蜂蜡

Beeswax is a natural wax that is formed from honeybee Apis mellifera. It is a lipid that contains hydrocarbons, esters and free acids, which can be used to lower the transference of water on films.

Beeswax is used to produce edible films (sodium caseinate, soy protein isolate etc.). It can form a mixture with a variety of fatty acids and polyols to provide flexibile, elastic and stretchable films. It also decreases the water vapor permeability and enhances the mechanical properties of the film.
