In order to deeply investigate the technology of pectin extraction,pectin samples were extracted from apple pomace with hydrochloric acid and two enzymes(cellulase and bemicellulase).

Apple pomaces were pretreated by blanching and drying;extracting solvents were chosen for phenolics from apple pomace.

The cDNA-AFLP method was used to analyze the gene expression characteristics between shading and natural light condition in apple peel, and then the different expression genes were separated preliminarily.
