Phenolics present in the free, esterified, glycosylated and insoluble-bound forms of araticum pulp, peel seed were for first time characterized quantified using HPLC-ESI-MS/MS. Levels total phenolics, flavonoids, condensed tannins antioxidant activities from fruit followed order > pulp seed. Overall, esterified phenolics dominant parts highest contributors to their activities. Extracts found contain contrasting levels that specific each part. From 10 fruit, catechin epicatechin major ones...
In this work, we investigated the effects of nominal ultrasonic power (160-640 W) and process time (0.5-5.0 min) on phenolic compounds recovery antioxidant activity from araticum peel. The individual synergistic variables were estimated using a full factorial experimental design. Operating at high powers was possible to obtain yields activities short times (≤5 min). HPLC-ESI-QTOF-MS/MS analysis revealed that peel sample possessed 142 phytochemicals, 123 which had not been reported in...
Soluble carbohydrates, volatile and phenolic compounds from calabura fruit as well its antioxidant activity were assessed. The low amount of fermentable oligo-, di-, monosaccharides polyols (FODMAPs) similar glucose fructose allow us to classify the berry low-FODMAPs. terpenes β-Farnesene dendrolasin identified by SPME-GC-MS major components. UHPLC-MS/MS analysis revelled gallic acid (5325 μg/g dw) cyanidin-3-O-glucoside (171 main compounds, followed gentisic acid, gallocatechin, caffeic...
The Eugenia calycina Cambess, also known as pitanga-do-cerrado, is an unexplored Brazilian fruit used by native people for the treatment of diabetes. aim this study was to identify phenolic compounds from leaves, pulp and seed using LC-MS-based targeted untargeted analysis. quantitative analysis showed a high content in all plant parts which ellagic acid main compound with values 8244.53 µg/g dw (leaves), 5054.43 (pulp) 715.42 (seed). total 20371.96, 7139.70 2204.75 dw, respectively. In...
Iridoid blue-based pigments can be found in fruits of genipap (Genipa americana L.). Besides being a potential source natural blue colorant the food industry, they have also been associated with pharmacological effects. Therefore, recovery iridoids by ultrasound-assisted extraction from both unripe and ripe was analysed UPLC-DAD-ESI-(-)-QTOF-MS/MS. Nine were identified their exact masses fragmentation pattern, namely geniposidic acid, gardenoside, genipin-1-β-gentiobioside, geniposide,...
Grumixama (Eugenia brasiliensis Lam.) are red-colored fruits due to the presence of anthocyanins. In this paper, anthocyanin-rich extracts from grumixama were submitted different temperatures and light irradiations, with aim investigating their stabilities. The thermal stability data indicated that a temperature range 60 80 °C was critical anthocyanins extracts, quotient value (Q10) 2.8 activation energy (Ea) 52.7 kJ/mol. showed highest during exposure incandescent irradiation (50 W),...
Peach palm (Bactris gasipaes Kunth) is an amazonian fruit in which its peel has been appointed as a carotenoid-rich byproduct with biological properties. For analytical purposes, carotenoids are frequently extracted by non-green (use of toxic organic solvents) and time-consuming methods, can affect the quality (carotenoid profile) safety extracts for direct food applications. We investigated herein effect different extraction methods on individual carotenoid profile peach peels HPLC-DAD....
This study evaluated the effect of ethanol concentration (EC, 0–70%) and temperature (25–75 °C) on oligosaccharides extraction from ripe banana pulp, as well profile mono-, di-, galacto-, fructo-, malto- xylooligosaccharides in pulp peel. According to response surface plots, EC 52% (vol/vol) 75 °C provided maximum pulp. High-performance anion exchange chromatography coupled pulsed amperometric detection showed presence glucose, fructose, sucrose, maltose, arabinose, 1-kestose, xylopentaose,...
We evaluated the effect of ultrasonic power (200–600 W) and process time (1–7 min) on recovery a novel polysaccharide from mutamba (Guazuma ulmifolia Lam.) seeds applying high-intensity ultrasound. Ultrasound conditions intensification gradually was removing mucilage layer around hydrated seeds. Then, scanning electron micrographs showed that removed completely at highest applied energy density (10,080 J/mL). Although colour seed (MSM) have been changed due to increase density, it not...
This study covers the proximate and phytochemical composition of mutamba (Guazuma ulmifolia Lam.) fruit. fruit showed high dietary fibre (36.9%) low moisture (10.0%) contents which justify its hardness dryness. Nevertheless, this is very appreciated due to sweet pulp (high sucrose content, 16.3%) attractive taste. The soluble insoluble-bound phenolic compounds from were analysed by using liquid chromatography coupled tandem mass spectrometry (LC-MS). LC-MS identified 26 compounds. Mutamba...
Araticum (Annona crassiflora Mart.) is a native fruit from Brazilian Cerrado widely used by folk medicine. Nevertheless, the biological effects of its seeds and peel have not been extensively evaluated. We evaluate herein antioxidant, antiproliferative healing potential araticum extracts. HPLC-ESI-MS/MS analysis showed flavonoids, namely epicatechin quercetin, as main compounds in extracts, respectively. These extracts high content phenolic (7254.46 97.74 µg/g extract) and, consequence,...
Abstract Homogenizer‐assisted extraction (HAE) was employed in the recovery of total phenolic compounds (TPC) from banana peel. The effects ethanol concentration (20–70%, v/v, EC) and solid–solvent ratio (2.5–7.5%, w/v, SSR) on TPC peel were evaluated using response surface methodology. best conditions defined as 54% (v/v) 7.5% (w/v). HAE optimum able to extract a high content (2.44 g GAE/100 dw) with just 30 s extraction. In addition, showed antioxidant activity different assays used (DPPH...
Inulin is a prebiotic carbohydrate widely used in the food industry due to its health-related claims and ability modify/improve technological properties of products. However, industrial processes such as thermal treatments, can cause structure changes carbohydrates affecting their health benefits properties, but these aspects have received little attention. Therefore, this study aimed evaluate impact treatments (70–100 °C/60 s) on inulin chemical stability dairy system, araticum flavoured...
Folin-Ciocalteu (F-C) is a routine assay in several laboratories around the world and has been widely employed for total phenolic content (TPC) quantification from food samples. F-C was modified to obtain system reaction safer, as well decrease use of reagents, energy expenditure time-consuming. After evaluating alternatives solvents supports, effect binomial time/temperature, follows: 40% ethanol solvent, 20 minutes at room temperature (25±2°C) using 50% reagent 5% sodium carbonate...
