Description
Inmaculada Criado-Navarro and four co-authors compare ways to dry saffron petals without losing their useful chemistry, in a 2024 study. The petals are a leftover of spice production and spoil fast, yet they hold valued compounds such as flavonols and the pigments called anthocyanins. Drying is the step that decides whether those compounds survive storage.
Three methods faced off: oven heat at two temperatures, freeze-drying, and vacuum evaporation at two temperatures. Extracts from each batch were profiled, turning up twenty-two metabolites. Hot oven drying best preserved rare, precious traces like safranal, the scent compound. Vacuum drying and freeze-drying kept the most flavonoids. The paper gives producers a drying choice matched to which compound they want.
