Kosher for Pesach
Kosher for Pesach for all
How do you know Natural Flavors does not contain a grain-based flavor not kosher for passover, or for that matter, a non kosher animal? Per FDA definition of Natural Flavors, it may contain animals
If a natural or artificial flavoring contains an animal product, there are specific labeling requirements that must be followed. According to the FDA regulations, if a flavoring contains any protein derived from a major food allergen, such as milk, eggs, fish, crustacean shellfish, tree nuts, wheat, peanuts, or soybeans, it must be declared on the label using the common or usual name of the food source from which the protein is derived.
For example, if a natural or artificial flavoring contains protein derived from milk, it must be listed on the label as “contains milk.” If the flavoring contains protein from multiple allergenic sources, all of the sources must be listed on the label.
If the flavoring contains any other animal-derived ingredient that does not fall under the category of a major food allergen, it is not required to be listed on the label by its animal source. Instead, it can be listed using a more general term, such as “animal-derived flavoring” or “animal-based flavoring.” However, if the use of such an ingredient in the flavoring could cause consumer deception or if the ingredient is used for its functional properties (i.e., as a thickener or emulsifier), then it must be specifically identified on the label.
In summary, if a natural or artificial flavoring contains an animal product, the label must declare the presence of any allergenic protein sources derived from animals, but for other animal-derived ingredients, more general terms may be used on the label.
