ASSALAM O ALAIKUM,
I SHOULD LIKE TO ASKED THAT COULD WE USED R-40 ( E-129 ) IN ANY WAYS LIKE SPICES OR DESSERTS MIX ?
In the Name of Allah, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.
Allura Red AC (E- 129)is a red azo dye that goes by several names including: Allura Red, Food Red 17, C.I. 16035, FD&C Red 40, 2-naphthalenesulfonic acid, 6-hydroxy-5-((2-methoxy-5-methyl-4-sulfophenyl)azo)-, disodium salt, and disodium 6-hydroxy-5-((2-methoxy-5-methyl-4-sulfophenyl)azo)-2-naphthalenesulfonate. It is used as a food dye and has the E number E129.
E-129 is a synthetic chemical not derived from any animal by-products, etc, therefore such an ingredient would be Halal and permissible to consume.
And Allah Ta’āla Knows Best
