Delta Tocopherol

International Numbering System (INS) for Food Additives: 309

Food additives Europe numbers: E309

Delta-tocopherol is an interesting case in the world of food excipients. Here's a breakdown of its properties and use:

Type of Tocopherol:

• Delta-tocopherol is one of the four forms of vitamin E (tocopherols). The most common form used in supplements and fortified foods is alpha-tocopherol.

Functions in Food:

• Delta-tocopherol itself doesn't have a significant functional role as a food excipient. It doesn't possess strong thickening, gelling, or other technical properties typically sought after in excipients.

Potential Benefits:

• However, delta-tocopherol does have some potential benefits when present in food:
  • Antioxidant: Like other forms of vitamin E, delta-tocopherol has some antioxidant properties that may help delay spoilage of fats and oils in food.
  • Synergy with Alpha-Tocopherol: Some studies suggest delta-tocopherol may work synergistically with alpha-tocopherol, potentially enhancing the overall vitamin E activity in the body.

Use in Food Fortification:

• Delta-tocopherol might be present in some food products fortified with vitamin E.
• Since natural vitamin E sources often contain a mix of tocopherols, including delta-tocopherol, adding vitamin E from natural sources like mixed tocopherols concentrates can introduce some delta-tocopherol into the food.

Regulations:

• Delta-tocopherol itself isn't typically listed as a direct food additive with its own regulations.
• However, regulations for adding vitamin E to foods would apply if delta-tocopherol is present as part of a mixed tocopherol concentrate used for fortification.

Summary:

Delta-tocopherol isn't a common food excipient with specific technical functionalities. However, it may be present in some foods due to its natural occurrence in vitamin E sources used for fortification and might offer some antioxidant benefits.
