I was wondering whether if the Betty Crocker cake mix and frosting was halal or not? The ingredients include mono- and diglycerides which might be derived from haram meat.
MuslimConsumerGroup.com classifies Betty Crocker cake mixes in various ways listed below.
The ingredient to be concerned about is Propylene Glycol Mono and Diesters of Fatty Acids which occurs in all three of the packages below. I believe this refers to ingredient E477.
In this case, it's suitable if derived from plants and not if derive from animals. The ruling would be derived in the same way as for E473 by AskImam, who write: it is best to avoid these products.
Super Moist Part Rainbow Cake Mix (reason: Due to presence of Confectionary Glaze)
It's not clear to me what is haram in this product (if anything).
and there are two families of conditionally halal mixes:
Supper Moist Chocolate Fudge, German Chocolate, Devil Food, Lemon Strawberry Cake Mixes
One example is:
Dark Chocolate, Ultimate Food, Milk Chocolate, Peanut Butter Cake Mixes
where the condition is "Halal if no alcohol is used in flavor."
It's hard to identify alcohol in the ingredients of these products; it's likely the amount of alcohol is minuscule (and is incapable of intoxicating in large quantities).
