Abstract
Climate change has led to rediscovery of minor drought tolerant grains such as millet. Among its bioactive molecules, steryl ferulates have been poorly explored. Steryl ferulates composition of was investigated by high performance liquid chromatography-diode array detector-tandem mass spectrometry and high resolution tandem mass spectrometry in twenty-two millet samples and also in some fermented and microwave heated samples. Six compounds were found in Panicum, Pennisetum, Eleusine and Setaria genera, with a prevalence of campestanyl and sitostanyl ferulate. The lowest steryl ferulates content was found in Panicum, with values ranging from 2.98 ± 0.04 µg/g to 8.72 ± 0.41 µg/g. Foxtail millet and finger millet showed the highest amount with 46.07 ± 5.20 µg/g and 85.29 ± 4.30 µg/g, respectively. As for pearl millet, microwave heating and fermentation increased steryl ferulates by two (33.77 ± 0.88 µg/g) and five (75.83 ± 1.25 µg/g) times, with respect to the untreated sample. Microwave heating and fermentation could be used to increase steryl ferulates in millet.File | Dimensione | Formato | |
