摘  要:
研究了不同辐能流短波紫外线照射处理对采后香菇在4℃贮藏期间主要生理及品质指标的影响。结果表明:经2.0 kJ/m2或4.0 kJ/m2的短波紫外线处理后,可以显著抑制香菇硬度和丙二醛(MDA)含量的上升,延缓还原性糖与维生素C的下降并使维生素C含量维持在较高水平,同时促进了类黄酮的次生代谢合成,从而较好地保持香菇的感官品质和营养价值,延长香菇的贮藏保鲜期。这些结果表明,短波紫外线处理对采后香菇的贮藏保鲜具有潜在的应用前景。

摘  要:
The effects of different dose UV-C treatments on main physiological and quality parameters of shiitake mushrooms during storage were investigated.The experimental results indicated that 2.0 kJ/m2 and 4.0 kJ/m2 UV-C treatment significantly inhibits the increase in firmness and malonaldehyde(MDA) contents,delays the decrease in reducing sugar and vitamin C contents,and promotes synthesis and accumulation of flavonoid,therefore maintaining better quality,nutrition and extending the shelf life of shiitake mushrooms compared with the control treatment.The results suggested that UV-C treatment has the potential to apply on extending the shelf life of shiitake mushrooms.
