Popis:	The self-heating of moistened hay beyond 70°c, the maximum temperature reached by thermophilic micro-organisms, was studied under temperature-controlled conditions. The pH decreased on heating from 6·2 to 3·8. Fructosan was rapidly degraded to fructose, which then also decreased. More hemicellulose than cellulose was broken down and the resulting products, monomers and polymers of pentose and glucose, increased correspondingly in aqueous extracts; hay self-heated to 165°c, contained little free sugar, and pentose polymers were the only remaining soluble carbohydrates. Hay incubated with water at 80°c, showed changes similar to hay self-heated between 70 and 100°c.
