Sorbitan esters E491–E495 are sorbitol plus fatty acids (stearate, tristearate, laurate, oleate, palmitate).

Possible source pathways

The finished molecule can be identical across feedstocks. The Halal ruling follows the pathway, not the code alone.

E491 Possible source pathways

  • plant Halal Typical Fatty acids from palm, soy, sunflower, coconut, or other vegetable oils.
  • animal Halal if verified The same esters can be split from tallow or lard. Pork or non-zabiha fat is haram; audited zabiha tallow is accepted after audit.
  • undisclosed Halal if verified Typical Most labels print only the E-number or US chemical name. Treat as mashbooh until a plant, vegan, or Halal claim settles the fat.

E-number database

How to verify

  1. Match E491–E495, INS 491–495, Span 20/40/60/65/80, or the long sorbitan names.
  2. Vegetarian/vegan or Halal marks settle the fat.
  3. These are the non-ethoxylated cousins of polysorbates (E432–E436).

Quick checks

  • E491 (sorbitan monostearate, Span 60) is common in instant dried yeast, cake mixes and whipped toppings.
  • A vegetarian, vegan or Halal mark settles which fat was used.
  • Polysorbates (E432–E436) are related and carry the same fat question.

What decides the answer

  • Plant-fat E491–E495, or vegetarian/vegan claim

    Halal

  • Halal-certified product

    Halal

  • Pork or non-zabiha fatty acid

Why this ruling

Sorbitan esters are made by joining sorbitol, a sugar alcohol, to a fatty acid. There are five in the EU list, sold under the trade name Span:[2][3]

Code Name Fatty acid
E491 Sorbitan monostearate (Span 60) Stearic
E492 Sorbitan tristearate (Span 65) Stearic
E493 Sorbitan monolaurate (Span 20) Lauric
E494 Sorbitan monooleate (Span 80) Oleic
E495 Sorbitan monopalmitate (Span 40) Palmitic

Codex uses the same numbers as INS 491–495.[5]

Where the question is

Sorbitol is made from glucose and is Halal. The fatty acid is the part that can come from palm, coconut or other vegetable oils, or from animal fat such as tallow. So the ruling follows it:

  • Vegetable fatty acids → Halal.
  • From a Halal-slaughtered animal → Halal.
  • From pork or non-Halal slaughter → not Halal.
  • Not stated → Halal if verified.

Certifier lists treat unsourced sorbitan esters the same way as E471.[6]

Where you will find them

  • Dried yeast – sorbitan monostearate coats instant and active dried yeast granules so they rehydrate evenly. It is often the only additive in a yeast sachet; see yeast.
  • Cake icings, fillings and whipped toppings.
  • Chocolate and compound coatings – E492 slows the white "bloom" on the surface.
  • Coffee whiteners and some sauces.

Settling it

A vegan or vegetarian claim on the pack settles it, as does a Halal certification. For yeast, many brands state that their emulsifier is plant-based, or answer the question by email. The ethoxylated relatives, the polysorbates (Tween), have their own page: see E433. For sorbitol itself, see sorbitol.

Frequently asked questions

Is the E491 in instant yeast made from pork fat?
That claim spread on social media, especially about instant yeast. In July 2016 Dubai Municipality's food safety department said laboratory tests found the yeast it examined free of pork fat, and that E491 (sorbitan monostearate) usually comes from a plant or animal source. So E491 is not pork by definition, but its fat source still varies by product: look for a Halal mark or a stated plant source.
Is Span 60 Halal?
Span 60 is sorbitan monostearate (E491). It is Halal when the stearic acid is from plants or from Halal-audited animal fat.
Is this the same as polysorbate 60?
No. Polysorbate 60 is E435, an ethoxylated cousin. Both can raise the same stearic-acid source question.
What is E492?
Sorbitan tristearate (Span 65). It is from the same family, with more stearic chains, and it helps stop chocolate from blooming.
Why is E491 in dried yeast?
It protects the yeast cells as they dry and helps them revive in dough. Check the yeast pack for a vegetarian or Halal mark.

Scholarly view

Sorbitan esters are the non-ethoxylated cousins of polysorbates. The Halal issue is the fatty acid. Unspecified E491 is mashbooh on the same pattern as E471.
