Physico-chemical properties of edible films derived from native and phosphated cush-cush yam and cassava starches

Edible, biodegradable films based on native and phosphated cush-cush yam and cassava starches plasticized with glycerol were developed by casting. The starches were chemically modified by cross-linking with sodium trimetaphosphate (STMP). The physicochemical properties of each of the different starc...
