A thermally treated, encapsulated plant extract obtained by the method comprising:
- a) extracting a plant-based raw material containing safranal, wherein the plant-based raw material is selected from the group consisting of Crocus sativus, Centaurea sibthorpii, Centaurea consanguinea, Centaurea amanicola, Erodium cicutarium, Chinese green tea, Calycopteris floribunda, Crocus heuffelianus, Sambucus nigra, Gardenia jasminoides, Citrus limon, Cuminum cyminum L., and Achillea distans with an extraction solution at an acidic pH in the range from 3 to 5 to provide a liquid extract containing at least 0.2% of safranal by weight as measured by HPLC;
- b) impregnating the liquid extract onto a bulking agent selected from the group consisting of maltodextrin, sugars, silica, and acacia gum to form an encapsulated plant extract;
- and
- c) subjecting the encapsulated plant extract to thermal treatment.
