摘要: 研究了热烫温度、热烫时间、热烫固液比以及热烫液加酸量对香蕉热处理过程中PPO酶活以及香蕉浆褐变的影响。结果表明,香蕉热处理的优化条件为:热烫温度为100℃、热烫时间为6min、热烫固液比为1∶5(w∶v)和柠檬酸浓度为0.6%。在此条件下进行验证实验,测得香蕉浆中的残留PPO酶活为16U,香蕉浆液的褐变度仅0.072,对控制香蕉在加工过程中的褐变有明显效果。Abstract: The effect of different blanching temperature, blanching time, solid-to-liquid ratio and blanching pH on the polyphenoloxidase and browning degree of banana serous fluid was studied. To get the best condition of banana blanching, orthogonal experiment after single factors analysis was used. The result showed that the residual activity of polyphenoloxidase and the browning degree of banana serous fluid would be on a low level when the blanching temperature was 100℃, the blanching time was 6min, the solid-to-liquid ratio was 1∶5 and the blanching pH were regulated by citric acid of 0.6 percent concentration. Under such conditions, the polyphenoloxidase was 16U and the browning degree of banana serous fluid was only 0.072, which had obvious effect on browning control in banana processing.
