Effect of the potassium sorbate and carvacrol addition on the properties and antimicrobial activity of tapioca starch – Hydroxypropyl methylcellulose edible films

Tapioca starch (TS), hydroxypropyl methylcellulose (HPMC), and glycerol (GLY) based edible films with the addition of potassium sorbate (KS) and carvacrol (CARV) were prepared by casting technique. The effect of antimicrobial concentrations on the color, mechanical properties, solubility in water (S...
