'polifenol oxidase'是英语单词,可以翻译为多酚氧化酶。这是一种酶,可以氧化多酚类物质,如水果、蔬菜中的鞣质和酚类化合物,导致其颜色变暗、口感变酸等。这种酶在食品加工、酿造、果蔬保存等领域有重要应用。以下是9个例句:
1. The activity of polifenol oxidase in apple slices decreased during storage. (多酚氧化酶在苹果切片中的活性在存储过程中下降。)
2. The addition of ascorbic acid inhibited the activity of polifenol oxidase. (加入抗坏血酸可以抑制多酚氧化酶的活性。)
3. The polifenol oxidase reaction resulted in the browning of banana slices. (多酚氧化酶反应导致香蕉片变色。)
4. The extraction of polifenol oxidase from mushroom was carried out using ammonium sulfate precipitation. (用硫酸铵沉淀法从蘑菇中提取多酚氧化酶。)
5. The presence of metal ions can activate polifenol oxidase. (金属离子的存在可以激活多酚氧化酶。)
6. The inhibition of polifenol oxidase activity in grape juice by high hydrostatic pressure was studied. (研究了高静压对葡萄汁中多酚氧化酶活性的抑制作用。)
7. Polifenol oxidase is involved in the brown color formation in tea beverage. (多酚氧化酶参与了茶饮料中棕色色素的形成。)
8. The expression of polifenol oxidase gene in tomato fruits was induced by high temperature stress. (高温胁迫诱导了番茄果实中多酚氧化酶基因的表达。)
9. The enzymatic browning of mushroom can be controlled by regulating polifenol oxidase activity. (通过调节多酚氧化酶活性,可以控制蘑菇的酶促变色。)
