The Dual Origin of E471
E471, the European food additive number for mono- and diglycerides of fatty acids, is a food emulsifier created through the reaction of glycerol with fatty acids. While the term 'fatty acids' might sound benign, their source determines whether the final product is plant-based or animal-based. This duality is the primary reason for the ingredient's controversy among certain dietary groups. The manufacturing process, called glycerolysis, does not alter the fundamental chemical identity of the mono- and diglycerides, meaning the end product is chemically identical whether it originates from a plant or an animal.
Animal-Based Sources
When derived from animal sources, E471 typically comes from rendered animal fats. The most common animal fats used include tallow (rendered beef fat) and lard (rendered pork fat). For those with dietary restrictions based on religion, such as Judaism and Islam, or ethical concerns, such as vegetarianism and veganism, E471 from animal fat is not an option. The process does not eliminate the animal origin, despite the transformation of the raw fats during manufacturing. Products like ice cream, margarine, and baked goods can all use animal-derived E471 to improve their texture and shelf life.
Plant-Based Sources
For many food manufacturers, using vegetable oils to produce E471 is a common and often more cost-effective alternative. Plant-based sources include a variety of oils such as soybean, palm, rapeseed, and sunflower oil. The use of palm oil, however, introduces its own set of ethical considerations, particularly concerning environmental sustainability. When a product uses only plant-based E471, it may be marked as 'suitable for vegetarians and vegans' or feature a specific certification. However, this labeling is not mandatory unless specifically regulated in a country.
Why the Source of E471 Isn't Always Clear
The primary reason for the uncertainty surrounding the source of E471 is that food labeling laws often don't require the specific origin of the fatty acids to be disclosed. The 'E471' or 'mono- and diglycerides of fatty acids' label is considered sufficient for regulatory purposes. This chemical designation is the same regardless of whether the fat used was from a plant or an animal. For consumers trying to make informed choices, this can be frustrating. A lack of specific labeling requires individuals to either contact the manufacturer directly or rely on product certifications to be certain.
How to Determine the Origin
If you have dietary restrictions, here are some steps you can take to determine the origin of E471 in a product:
- Look for certification logos: Check the packaging for vegan, vegetarian, halal, or kosher certification symbols. These labels indicate that the product's ingredients, including E471, meet specific standards.
- Read manufacturer statements: Some companies, especially those catering to dietary-conscious consumers, will state on their packaging or website that their emulsifiers are vegetable-based.
- Check the ingredients list for clues: If a product is clearly labeled 'vegan' or 'vegetarian', the E471 is likely plant-based. However, products without this labeling are uncertain.
- Contact the manufacturer: The most definitive way to know the source is to call or email the food manufacturer and ask for details about their E471 source.
E471: Vegan, Vegetarian, Halal, and Kosher Concerns
For individuals with specific dietary needs, E471 presents a potential hazard due to its indeterminate origin. For vegans and vegetarians, E471 derived from animal fat is unacceptable. For Muslims, E471 made from pork fat is haram (forbidden), while E471 from non-halal slaughtered animals is also impermissible. Similarly, for Jewish people, E471 derived from non-kosher animals or processed in a way that violates kosher law is prohibited. The chemical modification process does not necessarily resolve these religious concerns, as opinions vary on whether the transformation is sufficient to change the haram status of the final product. Given this ambiguity, many choose to avoid products containing E471 unless its vegetable origin is explicitly certified.

How E471 is Manufactured
E471 is manufactured through a process called glycerolysis, where triglycerides (fats and oils) are reacted with glycerol. This reaction breaks down the triglycerides into mono- and diglycerides. The raw materials—glycerol and fatty acids—are derived from either vegetable oils or animal fats. For instance, a manufacturer might use soybean oil to get plant-based fatty acids, or beef tallow to get animal-based ones. The resulting mixture is then purified and processed to create the E471 food additive, which is used for its emulsifying, stabilizing, and texture-improving properties in numerous foods.
Comparison of E471 Sources
| Feature | Plant-Based E471 | Animal-Based E471 |
|---|---|---|
| Source Material | Soybean oil, palm oil, rapeseed oil, sunflower oil | Beef tallow, pork lard |
| Dietary Suitability | Suitable for vegans, vegetarians, halal, and kosher diets (with certification) | Not suitable for vegans, vegetarians, or those requiring strict halal or kosher products |
| Ethical Concerns | Some sources, like palm oil, can have environmental impacts related to deforestation. | Raises ethical issues for animal welfare and religious observance |
| Market Labeling | May be explicitly labeled 'vegan' or 'plant-based'; otherwise, origin is uncertain. | Rarely labeled as such; usually listed simply as 'E471' or 'mono- and diglycerides'. |
| Certifications | Can receive certifications like Vegan Society, Halal, or Kosher. | Cannot receive vegan or strict halal/kosher certifications based on origin. |
Common Foods That May Contain E471
E471 is a versatile emulsifier used in a wide range of processed food products. Its functions include stabilizing emulsions (like oil and water in margarine), improving the texture of baked goods, and preventing ice crystal formation in frozen desserts. Products that might contain E471 include:
- Baked Goods: Breads, cakes, and pastries
- Dairy Alternatives: Vegan cheeses and ice creams that rely on non-animal emulsifiers
- Confectionery: Chocolates, caramels, and chewing gum
- Spreads and Sauces: Margarine, mayonnaise, and salad dressings
- Instant Mixes: Dessert mixes, cake mixes, and instant potatoes
Conclusion: Making Informed Dietary Choices
Because what animal does E471 come from is not always clear, conscious consumers must remain vigilant. The emulsifier's dual origin from either plant oils or animal fats means that relying solely on the ingredient list is insufficient for those with dietary restrictions based on ethical or religious beliefs. To ensure a product aligns with your diet, look for explicit vegan, halal, or kosher certifications on the packaging. When in doubt, contacting the manufacturer directly is the most reliable method for uncovering the true source of E471 in a food product. This diligent approach is the only way to navigate the complexities of modern food labeling and make truly informed choices about what you consume.
