| 摘 要： | 应用低场核磁共振方法分别测定了米糠毛油和3种食用植物油(花生油、橄榄油和葵花籽油)的弛豫图谱,发现在10 ms左右米糠毛油弛豫图谱中出现了一明显特征峰,而其他3种纯油品均未检出,且随着米糠毛油掺入量的增多,该峰面积的比例也随之增大。结果表明,通过测定该特征峰面积比例可定量测出米糠毛油掺伪量。

| Abstract: | The relaxation maps of three edible vegetable oils(peanut oil,sunflower seed oil and sunflower seed oil) and rice bran crude oil were detected by low-field nuclear magnetic resonance technology(NMR).An obvious characteristic peak has been determined in the relaxation maps of rice bran crude oil at 10ms,which can not be detected in the other three kinds of pure edible oil.And the area proportion increased with the increase of rice bran crude oil content.Therefore,the detecting of the characteristic peak area... |
