摘　　要：本研究旨在对油茶籽饼、油茶籽粕和油茶籽仁粉的性状、常规营养成分和主要生物活性成分进行测定和对比分析。研究结果显示:与油茶籽饼和油茶籽粕相比,油茶籽仁粉性状优势突出,为类白色粉末,苦涩味淡,呈多孔蜂窝状微观结构;富含营养和生物活性成分,其粗蛋白质、总糖和油茶皂苷含量较高,分别为11.66%、38.50%和18.85%;粗纤维和单宁含量较低,分别为8.60%和1.25%。以上结果表明,油茶籽仁粉的性状、常规营养成分和主要生物活性成分都优于油茶籽饼和油茶籽粕,具有作为新型和特色饲料资源开发利用的巨大潜力。The purpose of this study was to determine and compare the characteristics,conventional nutrients and main bioactive components of Camellia oleifera seed cake,Camellia oleifera seed meal and Camellia oleifera seed kernel powder.The results showed that,compared with Camellia oleifera seed cake and Camellia oleifera seed meal,Camellia oleifera seed kernel powder had prominent advantages,being white powder with light bitter taste and porous honeycomb microstructure.Camellia oleifera seed kernel powder was rich in nutrition and bioactive components,and its crude protein,total sugar and sasanquasaponin contents were higher,which were 11.66%,38.50%and 18.85%,respectively.The contents of crude fiber and tannin were lower,which were 8.60%and 1.25%,respectively.The above results demonstrated that the characteristics,conventional nutrients and main bioactive components of Camellia oleifera seed kernel powder was superior to Camellia oleifera seed cake and Camellia oleifera seed meal,which had great potential for development and utilization as new and special feed resources.
