Provided are methods or processes for producing ferulic acid from a plant material, for example, a rice bran or its derivatives. Provided are methods comprising an ion swapping and solvent extraction process followed by a chromatographic separation operations that are coupled into a process which functions to recover a fraction rich in gamma-oryzanol, thus enabling the subsequent production of a high purity ferulic acid. Provided are methods comprising an ion swapping and solvent extraction process followed by a process which functions to recover a fraction rich in gamma-oryzanol, or a mixture of ferulic acid esters of phytosterols and triterpenoids, optionally comprising cycloartenyl ferulate, 24-methylenecycloartanyl ferulate, and/or campesteryl ferulate, to enable the production of a high purity ferulic acid. Provided are methods comprising a saponification and solvent extraction process followed by recovering a fraction rich in gamma-oryzanol to enable the production of a high purity ferulic acid.

Methods for the production of ferulic acid

Provided are industrial processes for producing an organic acid alky ester from a feedstock containing organic acids and/or saponifiables, comprising: countercurrently contacting a feedstock with an organic alkylating reagent over two or more vessels or stages at temperature between 100° C. and 400° C. and pressure between 0.1 barg and 355 barg while simultaneously removing water and/or glycerin with unreacted alkylating reagent from the final vessel or stage to result in a first reaction method product containing organic acid alkyl esters, followed by a choice of using the alkyl esters as-is, purifying the organic acid alkyl esters from the first reaction product mixture or subjecting the first reaction product mixture to an additional transesterification reaction to convert saponifiables into additional organic acid alkyl esters, then purifying the organic acid alkyl esters from this second reaction method product.
