INDEXING SCHEME RELATING TO FOODS, FOODSTUFFS OR NON-ALCOHOLIC BEVERAGES
NOTE
-
This subclass constitutes an internal scheme for indexing only.

A23V 2002/00
Food compositions, function of food ingredients or processes for food or foodstuffs
NOTE
-
Indexing codes of main groups A23V 2200/00 , A23V 2250/00 and A23V 2300/00 are used in combination with the base symbol A23V 2002/00 to indicate the composition, function of ingredients or processes.


The indexing codes of this group are used in combination with the ingredients compositions codes
