What is E 631?

E 631 is a food additive that is commonly used in various processed foods to enhance flavor. It is also known as Disodium inosinate and is often used in conjunction with MSG (Monosodium Glutamate) to provide the umami taste.

Sources of E 631

E 631 can be derived from both animal and plant sources. It is commonly found in fish, meat, and mushrooms. However, it can also be produced synthetically using fermented sugar and tapioca starch.

Health Concerns

While E 631 is considered safe for consumption by regulatory bodies such as the FDA, some people may be sensitive to it. Individuals with gout or asthma may want to avoid foods containing E 631 as it can trigger symptoms in some cases.

Labeling

Food products that contain E 631 are required to list it on the ingredient label. Look for 'E 631' or 'Disodium inosinate' in the list of ingredients to identify its presence in the food.

Alternatives

If you prefer to avoid E 631 in your diet, look for products that use natural flavor enhancers like herbs, spices, and homemade broths. Experimenting with different seasonings can help you achieve delicious flavors without relying on additives like E 631.
