【摘要】 通过多种药剂影响板栗耐贮性试验 ,筛选出了一种多功能复合保鲜剂BFD (百腐敌 ) ,对不同分散剂提高保鲜剂保鲜效果进行了试验 ,确定了其最佳配方及生产工艺流程和最佳使用浓度 ,并进行了多年、多点、多品种保鲜效果试验和毒性测定及营养成份分析。结果表明 :BFD保鲜剂处理栗果可延缓采后衰老 ,兼具杀虫、杀菌多种功能。采用保鲜剂适宜浓度处理栗苞 ,室温条件下贮藏 10 0～ 12 0d ,鲜果率 95%以上 ;坚果经保鲜剂处理后低温库贮藏 12 0～ 180d ,鲜果率 96%以上。贮后紧果色香味匀佳 ,营养成分同刚采下的坚果相近 ,含糖量增加。BFD性能稳定、使用方便 ,投资少 ,价格便宜 ,不污染环境 ,对人畜低毒 (LD50大于 50 0 0mg/kg)且可自行分解 ,适合大面积推广应用。更多还原

【Abstract】 The preserve freshness regulator (BFD) was selected out from several store-resisting experiments of Castanea mollissima by many regulators.Based on the experiments of effects on preserve freshness different regulator,the favored formula,production process and rational concentration were conculated.And the effect of preserve freshness experiments,poisonousness determination,analysis on the composition of nutrition were did in different years,places and varieties.The preserve freshness regulator (BFD) can delay wither,kill insect and disinfect.The cone of Castanea mollissima treated infavored concentration of BFD and in the indoor temperature 100～120days,the rate of fresh fruit up to 95%.The nut treated by BFD and stored in low temperature 120～180 days,the rate of fresh fruit up to 96%.There was no difference between the nut in store by BFD and pick exactly,and the content of sugar as increase.The BFD had stable function,easily use,less investigation,cheap,did’t polluted environment,low poisonousness and self-decompose.It was suitable to popularize in large area.更多还原
