Alpha-Tocopherol (E307)

Purpose and Function

Alpha-Tocopherol (E307) is used in the food industry as an antioxidant. It helps prevent the oxidation of fats and oils, thereby extending the shelf life of various food products and preserving their quality. Although it is a synthetic form, it mimics the properties of natural vitamin E and is widely used for its antioxidant benefits. Common applications include:

• Oils and fats: Added to cooking oils, margarine, and butter to prevent rancidity.
• Baked goods: Helps maintain freshness in pastries, cakes, and other fat-containing products.
• Snack foods: Used in fatty snacks like chips and nuts to delay oxidation.
• Meat products: Preserves color and prevents spoilage in processed meats and sausages.
• Dietary supplements: Found in vitamin E supplements, especially those containing synthetic vitamin E.

Alpha-Tocopherol (E307) is effective in protecting food products from oxidation, making it a popular choice in food preservation.

Potential Risks and Side Effects

Alpha-Tocopherol (E307) is generally considered safe when used within regulated limits, but some considerations include:

• High intake of supplements: While dietary intake is safe, excessive consumption of synthetic vitamin E supplements can lead to adverse effects such as nausea, fatigue, or bleeding issues.
• Difference in bioavailability: Synthetic alpha-tocopherol (dl-alpha-tocopherol) may not be as readily absorbed or utilized by the body as natural vitamin E (d-alpha-tocopherol).
• Regulatory approval: E307 is approved for use in many countries, including the European Union and the United States, where it is considered safe for use as an antioxidant in food products.

Overall, it is regarded as a safe and effective antioxidant, especially for preserving fats and oils.
