Casein phosphopeptide (CPP) is a polypeptide isolated and purified from casein in milk after enzymatic hydrolysis, which has a high degree of phosphorylation and a long peptide chain. Due to its special structure and properties, casein phosphopeptide has a wide range of application prospects in the fields of food, medicine and cosmetics. This article will introduce the basic properties, preparation methods, application fields and future development prospects of casein phosphopeptides.
1. The basic properties of casein phosphopeptides.
Casein phosphopeptide is a white or pale yellow powder with high water solubility and stability. Its molecular weight is small, making it easy to be absorbed and utilized by the body. Casein phosphopeptide contains a large amount of phosphate, has good chelation, and can combine with minerals such as calcium, iron, zinc, etc., to promote its absorption and utilization. In addition, casein phosphopeptides have good heat resistance and acid-base stability, and can maintain stability over a wide pH range.
2. Preparation method of casein phosphopeptide.
The preparation of casein phosphopeptides is mainly based on enzymatic hydrolysis and separation and purification. Firstly, the casein in milk is enzymatically hydrolyzed to obtain the hydrolysate, and then the high-purity casein phosphopeptide is obtained after separation and purification. At present, commonly used enzymatic hydrolysis methods include acid protease hydrolysis, alkaline protease hydrolysis and complex enzyme hydrolysis. Separation and purification methods include technologies such as ion exchange, gel filtration, and ultrafiltration.
3. Application fields of casein phosphopeptides.
1.Food additives.
As a new type of food additive, casein phosphopeptide has a wide range of applications in food. Because it has good chelation, it can be combined with minerals to improve the absorption and utilization of calcium, iron, zinc and other minerals in food, and has a good role in promoting children's growth and development. In addition, casein phosphopeptides can also be used to improve the taste and quality of food, such as improving the solubility and stability of food, delaying the oxidation and spoilage of food.
2.Pharmaceutical field.
Casein phosphopeptide also has a wide range of application prospects in the field of medicine. Due to its good biocompatibility and biological activity, it can be used to prepare drug carriers and drug controlled release systems. At the same time, casein phosphopeptide can also be used to prepare antibacterial agents, anti-inflammatory agents and antitumor drugs. In addition, casein phosphopeptides can also be used as an active ingredient in nutritional supplements and health supplements to improve human health.
3.Cosmetics field.
Casein phosphopeptides also have a wide range of application prospects in the field of cosmetics. Due to its good moisturizing, moisturizing and antioxidant properties, it can be used to prepare cosmetics such as **, creams, lotions, etc. At the same time, casein phosphopeptide can also be used as an active ingredient in sunscreens and whitening products to improve the efficacy and quality of products.
Fourth, the future development prospectsWith the continuous improvement of people's attention to food safety and health, the food additives industry is facing new opportunities and challenges. As a new type of food additive, casein phosphopeptide has a good development prospect. In the future, with the continuous improvement and perfection of production technology, the production cost of casein phosphopeptide will be further reduced, and its application in food, medicine and cosmetics will be more extensive. At the same time, with the in-depth research and understanding of casein phosphopeptides, its application in the fields of functional foods, health products and biomaterials will be further expanded.
