What can replace defoamer

Introduction: many additives are used in food, defoamer is a very common food additive, so, what can replace the consumption of defoamer? Can defoamer be used Bubbles and bubbles are often accompanied by people's life and production Sometimes they need to be used, such as floatation, fire fighting, dust removal, washing, making foam ceramics and plastics, etc sometimes they need to be eliminated, such as fermentation, coating, paper making, printing and dyeing, elimination of internal organs flatulence, boiler water, waste water treatment and prism (or glass) manufacturing The so-called "bubble" or "bubble" refers to the existence of insoluble gas in a liquid or solid, or in an independent bubble surrounded by their film Many bubbles gather together, separated from each other by a thin film called foam Bubble is a kind of dispersed system with gas / liquid, gas / solid and gas / liquid / solid interfaces, the latter is common in ore dressing and oil field systems It is normal to produce a small amount of foam in the food industry, but too much foam can cause heat spillage and fermentation spillover, resulting in waste and environmental pollution This is the use of defoamer to control excessive foam in food Defoamers are mostly liquid compound products, mainly divided into three categories: mineral oil, organosilicon and polyether Mineral oil defoamer is usually composed of carrier and active agent The carrier is a material with low surface tension Its function is to carry and dilute The commonly used carriers are water, fatty alcohol, etc the role of active agents is to inhibit and eliminate froth, commonly used wax, aliphatic amide, fat and so on There are many functions of defoamer in food, so what can replace defoamer What about? We can choose natural oil as a kind of antifoaming agent instead of edible antifoaming agent, which mainly includes peanut oil, corn oil, soybean oil, rice sugar oil, tea seed oil and cottonseed oil Peanut oil is better, but because there is no hydrophilic base in the oil ester molecule, it is difficult to spread in the foaming medium, so its antifoaming performance is poor and the amount is large, generally it is material 0.1% ～ 0.2% of the total, because the natural oil contains a certain amount of biotin, such as too much oil, it will cause excessive growth of bacteria, resulting in the decline of metabolites At present, in the domestic production process of ammonia acid, natural oil is added for defoaming Can defoamer be used? Defoamer is a food additive approved by the state, which means that its use is not harmful to human beings, but there is a certain dose standard for the use of defoamer in the approved food in China Therefore, only the edible defoamer used within the specified range can be used We should pay attention to it You can pay more attention to Baibai safety net, learn more about food safety and learn to use food safety detector Editor in charge: he xianrob
