- Our advice
- Read the whole food label and consider how often you eat the product. A name or E number does not tell you the amount, and an ingredient rating cannot assess the entire food.
What it is
Propyl gallate is a synthetic antioxidant derived from gallic acid, used in small amounts to prevent fats and oils in food from becoming rancid. It is often combined with other antioxidants like BHA or BHT. Some animal studies have raised questions about high-dose effects, and EFSA has set an acceptable daily intake, but typical dietary exposure from food is well below levels of concern.
Also appears on labels as: E310, E 310, E-310, Propyl Gallate, Propyl 3,4,5-trihydroxybenzoate, Gallate of Propyl, n-Propyl Gallate, Propyl Ester of Gallic Acid, PG, INS 310, Food Additive E310, Antioxidant E310.

Research & body effects
Health notes from our ingredient record
- High-dose animal studies have shown effects on the gastrointestinal tract and blood; relevance to typical human dietary intake is limited.
- People with known sensitivity to gallates may experience contact or GI reactions.
- Regulated with an acceptable daily intake by EFSA and FDA; typical food-additive use is within these limits.

Country rules
Country checks for E310
Permission depends on the market, type of food, amount and conditions. A scientific opinion or an E-number alone does not establish a legal use. These checks are separate from the stored EatMatrix rating.

| European Union | Regulation (EC) 1333/2008, Annex II Part B, version , contains the exact code E310: Propyl gallate. Listing alone does not allow every food use. Part E food categories, limits, specifications and applicable later acts still need a product-specific check. Source read: . |

Food uses, limits and exceptionsThe limit is based on fat or oil The cited provision describes a maximum total antioxidant content of 0.02% of the food’s fat or oil, including volatile oils, under good manufacturing practice. This is not 0.02% of the whole food and not a separate 0.02% allowance for every antioxidant in a mixture. Other food-specific provisions and specifications still matter. EatMatrix’s reading: a legal use condition answers where and how an ingredient may be used. It is not a test of your product, a personal safe intake or a claim that the ingredient benefits your body. Match the named substance, food and amount. Other federal provisions, food standards, state rules and later changes may also apply; this is a selected source review, not a complete product-compliance decision. |
