Abstract: The invention provides a process for the production of a biomass hydrolysate suitable for the production of levulinic acid and formic acid, a biomass hydrolysate obtainable by said process, a process for the production of levulinic acid and formic acid from said biomass, and levulinic acid and formic acid obtainable by said process. The hydrolysis process includes a single hydrolysis step wherein a slurried biomass is subjected to a temperature of between 120 and 200° C., preferably between 160 and 190° C., for a time period of between 2 and 8 hours, preferably between 20 and 140 minutes at a mineral acid concentration of between 1-15 wt %. The process can be carried out starting from lignocellulosic biomass, and also from glucose and fructose.
