| 摘要 |
The invention provides a cost-effective enzymatic process for the production of unsaturated FA esters of ascorbic acid, such as ascorbyl oleate or ascorbyl linoleate (E-304), in solvent-free system in which ascorbic acid esters of saturated FA, unsaturated free fatty acids and/or unsaturated fatty acid esters are used as feedstock. With this method pure products can even be achieved in a short response times. These products meet the needs of the industry by improving their solubility in oil and the increased antioxidant activity, especially in foods, cosmetics and medicine.
