摘要

本研究旨在确定收获前草酸(OA)处理对韭菜储存期间的生化含量和质量的影响。为此,在收获前 6 周、4 周和 2 周用含 0(对照组)、1、2 和 3 mM OA 和 0.1% Tween-20 的溶液处理韭菜。包装好的韭菜在 0 °C 和 90 ± 5%相对湿度(RH)条件下储存 50 天。冷藏后,韭菜在 20 °C 和 60 ± 5% 相对湿度条件下保存 3 天,以确定货架期。OA 处理对韭菜的重量损失、外观和生物活性化合物都有显著影响。贮藏结束时,对照组抗坏血酸(AsA)含量的损失为 55.53%,3 mM OA 处理组为 22.89%。同样,对照组的总酚(TP)含量和抗氧化活性(AOA)分别下降了 37.34% 和 45.70%,而在 3 mM OA 处理中,这两个值分别为 26.94% 和 32.65%。3 mM OA 处理是本研究中的高剂量,它能更好地保持韭菜中的 AsA、TP 和 AOA 含量。冷藏结束时,对照组外观评分的变化率为 46.33%,而 OA 处理组的变化率为 31.44%(2 mM OA)和 42.55%(1 mM OA)。因此,经 OA 处理和微处理的韭菜可在 0 °C 和 90 ± 5% 相对湿度条件下成功贮藏 50 天。此外,在这项研究中,OA 的功效呈剂量依赖性增长。

Oxalic acid treatment delays quality loss and biochemical changes of minimally processed leeks during storage

In the present study, it was aimed to determine the effects of preharvest oxalic acid (OA) treatments on the biochemical content and quality of minimally processed leeks during storage. For this purpose, leeks were treated with solutions containing 0 (control), 1, 2 and 3 mM OA and 0.1% Tween-20 with a pump 6, 4 and 2 weeks before harvest. The packaged leeks were stored at 0 °C and 90 ± 5% relative humidity (RH) for 50 days. After the cold storage, the leeks were kept at 20 °C and 60 ± 5% RH for 3 days to determine the shelf-life. The effects of OA treatments on the weight loss, external appearance and bioactive compounds were remarkable. At the end of storage, the losses of ascorbic acid (AsA) content were determined as 55.53% in the control group and 22.89% in the 3 mM OA treatment. Similarly, the decrease in total phenolic (TP) content and antioxidant activity (AOA) in the control group was 37.34% and 45.70%, respectively, while these values were determined as 26.94% and 32.65% in the 3 mM OA treatment, respectively. With 3 mM OA treatment, the high dose in this study, the AsA, TP, and AOA contents of leeks were better preserved. The change in the external appearance scores at the end of cold storage was determined as 46.33% in the control group whereas it was determined between 31.44% (2 mM OA) and 42.55% (1 mM OA) in OA treatments. As a result, OA-treated and minimally processed leeks were successfully stored for 50 days at 0 °C and 90 ± 5% RH. Moreover, the efficacy of OA increased in a dose-dependent manner in the study.
