Food Additives You Won't Find on the List
One of the most difficult aspects of determining the kosher status of a
processed food is knowing which additives, that may appear to be kosher
- may, in fact, because they are processed before they are added to the
food - are kosher. Any prepared ingredient does not have to list its constituents
on a label (e.g., when a canned food lists tomato sauce as one of its ingredients
it does not have to list the ingredients of the tomato sauce). Additionally,
there are certain foods and ingredients whose formulæ are, through a loophole
in the law, concidered industry standards and do not have to be listed.
Such items include (but are not limited to) ice cream, mayonnaise, vanilla
extract, almond extract, beer, liquor and wine (it is actually against the
law to list all the ingredients in liquor and wine!), soft drinks, etc.
