摘　　要：腰果仁的食用品质与其含油量有着密切关系,因此有必要快速、准确的对腰果仁中含油量进行检测和分析.本研究应用一种快速、准确、无损的低场核磁共振技术来测定腰果仁中含油量,同时采用核磁共振成像技术对腰果仁不同部位的油分布进行了检测.研究结果表明：与索氏提取法相比,应用低场核磁共振技术测定腰果仁中油含量方便迅速,结果稳定准确,无污染.磁共振成像图谱表明不同腰果仁含油量不同,腰果仁不同部位含油量不同.The edible quality of cashew kernels had close relationship with its oil content, it was necessary to de-tection the oil content by a rapid and accurate method. This paper applied the low field nuclear magnetic resonance （NMR） technology for determination of oil content and the different parts of distribution of oil in cashew kernel, and it was a more rapid, accurate and nondestructive method . The results showed that the NMR was more rapid, stable and accurate than the Soxlt extraction, much more this method was no pollutions. Magnetic resonance imag-ing results showed that the cashew kernel oil content was not the same as each other and different areas of cashew kernel.
