Controlled Atmosphere (CA) 환경설정 해제 후 저온저장이 ‘후지’ 과실의 품질에 미치는 영향

초록

This study aimed to evaluate the fruit quality characteristics and incidence of flesh browning in response to air storage at 0 +/- 1 degrees C after controlled atmosphere storage (CA condition: O-2 2.5 +/- 0.5%, CO2 1.5 +/- 0.5%) at 0 +/- 1 degrees C in 'Fuji' apples (Malus domestica Borkh.). The storage system was performed as followed: air storage for one month, CA storage 4 months + air storage 3 months (CA 4M + Air 3M), CA storage 5 months + air storage 2 months (CA 5M + Air 2M) and CA storage 6 months + air storage 1months (CA 6M + Air 1M), while the control fruits were stored at CA storage for 8 months right after harvest. The incidence of flesh browning ranged from 17.1% to 30.2% during CA storage but not detected under the treatments of CA 4M + Air 3M and CA 5M + Air 2M. The respiration rate was not affected by storage treatments for 6M while the respiration rate was lower in the treatments of CA 4M + Air 3M and CA 5M + Air 2M than the other storage treatments after 7 months. Ethylene production and internal ethylene concentration were lowest in rapid CA storage and increased with a decreasing CA storage duration. Therefore, the results indicate that CA 5M + Air 2M storage treatment should be recommended to maintain the fruit quality and reduce the risk development of flesh browning rather than typical CA storage in 'Fuji' apples.
