The several enzymes reaction which involve the quality change of fresh vegetables, such as chlorophylase, polyphenol oxidase, lypoxygenase, C-S-lyase, myrosinase and enzymes related lignification were reviewed. Numerous enzyme reaction continuously proceeds to the deterioration of vegetables after harvest due to the respiration and biochemical metabolism reaction, especially in case of physical injuring. It is extremely important to inhibit and to control these enzyme reaction in order to maintain the organoleptic and nutritional quality of fresh vegetables.
