NUTRITIONAL EVALUATION ON OMMASTREPHES BARTRAMI

The nutritional composition of Ommastrephes bartrami was studied in this paper. With high proportion in the edible portion of red oceanic squid it accounts for 80% of its body weight, in which the tube muscle amounts to 50% and viscera and wastes 20%. The experimental results show that in the edible portion of red oceanic squid the contents of crude protein and fat are approximately 20% and 1 %, respectively as well as trace minerals such as calcium, phosphorus, iron and zinc. Moreover, the amino acid composition in crude protein is relatively complete and the essential amino acids amount to 45. 70% nearly equivalent to egg protein of 48. 92%, particularly in the content of lysine accounting for 9. 92% of the total. The viscera of red oceanic squid contain an abundant amount of protein and fats, in which crude protein and fat are 13. 78% and 19. 46% respectively. It is worthy to note that the fat in red oceanic squid contains 86% of unsaturaed fatty acids in which EPA and DHA amount to 36% of the total. These experimental data can be applied to the development of red oceanic squid sales market and its processing.
