Scylla serrata is rich in fat and unsaturated fatty acids (UFA). The unsaturated fatty acids in muscle are 74.58%, EPA is as high as 18.04%, and DHA is 13.52%. The content of unsaturated fat in Scylla serrata is very high, especially omega-3 fatty acids, EPA and DHA, which cannot be synthesized by human body. EPA can obviously reduce the values of triglyceride (TG) and cholesterol (TC) in serum, prevent platelet aggregation, delay thrombosis, prevent cardiovascular and cerebrovascular diseases and prostatic hyperplasia, and DHA can promote brain development, enhance brain learning and memory ability, and prevent brain aging.
