Maltose is a colorless crystal, usually containing one molecule of crystal water. Melting point 102℃, easily soluble in water, and the sweetness is 40% of sucrose. There are two isomers, α -and β-,and the ratio of α -and β -maltose in aqueous solution is 42:58. The molecular formula of crystalline β -maltose containing one molecule of water is β-c12h22o11H2O.
If crystal water is removed, β -maltose will be converted into α-maltose, so it is not easy to obtain anhydrous β -maltose. Commercially available crystalline maltose is mainly hydrous β-maltose, of which 5%- 10% has been converted into α-maltose.
Extended data
Maltose function:
1, detoxification and beauty: maltose can detoxify and beauty, and promote the absorption of minerals such as calcium, magnesium and zinc.
2, moistening the lungs to dry: can be used to treat qi deficiency, fatigue, abdominal pain, lung deficiency, chronic cough and asthma.
3, spleen and soft liver: maltose can spleen and soft liver, but it should be noted that children are not full of viscera, hypoplasia, and because "the liver is often surplus, the spleen is often insufficient", so they often get sick because of the disharmony between liver and spleen, and maltose itself contains more sugar.
