The total content of crude protein, fat and total sugar in flaxseed is as high as 84.07%. Flaxseed protein has a complete range of amino acids, and the content of essential amino acids is as high as 5. 16%. It is a plant protein with high nutritional value.

The content of α -linolenic acid in linseed oil is 53%. α -linolenic acid is an essential fatty acid for human body, which can be converted into eicosapentaenoic acid and docosahexaenoic acid in human body.

Extended data;

According to the national standard of linseed oil in China (GB/T8235-2008), the main fatty acids in linseed oil are linolenic acid 39.0%~62.0%, oleic acid 13.0%~39.0%, linoleic acid 12.0%~30.0% and palmitic acid 3.

Its fatty acid composition is characterized by containing a large number of omega-3 polyunsaturated fatty acids (α linolenic acid). α linolenic acid can be converted into DHA and EPA in the body, which plays an important role in maintaining adult blood lipid health and children's brain and vision development.

More importantly, α linolenic acid is one of the main omega-3 polyunsaturated fatty acids, and its content is very low in edible oils such as soybean oil, peanut oil, sunflower oil, olive oil and sesame oil. This characteristic of linseed oil is very important, and it is often used to supplement the above-mentioned vegetable oil, which is of great significance to maintain the balance of omega-6 and omega-3 polyunsaturated fatty acids in diet.
