Study on Microwave - Assisted Extraction of the Yellow Pigment from Orange Peel

Abstract

The article is about extracting the yellow pigment from orange peel with the aid of microwave.It mainly studies the effect of concentration of ethanol,the ratio of material and solution,microwave time,microwave power on the extraction percent of yellow pigment .The Orthogonal experiment shows that the order of factors which influence the extraction rate are microwave time,microwave power and mass concentration of ethanol. The optimized process conditions are mass concentration of ethanol as 85%,the ratio of material and solution as 1:16g/mL,microwave time as 8 minutes,microwave power as 200W,the extraction percent of yellow pigment can be 8.59%.
