| Uses: |
| This product is widely used in trades such as
foodstuff, medicine, chemical industry and light
industry etc., and is chiefly used to make the
tartaric acid salts , like antimony potassium
tartrate, potassium sodium tartrate. Served as
beer vesicant and foodstuff sourness agent and
flavoring etc at the foodstuff trade and its sourness
is the citric acid 1.3 times, and especially is
suitable to do the sourness agent of the grape
juice. This article is appraised as the excellent
food additive by the FAO/WHO experts committee
. It also has the very important effect in tannage,
photograph, glass, enamel and telecommunication
equipment etc. |
