E348

E348 is the European Union's designation for a food additive, specifically the antioxidant and flour treatment agent Ascorbyl Palmitate. Ascorbyl palmitate is an ester formed from ascorbic acid (Vitamin C) and palmitic acid, a saturated fatty acid. It is produced by chemical synthesis.

In food, Ascorbyl Palmitate functions as an antioxidant, meaning it helps to prevent the oxidation of fats and oils, thereby extending the shelf life of food products. It is particularly effective in preventing rancidity in fatty foods. It can also be used as a flour treatment agent, improving the texture and baking properties of dough.

The use of E348 is permitted in various food categories, including baked goods, cereals, fats and oils, and certain processed foods. Its typical usage levels are generally low, as it is effective in small quantities. Regulatory bodies like the European Food Safety Authority (EFSA) have evaluated its safety and established acceptable daily intake (ADI) levels. Ascorbyl palmitate is considered safe for consumption within these limits. It is also recognized by the US Food and Drug Administration (FDA) as Generally Recognized As Safe (GRAS) for certain uses.
