Thermal analysis and physiological behavior of cellulose/pectin complex from Canna edulis Ker by-product

► Three cellulose/pectin complexes were obtained from Canna by-product. ► Thermal characteristics of the three complexes were studied. ► The three complexes inhibited gastric pepsin and lipase enzymatic activities. ► The three complexes inhibited the hydrolysis of β-lactoglobulin and tributyrin. ► The three complexes could be used as additives in the food industry.
