The wet peeling process conditions and effect of chufa was studied. The peeling rate and mass loss rate were selected as indexes and the effect of the soaking solution concentration, soaking temperature and time on peeling effect was studied. The results showed that the optimal conditions of wet peeling process of chufa were that soaking solution concentration was 5%, at 95 ℃, for 6 min. Under the condition, chufa peeling rate was 94.8% and the mass loss rate was 15.8%. The quality of chufa oil was improved after being treated with wet peeling process compared with the one without being treated.
