摘要: 研究乌梅提取液对鲜切皇冠梨的保鲜作用。鲜切皇冠梨经过乌梅提取液浸泡5min,用保鲜膜和托盘密封包装后,在4℃条件贮藏9d。在贮藏过程中,从菌落总数、质构、VC含量、质量损失率、电导率、可溶性固形物等方面评价保鲜效果。结果表明,乌梅提取液能够使鲜切皇冠梨保鲜9d,且皇冠梨的品质和水分保持良好。

Abstract: Fresh-cut Huangguan pear was immersed in ethanol extract (100 mg/mL) of Fructus Mume for 5 min, air-dried, packaged with clear plastic wrap and stored at 4 ℃. During the storage, the total bacterial count, texture, content of vitamin C, weight lose, relative conductivity, phenol oxidase (PPO) activity, soluble solid content of Huangguan pear were determined every three days. Results showed that Fructus Mume extract could prolong the shelf life of fresh-cut Huangguan pear to 9 d, of which the fruit quality and water content remained good.
