摘要：
The present invention relates to a method for preparing a natural antibacterial and antioxidant agent using bamboo leaves, and more specifically, to a method for preparing a natural antibacterial and antioxidant agent using a bamboo leaf extract, capable of increasing the extraction yield and improving the purity of antioxidant material by using bamboo leaves to prevent the loss of active ingredients in the bamboo leaves. The method for preparing a natural antibacterial and antioxidant agent using a bamboo leaf extract, comprises: a step of first soaking washed bamboo leaves in a mixture solution of water, acetic acid, citric acid, and salt for 12-24 hours； a step of first drying the first soaked bamboo leaves, and then spraying alcohol on the bamboo leaves, followed by second drying until the moisture content reaches 5%； a step of granule-pulverizing the dried bamboo leaves； a centrifugal thermal burning step of putting the granule-pulverized bamboo leaves in a centrifugal thermal burning machine, uniformly spraying alcohol thereon, performing low-rate rotation in a low-temperature condition, closing the thermal burning machine if the flavor begins to emit, and then performing high-rate rotation in a high-temperature condition； a step of putting the bamboo leaves, which have gone through the thermal burning step, in a mixture solution of water, alcohol, citric acid, salt, and vinegar, adding cellulase, lipase, vitamin, calcium, and magnesium thereto, followed by second soaking for 12-24 hours to perform enzymatic lysis； and a step of extracting active ingredients using a supercritical extraction method through separation by solubility.본 발명은 대나무 잎을 이용한 천연 항균, 항산화제 제조방법에 관한 것으로서, 보다 상세하게는 대나무 잎을 이용하여 대나무 잎 내의 유효성분의 손실을 방지하여, 추출 수율과 항균, 항산화성 물질의 순도를 향상시키는, 대나무 잎 추출물을 이용한 항균, 항산화제 제조방법에 관한 것이다. 본 발명의 대나무잎 추출물을 이용한 천연 항균, 항산화제 제조방법은 세척된 대나무 잎을 초산, 구연산, 소금이 혼합된 물에 12~24시간 1차 침지시키는 단계； 1차 침지된 대나무 잎을 1차 건조시킨 후, 술을 분사하고 수분 함량이 5%가 될때까지 2차 건조시키는 단계； 건조된 대나무 잎을 그래률 파쇄하는 단계；
