In human nutrition fats are physiologically important food constituents but also the components most liable to oxidative degradation. The oils included in the study were refined (sunflower, extra-sunf...
基于傅里叶红外光谱重组技术的食用油检测改进研究(Improved Application of FTIR Spectral Reconstitution Technique in Edible Oils Analysis)
食用油 傅里叶红外光谱 光谱重组技术
2009/11/3
以食用油、无色矿物精油(OMS)、六羰基铬为试验材料,利用二维相关振动光谱技术对FTIR光谱重组(SR)检测中OMS特征吸收峰取代光谱标记物进行评价研究。结果表明在单一菜籽油体系中,有9个相关吸收峰可用于TVF预测定量分析。考虑不同因素影响,相关吸收峰减至4个。最优相关吸收峰测定OMS体积分数相关性好于标记物特征吸收峰,受混合样品极性变化影响较少。在食用油和OMS混合物中既可用光谱标记物也可用OM...

near-infrared spectroscopy nondestructive analysis fatty acids
2010/11/22
Near-infrared (NIR) transflectance spectroscopy scanning from 1100 nm to 2500 nm was applied for the determination of palmitic acid (C16:0), oleic acid (C18:1) and linoleic acid (C18:2), the major fat...
Quality Evaluation of Edible Oils by Proton Nuclear Magnetic Resonance Measurement
1H-NMR external proton standard
2010/11/22
1H-nuclear magnetic resonance (NMR) method using dioxane as the external proton standard was established to evaluate the quality of edible oils. The number of olefinic protons (OP) in oil was determin...
