Processing Technology of Microwave-assisted Salting Out Method Extracting Pectin From Fuchuan Navel Orange Peel

PAN Baiming;HE Caimei;LIANG Changxiang;TANG Shiying;Department of Food and Bioengineering,Hezhou University;  
Using Fuchuan navel orange peel as test material,the pectin was extracted by microwave assisted salting out method.The effects of microwave power,microwave time,solvent-solid ratio and Al_2(SO_4)_3 usage on pection ectraction were studied using single factor and orthogonal tests.Theresults showed that the microwave time was 5 minutes,optimum pectin microwave power was 400 W,solvent-solid ratio was 8∶1 mL·g~(-1) and Al_2(SO_4)_3 usage was 0.7 g,and the extractive yield of the pectin in navel orange peel was 22.33%.The extraction technology of pectin from Fuchuan navel orange peel prepared by microwave assisted salting out method could provide necessary technical support for industrial production.
