The resulting scores for isoleucine, phenylalanine＋tyrosine, histidine, lysine, threonine, and tryptophan in cultured cuttlefish were 〉150. The ratio of EAA （essential amino acids）/nonessential amino acids in cultured cuttlefish （0.82） was higher than in the wild form （0.80）. All EAA amino acid scores for cultured cuttlefish were higher than their wild counterparts, except for histidine and tryptophan. Both groups of cuttlefish possessed similar saturated fatty acid content, with the cultured containing much more total （E） monounsaturated fatty acids, E n-6 polyunsaturated fatty acids （PUFA）, and eicosapentaenoic acid （C20：5 n-3） but less E n-3 PUFA, arachidonic acid （C20：4 n-6）, and docosahexaenoic acid （C22：6 n-3） than their wild counterparts. Therefore, the present results suggest that these cultured cuttlefish were better than the wild form for human health. Notably, these results also indicate that the nutritional composition of these cuttlefish might have been significantly affected by diet.展开更多
