“…In the last decade, subcritical water extraction (SWE) is being more and more implemented due to its excellent features. This technique, relying on heated and pressurized water, improves extraction efficiency due to lower solvent tension and viscosity, and improvement in solubility and mass transfer effects [24]. Moreover, SWE process does not consume organic solvents, making it more advantageous in terms of safety and compatibility with consecutive applications, environmental concerns and solvent recovery operations.…”

The aim of this study was to establish an efficient, sustainable technological procedure for valorization of food by-product, that is, cocoa bean shells (CBSs). The properties and stability of CBS extracts obtained by spray drying process with maltodextrin (MD) and whey protein (WP) as carrier agents were evaluated. For this purpose, phytochemicals of CBSs were extracted by subcritical water extraction. Physico-chemical properties, total phenolic (TP) and total flavonoid (TF) contents of the encapsulated extracts were determined in order to verify the efficiency of spray drying. Additional analyses for phytochemical characterization of the obtained powders were also performed. The efficiency of microencapsulation process was characterized by product recoveries higher than 58%. Both coating materials significantly influenced the encapsulation of phytochemicals in terms of rehydration, water solubility index and water absorption index, with WP being at an advantage. The best results for TP and TF contents were achieved when CBSs were encapsulated using WP (37.68 mg GAE/g and 7.66 mg CE/g, respectively). Microencapsulation using WP yielded higher content of gallic acid, caffeine, and theobromine than those with MD. According to the results, the formulation using 50% WP provided a better preservation of polyphenols compared to 50% MD. Therefore, spray drying with WP can be used as a method of choice for obtaining high quality CBS powders.

El presente trabajo, es una revisión que muestra el impacto que tiene el uso de las plantas medicinales en la salud humana. Desde la antigüedad, por tradición, se extendió el uso mayoritario de algunas familias vegetales como la Lamiaceae que destaca por sus propiedades aromáticas y aplicación culinaria en numerosas culturas, así como en el tratamiento y prevención de una gran variedad de enfermedades y malestares. Dentro de las especies pertenecientes a esta familia se encuentra el romero (Rosmarinus officinalis), planta que ha ganado importancia en el campo de la investigación por sus diversos atributos biológicos como: antiinflamatorio, antimicrobiano, antioxidante y anticancerígeno, entre otros; resultados que debe a sus metabolitos secundarios como: el ácido carnósico, el carnosol, el ácido rosmárico y el alcanfor, entre otros más, aunado a un potencial efecto cuando es aplicado. También se mencionan algunas metodologías que buscan la extracción de los componentes biológicamente activos del romero.

Vine-Canes as a Source of Value-Added Compounds for Cosmetic Formulations

et al. 2020

The majority of works about vine-canes are focused on the evaluation of their chemical composition and antioxidant potential. To the best of our knowledge, the possible applications of produced extracts in cosmetic formulations have never been explored. The aim of the present study was to evaluate the antioxidant properties of vine-canes subcritical water extracts for use as active ingredients in the cosmetic industry. For that, the phenolic content and antioxidant activity of six vine-cane varieties, namely Alvarinho and Loureiro from the Minho region and Touriga Nacional and Tinta Roriz (TR) from both the Douro and Dão regions, were evaluated through spectrophotometric and chromatographic methods. All extracts presented similar antioxidant activity and the highest phenolic content was reported for TR variety from the Douro region (33.7 ± 1.9 mg GAE/g dw). The capacity of vine-cane extracts to capture reactive oxygen species superoxide (O2∙−) was also studied, with the highest IC50 value being obtained for Loureiro variety (56.68 ± 2.60 µg/mL). Furthermore, no adverse effects on HaCaT and HFF-1 dermal cell lines in concentrations below 100 and 1000 μg/mL, respectively, were determined. Finally, Loureiro vine-cane extract was incorporated into a topical formulation, and physical and microbiological properties were within expected values, demonstrating that vine-canes extracts can be successfully incorporated in cosmetic products.
