Shellac Lemon

Shellac is edible and it is used as a glazing agent on pills (see excipients) and candies in the form of pharmaceutical glaze (or, confectioner’s glaze). Because of its alkaline properties, shellac-coated pills may be used for a timed enteric or colonic release.^[12] It is also used to replace the natural wax of the apple, which is removed during the cleaning process.^{[13][dead link]} When used for this purpose, it has the food additive E number E904. This coating is not vegan and most likely not vegetarian either as it may, and probably does, contain crushed insects.
