Use of response surface methodology to compare vacuum and atmospheric deep-fat frying of papaya chips impregnated with blackberry juice
Utilización de la metodología de superficie de respuesta para comparar la fritura por inmersión a presión atmosférica y al vacío de hojuelas de papaya impregnadas con jugo de mora
Vacuum and atmospheric deep-frying were employed to obtain blackberry-based snacks using unripe papaya as matrix. Papaya slices were osmotically impregnated with blackberry juice and fried between 126°C and 154°C at ...
Concentration of Polyphenolic Compounds in Blackberry (Rubus Adenotrichos Schltdl.) Juice by Nanofiltration
Nanofiltration membranes with molecular weight cut‐off around 200 Da were evaluated to concentrate anthocyanins and ellagitannins in a blackberry juice. Temperature was 30°C and cross‐flow velocity 0.3 m/s. Transmembrane ...
Hypoglycaemic, hypolipidaemic and antioxidant effects of blackberry beverage consumption in streptozotocin-induced diabetic rats
Abnormal glucose metabolism, hyperlipidaemia profiles and high levels of radical oxygen species (ROS) are classic features of diabetes. This study evaluates the effect of the consumption of two different blackberry beverages ...

Method for obtaining an extract rich in ellagic acid tannins from fruits that contain these compounds, and resulting extract
La presente invención se relaciona con el campo de la biotecnología y con los procesos que emplean tecnologías membranarias, y en particular se refiere a un método para la obtención de un extracto enriquecido en taninos ...
Key odor and physicochemical characteristics of raw and roasted jicaro seeds (Crescentia alata K.H.B.)
Jicaro seeds (Crescentia alata) are widely consumed in Central America, primarily as a popular tasty and nutritious beverage called “horchata”. Seeds are roasted to develop a specific aroma through a process that has never ...
Physicochemical and antioxidant composition of fresh peach palm (Bactris gasipaes Kunth) fruits in Costa Rica
Composição físico-química de frutos de pupunha (Bactris gasipaes Kunth) na Costa Rica
The variability of the physicochemical composition, carotenoid and polyphenol contents and hydrophilic antioxidant capacity of fresh peach palm (Bactris gasipaes) fruit was studied with a view to its exploitation as a ...
An untargeted metabolomic assessment of cocoa beans during fermentation
Fermentation is a critical step in the processing of high quality cocoa; however, the biochemistry behind is still not well understood at a molecular level. In this research, using a non-targeted approach, the main metabolomic ...
Procedimiento para la preparación de jugo de noni
Se refiere a un procedimiento de preparación de jugo de noni que comprende etapas de: a) triturado de los frutos de noni cuando están en estado de madurez blanco translúcido para producir un puré de frutos de noni; b) ...
Innovative process combining roasting and tempering to mechanically dehull jicaro seeds (Crescentia alata K.H.B)
An innovative process combining roasting and tempering was proposed to promote puffing and mechanical dehulling of jicaro seeds. Roasting was performed at three temperatures (120 °C, 140 °C, and 160 °C) and for six residence ...
Effects of mechanical and enzymatic pretreatments on extraction of polyphenols from blackberry fruits
This study evaluated the effects of mechanical and enzymatic pretreatments on the extraction of anthocyanins and ellagitannins from blackberries. Continuous pressing yielded significantly higher turbidity values and content ...
