Table 6.5 lists some common names, systematic names, and

EC numbers for some common food enzymes.

Enzyme classification and nomenclature are now standardized

procedures. Some journals already require that enzyme codes be

used in citing or naming enzymes. Other journals are following

the trend. It is expected that all enzymes will have enzyme codes

in new research articles as well as (one hopes) in new reference

books. However, for older literature, it is still difficult to identify

the enzyme codes. It is hoped that Tables 6.4 and 6.5 will be

useful as references.
