不同降解方法下β-胡萝卜素降解产物的分析
Analysis of β-carotene Degradation Products with Different Degradation Ways
摘要
Abstract
Carotenoids are the precursors of the tobacco flavor components and play an important role in tobacco quality. In order to expand the source of tobacco flavors and fragrances, the β-carotene was degradated under different conditions and the degradation products were analyzed by GC/MS. The β-carotene was degradated with hydrogen peroxide oxidation, copper sulfate catalyst-hydrogen peroxide oxidation, silver nitrate catalyst-hydrogen peroxide oxidation and potassium permanganate oxidation-hydrogen peroxide oxidation, respectively. It is found that the degradation products identified were important flavor components in tobacco. The content of dihydro actinidiolide and β-ionone were the higher than other flavor components. The relative content of dihydro actinidiolide determined with silver nitrate catalyst-hydrogen peroxide oxidation and potassium permanganate oxidation-hydrogen peroxide oxidation were higher than that with the others. The relative content of β-ionone determined with hydrogen peroxide oxidation and potassium permanganate oxidation-hydrogen peroxide oxidation were more than the others. It is conlucded that the β-carotene can be degradated into dihydro actinidiolide, β-ionone, isophorone, 3,5,5 trimethylcyclohexene 1,4 dione and other flavor components, and the degradation products and relative content are different under different degradation ..conditions.关键词
