NSCC涂膜对黄花梨软化和细胞壁代谢的影响
Effect of NSCC coating on ripening and cell wall metabolism in Huanghua pear fruit (Pyrus pyrifolia)
摘要
Abstract
In order to explore the effectiveness of nano-SiOx/chitosan complex (NSCC) on postharvest Huanghua pear fruit (Pyrus pyrifolia Nakai), fruits were stored at 20 ℃ after coating with 1％ NSCC. The effect of NSCC coating on the ripening and cell wall metabolism in fruit was investigated. Results showed that NSCC coating not only significantly delayed the onset of climacteric ethylene production and respiration in fruit, and also significantly decreased the activities of pectinesterase (PE), polygalacturonase (PG) and cellulase during storage. NSCC coating also delayed the depolymerization of propectin, cellulose and inhibited the increase of water soluble pectin (WSP), maintained fruit firmness. Application of NSCC can extend 10 days of the storage life of Huanghua pear fruit.关键词
