Chemical properties

White to cream colored powder

The Uses of Sodium caseinate

Sodium Caseinate is the sodium salt of casein, a milk protein. it is used as a protein source and for its functional properties such as water binding, emulsification, whitening, and whipping. it is used in coffee whiteners, nondairy whipped toppings, processed meat, and desserts.

The Uses of Sodium caseinate

Casein is the phosphoprotein of fresh milk; the rennin-coagulated product is sometimes called paracasein. British nomenclature terms the casein of fresh milk caseinogen and the coagulated product casein. As it exists in milk it is probably a salt of calcium. Casein is not coagulated by heat. It is precipitated by acids and by rennin, a proteolytic enzyme obtained from the stomach of calves. Casein is a conjugated protein belonging to the group of phosphoproteins. The enzyme trypsin can hydrolyze off a phosphorus-containing peptone. The commercial product also known as casein is used in adhesives, binders, protective coatings, and other products.
The purified material is a water-insoluble white powder. While it is also insoluble in neutral salt solutions, it is readily dispersible in dilute alkalies and in salt solutions such as those of sodium oxalate and sodium acetate.

The Uses of Sodium caseinate

α-Casein can be an immunogen in young children, and anti-α-casein antibodies have strong cross-reactivity with insulin. This effect can explain the uncommon insulin autoimmunity, but it does not appear to progress to Type I diabetes.

Definition

Though commonly regarded as the principal protein in milk (approximately 3%), casein is actually a colloidal aggregate composed of several identifiable proteins together with phosphorus and calcium. It occurs in milk as a heterogeneous complex called calcium caseinate, which can be fractionated by a number of methods. It can be precipitated with acid at p H 4.7 or with the enzyme rennet (rennin). The product of the latter method is called paracasein, the term being applied to any of the casein fractions involved, i.e., α, β, κ, etc.

What are the applications of Application

Sodium caseinate is suitable for:
1.the preparation of casein-based diets to investigate nutritional effect of vitamin E in diets for Litopenaeus vannamei postlarve
2.in an assay to determine the activity of a three-enzyme solution containing trypsin, chymotrypsin and peptidase
3.a study to investigate the effects of bovine somatotropin (bST) administration and abomasal casein infusion on nitrogen metabolism in Holstein steers
4.as constituent of blocking solution in immunoblotting.

Biochem/physiol Actions

α-Casein can be an immunogen in young children, and anti-α-casein antibodies have strong cross-reactivity with insulin. This effect can explain the uncommon insulin autoimmunity, but it does not appear to progress to Type I diabetes.

Safety Profile

Questionable carcinogen with experimental tumorigenic data. When heated to decomposition it emits toxic fumes of NanO.
