description | Se presenta un procedimiento de obtención de extractos antioxidantes a partir de macroalgas empleando extracción acuosa en continuo y asistida por ultrasonidos. El proceso se puede realizar sobre alga fresca o sobre alga seca, tras una resuspensión en agua. Se prepara una suspensión de alga en agua con una concentración de sólidos entre un 10 y un 30%. La mezcla se alimenta a un sistema de ruptura ultrasónica. El extracto es filtrado y liofilizado, obteniéndose concentraciones de polifenoles totales de 62.4 mg eq. de floroglucinol/ g de liofilizado con Bifurcaria bifurcata y 44 mg eq. de floroglucinol/ g de liofilizado con Ascophyllum nodosum. El extracto se puede emplear como ingrediente en formulaciones cosméticas y alimentarias.
The invention relates to a method for obtaining antioxidant extracts from macroalgae using ultrasound-assisted continuous aqueous extraction. The process can be performed using fresh alga or dry alga, after resuspending same in water. A suspension of alga in water is prepared with a solid concentration of between 10 and 30%. The mixture is fed to an ultrasonic disruption system. The extract is filtered and lyophilized, obtaining total polyphenol concentrations of 62.4 mg eq. of phloroglucinol/g of lyophilisate with Bifurcaria bifurcata and 44 mg eq. of phloroglucinol/g of lyophilisate with Ascophyllum nodosum. The extract can be used as an ingredient in cosmetic and food formulations. |
