Abstract: Nutritional supplement, feed formulation and methods to improve the efficiency of meat production of a bovine animal, using ethyl ferulate as a nutritional supplement; where the administration of ethyl ferulate at bovine animal, is premixed with an excipient food grade, feed formulation, balanced food, concentrated food, and the like. The ethyl ferulate administration is daily during the final stage of fattening bovine animal, wherein the final stage of fattening is 20 to 40 last days.

Abstract: Method for extracting ferulic acid and/or its salts from a previously conditioned source rich in ferulic acid and its salts which comprises adsorbing the ferulic acid and/or its salts on a column packed with synthetic resin, desorbing the ferulic acid and/or its salts using an organic solvent, separating the liquor rich in ferulic acid into two fractions according to their water content, separately concentrating the two liquor fractions, mixing and concentrating said fractions, adding 2 volumes of water to them, concentrating the mixture obtained, separating out the insoluble impurities by sedimentation, pre-crystallizing the ferulic acid and/or its salts with a synthetic purification resin, crystallizing out the ferulic acid and/or its salts, separating the ferulic acid and/or its salts from the crystallization mother liquors and drying it and screening it.

Abstract: Methods to purify ferulic acid and/or salts thereof, both in solid state as in solution, the methods include: dissolve the ferulic acid, with a selective organic solvent, recover and isolate the solution from the insoluble impurities with filters; recover the organic solvent evaporating the solution; mix the concentrated extract of ferulic acid with water to pre-crystallize the hydrosoluble impurities; evaporate the mixture to remove the remains of the organic solvent; concentrate the mixture free of solvent in an evaporator; cool the mixture down to 40° C.; let the concentrated mixture set for 1 h, to then isolate by sedimentation the water-insoluble impurities; re-heat the mixture free of impurities to 70° C.; purify the mixture through a synthetic resin, transfer the purified mixture to a crystallizing container to crystallize the ferulic acid; remove the mother liquor of crystallization of the precipitate of ferulic acid; dry the ferulic acid.
