This study evaluated the antimicrobial activity (i.e., against Bacillus cereus and Staphylococcus aureus) antioxidant ABTS, FRAP, DPPH) of annatto seeds extract obtained by ultrasound-assisted extraction. A response surface design with three levels such as pH (2-11), solvent concentration (50-96 %), seed-to-solvent ratio (1:2-1:10), treatment time (0-30 min) was employed to determine optimal experimental conditions. Thus, a 7.0, 1:7, 20 min were selected rendering an having 0.62% bixin, 3.81...
Abstract The aim of this work was to determine (1) the total phenolic compound ( TPC ), flavonoid TFC ) and bixin norbixin content polar extracts leaves ALE seed ASE from annatto B ixa orellana L .); (2) antioxidant activity, by means different tests, (3) effectiveness on growth inhibition several bacterial strains. Five test systems were used while microdilution method for antimicrobial activity. presented higher P < 0.05) than . As regards at all concentrations tested with methods,...
Abstract To compare the encapsulation of annatto extract by external gelation (EG) and internal (IG) to maximize process yield (% Y), two central composite designs were proposed. Calcium chloride (CaCl 2 ) concentration (0.3–3.5%), alginate gelling solution ratio (1:2–1:6); acetic acid (CH 3 COOH) (0.2–5.0%) (1:2–1:6) taken as independent variables for EG IG respectively. Release studies conducted under different conditions; morphology, particle size, efficiency (EE), release mechanism...
Metabolic syndrome (MetS) is characterized by increased oxidative stress and a pro-inflammatory state. Vaccinium meridionale Swartz (known as “agraz”) berry rich in polyphenolic compounds with demonstrated antioxidant activity anti-inflammatory effects preclinical studies. The aim of this study was to evaluate the agraz consumption on inflammatory markers women MetS. Forty MetS (47 ± 9 years) were randomly assigned consume daily either 200 mL nectar or placebo over four weeks double-blind,...
Metabolic syndrome (MetS) is associated with low-grade inflammation and high-density lipoprotein (HDL) dysfunction. Polyphenol-rich foods may improve these alterations. Agraz a fruit rich in polyphenols (mainly anthocyanins); however, there limited information about its effects on human health. We evaluated the of agraz consumption as compared to placebo HDL function women MetS. Forty volunteers (25–60 years) were included this double-blind crossover study. Women consumed or over 4 weeks;...
Two novel ingredients were incorporated into spreadable liver pâtés to study their effect on physicochemical and sensory characteristics possible use in the meat industry. Fresh date (Phoenix dactylifera, cv. Confitera) co-products, as a paste (0, 2.5 7.5%), annatto (Bixa orellana) extract (0 128 mg/kg), colourant, combinations final quality. The six formulations analysed for chemical composition, (pH, aw, colour, emulsion stability, texture), properties. Pâtés tolerated suitable...
The consumption of antioxidants can prevent chronic non-communicable diseases and the exotic Colombian fruits, goldenberry (Physalis peruviana L.) purple passion fruit (Passiflora edulis f. Edulis Sims), are rich in bioactive compounds. aim this work was to characterize optimize antioxidant activity these fruits blend. were classified according their maturity stages, freeze-dried extracts physiochemically characterized, polyphenols, carotenoids quantified, an experimental mixture design...
Colombian berry (agraz) has demonstrated a high antioxidant content in vitro. In the present study, it was elaborated and characterized an agraz nectar, designed placebo with similar physicochemical sensorial characteristics of but without polyphenols; evaluated their capacity both vitro vivo adults cardiovascular risk factors. The polyphenolic concentration nectar its superior than other reported for this fruit. A total cyanidins observed freeze-dried agraz, not delphinin detected by HPLC....
The objective of this study was to optimize mass transfer during pulsed vacuum osmotic dehydration (PVOD) cape gooseberries (Physalis peruviana L.) by means the surface response methodology. effects factors temperature (25-45°C), solids (50-70°Brix), rotation speed (60-100 rpm), pressure (50-100 mbar) and number pulses (1-3) on dehydration, weight reduction percentage (WR), water loss (WL), solid gain (SG%) were assessed. Sucrose syrup at a 5/1 syrup/fruit ratio used for 2 h. results...
Abstract Dates are an interesting source of bioactive compounds, and coproducts from the date industry potential use in manufacturing meat products. In present research, spreadable pork liver pâtés were made using fresh (2.5% 7.5%) as a functional ingredient ethanolic annatto extract (128 mg/kg) colorant. The effect these 2 ingredients on lipid oxidation microbial quality was assessed during 21 d storage. containing 7.5% paste seen to have highest content phenolic compounds combination 2.5%...
Goldenberry and purple passion fruit contain bioactive compounds (BCs) that can prevent gastrointestinal cancers; hydrogel beads protect control their release in the tract. This study aimed to develop an encapsulating material for (FHBs) increase bioaccessibility assess antiproliferative effects. A blend of goldenberry-purple was encapsulated using ionic gelation electrospraying. Through a mixture experimental design with sodium alginate (SA), hydroxypropylmethylcellulose (HPMC) arabic gum...
