【摘要】 目的:为了筛选对巴戟天有明显抑菌作用保鲜剂,对其表面微生物数量进行测定,并对细菌、霉菌的种类进行分离与鉴定。方法:应用细菌和霉菌分类鉴定法。结果:经10 g牛蒡低聚果糖,20 g壳聚糖和0.5 g山梨酸钾的组合保鲜剂处理60 d后,巴戟天表面细菌总数为3.0×104cfu/g,霉菌总数为1.5×104cfu/g,保鲜效果优于其他处理。结论:巴戟天表面常见的优势菌群分别为明串球菌属、气球菌属和青霉属。更多还原

【Abstract】 objective: In order to select antistaling agent which had obvious antibacterial effect on Morinda officinalis,the colony counts of microorganism from the surface of Morinda officinalis and the species of bacteria and mycete were analyzed. Methods: Bacteria and moulds classification identification method were carried out. Results: After using 10 g burdock oligosaccharide,20 g chitosan and0. 5 g potassium sorbate treated for 60 d,the total bacteria on the surface of Morinda officinalis was 3. 0 × 104 cfu / g,mycete total of 1. 5× 104 cfu / g,preservation effect was better than the other treatments. Conclusion: The common advantage microorganisms group of Morinda officinalis on the surface are from Leuconostoc,Aerococcus and Penicillium genera.更多还原
