Is E304 (Ascorbyl palmitate) Halal?

Our assessment

Doubtful — depends on source

E304 (Ascorbyl palmitate) is a fat-soluble form of vitamin C whose palmitic-acid part can be plant- or animal-derived — so it is treated as doubtful (mushbooh) unless the source is known.

What is E304?

Ascorbyl palmitate is a fat-soluble antioxidant made by joining vitamin C (ascorbic acid) to palmitic acid. It protects oils and fats in food from going rancid.

Ascorbic acid is esterified with palmitic acid. The palmitic acid can come from palm or other vegetable oils, or from animal fat — the label rarely says which.

Why is it doubtful (mushbooh)?

E304's status depends on the source of its palmitic acid. When that comes from vegetable oil (commonly palm), it is halal; when it comes from animal fat, it is only permissible if the animal was halal. Because the source is usually unstated, it is treated as doubtful until confirmed. Most commercial ascorbyl palmitate uses vegetable-derived palmitic acid, but this should be verified rather than assumed.

How to verify a product in Singapore

  1. Ingredient-level guidance is not halal certification — check the complete product, not just this ingredient.
  2. Look for recognised halal certification, and check the finished product on the official MUIS HalalSG register.
  3. When the source or processing aids are unclear, contact the manufacturer.

In Singapore, verify the finished product on the MUIS HalalSG register. A certified product will have had the palmitic-acid source assessed; for an uncertified product, contact the manufacturer.
