Green and clean modification of cassava starch – effects on composition, structure, properties and digestibility

Abstract There is a growing need for clean and green labeling of food products among consumers globally. Therefore, development of green modified starches, to boost functionality, palatability and health benefits while reducing the negative processing impacts on the environment and reinforcing consumer safety is in high demand. Starch modification started in mid-1500s due to the inherent limitations of native starch restricting its commercial applications, with chemical modification being most common. However, with the recent push for “chemical-free” labeling, methods of physical and enzymatic modification have gained immense popularity. These methods have been successfully used in numerous studies to alter the composition, structure, functionality and digestibility of starch and in this review, studies reported on green modification of cassava starch, one of the most common utilized starches, within the last ten years have been critically reviewed. Recent research has introduced starch as an abundant, natural substrate for producing resistant starches through biophysical technologies that act as dietary fiber in the human body. It is evident that different techniques and processing parameters result in varying degrees of modification impacting the techno-functionality and digestibility of the resultant starch. This can be exploited by researchers and industrialists in order to customize starch functionality in accordance with application.
