Process for the preparation of hydroxylated lecithin from crude soybean lecithin
First Claim
1. A process for preparation of hydroxylated lecithin from soybean lecithin, which comprises treating said soybean lecithin with from about 1 to 4% by weight of a 30% hydrogen peroxide solution based on the weight of lecithin and from about 12 to 18% by weight of a 75% lactic acid solution based on the weight of lecithin while subjecting the mixture of lecithin, hydrogen peroxide, and lactic acid to microwave irradiation at a power of from about 300 to 600 W at a temperature of from about 50 to 70°
- C. for a period of from about 5 to 60 minutes to obtain the desired product.
