Abstract
The extraction technology of pectin by Microwave-assisted of Extraction,decolor extraction liquid,ethanol precipitation technique from apple pomace was studied in this paper.According to orthogonal method L9(34),the optimal technology for the extraction at 250W power of microwave radiation was obtained: material-liquid ratio 1:40g/mL,pH value 1.3,time 35min and temperature 65℃.Under this condition,the extraction ratio of pectin in apple pomace was 10.61%.The result was good.
