Title: Study on Technology of Extracting Pectin from Apple Pomace
Abstract: Taking apple pomace as material,orthogonal experiment was adopted based on single factor experiment,the effect of different solid-to-liquid ratio,pH value,particle diameters,temperature and time on extraction of petin from apple pomace were studied and the ethanol precipitation was used.The results showed that the difference of acids on extraction technology of pectin was not obvious and nitric acid was selected.The optimal extraction parameters of pectin was:solid to liquid ratio 1∶30g/mL,pH value 1.3,particle diameter 60,extraction temperature 90℃ and extraction time 120minutes.
