Release Date:
2021-02-04
Antifoaming agents, also known as defoamers, are food additives that reduce surface tension during food processing, thereby inhibiting foam formation or eliminating existing foam. In China, the approved antifoaming agents include emulsified silicone oil, high‑carbon alcohol fatty acid ester complexes, polyoxyethylene–polyoxypropylene pentaerythritol ethers, polyoxyethylene–polyoxypropylene amine ethers, polyoxypropylene glycerol ethers and polyoxypropylene–polyoxyethylene glycerol ethers, as well as polydimethylsiloxane—seven types in total.

Defoaming agents for food use are specially formulated for foam control in the food processing industry, also known as DSA‑5 defoamers. They are key products promoted by China’s food industry and are particularly valuable in contexts where many countries strictly limit silicon residues and prohibit the use of polyether‑based defoamers. These products offer unique advantages, including no adverse impact on product taste, rapid defoaming, long‑lasting foam suppression, and a defoaming efficiency of 96–98%. They are widely employed across numerous food‑related sectors, such as soybean products, dairy, pharmaceuticals, dairy beverages, sugar manufacturing, soy protein extraction, sauce and vinegar production, and cigarette‑filter adhesives. Moreover, owing to their superior performance, they are also utilized in synthetic latex production, metal cleaning, and other industries.
Food antifoaming agent What are its functions? This food antifoaming agent is refined using high-performance dispersants and emulsifiers. It features low dosage, safety, non-toxicity, and outstanding defoaming performance. It exhibits strong defoaming power and prolonged foam‑suppressing action; boasts excellent chemical stability, with superior heat resistance and oxidation resistance, minimal volatility, and resistance to chemical reactions with foaming media; is free of toxic side effects and harmless to human health; and is safe, convenient to use, and requires only a small amount.
Can defoamers be consumed? Food-grade defoamers are specially formulated for the food-processing industry and are a key product promoted by China’s food industry. They offer distinct advantages, including no adverse impact on product taste, rapid defoaming, long-lasting foam suppression, and a defoaming efficiency of 96–98%. As long as they are used within the limits set by national standards, these defoamers are safe for consumption—so you can rest assured.
