| Summary: | In order to investgate the effects of H2S on the quality of cold-storage passion fruit, fresh harvested fruits were treated with different concentrations of H2S(0 mmol/L, 1 mmol/L, 2 mmol/L, 3 mmol/L), packaged with BOPP plastic wrap and placed into 5±1°C for 35 days. Samples were randomly selected and at 7-days interval during cold storage, compared the preservation effect of different concentrations of H2S. The results indicated that the fruits with 2 mmol/LH2S treatment have better chroma and lower weight loss rate, and soluble solid content, titratable acidity, vitamin C, sugar were preserved at higher level than that of control fruits during storage time. These results showed that 2 mmol/LH2S treatment could maintain the quality of passion fruit during cold storage.
