| Abstract: | Pectin was extracted from orange peel by three different methods.The effects of pectin concentration,glycerol concentration and modified starch on the properties of pectin film were investigated and optimal process was studied.The results showed that the total pectin extraction efficiency is 10.35% by the tartaric acid hydrolysis and salting-out method.Finally,the results indicate the effects of glycerol concentration,pectin concentration,and modified starch addition on intensity of tension of the pectin fi... |
