Bating is a step in leather making in which raw hides, after the hair has been removed with lime, are treated with proteolytic enzymes so that the finished leather turns out soft, supple and free of leftover lime. Tanners once did this with a bath made from hen or pigeon manure, a close relative of puering, which used dog faeces, and the bacteria and enzymes in the bath acted on the collagen of the skin over a few days. Early inventors tried to replace it with artificial bates such as old lime liquors neutralized with sulphuric acid. Industrial pancreatin, produced from the 1890s, ended puering, and papain from papaya latex and microbial enzymes now do the work. It is described as the one stage of modern tanning that chemical agents cannot replace.
