| Abstract: | Apple pomace was used as material in this experiment to extract pectin by microwave radiation.The apple pomace was hydrolysed by hydrochloric acid(HCl) and pectin was precipitate by aluminum sulfated Al 2(SO 4) 3].The influence of radiation temperature,radiation times,pH value,the ratio of liquid,raw material,and the amount of aluminum sulfate on the production rate ware studied.The orthogonal experiment was employed to determine the optimum technological condition.Ash content,loss on drying,total galacturonic acid content,methoxy content molecule weight of voscosity of the product were analysed on this paper. |
