PROBLEM TO BE SOLVED: To solve the problems of the putrefaction and the proliferation of sundry germs caused by the prolonged extraction of vegetable cell with low- temperature water by carrying out the low-temperature extraction of a component which has hitherto been extractable only by hot extraction. SOLUTION: Hard membrane of a vegetable cell is decomposed with an enzyme, especially cellulase and the treated cell is dried by freeze-drying, spray- drying, vacuum drying, or the like, and extracted in non-heated state using low-temperature water, water-alcohol mixture, edible oil and fat, or the like. |
