香菇气调保鲜包装工艺研究

以香菇为试验材料,研究1%壳聚糖涂膜结合不同气调包装工艺低温贮藏香菇的保鲜效果。分析了不同保鲜工艺对其感官品质、失重率、Vc含量变化、细胞膜透性等生理生化指标的影响。结果表明,采用1%壳聚糖涂膜结合314μm OPP/PE微孔膜气调包装的方法,可延长货架期到19d,并能较好的保持香菇的感官品质和营养价值。

Research on the Modified Atmosphere Packaging Technology of Lentinus edoes

The Lentinus edoes was coated with 1% chitosan solution prior to different modified atmos- phere packaging(MAP),and then stored at a low temperature.The effects of different packaging technolo- gies on organoleptic test,loss of weight,content of VC and permeability of Lentinus edoes were discussed. The results showed that preservation effect could be achieved when Lentinus edoes was coated by 1% chi- tosan solution along with 314μm OPP/PE microporous membranes MAP.The treatment could extent the shelf life of Lentinus edoes to 19 days,and the nutrition as well as the desirable quality could be well kept.
