Propyl gallate in food: what it is
Chemical nature and function
You might wonder why propyl gallate in food helps keep food fresh. This compound is made from gallic acid and is part of a group called trihydroxybenzoic acids. Its structure has many hydroxyl groups. These groups let the molecule catch free radicals. Free radicals are unstable and can hurt fats and oils in food. When propyl gallate in food catches these free radicals, it stops them from causing damage.
Propyl gallate in food acts as an antioxidant. It keeps food safe by slowing down lipid oxidation. Lipid oxidation happens when fats and oils mix with oxygen. This can make food taste bad and smell strange. You might notice this in old chips or nuts that taste rancid. By stopping free radicals, propyl gallate in food helps food stay fresh longer.
Note:
Some research shows that certain marine bacteria and small water animals react to propyl gallate in food. This means the compound could affect the environment if not handled right.
Common foods with propyl gallate
You can find propyl gallate in food that has fats and oils. Food makers add it to stop spoilage and make food last longer. Here are some common types and examples:

Propyl gallate in food is important for keeping many foods safe and tasty. Knowing where it is and how it works can help you make better choices when shopping.
Propyl gallate safety
GRAS status and regulations
You might wonder how experts check if food additives are safe. In the United States, the FDA gives some additives a label called “Generally Recognized As Safe” or GRAS. This means scientists agree the additive is safe when used the right way. Propyl gallate in food has GRAS status in the U.S. The European Union also lets people use it as a food additive. There, it is called E310. Both places have strict rules about how much can be used.
Here is a table that shows the rules:
Region | Status | Notes |
|---|---|---|
United States | Generally Recognized As Safe (GRAS) | The FDA says it is safe if used within limits. |
European Union | Permitted as a food additive (E310) | Allowed in certain amounts based on safety studies. |
You may see E310 on food labels. This is the code for propyl gallate. Food safety groups set the highest amount you can eat to keep you safe:
E number for propyl gallate: E310
EFSA says you can have up to 0.5 mg per kg of body weight each day
JECFA says you can have 0 to 1.4 mg per kg of body weight
Agencies keep checking their rules to make sure food additives are still safe. For example, the FDA uses a new plan to decide which chemicals to review. They also have a system to check chemicals after they are in the market. This means they look at propyl gallate in food often and listen to scientists and the public. The FDA also updates its list of chemicals to review, including important additives.
Action | Description |
|---|---|
Modernized Prioritization Scheme | The FDA will share a plan for the public to comment on. It will show how they pick chemicals to review. |
Systematic Post-Market Review Process | The FDA will use a set way to check chemicals and listen to feedback. |
Important additives, like propyl gallate, will get faster reviews as part of new rules. |
International rules can change too. The European Union recently made new rules for propyl gallate (E310). Now, they do not allow some catalysts in making it. They also lowered the highest amounts for heavy metals like arsenic, mercury, and lead.
Food Additive | Changes Made |
|---|---|
Propyl gallate (E 310) | – Changed rules to stop some catalysts in making it. |
Tip:
Always look at food labels for E numbers or the additive name if you want to know what is in your food.
Typical intake and exposure
You might ask if the amount of propyl gallate in food is safe for you. Food safety groups like EFSA set a safe daily amount, called ADI, for this additive. The ADI is the amount you can eat every day for your whole life without harm.
EFSA says the ADI for propyl gallate is 0.5 mg per kg of body weight each day.
People eat less than this safe amount.
Scientists say the usual levels in food are not a problem.
Scientists agree that propyl gallate is safe at allowed levels. Experts also checked if it is safe for animals. For example, cats can have up to 71 mg per kg of food. The FEEDAP Panel uses new facts to make these choices.
Note:
Scientists and rule makers keep looking at new studies. If they find new dangers, they change the rules to keep you and your family safe.
