Enzymes: the green key to aspartame

摘要

Whilst the flavour and fragrance industry has long relied on chemical processes to manufacture its products, enzymes from microorganisms can equally be used to provide many of these products in reactions known as biotransformations. The potential benefits of using this 'green' Technology, both to replace current chemical processes and also in novel productions, are enormous. Enzymes are able to operate under much milder conditions than most chemical catalysts - requiring neither extremes of pH nor of temperature. They are also very specific in their action, creating fewer unwanted by-products than chemical catalysts and thereby aiding purification.
