Hemp oil is widely used in the food industry, and also in many other industries. It is characterized by a high content of unsaturated fatty acids with the optimal ratio of ω-6 to ω-3 fatty acids (3:1). Such composition means that this oil is often used in the food, pharmaceutical and cosmetic industries. Due to the popularity of hemp oil and its high content of unsaturated fatty acids, methods for the quick oil quality analysis are sought. Six samples of cold-pressed hemp oil were stored under different conditions (2-8 °C and 30 °C) for one month and then their H NMR spectra were recorded. The chemometric methods of PCA and OPLS-DA were used to perform the analysis of the spectra. The combination of those methods made it possible to observe the differences in the oil samples after a month of storage. Based on the H NMR spectra, it was possible to differentiate the time and conditions of the oil storage.
麻籽油广泛应用于食品工业，以及许多其他行业。其特点是含有高比例的不饱和脂肪酸，ω-6 与 ω-3 脂肪酸的比例最佳（3:1）。这种成分意味着这种油通常用于食品、制药和化妆品行业。由于麻籽油的普及和其高含量的不饱和脂肪酸，人们寻求快速分析油质的方法。六份冷榨麻籽油在不同条件下（2-8°C 和 30°C）储存一个月，然后记录它们的 H NMR 光谱。使用 PCA 和 OPLS-DA 的化学计量学方法对光谱进行分析。这些方法的结合使得在储存一个月后观察油样的差异成为可能。基于 H NMR 光谱，可以区分油的储存时间和条件。
