Jaboticaba (Myriciaria jaboticaba (Vell) Berg.) is a highly perishable Brazilian berry with a shelf life of only 2 days under ambient conditions. Low temperatures and controlled atmosphere (CA) have been used to extend the shelf life of perishable fruit. Thus the aim of this study was to determine the effect of CA with varying concentrations of oxygen (1, 5, 10, 15 and 21 kPa) during cold storage (12.5 °C) of 'Sabará' jaboticaba fruit.
Atmospheres with lower oxygen concentrations (1 and 5 kPa O(2) ) significantly reduced jaboticaba respiration rate. Fruit stored under these conditions had higher L values, and titratable acidity (TA), and lower ratios of soluble solids content (SSC)/TA. However, at the lowest concentration of oxygen (1 kPa O(2) ), firmness decreased markedly compared to fruits stored at higher O(2) levels (P < 0.05). After only 2 days of storage at ambient temperature jaboticaba received a score of 1.6 (dislike strongly - 1) compared to fruit stored under CA, which scored 7.4 (like moderately - 7). After 9 days of storage, fruit from all treatments remained above the limit of acceptability (score 5) and were rated as 6.2. With respect to appearance, statistical differences between treatments were not observed. The total anthocyanin content was not affected by oxygen concentration but decreased 40.4% during CA storage.
'Sabará' jaboticaba fruit can be satisfactorily stored under atmospheres containing 5-21 kPa O(2) at 12.5 °C for up to 6 days.
嘉宝果（Myriciaria jaboticaba (Vell) Berg.）是一种极易腐烂的巴西浆果，在常温下的货架期仅为 2 天。低温和控制气氛（CA）已被用于延长易腐水果的货架期。因此，本研究旨在确定不同氧气浓度（1、5、10、15 和 21 kPa）的 CA 在 12.5°C 冷藏期间对“Sabará”嘉宝果的影响。
氧气浓度较低（1 和 5 kPa O2）的气氛显著降低了嘉宝果的呼吸速率。在这些条件下储存的果实具有较高的 L 值和可滴定酸度（TA），以及较低的可溶性固形物含量（SSC）/TA 比值。然而，在最低氧气浓度（1 kPa O2）下，与在较高 O2 水平下储存的果实相比，硬度明显下降（P < 0.05）。在常温下储存仅 2 天后，嘉宝果的评分为 1.6（非常不喜欢-1），而在 CA 下储存的果实评分为 7.4（中等喜欢-7）。经过 9 天的储存，所有处理的果实仍保持在可接受的范围（评分为 5），并被评为 6.2。关于外观，处理之间没有观察到统计学差异。氧气浓度对总花青素含量没有影响，但在 CA 储存期间下降了 40.4%。
“Sabará”嘉宝果果实可在 12.5°C 下，在 5-21 kPa O2 浓度的气氛中储存长达 6 天。
