| Uses | 1. In the pharmaceutical field, maize starch can be used as a diluent and disintegrant for tablets, helping drugs to form and disintegrate in the body and promoting drug absorption. 2. In the food industry, it is often used for thickening, 勾芡 (thickening sauces), making pastries, etc., which can improve the texture and taste of food. 3. It is also widely used in chemical and other industries, for example, as a raw material for the production of starch sugar, amino acids and other products. 4. Maize is recognized worldwide as a "golden crop", with the content of fat, phosphorus, and vitamin B2 ranking first among cereal foods. Maize starch made from maize as raw material also has certain nutritional value. It is suitable for the general population to eat, especially suitable for patients with arteriosclerosis, coronary heart disease, hypertension, fatty liver, obesity, etc. to eat appropriately. |
