Octyl Gallate

International Numbering System (INS) for Food Additives: 311
Food additives Europe numbers: E311

Octyl gallate is a food excipient that functions primarily as an antioxidant and preservative [1]. Here's a closer look at its role in food processing:

• Antioxidant Properties: Octyl gallate helps prevent spoilage by delaying the oxidation of fats and oils in food products. Oxidation can lead to off-flavors and rancidity. By acting as an antioxidant, octyl gallate extends the shelf life of foods containing fats and oils, like nuts, vegetable oils, and some processed meats.
• Synergistic Effect: Octyl gallate can work synergistically with other common food antioxidants like BHA (butylated hydroxyanisole) and BHT (butylated hydroxytoluene) [1]. This means that the combination of these antioxidants provides a stronger protective effect against oxidation than any of them would individually.

Here are some additional points to keep in mind about octyl gallate:

• Generally Recognized as Safe (GRAS): In most countries, octyl gallate is generally recognized as safe (GRAS) for use in food by regulatory bodies [1]. However, permitted usage levels may vary by region.
• Limited Use: While approved for use, octyl gallate isn't as widely used as some other food antioxidants. This might be due to factors like cost, effectiveness compared to other options, or potential flavor interactions in certain foods.
• Dietary Concerns: Some people may have concerns about consuming octyl gallate, although research on its safety in humans is generally reassuring [2]. If you have any concerns, consulting a healthcare professional is always a good idea.
