Executive Standard: GB1987-2007/FCC8/BP2013/USP36/E330
Molecular Formula: MnSO4·H2O
MW: 169.019 CAS No.:7785-87-7 EINECS No.:10034-96-5
Character: colorless crystal or white translucent particles or white crystalline powder, odorless, very sour taste, slight deliquescence in moist air. It can be in the form of no hydrate or hydrate: when the citric acid is crystallized from hot water. When it is heated to 78 DEG C, hydrate will decompose and hydrate. Citric acid can be dissolved in absolute ethanol at 15 degrees celsius.
Package: 25kgs woven bag lined with plastic bag, according to the customer’s demand , Stored at draughty dry places.
Usage: mainly used as complexing agent, masking agent, chelating agent, buffering agent, the food industry is mainly used as sour agent, solubilizer, buffering agent, antioxidant, deodorization deodorization agent, flavor enhancer, gelling agent, toner. In addition, citric acid can inhibit bacteria, protect color, improve flavor and promote the transformation of sucrose. Citric acid also acts as a chelating agent to remove certain harmful metals. Citric acid can prevent the oxidation caused by enzyme catalysis and catalytic metal, thereby preventing frozen fruit discoloration
