Shelf-life of 'Fuji' apples after CA storage at different temperature

CA 저장 사과 'Fuji'의 Shelf-fife

This study was conducted to estimate the shelf-life of 'Fuji' apples (Malus domestica Borkh) after CA storage. Apples stored In 1%O2+3%CO2, 2%O2+3%CO2 and 3%O2+3%CO2 at 2$^{\circ}C$ and 4$^{\circ}C$ for 8 months were stored in air at 10$^{\circ}C$, 80-85% RH for 16days. As a result of objective analysis, apples stored at 2$^{\circ}C$ wert mort effective in retarding the loss of weight flesh firmness, titratable acidity and peel color than those stored at 4$^{\circ}C$, but not the loss of soluble solid. Among storage atmospheres, 1%O2+3%CO2 at 2$^{\circ}C$ was more effective in retarding the loss of flesh firmness and green color than other atmospheres. Shelf-life of apples kept at 2$^{\circ}C$ estimated above 16 days. The contents of acetaldehyde and ethanol were not observed tn make large difference between storage conditions, but ethanol content of apples stored in 3%O2+3%CO2 at 4$^{\circ}C$ was Increased slightly for 16 days. According to sensory evaluations, apples stored at 2$^{\circ}C$ were significantly harder, juicier and more acid than chose stored at 4$^{\circ}C$. Particularly, high scores of apples stored in 1% and 2%O2+3%CO2 at 2$^{\circ}C$ Persisted for 16 days. Juiciness, hardness acidity and sweetness were related to the flesh firmness and titratable acidity. Overall acceptability was closely related to juiciness and hardness.
