본 발명은 키토산을 효모에 첨가함으로써 자가분해를 촉진시킴을 특징으로 하는 효모 추출물의 제조방법에 관한 것이다. 효모의 자가분해를 위해서, 지금까지는 유기용매가 주로 첨가되어 왔다. 그러나, 유기 용매는 자연산 물질이 아니므로 효모 추출물이 식품에 사용될때는 예를들면, 유기 용매가 완전히 제거되어야만 하는 문제와 같은 문제점들이 있다. 본 발명에 따르면, 효모의 자가분해를 촉진하기 위해 자연물질로부터 유도된 키토산을 사용하여 우수한 효모 추출물을 수득할 수 있다. The invention provides a method for preserving food, which comprises adding at least one compound selected from among protamine, chitosan and lysozyme to food and keeping the food in a substantially hermetically sealed state in the presence of a deoxidizer. This method makes it possible to prevent denaturation of food by, e.g., yeast, which has been difficult with the aid of a naturally occurring antibacterial substance.
