abstract:
controlled atmosphere (ca) has not been implemented so far for storage of grapes, partly because the threshold for prevention of decay can overlap the accumulation of off-flavors. 'sable seedless®' was stored under ambient atmosphere or under ca conditions of 5 kpa o2 and 5, 10 and 15 kpa of co2. the level of decay in the experiment was low, in part because the fruit were sanitized with ethanol before storage. off-flavors developed in grapes stored at the high co2 level and the berries were sampled for volatile and non-volatile metabolites. volatile compounds associated with off-flavor were mainly pyruvate degradation products which accumulated in the high co2 atmosphere. analysis of phenylpropanoid metabolites suggested that flavonols and anthocyanins were lower in fruit stored in the high co2 ca conditions. of the stilbenes, trans-resveratrol and piceatannol were higher in the control compared to the high co2 ca conditions. these results point on potential markers for negative effects of ca in table grapes and that extreme ca conditions can modulate the phenylpropanoid pathway.
到目前为止，还没有对葡萄的贮藏实施控制性大气(ca)，部分原因是防止腐烂的门槛可能与异味的积累重叠sable seedless葡萄是在环境空气或5千帕氧气和5千帕、10千帕和15千帕二氧化碳的条件下储存的。实验中腐烂程度较低，部分原因是果实在贮藏前用乙醇消毒。在高二氧化碳水平下贮藏的葡萄和浆果中产生的异味被采集到挥发性和非挥发性代谢物中。与异味有关的挥发性物质主要是丙酮酸降解产物，在高co2气氛中积累。苯丙酸代谢产物分析表明，在高co2-ca条件下贮藏的果实中黄酮醇和花青素含量较低。在二苯乙烯类化合物中，反式白藜芦醇和苦楝醇在对照组中的含量高于高co2-ca条件。这些结果表明，在表生葡萄中钙的潜在负效应标记和钙条件可以调节苯丙酸途径。
