A levulinic acid composition A having: a. at least 95 wt. % of levulinic acid; b. between 5 wppm and 5000 wppm of formic acid; and c. less than 1000 wppm of angelica lactone, based on the total weight of the composition. A process for the isolation of a levulinic acid composition, having the following steps: a. performing acid catalyzed hydrolysis of a C6 carbohydrate-containing feedstock to obtain reaction product X, b. subjecting of reaction product X to solid-liquid separation to provide a composition 1, c. feeding composition 1 to at least two purification steps to treat composition 1 to obtain a levulinic acid composition, wherein a second or a further purification step is a melt crystallization step.
