Peracetic acid is one of the most widely used compounds in the food industry, although it has also many other uses. In today’s post we want to talk to you about what it is and what it is commonly used for.

Disinfectant in food

Peracetic acid is recorded under the formula CH3CO3H, which is produced by the reaction of acetic acid with hydrogen peroxide and is known by the acronym PAA. Its main use is in the food industry as a disinfectant, as part of food and drink cleaning protocols.

It is an acid with an oxidising capacity, which makes it very effective as a biocide. This is why it is commonly used in food factories. It is used to keep aerobic and anaerobic bacteria and their spores at bay, against yeasts and moulds and also against various viruses.

Peracetic acid is used at different levels as a disinfectant. To begin with, it is used to disinfect tanks, pipes or mixers through which food passes. It is also present in the packaging process, to sanitize containers and sealing systems where food is stored for its later distribution.

Food must go through its own disinfection process before being prepared for sale. The vegetables are washed in water to reduce the microbial load. Peracetic acid should be added to this liquid during some time, replacing chlorine. The reason for the change is that in small amounts it is safe and more effective as a biocide. In addition, peracetic acid improves the food preservation properties.

As we mentioned, the main use of peracetic acid is in the food industry, but it is also used in other sectors. This is the case of agriculture, livestock or health, where its disinfectant powers are also highly valued.
