this invention is a method of lotus leaf extract, fermentation, the yeast extract, the use of the material in the light of six and six on the products, raw materials, some of the lotus leaf to remove impurities, washing and drying stage (S1), as the extraction of lotus leaf. machine the validity of the solvent is extracted from the (S2)in the step (S2) extracted from the leaf extract of lactic acid bacteria fermentation, the fermentation to make the input stage (S3), the stage (S3) in the extract of lotus leaf effect, the sterilization effect is the stage (S4) and the sterilization is completed the effect of the filter is \uc5ec\uacfc\uae30\ub85c (including S5). in the step (S2), solvent, purifying and anhydrous ethanol (EtOH), which was selected to use.75 ~ 85 degrees the temperature of 1 ~ 5 hours of hot water extraction, and the step (S3) in the fermentation using the lactic acid bacteria fermentation to be with the hope that the will of all states in which the selected at least one bacteria for use in 5 hours, \ucd94\ucd9c\ubb3c leaf and 48 hours. for lactic acid bacteria fermentation to culture, the leaf extract of the fermentation to the structure.according to the invention a lotus leaf extract has anti obesity effect, synthetic coloring materials that can sense and effect, anti obesity health care food raw materials to processed foods and the development of its own can also, the price for the leaf to the creation of farmers income increasing in. the results can be expected본 발명은 연잎 추출물 발효방법, 그에 의한 발효추출물을 이용한 항비만 육가공 소재 및 육가공제품에 관한 것으로, 원료로서의 연잎을 선별하고 이물질을 제거하도록 세척하고 건조하는 단계(S1), 상기 건조된 연잎을 추출기에서 용매에서 유효성분을 추출하는 단계(S2), 상기 단계(S2)에서 추출된 연잎 추출물에 유산균 발효 균주를 투입하여 발효시키는 단계(S3), 상기 단계(S3)에서 발효된 연잎 추출물 발효액을 살균하는 단계(S4) 및 살균이 완료된 발효액을 여과기로 여과하는 단계(S5)를 포함하며, 상기 단계(S2)에서 용매로서 정제수와 무수에탄올(EtOH)중에서 선택된 어느 하나를 사용하며, 75~85℃의 온도에서 1~5시간 동안 열수추출하며, 상기 단계(S3)에서 발효에 사용되는 유산균 발효 균주는 락토바실러스속의 균주들중에서 선택된 적어도 어느 하나의 균주를 사용하며, 연잎 추출물에서 5 시간 내지 48시간 동안 상기 유산균 발효 균주를 배양하여 연잎추출물을 발효시키는
