Edible carboxymethyl cellulose films containing natural antioxidant and surfactants: α-tocopherol stability, in vitro release and film properties

Edible carboxymethyl cellulose films containing α-tocopherol (TC) and a mixture of polysorbate 80 (T80) and lecithin were prepared and characterized physicochemically. The stability of TC into the CMC matrix over time, the physicochemical properties of the films, in vitro release profile of TC from films and its antioxidant capacity were investigated. Films containing each one or both surfactants were more homogenous and no phase separation was...
