Beeswax. Beeswax (Cera alba, Cera flava) is a wax produced by honey bees (Apis mellifera) by means of their wax glands. Beeswax is obtained by melting honeycombs freed from honey with hot water. The melted honeycomb is cleaned until it is of food quality. It is approved in the EU under the number E 901 as a food additive.
