| 摘 要： | 以贮藏后期的库尔勒香梨为研究对象，在一定的贮藏期内，定期对香梨中多酚氧化酶活性、酚类物质含量、过氧化物酶活性、丙二醛含量作测定。结果表明，香梨在贮藏期间先进行酚类物质合成，后发生降解，多酚氧化酶活性呈先升后降的趋势，丙二醛含量总体上升。

| Abstract: | The enzymatic browning during storage in Pyrus bretschneideri Rehd was studied by determining PPO and POD activity, content of Phenolic sustance and MDA. Results showed that Phenol compounds were synthesized at first, and then decomposed during storage. The activity of polyphenolic oxidase increased firstly, and then decreased while content of MDA increased. |
