Abstract

The invention belongs to the field of food additives, and particularly relates to a defoaming agent for food and a preparation method of the defoaming agent. The defoaming agent is prepared from 15%-22% of polysiloxane, 3%-10% of polyether-modified silicone oil, 6%-12% of hydrophobic white carbon black, 3%-5% of an emulsifying agent, 3%-6% of a thickening agent and 30%-70% of water, wherein polysiloxane is prepared from dimethicone I with the viscosity of 0.1-0.5 pa.s, dimethicone II with the viscosity of 50-100 pa.s and hydroxyl silicone oil according to the weight ratio of 1:(0.6-0.8):(0.3-0.5). The defoaming agent for the food has the advantages of being high in defoaming and foam inhibiting capacity, good in stability and the like and is safe, free of toxicity, easy to prepare, low in production cost and suitable for usage and application.

Description

technical field [0001] The invention belongs to the field of food additives, in particular to a defoamer for food. Background technique [0002] Defoamer is a chemical agent with chemical and interfacial chemical defoaming effect. It has the characteristics of low surface tension and high surface activity. It uses the mechanism of local surface tension reduction or destruction of membrane elasticity to achieve foam breaking, foam suppression, and defoaming. . During food processing, such as fermentation, stirring, boiling, concentration, etc., a large amount of foam will be generated. Excessive foam will reduce the filling coefficient of the equipment, cause liquid to stick to the exhaust pipe, cause loss of raw materials, and reduce bacteria. The acid-producing ability of the species can even make the operation impossible, and the addition of the defoamer can burst the foam. [0003] In the prior art, the defoaming agent has a single defoaming component, such as mainly us...
