摘要
通过4次不同的采摘时期综合评定10个种源香椿芽菜的感官品质及营养成分的动态变化趋势,获得香椿芽菜的优质食用价值分析。感官品质评价结果表明:得分最高的贵州黔西南州种源食用价值最高,品质最好。其他各个种源之间达到了显著水平;10个种源香椿芽菜在4次采摘时间下蛋白质、氨基酸变化规律分别呈现升—降与升—降—升的变化规律,而维生素C则无明显变化规律。不同采摘时期的香椿芽菜营养成分的含量与感官品质之间存在一定的相关关系。
The sensory and nutritional dynamics of ten provenances of Toona sinensis were studied to evaluate their quality and edible values.The results showed that there was a significant difference in sensory quality between the 10 Toona sinensis provenances and the provenance Qianxinan Autonomous Prefecture of Guizhou was the best for edible value（92 points）.The proteins content in the sprouts of ten provenances was increased at the early stage of growth and then decreased in the late stage,while the amino acids content in the sprout was showed as ＂increase-decrease-increase＂ with the time.The Vitamin C content in the sprout was not obviously changed with time.There was a certain correlation between the nutrition content and the sensory quality.
