Abstract:

A new preparation technology of pectin from apple pomace without ethanol-ion exchange method was proposed in this study. The optimized extracting conditions were determined by single-factor and orthogonal test with pectin yield as value index, while the optimized processing parameters and the choice of resin in removing impurities by ion exchange were discussed with transmittance and pectin yield as value indexes. The results showed that anion resin-D290 and cation resin-D061 are the best choice and the optimal rate is 1 BV/h for the column process. This new method overcomes the disadvantage of the traditional preparation technology by using mass ethanol with the better main indexes of products.

Key words: ion exchange method, pectin, apple pomace
