摘  要：
壳寡糖(oligochitosan,OCH)是一类由N-乙酰氨基葡萄糖或氨基葡萄糖通过β-1,4-糖苷键连接起来的低聚合度水溶性的氨基葡聚糖,在农业、食品、医药等领域具有广泛用途。本文综述了OCH对果蔬采后病原菌生长的抑制活性,以及OCH相对分子质量和使用浓度对其抑菌活性的影响。进一步综述了OCH对采后病害的控制作用,对果蔬诱导抗病性、活性氧代谢和抗病相关酶活性的影响。OCH是一种对环境友好的、生物源采后病害诱导剂。OCH及其复配处理在果蔬采后病害防治方面将具有重要应用前景。

摘  要：
Oligochitosan(OCH) is a water-soluble low carbohydrate polymer consisting of β-1,4-linked 2-acetamido-Dglucose and β-1,4-linked 2-amino-D-glucose units. OCH has been universally used in the fields of agriculture, food and medicine. Antifungal activity of OCH on the growth of pathogens causing postharvest diseases of fruits and vegetables, and how its application is affected by molecular weight and concentration are reviewed in this paper. Inhibitory effect of OCH on postharvest diseases, and the effect of OCH on the induced infection resistance, the metabolism of reactive oxygen species(ROS) and the activities of defense-related enzymes in fruits and vegetables are further discussed. Therefore, OCH is an environment-friendly biological inducer for the resistance to postharvest diseases. The application of OCH and its combinations with other materials will provide a promising method for the prevention of postharvest diseases of fruits and vegetables.
