Optimum extraction conditions of anthocyanins from petals of saffron (Crocus sativus) using acidified ethanol as the solvent were revealed. The investigated factors were solvent to sample ratio (20:1–80:1), ethanol concentration (%), extraction temperature (25–45 °C), and time (8–24 h). Response surface methodology with Box–Behnken design was applied to determine optimum processing conditions leading...
In this work, anthocyanin stability and color of encapsulated freeze-dried saffron petal's extract with various matrices consisting gum Arabic (AG) and maltodextrin (M7 and M20) were studied. Total anthocyanins of powders and color parameters (a*, b*, L*, C, H° and TCD) were measured immediately after production and during storage up to 10 weeks by pH differential method and computer vision, respectively...
