| Abstract: |
| Aiming to contribute to the industrial production, storage and quality control of cold-pressed fresh green Huajiao oil, the change of pigment in cold-pressed fresh green Huajiao oil was analyzed by ultra-high performance liquid chromatography-diode array detector-high resolution mass spectrometry (UPLC-DAD-HRMS), and the effects of light, oxygen, temperature on the pigment content and color(L*, a*, b*) of fresh green Huajiao oil in storage were determined. The results showed that 32 chlorophylls and 10 carotenoids were identified from the cold-pressed fresh green Huajiao oil. The main chlorophylls were chlorophyll a, C132-hydroxy chlorophyll a, chlorophyll b and pheophytin a; the main carotenoids were lutein and β-carotene. The total chlorophyll content was 9.44 mg/kg, and the total carotenoid content was 4.95 mg/kg. During storage, the main factor affecting the degradation of pigment in fresh green Huajiao oil was light, followed by temperature, and oxygen had little effect. In addition, the color index a* can be used as an index for pigment content and color control. |
