Application Introduction of Acid Casein
Acid casein is a white or pale yellow amorphous powder made from skimmed milk via acid precipitation. It is insoluble in water but soluble in dilute alkaline solutions, featuring excellent emulsifying, film-forming and gelling properties. Its versatile applications span across food, daily chemical, pharmaceutical and industrial sectors, with specific uses as follows:
1. Food Industry (Core Application)
- Dairy products: Serves as a key raw material for making cheese, yogurt and cream, improving product thickness, texture and stability.
- Baked goods: Acts as a modifier for bread and cakes, enhancing dough toughness, reducing staling rate and extending the shelf life of finished products.
- Meat products: Functions as an emulsifier and binder for sausages and hams, optimizing meat structure, preventing oil-water separation and improving product taste.
2. Daily Chemical Industry
- Cosmetics: Used as a thickener and emulsifier in creams and lotions, enhancing product skin feel and stabilizing the formulation system.
- Toothpaste: Works as a binder to prevent toothpaste from stratifying and caking, ensuring uniform texture of the paste.
3. Pharmaceutical Field
- Pharmaceutical excipient: Serves as a carrier for sustained-release capsules and tablets, regulating drug release rate and improving the bioavailability of active ingredients.
- Microbiological culture medium: Acts as a nitrogen source for microbial culture, providing essential nutrients for biopharmaceutical R&D.
4. Industrial Sector
- Paper industry: Functions as a sizing agent, improving the water resistance and mechanical strength of paper, suitable for high-grade cultural paper and packaging paper production.
- Leather industry: Serves as a tanning agent, enhancing the softness and gloss of leather, making the finished leather more durable and wearable.
