Andean blackberries are appreciated for their unique flavor, high nutritional quality, and antioxidant properties. In this study, the effectiveness of low doses (0.4; 0.5; 0.6 and 0.7 µL for 3 min) of gaseous ozone as an elicitor for health-promoting compounds was evaluated during 10 d of storage at 6 ± 1 °C. The physicochemical and sensory quality of the fruit was also determined. Ozone was used in a single application before storage. Initially, regardless of the dose applied, no negative effects of the O treatments were observed in any of the parameters studied. In addition, the firmness, the antioxidant activity and the fructose, vitamin C and polyphenols contents were higher in the O-treated fruit compared to the control. During storage, these differences were maintained except for the 0.7 µL dose. This indicates that low concentrations of gaseous O could promote the synthesis of biocompounds and be effective in maintaining the postharvest quality of blackberries for at least 4 days of refrigerated storage. However, more research is needed to maintain these advantages during longer storage periods.

低剂量气态臭氧作为安第斯黑莓（Rubus glaucus Benth）中促进健康的化合物的诱导剂


安第斯黑莓因其独特的风味、高营养品质和抗氧化特性而受到赞赏。在这项研究中，评估了低剂量（0.4；0.5；0.6 和 0.7 µL，持续 3 分钟）气态臭氧作为促进健康化合物的引发剂的有效性，并在 6 ± 1 °C 储存 10 天期间进行了评估。还测定了水果的理化和感官质量。储存前一次性使用臭氧。最初，无论施加多少剂量，在任何研究参数中都没有观察到 O2 处理的负面影响。此外，与对照相比，O处理的果实的硬度、抗氧化活性以及果糖、维生素C和多酚含量更高。在储存过程中，除了 0.7 µL 剂量外，这些差异均保持不变。这表明低浓度的气态O可以促进生物化合物的合成，并能有效维持黑莓采后至少4天的冷藏品质。然而，需要更多的研究来在较长的储存期内保持这些优势。
