E Numbers Not Suitable for Vegetarians

If you’re a vegetarian then you’ll need to consider E numbers if you’re buying and eating processed foods. Not all E numbers are suitable for a vegetarian diet due to where they’re sourced from.

The issue of whether E numbers are suitable for vegetarians or not sadly isn’t always clear-cut. This is because some E numbers can be obtained from either plant or animal sources. An example of this is E306 (tocopherol), which can be obtained from plant fat, therefore making it suitable for vegetarians. But it’s also possible for it to be derived from pork fat, which would be unsuitable for vegetarians.

Unfortunately for consumers, manufacturers don’t always make it clear on packaging exactly where they’ve obtained some E numbers from. If the packet carries the wording, “Suitable for vegetarians,” then the chances are that the ingredients have all come from plant sources. However, if you’re following a strict vegetarian diet and want to be 100% sure or the packaging doesn’t specify whether it’s suitable for vegetarians, then the best bet is to contact the manufacturer and ask for clarification. Contact details should be on the packaging of products and you could write, phone or email.

E Numbers to Avoid

E120 Cochineal:Cochineal is used as a food colouring in products such as drinks, biscuits, sweets, desserts and sauces. As it’s derived from the outer shell of a crushed cactus insect, it’s very much off-limits for vegetarians.

E Numbers to be Wary Of

As mentioned earlier, there are a lot of E numbers that can be derived from both animal and plant sources. The following numbers are examples of E numbers that can be vegetarian and non-vegetarian and that it’s therefore worth being wary of until you can determine their exact origin.

It’s important to note that ingredients of products do change, so a processed food that you were not able to eat in the past may become suitable for you as a vegetarian at a later stage if the offending E number is removed or replaced. Likewise, things can change in the other direction too, with manufacturers suddenly adding different E numbers to favourite foods so they suddenly become unsuitable for your dietary requirements.

One high profile case that illustrates how this can happen with a change in ingredients (not an E number) was Masterfoods, who announced they were going to change the ingredients in Mars bars and use animal products instead of vegetarian sources. After a massive outcry, they backtracked on their idea and decided to leave the recipe as it always had been.

Due to potential changes in the ingredients of processed foods, it’s a good idea to keep up-to-date by studying food labels as much as possible.
