As Flavor enhancers are substances that are suitable for enhancing the perception of the taste or smell of a food. Most of the flavor enhancers are food additives. So far there is no known flavor enhancer that can enhance all flavors.
A secondary condition is often mentioned that such a substance does not contribute to the taste itself, i.e. that it should be tasteless. The common substances mentioned under A. do not meet this requirement. Alapyiridain (see B.), on the other hand, is practically tasteless.

A. Flavor enhancers based on glutamic acid, inosinic acid and guanylic acid

The most important additives for flavor enhancement under food law are labeled with E numbers E 620 to E 640. Several of them are glutamic acid, guanylic acid and inosinic acid as well as chemical compounds thereof. They are often used in combinations, with mixtures of 95% of a glutamate (e.g. monosodium glutamate as the best known flavor enhancer) with inosinates and guanylates being particularly effective for enhancing "hearty" and salty dishes. Sweet, sour or bitter dishes, on the other hand, are not enhanced in terms of taste. These substances and their mixtures are also not tasteless but have a distinct umami taste.

Flavor enhancers approved as food additives

The use of flavor enhancers of this type is controversial for two main reasons:

  • Why should a food not taste the way it originally tasted? The industry has an answer to this: If a longer shelf life is sought, the declining taste must be "compensated for". There is another reason for prepared foods: Savings can be made on flavoring ingredients if their lower quantity or quality is compensated for by enhancing their taste. The responsible consumer is in demand here; he can take a position on this and adjust his purchasing behavior accordingly.
  • Do flavor enhancers have side effects, are they possibly health hazards? According to overwhelming scientific conviction, there is no general danger. But there are certainly people who are sensitive to these substances. Again, it is important to be informed as a consumer and possibly to avoid foods with such additives yourself.

B. Other flavor enhancers

The compound alapyridain from sugar and the amino acids alanine was identified in 2003 as a taste-enhancing substance. It arises, among other things, in the production of a strong beef bouillon and can be extracted from it. Alapyridain itself is almost tasteless and can enhance the taste of sweet, salty and umami-tasting dishes, but not sour and bitter ones. There is currently (2009) no industrial use.

Annotation: The amplifiers mentioned under A. cannot do that either, they can only be used for hearty, salty preparations and also bring their characteristic umami taste.

C. Other

It is well known that sugar "enhances" the taste of strawberries 🛒 and many other fruits. This is not a matter of enhancing the taste; rather, the sweetness, together with fruit acids and other fruit components, creates a taste accord that is more pleasing than the taste of the pure fruit. Adding small amounts of salt to sweet preparations works in a similar way. Fat can release or carry flavors that are not soluble in water. This then appears like an enhancement of the taste.

In the end: If you can enhance taste, it would be strange not to be able to weaken it too. Usually this is of no practical importance. One exception: a sour-tasting liquid is less acidic if potassium ions are present. This is important with wine.
