Antifoams are also known as "defoamers." These additives serve businesses across a number of industries by helping to maintain foam formation or stopping bubbles from occurring in production operations. The ingredients are insoluble in foaming mediums and spread rapidly across surfaces due to their low viscosity.

The need for antifoams becomes apparent when foam disturbs processing, filling or volume measurements or when the texture of the food product is negatively affected. The first solution to prevent foam is control of the processing but in some cases food manufacturers cannot do this without the addition of antifoam.

Different types of antifoams in the food industry

Prior to antifoam products being available on the market, natural antifoaming agents such as squeezed lemon juice and cooking oil could be included as ingredients to reduce foaming. A demand for a more well-rounded solution comes as a result of these two ingredients altering taste when used in higher volumes. Different categories of antifoams are available:

Oil-based foam control

Oil-based defoamers are ideal for intense foaming applications and reduction. They contain an oil carrier and do not mix well with water for optimum antifoaming characteristics. These antifoamers are insoluble in water and water-based solutions.

Silicon-based defoamers

Silicon-based antifoams feature a hydrophobic form of silica for remaining insoluble in water. Food manufacturers can utilize silicon-based antifoams in food preparation, water treatment, and more. These ingredients can also be found in non-aqueous foaming systems, including oil refining.

Antifoam applications in food industry

Defoamers cut back on material losses during food preparation and production. Antifoaming agents of the silicon-base variety are common within the food industry to meet customer expectations of products.

Food professionals see defoamers in the preparation of deep fried foods such as chicken nuggets, fries, and chips. The additives give food companies the opportunity to enhance methods for:

•Washing food products (vegetables)

•Distillation and evaporation
