    Abstract:
    Saffron, the dried stigmas of Crocus sativus L., is used as a condiment spice. The major bioactive compounds are crocins, picrocrocin and safranal, which are responsible for the sensory profile of saffron (color, flavor and aroma, respectively), and also health-promoting properties. In this paper, the effect on the bioactive compounds of different cooking times in boiling water at 100 °C in samples of Saffron from La Mancha (safranal, picrocrocin, trans-crocin 4, cis-crocin 4 and trans-crocin 3) was investigated. Performance characteristics of High Performance Liquid Chromatography with Variable Wavelength Detector method, parameters of linearity, limits of detection and quantification are reported. High Performance Liquid Chromatography-Photo Diode Array-Mass Spectrometry was used as a confirmatory technique in crocins identification. When the samples are subjected to different cooking times, they present different behaviors, depending on the bioactive compound. In this way, no changes were observed in the concentration of picrocrocin, while heat culinary treatment adversely affects the concentrations of crocins and safranal.
