There are three common methods for meat removal from bone. One method is boiling to cook the meat from the bone. Another method used is called maceration.
Maceration is the soaking of bone in liquid to decompose the flesh with bacteria.
The third common method is the use of dermestid beetles to eat the meat from the bone. The method used depends on the condition of the bone and how fragile it is. Once the meat has been removed, the bone must be cleaned, whitened and sealed. This is done with detergents, solvents and wax. Chlorine bleach should not be used at all in this process.
