PURPOSE: A producing method of plant material powder using the enzymatic treatment is provided to maintain or improve the functionality of plant materials in the original material state.CONSTITUTION: A producing method of plant material powder using the enzymatic treatment comprises the following steps: inserting water, protopectinase, and plant materials into a reactor stirring the mixture for relaxing plant cells, and centrifugal-separating the mixture to obtain precipitates adding water to the precipitates, and heating the mixture at 100 deg. C for 20-30 minutes for inactivating enzyme and freeze-drying and crushing the precipitates. 0.1%(w/v) of protopectinase is mixed with other ingredients in the reactor. The pH inside the reactor is 4-6, and the temperature inside the reactor is 30-50 deg. C.COPYRIGHT KIPO 2013[Reference numerals] (AA) Conventional way of grind-processing (BB) Protopectinase treatment processing of this provided invention (CC) Destroying cell membranes and cell walls (DD) Maintaining the shape of single cells본 발명은 프로토펙티나아제(protopectinase) 처리에 의한 식물 소재 분말의 제조 방법에 관한 것으로, 기원식물(起源植物)의 성분이 그대로 보존된 즉, 생명 활성이 그대로 보유된 식물세포를 포함한 분말을 수득할 수 있어, 기능성식품, 화장품 등의 첨가 소재로 사용할 수 있다.
