Composite cow milk protein composition, and preparation method and application thereof

Abstract

The invention relates to the field of protein compositions, specifically to a composite cow milk protein composition, and a preparation method and an application thereof. The composite cow milk protein composition provided by the invention comprises the following raw materials in parts by weight: 20-50 parts of cow milk protein, 5-8 parts of soyabean lecithin, 0.5-2 parts of fructo-oligosaccharide, 1-1.5 parts of galactooligosaccharide, 0.5-1 part of compound vitamin, 0.3-0.6 part of a mineral substance, 0.1-0.3 part of a lotus leaf powder extracting solution and 1-3 parts of a stabilizer. Thecomposite cow milk protein composition provided by the invention has the advantages of simple preparation method, safety, health, fine and smooth taste, high stability, long shelf life and applicability to being used by cow milk allergy patients.

Description

technical field [0001] The invention relates to the field of protein compositions, in particular to a compound milk protein composition and its preparation method and application. Background technique [0002] Milk protein is mainly composed of casein and whey protein. Casein is the protein precipitated from milk at 20°C and pH 4.6. The rest of the protein dissolved in whey is called whey protein. Whey protein It includes β-lactoglobulin, α-lactalbumin, serum albumin, immunoglobulin and other trace proteins, such as copper and zinc-superoxide dismutase. Except for serum albumin and immunoglobulin from blood, all casein and whey proteins are synthetic products of milk secreting cells in the mammary gland, and bovine milk protein is mainly used as food additives.

[0003] Chinese patent document CN108064962A discloses a compound protein composition, a compound protein fermented milk base material, a compound protein beverage that can be stored at room temperature and its preparation, wherein the mass ratio of soybean protein to milk protein is 5-6:4-5, the The composite protein composition can greatly shorten the fermentation time of the fermented milk base material and the acidic composite protein beverage, and has a longer shelf life, because a certain amount of stabilizers (pectin, gellan gum, carboxymethyl Sodium cellulose, phosphate, soybean polysaccharides, etc.), although it can improve the stability of the product, it may increase the viscosity and rough taste of the protein drink, affecting the consumer experience, and the protein drink is not suitable for patients with Drinking by patients with milk allergies, therefore, there is room for improvement
