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.

The invention relates to a food supplement and to a method for improving the meat production efficiency in a bovine animal by means of ethyl ferulate. For the administration of the food supplement to the bovine, the ferulate is pre-mixed with a feed-grade excipient, and it is administered daily, added to food, during the final fattening stage, which lasts between 30 and 40 days.

The present invention comprises a natural method of feed supplement to beef cattle, with a maiz extract obtained from the nixtamalization process with a high content of ferulic acid and its salts, for a period of 30 days in the final phase of the feedlot. Use of this dietary supplementation enables an increase in carcass yield and meat quality is not negatively affected as with a commercial ß-agonist. In addition to the above effects, the effective supplementation of ferulic acid to cattle, showed to have antioxidant effects on fresh meat during its shelf life, which can lead to great benefits for the industrial meat market.
