Goat milk protein fibers and preparation method thereof

Abstract

The invention discloses a preparation method of goat milk protein fibers, and solves the problems of poor degreasing effect and poor quality. The preparation method comprises the following steps of 1, taking goat milk, adding a nonionic surfactant, stirring, removing an upper-layer substance, adding ethanol, keeping the temperature for 0.5-1.0 h, removing the upper-layer substance, heating until boiling, filtering and drying to obtain goat milk protein powder; 2, dissolving goat milk protein powder in a sodium hydroxide solution, filtering, adding a cyclodextrine solution, dissolving step by step, stirring and mixing to obtain a goat milk protein solution; 3, quantitatively adding a cross-linking agent into the goat milk protein solution, carrying out defoaming treatment, mixing the goat milk protein mixed solution with viscose according to a ratio, and carrying out defoaming; 4, carrying out two-bath wet spinning on the mixed solution to obtain viscose trickles; 5, enabling the viscose trickles to be coagulated and formed through a coagulating bath, and obtaining fiber tows through a solidifying bath; 6, enabling the fiber tows to be subjected to aftertreatment, and obtaining the goat milk protein fibers. The method has the advantages of improving the degreasing effect and the fiber quality and the like.

Description

technical field [0001] The invention relates to a functional cellulose fiber, in particular to a goat milk protein fiber and a preparation method thereof. Background technique [0002] Goat milk proteins are mainly casein and whey proteins. The ratio of casein to whey protein in goat milk, cow milk and human milk is roughly 75:25 in goat milk, 85:15 in cow milk, and 60:40 in human milk. It can be seen that the content of goat milk is lower than that of cow's casein, and the content of whey protein is higher, which is close to that of human milk. Under the action of gastric acid, casein can form larger coagulums, the higher the content, the lower the protein digestion, so the digestibility of goat milk protein is higher than that of cow milk. The mineral content of goat milk is 0.86%, which is 0.14% higher than cow's milk. Goat's milk contains more elements than cow's milk, mainly calcium, phosphorus, potassium, magnesium, chlorine and manganese, etc. It is a high-quality ...
