Overview | The total alkali of capsicum is capsaicin (Capsaicin,60-70%), dihydrocapsaicin (Dihydrocapsaicin,20-30%) and more than ten analogs, but capsaicin is generally used in medical research. Because the structure and physical and chemical properties of capsaicin analogs are very close, it is difficult to separate monomer compounds. Dihydrocapsaicin content has a great influence on the overall spicy quality and taste of chili, and is one of the important indicators to evaluate the quality of chili. Using traditional chemical analysis methods, such as high performance liquid chromatography and ultraviolet spectrophotometry to determine the content of dihydrocapsaicin, is a destructive analysis, and the experimental drugs used are expensive, the experimental operation is complex, time-consuming and laborious. Near-infrared spectroscopy has the advantages of fast analysis speed, no damage to samples, simple operation, good stability, and high efficiency. It has been widely used in the quality analysis of fruit and vegetable products. |
