The bioactive power of silkworm pupa protein peptides

Silkworm primary peptides refer to peptide fragments obtained by pretreatment or enzymatic hydrolysis of protein molecules extracted from silkworms. Silkworm primary peptide refers to the development stage of silkworm larvae before entering the primary stage. Usually at this stage, silkworms will form silkworm primary. After a certain biological process, silkworms are further rich in nutrients such as protein, nutrients, fats and vitamins, so the extracted silkworm peptides Protein peptides are also considered to have certain nutritional value.


What is the composition of silkworm pupae?

The investigation shows that pupa powder contains 7.6% moisture, 71.9% crude protein, 20.1% fat, and 4.0% ash based on dry matter. Mineral analysis shows high potassium content, low sodium/potassium ratio, and low levels of heavy metals.
Silkworm pupae have high monounsaturated and polyunsaturated fatty acid contents and low saturated fat content (Payne et al.). About 70%–80% of the fatty acid content of silkworm pupae is unsaturated, while about 1% is unsaponifiable matter in oil, including campesterol, β‐sitosterol, and cholesterol.


What is inside silkworm pupa?

Silkworm pupae protein contains 18 amino acids and is rich enough in essential amino acids to meet the amino acid requirements of humans and is beneficial to human health. Silkworm pupae oil contains a large number of unsaturated amino acids, especially Omega-3 fatty acids.

Essentially, silkworm pupae are a good source of protein, fat, minerals, and vitamins.  Compared to conventional food, they have higher content of three calorigenic nutrients (protein, fat, and carbohydrates), providing up to 230 kcal per 100g.

Studies have shown that silkworm protein peptide not only retains the nutrients and active ingredients of silkworm protein peptide, but also stimulates the physiological functions of the liver. Studies have shown that silkworm protein peptide has the function of reducing human liver cholesterol; it has a good preventive and therapeutic effect on coronary heart disease, atherosclerosis, hypertension, liver tumors and diabetes; silkworm protein peptide also has anti-fatigue and antioxidant properties. , anti-aging function; can be used to treat leukopenia, and has acute and chronic, toxic and physiological functions.
