摘要
为找到一种适合香菇的简便、低成本和安全环保的保鲜方法,研究葡萄籽提取物在香菇贮藏期间对香菇品质的影响。鲜香菇在不同质量浓度(0、1、5、10g/L和20g/L)的葡萄籽提取物(GSE)水溶液中浸泡并风干后,于4℃保存。与对照组相比,经1、5、10g/L葡萄籽提取物处理后的香菇在贮藏期间可以保持良好的感官品质,降低质量损失速率,控制丙二醛的生成,但是高质量浓度(20g/L)的葡萄籽提取物可引起香菇菇盖颜色加深。另外葡萄籽提取物还能有效抑制香菇中细菌的生长,但是对总酚、营养物质的影响不显著。结果表明:一定浓度的葡萄籽提取物能有效地延长香菇的保鲜时间,5g/L的葡萄籽提取物的保鲜效果最理想。
In order to preserve fresh shiitake mushroom conveniently and environmentally, the effect of grape seed extract (GSE) of different concentrations (0, 1, 5, 10, 20 g/L) on freshly harvested shiitake mushrooms stored 4 ℃ were investigated. The results showed that GSE at concentrations of 1, 5 g/L and 10g/L could maintain sensory quality, reduce weight loss and MDA production in shiitake mushroom; but 20 g/L GSE darkened the color of shiitake mushroom. Therefore, GSE possesses antibacterial effect, but no significant effect on total phenolics and nutrient. This study implies that GSE can effectively extend the shelf life of shiitake mushroom with an optima/concentration of 5 g/L.
