Abstract： In this study，soluble dietary fiber （SDF） is successfully extracted from Cabernet Sauvignon grape skin pomace in Yanqi Basin of Xinjiang using microwave-assisted acid method，and the optimal process parameters during extraction are explored. The research focus is concentrated on evaluating the yield of SDF，and through analysis of four key variables such as citric acid mass fraction，solid-liquid ratio， microwave power and microwave time，the effect of these parameters on the yield of SDF is explored in depth. On the basis of single factor test，response surface analysis method is used to finely adjust and optimize these conditions，and the optimal extraction process parameters are finally determined to be solid-liquid ratio of 1：24.97 ，microwave power of 22o.56 W and microwave time of 60.24s ，Under these optimized conditions，the yield of SDF in grape skin pomace reaches 22.17% . In addition，the swelling force，water holding capacity and oil holding capacity of SDF are measured，and its microstructure is analyzed by scanning electron microscopy （SEM）. The research results have not only provided a powerful theoretical basis for the high-value utilization of grape skin pomace，but also opened up new avenues for the deep processing of related industries and the comprehensive utilization of resources.
