Functional properties of coffee and coffee by-products
Coffee, one of the most popular beverages, is consumed by millions of people every day. Traditionally, coffee beneficial effects have been attributed solely to its most intriguing and investigated ingredient, caffeine, but ...
Characterization of phenolic compounds in jocote (Spondias purpurea L.) peels by ultra high-performance liquid chromatography/electrospray ionization mass spectrometry
Phenolic acids and flavonol O-glycosides were extracted from the peels of jocote fruits (Spondias purpureaL.,Anacardiaceae) harvested in Costa Rica and characterized using ultra high-performance liquid chromatog-raphy ...
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 ...
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 ...
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 ...
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 ...
Exploring new alleles involved in tomato fruit quality in an introgression line library of solanum pimpinellifolium
We have studied a genomic library of introgression lines from the Solanum pimpinellifolium accession TO-937 into the genetic background of the “Moneymaker” cultivar in order to evaluate the accession’s breeding potential. ...
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 ...
Bean (Phaseolus Vulgaris) Treatments Effect on Starch Digestible Fractions and Consumer Acceptability in the Production of Bean Wheat Cookies
The effect of bean (Phaseolus vulgaris L) treatment (raw bean flour, RBF, soaked bean gruel, SBG, and soaked and cooked bean paste, SCBP) in wheat composite cookie production on starch digestibility and consumer ...
Pasteurization of blackberry juice preserves polyphenol-dependent inhibition for lipid peroxidation and intracellular radicals
Berries are commonly consumed as juice, and juice-processing conditions could affect their bioactive compounds. This study evaluated the effect of thermal treatments on the antioxidant capacity of blackberry juice polyphenols. ...
