Abstract:

Anthocyanins microcapsules from Acanthopanax.sessiliflorus (Rupr. et Maxim.) Seem were prepared by Spray-Drying, using maltodextrin and gum arabic as wall materials. The stability and releasing property of anthocyanins microcapsules were studied. Using the retention rate as evaluation index, the effects of temperature, light, pH and metal ions on the stability of microcapsules and anthocyanins during 30 days storage were assessed, and samples were taken every five days. Results show that the microcapsules have greater storage stability against temperature, light, pH and metal ions. Using the release rate as evaluation index, the effect of releasing of microcapsules was evaluated, and samples were taken every 30min. Results show that the microcapsules have certain slow-release effect.
