This study aimed to evaluate the antioxidant, anti-inflammatory, and cytotoxic properties phenolic composition of peel seed avocado varieties Hass Fuerte using green solvents. Ethanol soluble compounds were identified in both HPLC-MS/MS quantified HPLC-DAD. Agro-industrial by-products exhibited high radical scavenging activity against synthetic free radicals (DPPH ABTS) reactive oxygen species (peroxyl, superoxide, hypochlorous acid) ability reduce Fe3+ Fe2+. The main with significant...
Vegetables are widely consumed in Brazil and exported to several countries. This study was performed evaluate the phenolic content antioxidant activity of vegetables commonly using five different methods, namely DPPH ABTS free radical, β-carotene bleaching, reduction Fe3+ (FRAP), oxidative stability Rancimat, chemical composition gas chromatography-mass spectrometry (GC-MS). The compounds ranged from 1.2 mg GA/g (carrot) 16.9 (lettuce). presenting highest were lettuce (77.2 µmol Trolox/g...
Purification and bioassay-guided fractionation were employed to isolate proanthocyanidins with antioxidant activity from peanut skin (Arachis hypogaea Runner 886). The crude extract was prepared acetone (60% v/v) purified using chromatographic methods, including a semipreparative HPLC technique. As result, two isolated identified NMR, epicatechin-(2 β → O 7, 4 8)-catechin (proanthocyanidin A1) epicatechin-(β 2 8)-epicatechin A2). Despite the structural similarity, differences observed in...
Carotenoid-rich fractions (CRF) from pulp and peel of a new variety purple tomato were investigated in comparison to Red Cherry regarding carotenoids characterization, antioxidant capacity, inhibition proliferation four tumor cell lines. CRF Purple contains lutein, lycopene, β-carotene up 6, 1.5, 2.5 times more than that it exhibited the highest activity at 400 μg/mL, reaching 82% 97% DPPH ABTS•+ assays, respectively. Besides that, showed scavenging lipoperoxides capacity as well displayed...
Co-encapsulation addresses the protection of multiple compounds from harmful conditions. However, release entrapped bioactive and probiotics in gut is required to achieve their health benefits. This study focused on co-encapsulation guaraná extracts by complex coacervation using gelatin gum Arabic, evaluating encapsulated during vitro digestion. The antioxidant activity stimulatory effect probiotic populations were also investigated. Guaraná seed extract (GSE) showed more significant...
Atualmente, são produzidas milhões de toneladas resíduos provenientes do processamento agroindustrial. Muitos deles ricos em compostos bioativos sendo potenciais fontes naturais dessas substâncias. Assim, este trabalho teve como objetivo avaliar o teor fenólicos totais, a atividade antioxidante e composição fenólica três gerados por agroindústrias brasileiras: bagaço uva Isabel (BI) (Vitis labrusca), Verdejo (BV) vinifera) goiaba (BG) (Psidium guajava). Os resultados totais (mg GAE g-1)...
Guava pomace is an example of the processing waste generated after manufacturing process from juice industry that could be a source bioactives. Thus, present investigation was carried out in order to evaluate anti-inflammatory and antinociceptive potential determinate main phenolic compounds guava extract (GPE). The activity evaluated by carrageenan, dextran, serotonin, histamine-induced paw edema neutrophils migration peritoneal cavity models. Acetic acid-induced abdominal writhing formalin...
This study aimed to elucidate the effect of pink pepper extract and different types packaging on physicochemical characteristics, oxidative stability dynamic sensory profile chicken burger. Pink was incorporated into burgers, which were stored in aerobic vacuum for 7 days at 2 °C. A formulation with synthetic antioxidant (butylated hydroxytoluene - BHT) a control (without antioxidants) also analysed. as effective BHT delay lipid oxidation burger after refrigeration. Vacuum preventing...
Abstract BACKGROUND Cocoa exhibits high content of phenolic compounds, among which trans ‐resveratrol stands out, associated with several bioactive activities such as antioxidant properties. Chocolate contains reduced amounts these compounds due to losses during the production process. Therefore, this study aimed assess changes in total content, and specifically ‐resveratrol, well activity cocoa its products industrial chocolate. RESULTS A ten different were analyzed. The processes...
Açaí seeds (Euterpe oleracea Mart.) are the major residue generated during industrial extraction of açaí fruit pulp - a popular and typical Amazon rich in bioactive compounds nutrients. In this study, we investigated bioaccessibility an seed extract using vitro simulated gastrointestinal digestion model. Catechin, epicatechin procyanidins B1 B2 were identified quantified monitored by HPLC-DAD through phases. Bioaccessibility these flavan-3-ols deactivation reactive oxygen species decreased...
ABSTRACT: The objective of this study was to determine and correlate the extraction yields, antioxidant activity, total phenolics flavonoids from grape, mango peanut agro-industrial by-products. β-carotene/linoleic acid autoxidation system scavenging capacity for DPPH ABTS free radicals assays were used. results expressed in terms lyophilized sample or dry extract. Mango bagasse exhibited highest yield (37.07%) followed by skin (15.17%) grape marc (7.92%). In sample, did not vary...
<p>Ready-to eat foods meet the demands of a modern lifestyle and number people seeking food that is convenient safe increasing. The extracts peels from four different fruits were tested as potential value-added to offer consumers. Physical chemical analyses peel conducted measure total phenolic compounds, tannins, phytic acid antioxidant activity using 1’-1’Diphenyl-2’picrylhydrazyl, 2,2’-azino-bis-3-ethylbenzothiazoline-6-sulphonic methods. result screening showed pomegranate had...
This study investigated consumers' perceptions of adding bee pollen to bread. An attitude questionnaire composed 48 statements related "general health," "light products," "natural "salty "food as a reward," "pleasure," and neophobia" was answered by the participants, who indicated their level agreement with each statement according 5-point Likert scale, ranging from (1) "totally disagree" (5) agree." A check-all-that-apply (CATA) also employed characterize 12 visual stimuli. The creation...
Abstract Background The use of antioxidants in applications for topical seems promising, however, many studies must be performed to ensure processes and products that can effectively bring benefits combat the action free radicals skin. For effective against from skin, it is essential compounds permeate different skin layers, reach deeper layers epidermis active form stay there a sufficient time cause beneficial effects. Aim This work aimed evaluate antioxidant formulations with phenolic as...
Brewers&rsquo; spent grain (BSG) is the major by-product of beer production (70-80% moisture) and feasibility its application in foodstuffs depends primarily on drying. Our objective was to evaluate effect physical separation with or without ultrasound color, total phenolic content (TPC), antioxidant activity, proximate composition, dietary fibers, particles size distribution BSG powders. From wet (W), two processes, (A) (B) ultrasound, encompassing pressing, convective air-drying,...
