Additive E202 or potassium sorbate: health effects
The modern food industry, unfortunately,can not do without dyes, fragrances and preservatives. According to WHO, they are all safe and can not cause serious harm to health. However, some of them are still recommended to eat in limited quantities, while others are not. One of the most harmless is the addition of E202. The impact on the human body, according to the same WHO, is minimal. However, some scientists question this truth. But what are they so embarrassed about it?
What is the E202?
Additive E202 or potassium sorbate is a natural preservative derived from sorbic acid. From the chemical point of view, it is simply an acid salt and has the formula C6H7KO2. It is obtained from the bones and the juice of plants(for example, mountain ash), are less often synthesized. For the first time this was done in the second half of the 19th century. But only in the 20th century were its antimicrobial properties discovered. A little later, potassium sorbate was commercially produced.
Influence on health was little studied inthe difference from the properties of this food additive. Thus, it is known for certain that the addition of E202 slows the growth of mold fungi and yeast, so it can be used to prolong the shelf life of cheese and sausages. In addition, he has neither taste nor smell. This makes it possible to add it as a preservative in various confectionery desserts, vegetable and fruit preserves and juices. Since it behaves perfectly even in an acidic environment, potassium sorbate can often be found in spicy and spicy Asian sauces.
But basically, of course, he got his ownpopularity in the food industry, thanks to another property. E202 is an additive that dissolves well in water. So, in 1 liter of liquid it can be up to 138 grams. This is much more than is required for the preservation of products.
Where is it used?
Speaking about potassium sorbate, it is possible with confidencesay that this is one of the most popular food additives. So, it is almost always added in the industrial canning of vegetables and fruits. And these are all kinds of pickles, marinades, jams, compotes and juices. This prevents the appearance of mold in them, and thus prolongs the shelf life. For every 100 kg of the finished product will not be more than 100-200 grams. It is believed that in this amount, potassium sorbate has no effect on health.
It is also almost always present in theoil-fat products. And this is margarine, mayonnaise and all sorts of cheeses. In popular hot sauces (mustard, ketchup, soybean and others), an E202 supplement can also be used. Usually it is not more than 100 grams in 100 kilograms of the product. And, of course, it is a part of the majority of smoked products, canned fish and non-alcoholic carbonated drinks and wines. Less commonly, potassium sorbate is used for processing the surface of rye bread, as well as food packaging.
Is there any harm?
On the one hand, WHO says that such aa food additive, like potassium sorbate, has no effect on health within acceptable limits. By the way, it should not be more than 0.2% of the total weight of the finished product. On the other hand, many scientists argue that the E202 supplement has not been sufficiently studied and there are cases of food poisoning with products with it. Who is right, after all?
It has already been proved that potassium sorbate is completelyis absorbed by the human body, disintegrating into the intestines into its components. It is with this fact that its wide application is connected. Е202 is allowed as an additive in most countries: the USA, Canada, Europe, Russia and throughout the post-Soviet space. However, in some cases, potassium sorbate can cause an allergic reaction, manifested as redness and itchy skin. In the rest, this food supplement can be considered absolutely harmless.
To be or not to be?
However, many today are concerned about the presence of foodadditives with the prefix "E". It is important to understand that this is just a classification. What will the potassium sorbate effect on health, still depends on many other factors. Including what is generally eaten and what kind of lifestyle people lead.
