摘要: 采用不同透气性的包装薄膜对生鲜香菇进行包装,通过测定香菇在贮藏过程中的呼吸强度、质量损失率、可溶性固形物、硬度、白度和抗坏血酸等指标,研究不同包装材料对香菇保鲜的影响。结果表明:在温度4℃,相对湿度90%环境条件下,CPP30μm薄膜与LDPE30μm和CPP50μm薄膜相比,能使香菇维持最低的呼吸强度和质量损失率,且最大程度地保持香菇中可溶性固形物含量(P<0.05);3种薄膜对于香菇硬度以及白度的影响不显著(P>0.05);在贮藏前期,薄膜对抗坏血酸(VC)的影响不显著(P>0.05),而在贮藏后期,LDPE30μm处理组的VC含量要高于其他两种处理组。

Abstract: Fresh Lentinus edodes was packaged using packaging films with different gas permeability and the effects of different packaging materials on the qualities of fresh Lentinus edodes were studied by measuring changes in respiration rate, weight loss rate, soluble solid content, hardness, whiteness and ascorbic acid content during storage at 4 ℃ and 90% humidity. Results indicated fresh Lentinus edodes packaged with a 30-micron film reserved the lowest respiration rate and weight loss rate, and the highest soluble solid content compared with other packaging films. The influences of films on hardness and whiteness of Lentinus edodes were not significant (P > 0.05). In the early storage the impacts of films on the ascorbic acid content were not significant (P > 0.05), while in the late storage ascorbic acid content in Lentinus edodes packaged with a 30-micron low density polyethylene film was higher than in Lentinus edodes packaged with other films.

Key words: packaging film, permeability, Lentinus edodes, preservatio
