Properties:
Widely used in food, medicine, chemistry and light industry, etc., Mainly used to manufacture
DL-Tartaric acid salts, such potassium sodium tartrate and used as beer foaming agent.
DL-Tartaric acid also applied in tanning, photo, glass, enamel and telecom materials industries. Its acidity is as 1.3 times as citric acid, so specially as acidifying agent for grape juice.
Packing:
25kg complex bags lined with double-layered kraft paper bags and film bag.
