Abstract:In order to make high-value use of the squid Dosidicus gigas，the proximate composition，amino acid composition，fatty acid composition and mineral elements content of different tissues （head，muscle，viscera，eyes and neck）from squid Dosidicus gigas were analyzed and compared.The results showed that there were significant differences in the nutritional composition between different tissues of squid Dosidicus gigas.The moisture content was all over 75%，and the tissue of eyes had the highest value（84.85%）. The crude protein content was the highest（18.21%）and the crude fat content was almost the lowest（0.33%）in the muscle tissue.The crude fat （2.75%）and total sugar content （0.60%）of viscera were significantly higher than other tissues.All tissues contained 18 kinds of amino acids，and the content of essential amino acids in different tissues was all greater than 36%.Most of the AAS values were above 0.60，while most of the CS values were lower than the chicken egg pattern. 8 to 11 kinds of fatty acids were detected in different tissues. All of the unsaturated fatty acids content was higher than 64%.The highest amount of polyunsaturated fatty acids was found in the tissue of eyes （76.30%）.The tissues of muscle and neck were found to have the highest amount of DHA （46.83%）and EPA+DHA（61.49%），respectively.The macro-elements of K，Na and P were all abundant in the different tissues.The contents of Mg，Ca，Cu，Fe，Zn，Mn and Se in viscera were obviously higher than other tissues.
