Want to know what this unlabeled coating on our food is?
Dude, That Isn’t Wax On Your Apple! (realitybloger.wordpress.com)
What if I told you that cow, pig, and chicken collagen is now used in place of wax on your fruits and vegetables, among many other things much worse than you can probably imagine? . . . [and] all approved by the FDA. (Source)

Shellac: a resin secreted by the female lac bug.
Mmmmmmm, bug gooo, yummie.
Shellac is a resin secreted by the female lac bug, on trees in the forests of India and Thailand. It is processed and sold as dry flakes which are dissolved in ethyl alcohol to make liquid shellac, which is used as a brush-on colorant, food glaze and wood finish. Shellac functions as a tough natural primer, sanding sealant, tannin-blocker, odour-blocker, stain, and high-gloss varnish. Shellac was once used in electrical applications as it possesses good insulation qualities and it seals out moisture. Phonograph (gramaphone) records were also made of it during the pre-1950s, 78-rpm recording era.
Shellac is one of the few historically appropriate finishes (including casein paint, spar varnishes, boiled linseed oil and lacquer) for early 20th-century hardwood floors, and wooden wall and ceiling paneling.
From the time it replaced oil and wax finishes in the 19th century, shellac was one of the dominant wood finishes in the western world until it was replaced by nitrocellulose lacquer in the 1920s and 1930s.
