【摘要】 研究了甜樱桃品种“那翁” (PrunusaviumL .cv .Napoleon)在 1℃的高O2 浓度气调 (CA_I:70 %O2 +0 %CO2 )、高CO2 浓度气调 (CA_II:5 %O2 +10 %CO2 )、自发气调 (modifiedatmospherepackage ,MAP)和普通冷藏条件下果实生理、品质、耐藏性的变化。结果表明 :与其他处理相比 ,高O2 浓度的气调可以抑制果实腐烂、减少果肉中乙醇含量 ,但果实的丙二醛 (MDA)含量迅速上升、褐变严重。高CO2 浓度的气调能有效抑制MDA含量上升的速率和多酚氧化酶 (PPO)活性 ,保持果实硬度和维生素C含量 ,减少果实腐烂和褐变 ,延长贮藏寿命。不同处理对果实可溶性固形物含量的影响不大。“那翁”甜樱桃在 5 %O2 +10 %CO2 气调中贮藏 80d能保持果实固有的风味品质。在MAP下 ,70 %O2 +0 %CO2 和普通冷藏中的适宜贮藏期分别为 4 0d、2 0d和 30d。更多还原

【Abstract】 Sweet cherries ( Prunus avium L. cv. Napoleon) were stored in controlled atmospheres (CA) of high O 2(70% O 2+0% CO 2) or high CO 2(5% O 2+10% CO 2), in modified atmosphere package (MAP, (13%-18%) O 2+(2%-4%) CO 2) and in air (control) at 1 ℃ to investigate the effects of different O 2 and CO 2 concentrations on physiological properties, quality and storability of the fruits during storage. The results indicated that compared with other treatments, CA with high O 2 concentration decreased fruit decay and ethanol content, but increased the accumulation of malondialdehyde (MDA) and stimulated browning. CA with high CO 2 concentration inhibited polyphenol oxidase (PPO) activity, reduced MDA content, maintained vitamin C content and firmness, decreased fruit decay and browning. Soluble solids contents (SSC) were not significantly affected by different atmosphere treatments. "Napoleon" fruits stored in 5% O 2+10% CO 2 for as long as 80 d were of good quality, but only 40, 20 and 30 d stored in MAP, 70% O 2+ 0% CO 2 and air, respectively.更多还原
