The participation of the primary radicals in the bleaching of aqueous solutions of the carotenoid crocin by ionizing radiation was investigated, employing both X-radiolysis and pulse radiolysis. The pulse-radiolytic data demonstrated a very rapid diffusion-controlled attack by both hydroxyl radicals (.OH) and hydrated electrons (eaq-), while superoxide anions (O2-) did not react at all. The site of the initial reaction of these radicals was not limited to the polyene chromophore. Slower secondary reactions involving crocin alkyl or peroxy radicals contribute mainly to the overall bleaching, in particular during steady-state irradiation.
采用X射线辐解和脉冲辐解技术，研究了初级自由基在电离辐射对类胡萝卜素藏红花素水溶液的漂白过程中的参与情况。脉冲辐解数据表明，羟基自由基（·OH）和水合电子（eaq-）均发生了非常快速的扩散控制反应，而超氧阴离子（O2-）根本不发生反应。这些自由基的初始反应位点并不局限于多烯发色团。涉及藏红花素烷基或过氧自由基的较慢二级反应主要对整体漂白起作用，特别是在稳态辐照期间。
