In this experiment， fresh lotus were selected as the test material， control (CK) was treated with water. Then， the effect of different concentrations(0.2， 0.4， 0.6 mmol/L) of SA treatments on the storage quality and antioxidant enzyme activity of fresh lotus， were investigated during storage at(20±1) ℃. The results showed that compared with the control， SA treatments significantly maintained the sensory quality， inhibited the respiration rate， and delayed the nutrients decline of the lotus seeds. Among of them， 0.4 mmol/L SA treatment were the best， which could effectively delay the increase of lotus seeds browning， soluble solids and malondialdehyde， and inhibit the decreases of reducing sugar， soluble sugar， starch and total phenol content in lotus seeds. Moreover， 0.4 mmol/L SA treatment also could maintain higher superoxide dismutase， catalase， and peroxidase activities of lotus seeds， as well as significantly inhibit polyphenol oxidase activity， thereby delaying the senescence of fresh lotus during storage， and maintaining better quality.
