摘　　要：我国的海带产量巨大,但海带精深加工产品较少,海带护绿是制约精深加工的重要因素之一。海带失绿是因H^(+)取代了叶绿素的卟啉环中的Mg^(2+)而生成脱镁叶绿素所致。针对海带在加工贮藏过程中的变色失绿现象,本文对海带的变色机理和加工中常用的护绿技术进行了综述,以期为海带的护绿技术研究提供参考。The output of Laminaria japonica is huge in China,but there are less L.japonica deep-processing products.L.japonica green protection is one of the important factors restricting deep-processing.The chlorosis of L.japonica is caused by H^(+) replacing Mg^(2+) in the porphyrin ring of chlorophyll,resulting in the formation of pheophytin,which makes L.japonica lose green.In view of the discoloration and chlorosis of L.japonica during processing and storage,this paper summarized the discoloration mechanism of L.japonica and the common green protection technologies in processing,in order to provide enlightenment for the green protection technologies direction of L.japonica.
