Sodium Caseinate Powder

What is Sodium Caseinate?

Sodium Caseinate Powder, also known as casein, is easily soluble or dispersed in water. The aqueous solution is neutral and acidification produces casein precipitation. It is a compound extracted from casein, a protein in mammalian milk. It is the main protein in milk. Its opaque, white appearance is caused by casein.
It has a wide range of applications in the food, cosmetics and personal care industries. It can be separated from milk and used alone as a thickening, texturizing and stabilizing additive for various foods. It is also a component of many milk-based products such as ice cream and cheese. It can be used as a food additive with high safety. It is generally permitted for use in countries around the world. Because of its good emulsification and thickening effects, it is widely used in almost all food industries.

Characteristics

Thickening property
It is a high molecular weight protein, which can have a certain viscosity in aqueous solution. In industrial production, it can be low viscosity, medium viscosity and high viscosity casein sodium depending on the production process.

Emulsifying property
Because its molecules have hydrophilic groups and hydrophobic groups, it has a certain emulsifying property. The emulsifier made of casein sodium has better stability than the emulsifier made of whey protein, soy protein, etc.

Thermal stability
It has good thermal stability. Most protein molecules such as eggs and soy proteins are connected by hydrophobic groups and hydrophilic groups, which are easily denatured by heat. The emulsion can be sterilized at 120°C without destroying its stability and functionality. This is mainly because it can form a strong hydrophilic protein film of lgm on the surface of fat globules, which will not cause the destruction of the emulsification system.

Foaming property
It has good foaming property, which can be widely used in cold foods such as ice cream to improve their texture and taste.

Benefits

Nutritional supplement
Rich in a variety of essential amino acids and trace elements needed by the human body, Sodium Caseinate Powder is a high-quality source of protein that helps to enhance the nutritional value of food. It is particularly suitable for nutritional supplements for children, the elderly, athletes and patients recovering from surgery.

Improving food texture and taste
As an emulsifier, stabilizer and thickener, sodium caseinate can improve the texture and taste of food, making it more delicate, smooth and elastic.

Increasing water retention and oil retention of food
With good water retention and oil retention, it can help food retain moisture and oil during processing, storage and sales, reduce water loss and oil precipitation, thereby extending the shelf life of food and maintaining the freshness of food.

Easy to process and store food
It can improve the processing performance of food, such as improving the plasticity, formability and heat resistance of food, making food processing more convenient. At the same time, its good stability also helps to maintain the quality of food during storage and reduce food deterioration caused by environmental factors.

Stabilization Mechanism

It is mainly adsorbed to the surface of fat globules through electrostatic repulsion and forms a protective film, which then exerts a steric hindrance effect to maintain the good dispersion state of fat globules in the emulsion. Studies have used sodium caseinate to prepare nanoemulsions and explore its effect on the stability of the emulsion.

Applications

Food
In dairy processing, it can stabilize the structure and improve the uniformity of product texture. For example, in ice cream production, it can inhibit ice crystal formation and improve the fineness of taste; in cheese processing, it can promote the construction of protein network, help prevent water-oil separation, and extend the shelf life of products.

In meat processing, adding an appropriate amount can enhance the water holding capacity of minced meat, improve the slicing performance and elasticity of the product; it can play a very good bonding effect when used with TG enzyme, turning minced meat into whole meat.

In the production of plant protein beverages, by adjusting the interfacial tension, it can effectively prevent fat from floating and protein from precipitating, and improve product stability. As a baking improver, it can enhance the gas holding capacity of dough and slow down the aging of products.

Cosmetics
With hydrophilic groups, it forms a moisturizing barrier and improves the skin's ability to lock in moisture. As an emulsifier stabilizer, it can improve the dispersibility of physical sunscreens in sunscreen products and enhance comfort. Its cationic properties enable it to play a role in hair care products, forming a protective film on the surface of hair by adsorption, improving frizziness and enhancing gloss.

Medicine
Using its biocompatibility, it is developed as a drug delivery carrier, encapsulating active ingredients through nanotechnology to achieve targeted release and reduce the impact on healthy cells.

Agriculture and feed
As a high-quality protein source, it can partially replace the animal protein components in traditional feeds and promote the nutrient absorption of farmed animals. In aquaculture, its amino acid composition matches the needs of aquatic organisms and helps the development of larvae.
