| Abstract: | [Objective] The research was to discuss techniques of extracting pectin from apple pomace suitable for industrialized production.[Method] With same apple pomace as raw materials,effects of salting-out method and alcohol precipitation method were studied respectively.[Result] The results showed that alcohol precipitation method got higher pectin yield,higher purity,good color and superior quality.Optimum conditions of alcohol precipitation method extraction were: the solution pH extracted by acid 1.5,solid-to-liquid ratio 1∶ 14 and extraction time 1.5 h.The pectin yield of salting-out method was 6.14%.[Conclusion] Alcohol precipitation method was suitable for industrial extracting pectin from apple pomace. |
| Keywords: | Apple pomace Pectin Extraction Salting-out method Alcohol precipitation method |
