Citral, a promising natural preservative for postharvest quality extension in kiwifruit Citral is an aliphatic aldehyde extracted from citrus essential oil. Scientists at Jiangxi Agricultural University (China) have examined how citral treatment affects the weight loss, firmness, respiration, and ripening index, as well as the antioxidant capacity of kiwifruit ( Actinidia chinensis cv. Jinkui) under cold storage. For the study, kiwifruit were dipped in 0.6 µLm/L citral (prepared in 0.1% Tween 80 solution) for 15 min, then both citral-treated and control kiwifruits were air-dried (at 20 ± 1°C and 90 ± 5% relative humidity), packed in low-density polyethylene bags (39 × 30 cm, 0.03 mm thickness), and then stored at 0-1°C and 90 ± 5% RH for 90 days, during which flesh firmness, quality parameters, membrane permeability, and antioxidant enzyme activities were determined. ....
