苹果双向变动气调贮藏初步研究
PRELIMINARY STUDY ON TWO-DIMENSIONAL DYNAMIC CON-TROLLED ATMOSPHERE STORAGE OF APPLE FRUIT
【摘要】 将苹果贮藏在不同温度和不同气体成分组合条件下,定期测定果实的品质和生理生化变化。结果表明,贮藏期间(150-180天)同时变动温度和气体成分,温度从10-15℃降至0℃,CO2从12-15%降至6-8%,O2为3%,获得很好的保鲜效果。这种处理中果实硬度保持在12磅/厘米2以上,显著抑制了果实内乙烯生成和果胶水解。这类贮藏技术建议称为“双向变动气调贮藏”。
【Abstract】 Apple fruit stored in different combinations of temperature and composition of gas mixture was studied. Treatments Ⅰ,Ⅱ, Ⅲ were all stored in low temperature (0℃)during the whole storage period (150-180days)and their gas conditions were: I, in air, O2 21%, CO20%; Ⅱ, O2 3% and CO2 3% or 2%; Ⅲ, O2 3%, CO2 12-15% in the first 30 days, decreased to 6-8% in the next 60 days and remained 6-8% in the rest 90 days. Treatment IV, V, VI were all stored in higher and varied temperatures as follows: 10-15℃ in the first 30 days, decreased to 0℃ in the next 60 days and remained 0℃ in the rest 90 days. Their gas conditions were: IV, the same as treatment I; V. the same as treatment Ⅱ; Ⅵ, the same as treatment Ⅲ. The qualities, physiological and biochemical changes were determined regularly. It was found that treatment Ⅵ with varied temperatures and gas compositions was very good to keep freshness, nearly the same as treatment Ⅱ, the CA storage. The flesh firmness of fruit of treatment Ⅵ was maintained more than 12 Ib/cm2, the ethylene biosynthesis and hydrolysis of protopectin were also inhibited markedly. This kind of storage technique is suggested to be named as "Two-dimensional Dynamic Controlled Atmosphere Storage".
