Abstract: Grouper is a high quality fish. In recent years,with the rapid development of grouper breeding technology,the aquaculture production of grouper increased year by year,the annual output has exceeded one hundred thousand tons. Affected by China’s "seafood" consumer awareness,grouper preservation and processing technology is relatively lagging behind,therefore,understanding of the composition of grouper nutrition,preservation,processing technology status,it will help to promote the preservation of grouper and processing technology. In this paper,the research and development status of the grouper nutrition composition,keep alive technology,preservation technology(including low-temperature preservation,atmosphere or vacuum preservation,composite preservatives),processing technology(including frozen grouper,conditioning food,polypeptide products)and quality safety testing and other aspects of grouper were summarized. Combining with the new demands of industry and consumption,the development direction of grouper in fresh keeping,deep processing technology,maintaining of nutritional quality,quality and safety control and standardization processing are put forward.
