Abstract Studies regarding the bioactivity of teas are mainly based on the phenolic composition and in vitro antioxidant activity of the herbal species used in their preparation. The aim of this study was to compare the in vitro and ex vivo antioxidant activity, cytotoxic/antiproliferative activity against cancer cells, the inhibitory activity of α-amylase, α-glucosidase and angiotensin I-converting enzymes, as well as the inhibition of DNA-induced fission of the peroxyl radical, in relation to ...

Abstract Pile-fermentation is the most important process of producing ripened pu-erh tea. To study the chemical changes of tea leaves during pile-fermentation (PF), liquid chromatography coupled with tandem mass spectrometry (LC-MS) was used. Untargeted metabolomics analysis revealed that the first stage of PF is crucial in transforming the original secondary metabolites, whereas the contents of flavan-3-ols and gallic acid were decreased after long-term PF. Targeted metabolomics analysis indica...

Abstract Camu-camu (Myrciaria dubia) seeds are discarded without recovering the bioactive compounds. The main aim of the present work was to optimise the solvent mixture to extract higher total phenolic content and antioxidant capacity of camu-camu seeds. The optimised solvent system increased the extraction of phenolic compounds, in which vescalagin and castalagin were the main compounds. The optimised extract displayed antioxidant capacity measured by different chemical and biological assays, ...

Abstract Background Phenolic compounds have been studied for a variety number of bioactivities using in vitro, ex vivo, and in vivo protocols. Most of the studies dealing with phenolic compounds deal with in vitro antioxidant, antihypertensive, anti-inflammatory, antipyretic, antihemolytic effects in human erythrocytes, hypolipidemic, and antiproliferative activities. Scope and approach Companies have used the overall understanding of the beneficial effects of polyphenols to develop “functional”...

This study aimed to model the inactivation of Lactobacillus brevis DSM 6235 while retaining the viability of yeasts during washing brewer's yeast with phosphoric acid and chlorine dioxide. The independent variables in the acid washing were pH (1-3) and temperature (1-9 degrees C), whereas in the washing with chlorine dioxide, concentration (10-90 mg/L) and temperature (5-25 degrees C) were assessed. The predictive models obtained for the four response variables gammaLA, gammaCl (decimal reductio...

Abstract The effect of ohmic heating voltage gradient (OH, 8, 12, 16, 20, and 24 V cm-1, 72 - 75 °C/15 s) on the physicochemical characteristics (partial and total hydroxymethylfurfural (HMF) levels, whey protein nitrogen index (WPNI), color parameters, and water mobility), and on the volatile profile of infant milk formulas (IF) was investigated. The OH-treated samples presented the lower formation of free and total HMF, higher whiteness index, and lower viscosity, indicating good preservation ...

ABSTRACT This work aimed to characterize the phenolic composition and in vitro antioxidant and antiproliferative properties of lyophilized camu-camu (Myrciaria dubia) seed extract (LCE), and to assess the effects of LCE on the antioxidant and sensory traits of yogurt. The LCE contained 46.3% (wt/wt) total phenolic content; the main compounds quantified were vescalagin, castalagin, gallic acid, procyanidin A2, and (−)-epicatechin. The LCE had antioxidant activity, as measured by different chemica...

Abstract The purpose of this study was to use a statistical approach to optimise the experimental conditions regarding the extraction of bioactive compounds, and to analyse the in vitro functional properties of crude lyophilized extracts (CLE) and partially purified (PPE) extracts of Clitoria ternatea petals. The results showed that the factors of temperature and time influenced the extraction of phenolic compounds, antioxidant activity and the physicochemical parameters. Simultaneous optimisati...

ABSTRACT The consumption of probiotic-enriched dairy products has been associated with many health benefits, including anti-hyperglycemic activity. The effect on health is dependent on the type of probiotic culture used and the dairy product consumed. This study evaluated the effect of different probiotic-enriched dairy matrices (Minas Frescal cheese, Prato cheese, and whey dairy beverage) containing Lactobacillus casei on in vitro and in vivo anti-hyperglycemic activity. For this purpose, in vi...
