Comparative study of encapsulated rhizome extract of Alpinia purpurata (Zingeberaceae) in alginate and alginate-chitosan

Encapsulation is a coating process of bioactive compound. Alpinia purpurata has been well known as lengkuas merah an Asian tropical herbal which contain phenylpropanoid, phenolic and flavonoid. Phenolic and flavonoid compounds is an agent that can be used as anti cancer. This research aim is to create a product of Alpinia purpurata extract which encapsulated in alginate or alginate-chitosan. Theproduct of encapsulated has been observed towards SEM ( Scanning Electron Microscophy) and spectrocophy Infra-Red method. Encapsulated product of lengkuas merah extract made through extrusion method in alginate and chitosan with ratio 1:1 (w/w) then dripped in 2% CaCl2.The Alpinia purpurata/alginate/chitosan microcapsules (APCAM) is better than alginate microcapsules (APAM)
