherical microcapsule to form the delayed release type spherical microcapsule of 1000 to 1200 micrometers; a step for hardening and drying the coating film of the delayed release type spherical microcapsule to a moisture content of 1 to 10 % by total weight of the coating film capsule composition; and a step for meshing the dried microcapsule to 1000 to 1200 micrometers.
Abstract:
PURPOSE: A novel method for preparing α-L-aspartyl-L-phenylalanine methyl ester·HCl salt is provided, to reduce the amount of by-products, to allow the by-products to be reused after hydrolysis and to increase the production yield by 20% or more. CONSTITUTION: The method comprises the steps of reacting L-aspartic acid with trimethyl silyl chloride in the presence of an alcohol solvent to esterify the β-COOH selectively to obtain α-L-aspartyl-L-phenylalanine methyl ester·HCl. Preferably the alcohol solvent is selected from the group consisting of methyl alcohol, ethyl alcohol, allyl alcohol and benzyl alcohol. Preferably the method comprises further the steps of protecting an amine group with -CHO, Boc, benzyloxycarbonyl group, or -C(O)OR¬2 (R2 is methyl. ethyl or isobutyl group) by using acetic anhydride and formic acid.
Abstract:
PURPOSE: A novel microorganism capable of producing conjugated linoleic acid, a capsulated composition comprising the same, and a preparation method thereof are provided. The microorganism has high conjugated linoleic acid production yield and gastric juice and bile acid tolerance. CONSTITUTION: A microorganism capable of producing conjugated linoleic acid is provided, wherein the microorganism is Bifidobacterium breve CBG-C2 KACC 91001 and KCTC 10462BP, Bifidobacterium pseudocartenulatum CBG-C4 KACC 91003, and Enterococcus faecium CBG-C5 KACC 91002 and KCTC 10208BP. The capsulated composition for prevention and treatment of diseases capable of being inhibited by the conjugated linoleic acid, such as cancer, sclerosis of the arteries, diabetes and corpulence comprises the microorganism capable of producing conjugated linoleic acid.
Abstract:
PURPOSE: Mutant genes of human beta, beta-carotene 15, 15'-dioxygenase having improved enzyme activity are provided, so that enzyme proteins expressed from the mutant genes can be used in various fields related to the vitamin A production. CONSTITUTION: Mutant genes of human beta, beta-carotene 15, 15'-dioxygenase are produced by error-prone PCR using a human beta, beta-carotene 15, 15'-dioxygenase gene as templates, and have the enzyme activity of the expressed protein of 1100 pmol/h. A method for producing vitamin A comprises digesting beta-carotene using the expressed human beta, beta-carotene 15, 15'-dioxygenase. A method for producing vitamin A comprises transforming a host cell using the mutant genes of human beta, beta-carotene 15, 15'-dioxygenase, and culturing the transformed host cell in a medium, wherein the host cell is a plant cell, a prokaryotic cell, a yeast cell, an insect cell, a mammal cell or a poultry cell.
