Effect of encapsulated edible halophyte with different biopolymers on the inhibition of sodium absorption in mouse

Abstract The purpose of this study was to investigate the effects of edible halophyte Salicornia herbacea encapsulated with biopolymers on inhibition of sodium absorption in mouse. Salicornia herbacea encapsulated with four biopolymers (pectin, chitosan, cellulose and dextrin) were fed to mice for 48 hr, and inhibiting sodium absorption was measured. In primary in vitro condition, fresh Salicornia herbacea encapsulated with 1% cellulose had 40% binding rate. Juice residue Salicornia herbacea encapsulated with 1% chitosan had the highest sodium binding rate by 50%. In mouse model, fresh, juice, and juice residue of Salicornia herbacea encapsulated with 4% chitosan had the highest sodium absorption inhibitory rate by 19%. These results indicate that biopolymer‐encapsulated Salicornia herbacea could be combined with sodium under in vitro condition, and Salicornia herbacea encapsulated with biopolymers reduced sodium absorption in a mouse model. Chitosan and cellulose had the highest sodium absorption inhibitory effects compared with the other biopolymers.
