Maintaining or eliminating foam formation

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 controlling the processing. However, 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 were included to reduce foaming. These two ingredients altered taste when used in higher volumes. Despite the use of these antifoams, there was an increasing demand for a well-rounded solution.

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 utilize silicon-based antifoams in food preparation, water treatment, and more. These ingredients can also be found in non-aqueous foaming systems such as oil refining.

Defoamers in real-life applications

Defoamers reduce 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:

  • Crystallization
  • Distillation and evaporation
  • Extraction
  • Packaging
  • Purification
  • Washing food products (vegetables)
