A process for a reactive extraction and subsequent purification of organic molecules from biomass comprises extracting one or more products from the biomass using an extraction solvent to solvate the products, contacting the biomass with a reactant during the extracting, recovering the one or more products, performing ultrafiltration to remove impurities from the one or more products to produce a filtered extract, extracting oils in the filtered extract using adsorption to produce a de-oiled extract, performing transesterification or hydrolysis on the de-oiled extract, and performing adsorptive purification on the ferulic acid, coumaric acid, ferulate, coumarate, or a combination thereof. The one or more products comprise extracted organic molecules comprising a ferulate or a coumarate, and the one or more products are separated from the biomass as a liquid extract.

A process for efficient purification of magnesium lactate from fermentation broths derived from non-homogeneous feedstocks that contain soluble and insoluble impurities is provided. The fermentation broth, having high amounts of impurities and containing magnesium lactate in a soluble form, is separated from insoluble impurities, concentrated to particularly high concentrations of the magnesium lactate at elevated temperatures, and subsequently cooled by gradual and controlled cooling such that magnesium lactate crystals of high purity are formed.
