Starch granules contain an internal channel structure that can be used to encapsulate and deliver active ingredients such as nutrients, drugs, chemicals and microorganisms. Nature creates a broad range of starch granule sizes and compositions in different plants and this range of encapsulation matrices provides a great deal of commercial opportunity. Starch granules can be utilised for encapsulation in their native form or treated with amylases/amyloglucosidase to facilitate the entry of active ingredients into the granules. Interactions within the granules can be relatively passive or more structured in the form of complexes (such as amylose-lipid complexes). This mini-review evaluates this application of starch and potential commercial product opportunities.
