The method on trans fatty acids analysis in food is very important. The effects of methylate sodium, potassium hydroxide, sulfuric acid and boron trifluoride in methanol and their different concentration and dosage on TFA analysis were studied. The chromatographic condition and the influence of time and temperature on the esterifation of TFA using boron trifluoride in methanol were optimized. A method for analyzing TFA were established by GC based on boron trifluoride in methanol and RT-2560(100m×0.25mm×0.2μm) capillary column.

This showed that the main peak position of the transmission light is between 530-540 nm, and the color saturation is about 80%. The dense green color of the uvarovite sample is caused by its higher color saturation. The theoretical analysis of the mechanism of the green coloring of uvarovite indicates that the transition of 3d-orbital electron in the Cr(superscript 3+) is responsible for the green color.
