Is Riboflavin / Lactofavin (E101) Halal?

Riboflavin (vitamin B2) is produced by fermentation using yeasts or bacteria. MUIS lists it as doubtful because the growth medium and processing aids can include animal-derived materials and the E-number does not identify the producer. Riboflavin from the major manufacturers is commonly halal-certified.

Riboflavin (vitamin B2) is a yellow-orange pigment that doubles as a colourant and an essential B-vitamin. It is most commonly produced by microbial fermentation using yeasts or bacteria, though it can also be chemically synthesised.
