Abstract: The control effect of several kinds of natural antioxidants on VC loss in the process of strawberry washing and pulping was studied in this paper.Meanwhile they were compared with the effect of EDTA which has been freguently used in food processing.The results showed that 0.015% PA (Phytic Acid) could effectively control the VC loss in strawberry prolessing VC preservation yield has reached 91.62% in washing and 70.19% in pulping. Mixed with 0.015% natural antioxidants,VC preservation yield could be increased to 92.74% in pulping.
