| 摘 要： | 以新鲜怀山药为试验材料,对其进行无硫护色及热风干燥研究。通过研究多酚氧化酶活性的最适pH值、最适温度及不同护色方案对怀山药的护色效果,得到怀山药多酚氧化酶的特性及抑制剂(NaCl、柠檬酸、VC)对其活力的抑制作用,同时对怀山药热风干燥的规律进行了研究。正交试验结果表明,怀山药最佳无硫护色配比为:NaCl、柠檬酸、VC的质量分数分别为2.2%,1.0%,0.025%,浸泡时间为2h。

| Abstract: | Non-sulfur anti-browning and hot-air drying were investigated by using Chinese yam as material. According to theresults of the optimum pH and temperature for the poly-phenoloxidase activity and the test schema of the anti-browning,thecharacteristic of the poly-phenoloxidase and its activity which could be restrained by three inhibitors (NaCl,citric acid andVC) were obtained. The results of the orthogonal experiment showed that the optimal non-sulfur anti-browning compositions ofthe yam was NaCl 2.2%,citric ... |
