3. Due to the mild and moderate sour taste of lactic acid, it can also be used as the first choice sour agent for well-prepared soft drinks and fruit juices;
4. When brewing beer, adding an appropriate amount of lactic acid can not only adjust the pH value to promote saccharification, but also benefit yeast fermentation, improve the quality of beer, increase the flavor of beer, and extend the shelf life. It is used in white wine, sake and fruit wine to adjust pH, prevent the growth of bacteria, enhance sour taste and refreshing taste; buffer type lactic acid can be used in hard candy, fruit candy and other confectionary products, with moderate sour taste and low sugar conversion rate. Lactic acid powder can be used for powdering various candies as a powdery sour agent;
