Silica sol or silica gel liquid, used for brewing soy sauce, can effectively absorb various impurities in soy sauce, improve the clarity of soy sauce, and prevent secondary precipitation and the reproduction of microorganisms. Compared with natural precipitation filtration, impurities can be separated more thoroughly in a short time.
Adding acid silica sol to the beer fermented solution can make the impure ions form agglomerates and be removed, making the product clear and bright.
Silica sol can also be used as a clarifying agent for rice wine, soy sauce, fruit juice, etc., without affecting the color, aroma and taste of the product. Moreover, silicon is not harmful to the human body.
