SYNTHESIS OF CAFFEIC/FERULIC ACID ESTERS FROM CHLOROGENIC ACIDS CONTAINED IN COFFEE AND BY-PRODUCTS FROM SAID INDUSTRY

The present invention relates to the enzymatic synthesis of hydroxycinnamic acid esters (caffeic, ferulic, and p-coumaric acid) in free reaction systems using nonpolar solvents from chlorogenic acids present in by-products and co-products of the coffee industry. Said products consist of green beans,...

Beschreibung
Zusammenfassung:	The present invention relates to the enzymatic synthesis of hydroxycinnamic acid esters (caffeic, ferulic, and p-coumaric acid) in free reaction systems using nonpolar solvents from chlorogenic acids present in by-products and co-products of the coffee industry. Said products consist of green beans, decaying beans, husks, pulp, parchment, among others, generating hydroxycinnamic acid esters. Said esters are obtained in a single reactor after its extraction from raw materials, such as by-products of the coffee industry, using systems free of chlorogenic solvents for transforming it directly into an ester of caffeic acid, ferulic, or p-coumaric by a free enzyme catalyst or by immobilizing. The reaction product is purified or enriched by evaporation. Also, said esters allow taking advantage and enhancing the raw materials generated during the coffee benefit process and incorporated into oil-based products for the cosmetic, food, and agricultural industry. La presente invención se relaciona con la síntesis enzimática de ésteres de ácidos hidroxicinámicos (ácido cafeico, ferúlico y p-cumárico), principalmente cafeico, en sistemas de reacción libres del uso de solventes apolares a partir de los ácidos clorogénicos presentes en subproductos y/o coproductos de la industria de café, como granos verdes granos en descomposición, cascarilla, pulpa, pergamino, entre otros. Mediante esta invención la generación de ésteres de ácidos hidroxicinámicos se puede realizar en un solo reactor después de su extracción a partir de materias primas crudas, como los subproductos de la industria del café, empleando sistemas de reacción libres de solventes clorogénicos, para posteriormente transformarlo directamente en un éster de ácido cafeico. Ferúlico o p-cumárico mediante el uso de un catalizador enzimático libre o inmovilizando. Por último, el producto de reacción puede ser purificado o enriquecido por evaporación. Los ésteres de ácidos hidroxicinámicos generados mediante el proceso anterior permiten aprovechar y valorizar las materias crudas generadas durante el proceso de beneficio del café y además pueden incorporarse a productos base oleosa de interés para la industria cosmética, alimentaria y/o agrícola.
