Fermentation

App Introduction
Antifoaming agents are critical additives in the fermentation industry—including alcohol fermentation, beer brewing, soy sauce and vinegar production, and the biofermentation of amino acids and enzyme preparations. They effectively break existing foam and provide long-lasting antifoaming performance by targeting surface-active substances such as proteins and sugars present in fermentation media (e.g., molasses, starch, soybean meal) as well as the abundant foam generated during aeration, agitation, and microbial metabolism. Excessive foam in fermentation systems can reduce the fill ratio of fermenters, lead to cell loss, and impede oxygen transfer, thereby compromising fermentation efficiency and product yield. Specialized food-grade antifoaming agents for fermentation must comply with food safety standards such as GB 2760, withstand moderate‑temperature, acidic or neutral operating conditions within the fermentation system, exhibit excellent compatibility with the fermentation medium and microorganisms, and not interfere with fermentation metabolism or product purity.
Application Value
Enhance the effective utilization of fermentation tanks and production efficiency, preventing raw material losses and workshop contamination caused by foam overflow; ensure efficient oxygen transfer to promote microbial growth and product synthesis, thereby increasing both the yield and purity of fermentation products such as ethanol, flavorings, and biopharmaceuticals; reduce the risk of microbial contamination during fermentation and stabilize batch-to-batch product quality; lower the complexity and cost of downstream separation and purification, while meeting food safety standards and preserving the final product’s flavor and quality.
