Abstract
The invention relates to a microwave assisted process for the preparation of hydroxylated lecithin from soybean lecithin comprising hydroxylating crude soybean lecithin by using hydrogen peroxide and lactic acid as hydroxylating agent through microwave irradiation.
Claims5
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.
