This experiment explored the low power microwave treatment effect on mature and aging of strawberry storage. Different microwave power and 120s treatment were used. Then strawberries were stored at 1℃; the indexes of physiological,biochemical and quality were tested regularly. Experimental results show that: Low power microwave treatment had no obvious effect on fruits' temperature rising,had significantly effect of inhibiting respiratory rates and delayed the reducing rate of soluble solids content,sugar,titratable acid and Vc content,kept the firmness of strawberries; lowered cellulase activity and MDA content compared with the control. The 100W /120s microwave treatment had the best effect. When the microwave power was greater than 165W /120 s,it damaged the physiological and quality of strawberry. These showed that low microwave power treatment have certain biological effect and can delay the mature and aging of strawberry.
