About The Detailed Introduction Of Sunflower Seed Protein?

Sunflower seed protein powder is a protein product made from defatted sunflower seed cake and removed the shell and phenolic acid compounds such as chlorogenic acid and caffeic acid. The main component is globulin (about 70% to 79%), followed by albumin and a small amount of gluten and gliadin. In the amino acid composition, the content of lysine is low, while the content of other essential amino acids is high.

Sunflower seed protein is a protein extracted from sunflower seeds and has rich amino acid composition and nutritional value. Sunflower seed protein is usually found in powder form and can be used in food processing, nutraceutical production and other industrial areas.
Contains a variety of essential amino acids, especially lysine, isoleucine and threonine. It's also rich in fiber and antioxidants, which promote cell health and boost immunity. Since sunflower seed protein is dairy- and soy-free, it is also suitable for people with dairy and soy allergies.
In terms of food processing, sunflower seed protein can be used to make vegetarian products, protein drinks, energy bars, cereals, etc. It has good solubility and emulsification properties and can be used to increase the protein content of products, improve taste and texture, and enhance the nutritional value of products.
In the field of health product production, sunflower seed protein can be made into protein powder, protein nutritional drinks, protein nutritional tablets, etc., to provide the human body with essential amino acids, supplement the nutrients needed by the human body, promote health and enhance immunity.

In the amino acid composition of sunflower seed protein, the content of lysine is higher than that of cereal protein but slightly lower than that of soybean protein and animal protein, and other various amino acids have a good balance. Comparing its amino acid composition with the FAO value, except for lysine content, the contents of other essential amino acids are higher than or similar to the FAO value, so lysine is the first limiting amino acid of sunflower seeds. Although low in lysine, its effective lysine content can be as high as 90%. Sunflower protein is rich in sulfur-containing amino acids such as methionine. Compared with most vegetable proteins, sunflower protein has a better digestibility (90%) and a higher biological value (60%).

Protein composition

Sunflower seed kernels contain 21% to 30% protein, and sunflower seed cake after oil extraction generally contains more than 50% protein. The protein content of sunflower seeds is 55% to 60% of globulin, 17% to 23% of albumin, 1% to 4% of gliadin, and 11% to 17% of gluten. The combined non-protein nitrogen and insoluble residues are less than 11% of the total nitrogen content. The solubility of sunflower seed protein in aqueous solution, salt solution and ethanol solution is 20%, 50%-60% and 3% respectively. Using gel chromatography, ultrafiltration, electrophoresis, etc., it was qualitatively found that the molecular weight of sunflower seed protein ranges from 10 to 450kDa, the molecular weight of the main component is 125kDa, and the average molecular weight is 180kDa. It contains 6 to 7 protein components. Research has found that sunflower seed protein is mainly composed of two components, 7-8S and 11-12S. The isoelectric point of sunflower seed protein is pH 4.0.

nutritional properties

The chemical composition of sunflower seeds will vary depending on the variety and growing environment. Domestic sunflower seed kernels usually have a fat content of 40% to 68%, a protein content of 21% to 30%, a carbohydrate content of 2.0% to 6.5%, a crude fiber content of 6.0%, and an ash content of 3.2 %～5.4%. Sunflower seed cake after oil extraction generally contains 29% to 43% crude protein, 4% to 15% crude fat, 7% to 23% cellulose, 3% to 19% moisture, and 7% to 10% ash.
In the amino acid composition of sunflower seed protein, the lysine content is higher than that of cereal protein, but slightly lower than that of soy protein and animal protein. The other various amino acids have a good balance. Comparing its amino acid composition with the FAO value, except for lysine content, the contents of other essential amino acids are higher than or similar to the FAO value, so lysine is the first limiting amino acid in sunflower seeds. Although the lysine content is low, its effective lysine content can be as high as 90%. Sunflower seed protein is rich in sulfur-containing amino acids such as methionine. Compared with most plant proteins, sunflower seed protein has good digestibility (90%) and high biological value (60%).
