In wine industry application, tartaric acid is the most commonly used acidity regulator for grape wine, fruit wine and sparkling wine: it corrects insufficient acidity of under-ripe grape raw materials, stabilizes wine pH value, inhibits bacteria spoilage, controls potassium bitartrate crystallization precipitation, clarifies wine body and optimizes taste layering and storage stability. For food processing field, it is compounded with baking soda to make slow-release leavening agent for cake, biscuit and puff pastry production; also used as acidity modifier, antioxidant synergist and flavor stabilizer for hard candy, chewing gum, fruit drinks and preserved fruit products. In pharmaceutical industry, tartaric acid acts as acid source for effervescent tablets, chelating stabilizer for oral preparations and solubility regulator for topical pharmaceutical formulations. Many overseas winery and high-end food buyers complain about unstable acidity, easy caking and excessive impurities from low-grade tartaric acid suppliers; our multi-stage recrystallization purification and moisture-proof sealing packaging completely solve these quality defects, protecting your finished product brand reputation and shelf stability.

Standard packaging is 25kg PE lined woven bag, jumbo bag bulk container shipment is customizable for large-volume orders to reduce unit logistics expenditure.
