Study on extracting pectin from kiwifruit peel by the way of salting out

A research is conducted on the technological conditions of extracting pectin from fresh kiwifruit peel by salting-out.Experimental results show that when the pH value of the extracting solvent reaching 2,the operating temperaure as high as 90℃ and using aluminium sulfate as settlement after 70 minutes,the total yield of pectin is(higher than)4%.Compared with the way of alcohol,the way of salting out has advantages of lower cost and higher yield.
