Application

1.Food field

Seasoning: It has a certain umami taste and can be used as a food seasoning to enhance the flavor of food and improve the taste. Adding diGly peptide to condiments such as soy sauce and chicken essence can enhance the umami taste of the product and make it more rich and mellow.

Nutrient enhancer: DiGly peptide is a dipeptide composed of two glycine molecules, and glycine is one of the essential amino acids for the human body. Therefore, diGly peptide can be added to food as a nutritional enhancer to supplement the amino acids required by the human body and improve the nutritional value of food. Especially in some sports nutrition foods and special medical purpose formula foods, diGly peptide is widely used;

2.Cosmetic field

Skin protectant: DiGly peptide has antioxidant and moisturizing effects, which can protect the skin from free radical damage and reduce signs of skin aging. At the same time, it can also help the skin retain moisture, make the skin softer and smoother, and improve the elasticity and luster of the skin. Therefore, it is often added to skin care products such as creams, lotions, essences, etc.

Hair care agent: In hair care products, diGly peptide can play a role in repairing and protecting hair. It can penetrate into the hair fiber, enhance the toughness and strength of the hair, and reduce the phenomenon of hair breakage and split ends. In addition, diglycerin can also improve the glossiness of hair, making it smoother and easier to comb.
