摘要
为了延长樱桃的保鲜时间,通过控制气调包装的不同气体比例对山东烟台产的雷尼樱桃进行保鲜,测定保鲜30,60,90,120 d后樱桃的腐烂率、硬度、可滴定酸含量和可溶性固形物含量等指标,确定雷尼樱桃气调包装保鲜的最佳气体比例。结果表明,当气体比例O2浓度为7%,CO2浓度为20%,气调保鲜雷尼樱桃效果最好。在此条件下保鲜的雷尼樱桃,果实腐烂率最低,可滴定酸和可溶性固形物含量变化相对较小,樱桃果肉的硬度变化也相对较小。
Rainier cherries collected in Yantai,Shandong were treated with controlled gases by using modified atmosphere packaging（MAP） technique and stored for 30 days,60 days,90 days,120 days to observe their decay rate,hardness,titratable acid content,soluble solids content and other indicators to determine the best proportion of gases for the modified atmosphere packaging of fresh Rainier cherries.The results show that the modified atmosphere packaging of Rainier cherries had the best storage effect when the O_2 was 7% and the CO_2 was 20% in the modified atmospheric gases.Under this condition the fresh Rainier cherries treated had the lowest fruit decay rate,and relatively lower change in titratable acid and soluble solids content as well asflesh hardness.
