Ingredients of antifoam

Introduction: defoamer is commonly used as a kind of foam additive in food production What are the ingredients of food defoamer? Foam can be defined as a stable gas in a liquid medium Foam is a dispersion system of gases in liquid Gas is separated from many bubbles by continuous phase liquid Gas is dispersed phase and liquid is dispersed medium Foam is a thermodynamically unstable system It can not be stable The thermodynamic instability of foam is due to the large decrease in the total surface area of the system after the bubble breaking, resulting in the reduction of the energy (free energy) of the system Defoamer, also known as anti foaming agent, will produce many harmful foam in the process of industrial production, and need to add defoamer It is widely used to remove harmful foam produced in latex, textile sizing, food fermentation, biological medicine, pesticide, coating, petrochemical, paper making, industrial cleaning and other industries Because its purity is not high, and contains arsenic, lead and other heavy metals, it is harmful to human health, and may even cause cancer What are the ingredients of the food defoamer? The food defoamer is made of the excellent dispersing assistant and emulsifier The utility model has the characteristics of small dosage, safety, non toxicity and obvious defoaming effect At present, defoamers commonly used in the food industry are oils and aliphatic compounds, and emulsified silicone oil, which is a white emulsion emulsified by adding dispersant AIDS The main components of food grade defoamer include calcium carbonate, sorbitan fatty acid ester, silicone oil, food preservative, etc There are many kinds of defoamers, such as organosiloxane, polyether, grafting of silicon and ether, containing amines, imines and amides, which have the characteristics of faster defoaming speed, longer foam inhibition time, wider applicable medium range and even harsh medium environment such as high temperature, strong acid and strong base Can defoamer be used? It is specially designed for the food processing industry It is widely used in bean products, dairy industry, pharmaceutical industry, dairy industry, beverage industry, sugar industry, soybean protein extraction, soy sauce and vinegar brewing, cigarette holder adhesive and other food industries Therefore, food defoamer is edible and you can rest assured Defoamer has the advantages of fast defoaming speed, long time of foam inhibition and good dispersing effect; The physical and chemical properties are stable, do not react with the substances in the foaming system, and do not affect the product quality, which is very useful for the food processing industry Therefore, we should have a deeper understanding of defoamers and learn more about food safety knowledge, which will help us understand more about food additives Everyone is very concerned about food safety and can use them Food safety tester food safety Editor in charge: he xianrob
