Embodiment 1
[0032] The present embodiment discloses the determination of the oxygen free radical absorbing capacity value of different spices, specifically:
[0033] Oxygen radical absorption capacity method (ORAC) was used, Fluorescein and FL were used as fluorescent probes, and the reaction system was composed of FL, AAPH, potassium phosphate buffer solution and antioxidants. After standing for a period of time, UV, fluorescence and LC / The MS method simultaneously detects and analyzes the reaction mixture and records the fluorescence value. The difference between the area under the fluorescence decay curve under the action of antioxidants and the area under the fluorescence natural decay curve is used as an index to measure the antioxidant capacity of antioxidants, and the results are expressed using the antioxidant substance Trolox as a standard. This method was used to evaluate the total antioxidant capacity of 21 common spices.
[0034] The test samples mainly include: chili powder...
