摘  要：
对不同品种核桃坚果壳结构(缝合线紧密度、密度、厚度、机械强度、细胞直径)与坚果种仁商品品质(漂洗污染率、虫果率、裂果率、出仁率、种仁颜色、油脂丙二醛含量)进行研究,并分析二者之间的关系。结果表明:壳结构指标之间存在显著的相关性,它们与种仁商品品质间存在显著的相关性,即缝合线越紧密、壳越厚,漂洗污染率、贮藏虫果率、裂果率越低,种仁颜色越浅,核桃油脂的抗氧化能力越强。建议将壳结构作为坚果品质的评价因素,并对缝合线紧密度和壳厚度予以充分的重视。

摘  要：
The shell structure indexes (seal grade, thickness, density, mechanical strength and cell diameter of shell) and kernel qualities (rate of wormed nut, rate of dissilient nut, kernel ratio, kernel colour, MDA content) of different cultivars in walnut (Juglans regia) were studied. Correlation between structure indexes and kernel qualities was analysis showed that there were significant correlations among the structure indexes, which were also significantly correlated with the kernel qualities. The tighter seal grade was and the thicker the shell was the lower the strain rate, rate of dissilient nut, rate of warmed nut and MDA content of oils in stored walnut kernel were and the stronger the anti-oxidation capacity of walnut was. The results suggested that shell structures should be take into consideration as a factor to evaluate qualities of walnut. The indexes of shell structure, such as seal grade and thickness should receive sufficient attention.
