Abstract: Fresh harvested Strawberries (Fragaria (ananassa Duch. cv. YongFeng) were subjected to heat treatments. Based onpreliminary experiments, four treatment conditions were applied to strawberries by exposure to hot air (46℃-1h and 48℃-30min) and immersion in hot water (44℃-20min and 46℃-15min). Afterwards, the fruits respiration and quality were moni-tored after 1 day of refrigeration (1±0.5℃) and during 3 days of shelf life (20±1℃) conditions. It was found that fruits withheat treatments had weaker respiration. Hot water immersion was effective in control of Rhizopus stolonifer which is one categoryof mold often causing post-harvest decay of strawberry. Fruits heated at 48℃ for 30min with hot air and 44℃ for 20min withhot water had higher quality values than others.
