【摘要】 中国板栗以其优良品质驰名中外,尤以燕山一带生产的板栗,它是主要的外销果品之一。长期以来,我国板栗的贮藏和运输,处理粗放,设备简陋,且在常温下进行,因而造成失重、发芽、变质与腐烂等问题,急待改进提高。通过1980年至1985年研究,证明中国板栗的优良品质和它的贮藏性状,采用了低温和高温的流通链方式。主要技术包括:采收成熟的栗子、湿沙预贮、良好包装、预冷、快速运输和冷藏。采用冷藏可以延长板栗的贮藏寿命并保持优良的品质,将板栗装在聚乙烯薄膜袋内,置于温度-2～0℃,相对湿度90％以上,在CO₂低于5％条件下,可贮藏7～10个月。试验证明低温是保证收获后板栗质量的重要条件,冷链流通是今后外销板栗获得成功必需采取的措施。更多还原

【Abstract】 Chinese famous chestnuts espcially produced in Yan-mountain area possess a very nice quality and well known to the Japanese.Is is one the important nuts for export. Chestnuts were transported and stored at ordinary amibient temperature, with poor equipment and rough practice, so weight loose, quality deterioa- tion, rot and seed germination were main problems, since long time. This study carried on experiment from 1980 to 1985, showed a nice eating quality of Chinese chestnuts by chemical analysis.The storage chara- cteristics of chestnuts were also abserved. The transporting chain was carried under low temperature and high humidity. The comprehensive tech- nique includes picking ripe nuts, prestoring in wet-sand, packing in PVC film bags, precooling in cold store and quick transporting. Under temperat- ure of -2-0℃, CO 2<50% and RH above 90%, chestnuts could be stored for 7-10 months with pretty good quality. By using this technique,chestnuts export to Japan had achieved success evidently.更多还原
