چکیده
Squids belong to the cephalopod family, which composes more than ۵% of the total annual fishing volume of southern Iran as by- products; however, these do not have significant usage in Iran. This product was studied to extract the high-value products, i.e. marine oils rich in unsaturated multiple-band fatty acids from ۵۰kg squid (Loligo loligo) obtained from Chabahar fishing port and transferred to Urmia Research Center for further action. Extracting oil from squid was done by using the Dyer and Bligh standard method. The results indicated that ۱۳±۵% of wet weight of squid was oil; the percentage and profile of the extracted oils were made by using the G.C method. The results showed that squid oil had ۲۹.۴۰% saturated fatty acids and ۲۳.۷۰% single- band unsaturated fatty acids, and the total value of the unsaturated multiple-band fatty acids of the same was ۴۰.۲۰%. Also the contents of arachidonic acid was ۲.۷۸%, linolenic acid was ۳.۱۰%, linoleic acid was ۵.۲۰%, docosahexaenoic acid (DHA) was ۱۵.۴۰%, and eicosapentaenoic acid (EPA) was ۹.۶۰% of the total fatty acids. The results demonstrate that squid is considered for the first time as the new and rich source of Omega-۳ and Omega-۶.کلیدواژه ها
