METHOD FOR SYNCHRONOUSLY EXTRACTING LYCOPENE AND CITRULLINE FROM WATERMELON

摘要

The present invention relates to the technical field of natural substance extracting, and disclosed is a method for synchronously extracting lycopene and citrulline from a watermelon. The method for synchronously extracting lycopene and citrulline from the watermelon of the present invention comprises: separating the rind and the pulp of the watermelon, preprocessing the rind, and using the preprocessed rind to extract the citrulline; subjecting the pulp to biological enzymolysis and filtering, centrifuging a filtrate, using a precipitate and a filter residue obtained after the centrifuging to extract the lycopene, and using a supernate obtained after the centrifuging to extract the citrulline. By using the method for synchronously extracting lycopene and citrulline from the watermelon of the present invention, about 0.5 kg of lycopene (6% content) and more than 1.2 kg of citrulline which are worthy of nearly ten thousand yuan can be extracted from each ton of imperfect watermelons, the economic benefit of each ton of watermelons can be increased by more than 5000 yuan after extraction costs are deducted, and the method is high in economic benefits.
