摘要/Abstract

摘要： 香椿（Toona sinensis）的嫩叶和嫩芽营养丰富，风味独特，但香椿属于季节性蔬菜，极易腐烂，严重影响货架期。葡萄柚籽提取物（grapefruit seed extract，GSE）是天然的强抗氧化剂、天然防腐剂。使用0.02 mm厚度的聚乙烯（polyethylene，PE）薄膜包装香椿并利用0.1%、0.3%和0.5%浓度的GSE进行处理，研究不同处理下贮藏期间香椿感官品质与理化指标的影响。结果表明：不同处理均具有一定的保鲜效果。其中，0.5% GSE+PE处理可以显著延缓香椿褐变和腐烂，降低失重率，控制叶绿素含量的升高，抑制呼吸速率和乙烯释放速率。研究结果为香椿的采后保鲜提供了重要的理论依据和实践参考。

Abstract: The young leaves and sprouts of the Toona sinensis are nutritious and special flavour. However, as a seasonal vegetable, Toona sinensis is highly perishable, thus has a short shelf life. Grapefruit seed extract (GSE) is a naturally strong antioxidant and preservative. Toona sineasis was packaged by polyethylene (PE) film with a thickness of 0.02 mm and treated by GSE of a concentration of 0.1%, 0.3% and 0.5%. The sensory quality and physicochemical indexes of the toon during storage under different treatments were studied. The results showed that: different treatments had a certain preservation effects. Among them, 0.5% GSE+PE treatment could significantly delay browning and rot of toona sinensis, reduce weight loss, control the increase of chlorophyll content, and inhibit respiration rate and ethylene release rate. The research results provided an important theoretical basis and practical reference for the fresh-keeping of toona sinensis after harvest.
