Abstract
The effects of UV-C treatment on physicochemical quality, bioactive compounds and antioxidant activity of okra (Abelmoschus esculentus L.) during storage were investigated. Okra pods were exposed to UV-C irradiation dose at 1.5, 3.0 or 6.0 kJ·m−2 before storage at 10 ± 2°C for 12 days. The results showed that UV-C treatment had a significant effect on okra bioactive compounds, such as ascorbic acid, total phenolic, flavonoid contents and antioxidant activity. The highest values of these compounds were observed in okra treated with 6.0 kJ·m−2 UV-C irradiation. A statistical analysis of the data demonstrated that mucilage had a favorable association with antioxidant capabilities and bioactive substances in response to UV-C treatment. Moreover, UV-C treatment also effectively maintained the quality of okra during storage, as evidenced by lower weight loss and higher firmness without incidence of decay. Therefore, postharvest UV-C treatment can be a potential approach to enhance bioactive compounds and maintain the quality of okra during storage.
期刊介绍:
The Horticulture Journal (Hort. J.), which has been renamed from the Journal of the Japanese Society for Horticultural Science (JJSHS) since 2015, has been published with the primary objective of enhancing access to research information offered by the Japanese Society for Horticultural Science, which was founded for the purpose of advancing research and technology related to the production, distribution, and processing of horticultural crops. Since the first issue of JJSHS in 1925, Hort. J./JJSHS has been central to the publication of study results from researchers of an extensive range of horticultural crops, including fruit trees, vegetables, and ornamental plants. The journal is highly regarded overseas as well, and is ranked equally with journals of European and American horticultural societies.
