中文摘要: 将丙酸杆菌代谢物喷洒到橘子表面,测定贮藏过程中橘子失重率、硬度、菌落总数、大肠菌群数、感官 5 个品 质指标。结果表明,橘子经喷洒丙酸杆菌代谢物后,与相同环境下的常规贮藏相比,失重率明显得以改善;硬度变化幅 度较小;菌落总数和大肠菌群数低于常规贮藏组;外观上,橘子表面颜色基本不变,水分较充足,而常规贮藏的橘子表 面干瘪褐变严重。这说明,丙酸杆菌代谢物对橘子的防腐保鲜起到一定作用。
Abstract:Metabolites of Propionibacterium freudenreichii were sprayed to the surface of orange. Then, weight loss, hardness, total number of colonies, MPN of coliform group and the sensory indicators were determined during storage. The results showed: the orange weight loss improved obviously, small variations in hardness, total number of colonies and MPN of coliform group was lower than the conventional storage group. The orange surface colors basically unchanged, moisture was adequate, when the conventional storage of the surface of the orange dry browning was serious. It indicated that metabolites of Propionibacterium freudenreichii had played a certain role in the preservation of orange.
