Abstract：The study took water chestnuts from Lipu,Guangxi as the research object,with weight loss,hardness,relative conductivity,MDA,SSC,total phenols,flavonoids and quinone contents serving as evaluation indicators.The effects of different irradiation doses of 60Co-γ-rays(0,2,4,6,8 kGy)on the preservation efficacy of fresh water chestnuts were investigated.The results showed that during the storage period of 40 d,the 2 kGy 60Co-γ-ray irradiation treatment group had a weight loss rate of 0.18%,hardness of 3 810 g,relative conductivity of 17.2%,and MDA content of 0.0020-0.002 6 μmol/g FW.It could reduce SSC losses,lower the content of total phenolic,flavonoid,and quinone,inhibit bacterial growth,and effectively delay the decline in water chestnut quality.Therefore,the 2 kGy 60Co-γ-ray irradiation treatment was identified as the optimal dose for postharvest preservation of fresh water chestnuts in the Guangxi,which might provide a theoretical basis for irradiation preservation of postharvest water chestnuts.
