保鲜剂在平菇保鲜中的应用研究

Study on preservation of Pleurtus ostreatus by chemical treatment

对柠檬酸、无水亚硫酸钠、氯化钠、比久四种保鲜剂以及不同保鲜方式对平菇的保鲜效果进行比较 ,结果表明 :使用 2 5 0 mg·L-1无水亚硫酸钠溶液处理平菇 ,放置在内置吸水剂的密封保鲜袋中贮藏 ,保鲜效果理想 ,保鲜时间为 8d,外观品质保持良好 ,失重率为 4.8% ,水渍、软化。

An available method for preservation of Pleurtus ostreatus is by liquid of NaSO 3 with 250 mg·L -1 . The Pleurtus ostreatus can retained best exterior quality for 8 days in a sealed plastic bag with absorbent.The speed of weight losing,water logging,softening and brown staining is lower than treatment by NaCl,C 6H 8O 7H 2O and C 6H 12 N 2O 3.
