Mono- and diglycerides of fatty acids (E471) may be halal or haram depending on their source. They can be derived from plant oils (halal) or from animal fats — including porcine (haram) or non-halal-slaughtered bovine sources (also haram). Because current food labelling regulations do not require manufacturers to specify the source, E471 is classified as mashbooh (doubtful) unless the product carries halal certification.
Mono- and diglycerides of fatty acids (E471) are emulsifiers — substances that help oil and water mix together. Chemically, they are partial glycerides: glycerol molecules with one (mono-) or two (di-) fatty acid chains attached, rather than the three chains found in a complete triglyceride (fat).
In food manufacturing, E471 is used to:
E471 is one of the most widely used food additives in the world, appearing in bread, biscuits, margarine, ice cream, chocolate, instant mashed potato, peanut butter, and many other products.
Mono- and diglycerides can be produced from several sources:
The critical issue is that food labels in most jurisdictions (including the EU, UK, USA, and Australia) do not require the source to be disclosed. "Mono- and diglycerides of fatty acids" or "E471" tells you nothing about whether it came from soy, palm, beef, or pork.
JAKIM treats E471 as mashbooh (doubtful) unless the source is verified. Products seeking JAKIM certification must provide documentation confirming the source of E471 is plant-derived or from halal-slaughtered animals. In practice, most JAKIM-certified products use plant-derived emulsifiers.
Indonesia's halal authority requires source documentation for all emulsifiers. Since October 2024, Indonesia's mandatory halal certification law requires that all food products sold in Indonesia carry a halal certificate — meaning manufacturers selling into the Indonesian market must verify and disclose the source of E471 to obtain certification.
UK and European halal certifiers generally classify E471 from plant sources as halal and E471 from porcine sources as haram. Products must have source documentation to achieve certification. Without certification, E471 on a European product should be treated as doubtful.
The Islamic Food and Nutrition Council of America applies the same standard: source documentation is required. They note that in North America, the majority of commercially produced E471 is palm- or soy-derived, but this cannot be assumed without certification.
If a product contains E471 and you want to confirm its halal status, follow these steps:
These everyday products commonly contain mono- and diglycerides — always check for halal certification if purchasing the mainstream (non-certified) version:
No. E471 from plant oils is halal. The issue is that labels do not specify the source, making it impossible to determine halal status without certification or direct confirmation from the manufacturer.
Yes. E471 is the European Union food additive code for mono- and diglycerides of fatty acids. The terms "mono-diglycerides," "monoglycerides and diglycerides," "glycerol monostearate," and "E471" all refer to the same class of emulsifier.
Vegetarian certification (as opposed to vegan) may still permit dairy- or egg-derived ingredients but typically excludes porcine and bovine-derived ingredients. A vegetarian label is a reasonable indicator that E471 is plant-derived, but it is not as definitive as a vegan or halal certification.

Certification & Standards
Conventional gelatin is one of the most widely used ingredients in food, pharmaceuticals, and cosmetics — and one of the most problematic for Muslim consumers. This guide covers every major halal gelatin alternative: what it is, where it comes from, and how manufacturers are putting it to work.
Certification & Standards
Both halal and kosher certification serve religious dietary laws, but the standards differ in significant ways. For food manufacturers and exporters, understanding these differences — and the commercial case for dual certification — can open two of the world's largest religious consumer markets simultaneously.
Certification & Standards
The Emirates Authority for Standardization and Metrology (ESMA) sets the halal standard for the UAE market. For any food, beverage, or consumer goods exporter targeting the UAE, understanding UAE.S 2055-1 and which foreign certifiers are on the ESMA acceptance list is non-negotiable.
