Zusammenfassung: | The present disclosure is related to a process for obtaining a distilled alcoholic beverage (tequila) with antioxidant activity by the functionalization of the same by adding a walnut shell extract in a 5% tequila concentration which is subsequently stirred for 30 minutes at 250 rpm and passed through a muslin cloth to later filter the same through a thin pore paper filter. The antioxidant activity was evaluated by three different methods (ABTS +, DPPH and lipid oxidation inhibition) showing a great (96, 86 and 10% respectively) compared to commercial white and rested commercial tequilas. The results of the gas chromatography demonstrate that there is no modification in the profile of volatile compounds by the addition of the extract, while the sensorial analysis indicates that there is no difference in the acceptance of the tequila containing the extract or without the same. The results of the mass spectrometry indicate that in the nut shell extract, the main antioxidant compounds re ported in the same can be present (gallic acid, camaric acid, ellagic acid and catechin) and responsible for the antioxidant activity. This process proposes obtaining a distilled alcoholic beverage (tequila) with antioxidant activity by using an agro-industrial residue of great production in the country as a cheap and constant source of great capacity natural antioxidants.
Consiste en un proceso de obtención de una bebida alcohólica destilada (tequila) con actividad antioxidante mediante la funcionalización de la misma por adición de un extracto de cáscara de nuez en una concentración de 5% del tequila, que posteriormente se agita por 30 minutos a 250 rpm y se hace pasar por tela muselina para posteriormente filtrarla a través de una papel filtro de poro fino. La actividad antioxidante fue evaluada por tres métodos diferentes (ABTS+, DPPH e inhibición de la oxidación de los lípidos) demostrando una gran (96, 86 y 10 % respectivamente) comparada con tequilas blancos y reposados comerciales. Los resultados de la cromatografía de gases demuestran que no existe modificación en el perfil de compuestos volátiles mediante la adición del extracto, mientras que los análisis sensoriales indican que no existe diferencia de aceptación del tequila con extracto y sin extracto. Los resultados de espectrometría de masas indican que en el extracto de cáscara de nuez pueden estar presentes los principales compuestos antioxidantes reportados presentes en la cascara de nuez (ácido gálico, ácido |
