The technical conditions of combined extraction of pectin from grape peel and pomace were investigated and the quality of the ex- tracted pectin was evaluated. 0.05 mol/L dilute H2SO4 was used as extracting agent, the ratio of raw materials and liquid was 1:10(g:mL), pH value was 2.5, 1 h extraction was carried out twice with temperature at 80℃, and the best extraction effects could be achieved with product yield as 9.82 % and the content of galacturonic acid as 68.86 %. By the solvent method, the result showed that the extracted pectin had 4 indexes superior to the national standards and 2 indexes inferior to the national standards.
