Abstract:
... The postharvest decay of durian (Durio zibethinus Murr.) increases rapidly when the storage time is extended, which seriously limits the commercial value. In this research, the effects of appropriate periodical SO₂ fumigation and different CO₂‐enriched atmospheres (3% O₂ + 10%–13%, 14%–17%, or 18%–21% CO₂) on the storage quality of durian stored at 14°C were investigated. Results showed that SO₂ f ...
