鲜湿豆丝保鲜研究

Research on preservation of the fresh bean silk

研究了紫外杀菌时间、水的添加量、复合脱氧剂的配比和复合脱氧剂的用量对鲜湿豆丝的保鲜效果。通过单因素实验和正交试验,得到豆丝保鲜的最佳方案为:脱氧剂Ⅰ∶脱氧剂Ⅱ为4∶1,不添加水,紫外杀菌10 min。按此方案保鲜的鲜湿豆丝,37℃恒温保藏3 d,其菌落总数不超过105cfu/g,霉菌总数不超过150个/g。

The ultraviolet sterilization time,the addition of water,the proportioning of compound deoxidizers and the weight of compound deoxidizers whose effect on the preservation of the fresh dousi during preservation are researched.After single factor and orthogonal test,the best way of preservation we get is：deoxidizer Ⅰ： deoxidizer Ⅱ is 4∶1,without water,the ultraviolet sterilization time is 10 minutes.The fresh dousi whose total number of colonies is less than 105 cfu/g and mold is less than 150/g while preserved in 37 ℃ for 3 days in this method.
