Usage

1. Scientific research and experiments: Maltose contains an aldehyde group in its molecular structure, which gives it reducibility, making it a reducing sugar. Therefore, it can undergo a silver mirror reaction with silver ammonia solution and can also react with freshly prepared alkaline copper hydroxide to form a brick-red precipitate. It can be hydrolyzed under certain conditions to produce two molecules of glucose. It is used as a biological culture medium, a polysulfide determination reagent, and a standard for colorimetric determination of brown in analytical chemistry.
2. In addition to being widely used in cold drinks and baked foods, high-maltose syrup is also extensively applied in pharmaceuticals and health foods. Due to its low osmotic pressure, high-maltose can replace glucose in intravenous infusions for patients; intravenous infusions made of pure maltose are less likely to cause blood glucose elevation. Since maltose syrup can penetrate into the fetal body, it can be used for fetal protection in pregnant women during the critical perinatal period. In traditional Chinese medicine, high-maltose syrup can tonify deficiency and moisten the lungs, and is mainly used to treat symptoms such as abdominal pain caused by middle deficiency and cough due to lung dryness. 3.
