The purpose of sodium alginate, what is the main purpose of sodium alginate?

　　Use of food-grade sodium alginate

　　Sodium alginate is used to replace starch and gelatin as the stabilizer of ice cream, which can control the formation of ice crystals, improve the taste of ice cream, and also stabilize mixed drinks such as sugar sorbet, sherbet and frozen milk. Many dairy products, such as refined cheese, whipped cream, dry cheese, etc., can prevent the food from sticking to the packaging by using the stabilizing effect of sodium alginate, and can be used as the cover of the upper milk jewelry, which can make it stable and prevent the icing crust from cracking.

　　Sodium alginate is used as thickener in salad sauce, pudding, jam, tomato sauce and canned products to improve the stability of products and reduce liquid leakage.

　　Adding sodium alginate in the production of dried noodles, vermicelli and rice flour can improve the cohesiveness of the products, make them have strong tensile force, large bending degree and reduce the breakage rate, especially for gluten with low flour content. Adding sodium alginate to bread, cakes and other products can improve the uniformity of internal tissue and water holding function of products and prolong storage time. Adding it to frozen sweets can provide thermal fusion protection layer, improve fragrance escape and improve melting point.

　　Sodium alginate can be made into all kinds of gel foods, which keep a good colloidal shape without exudation or contraction, and is suitable for frozen foods and artificial imitation foods. It can also be used to cover fruits, meat, poultry and aquatic products as a protective layer, which is not in direct contact with air and prolongs storage time. It can also be used as a self-coagulation forming agent for bread icing, stuffing, pastry coating and canned food. The original shape can still be maintained in high temperature, freezing and acidic media. It can also replace agar to make elastic, non-sticky and transparent crystal soft candy.

　　Application of printing and dyeing grade sodium alginate

　　Sodium alginate, a dyeing assistant of reactive dyes, is used as reactive dye color paste in printing and dyeing industry, which is superior to grain starch and other sizes. Printed textiles have bright patterns, clear lines, high color feed, uniform color, good permeability and plasticity. Algae gum is the best size in modern printing and dyeing industry. It has been widely used in the printing of cotton, wool, silk, nylon and other fabrics, especially in the preparation of pad printing paste.
　

　　Sizing on Warp In China textile industry, seaweed gum mixed with starch or used instead of starch to prepare warp sizing can not only save a lot of grain, but also make warp fibers lint-free, friction-resistant and have less broken ends, thus improving weaving efficiency. Algae gum is effective for both cotton fiber and synthetic fiber.
