Food preservatives: what to watch out for?

Preservatives are substances that inhibit the development of microorganisms in food.Their action prevents the appearance of mold, unpleasant taste and smell, the proliferation of microbes and the formation of toxins. Products in the production or processing of which preservatives were used are stored for a long time. This explains the fact that it is profitable for manufacturers to use these substances in industry.

Many preservatives themselves are not dangerous to humans, but when interacting with each other can become toxic and accumulate in the body.
