Summary The objective of this study was to evaluate the influence whey protein isolate ( WPI ) and inulin blends on properties rosemary essential oil microencapsulated by spray drying. following ratios (w/w) were evaluated: 1:1, 1:3 3:1. Increasing concentration increased particle instantanisation times decreased moisture content. samples did not differ significantly P > 0.05) in hygroscopicity porosity. microcapsules produced at higher showed highest bulk density tapped different from...
Isomaltulose, known as Palatinose, is a low-glycemic carbohydrate commonly used in prolonged sports activities. In the present work, isomaltulose was incorporated mango slices by standard osmotic dehydration (OD) and pulsed vacuum OD (PVOD) at 45°C. Vacuum applied during first 10 min of PVOD. Both fresh osmotically treated samples were convectively dried (60°C, 1.5 m/s). The osmodehydrated products evaluated concerning hygroscopic behavior, color parameters, volumetric shrinkage, ascorbic...
ABSTRACT Osmotic dehydration (OD) process, as a pretreatment for drying, can be used to enrich mangoes with solute of interest and improve the nutritional sensory values this dried fruit. The research aimed obtain enriched isomaltulose. incorporation isomaltulose in mango ( Tommy Atkins ) slices was performed by ultrasound‐assisted osmotic (UAOD). Then, treated convectively (60°C 1.5 m/s). at 20 min maximum (≈ 5% solids gain) did not differ from experiments longer time. Firmness, color,...
Pitaya is a perishable fruit with high content of bioactive compounds. This study aimed to evaluate the influence ethanol pretreatment (95% dripped on surface foam at rate 0.05 mL.cm−2) and temperature (50 70 °C) moisture content, water activity, solubility, color, ascorbic acid, antioxidant capacity (DPPH FRAP) e betanin betaxanthin retention white red pitaya powdered pulps determine an optimal process condition. Pretreatment higher resulted in increased solubility pulps. The total color...
The aim of this study was to include prebiotic biopolymers as wall material in microparticles lime essential oil. Whey protein isolate (WPI), inulin (IN), and oligofructose (OL) were used the following combinations: WPI, WPI/IN (4:1), WPI/OL (4:1). emulsion droplets presence showed larger sizes on reconstitution. There no significant difference solubility particles, but wettability improved addition polysaccharides. size chains favored adsorption water. Prebiotic reduced thermal chemical...
Abstract Lignin is a source of phenolic compounds. It can be an excellent raw material for the production films with whey protein isolate (WPI). The present study investigates WPI lignin microparticles (LMP). structural, morphological, physical (thermal and mechanical analysis, water vapor barrier, color parameters, transparency) properties, antioxidant properties were determined. concentration LMP 0, 0.25, 0.50, 0.75% (w/w). Structural analysis showed addition to WPI‐based did not change...
The use of extracts rich in bioactive compounds is becoming increasingly common the food, cosmetics, and pharmaceutical industries for production functional products. Araticum a potential fruit to be analyzed due its content phenolic compounds, carotenoids vitamins, with antioxidant properties. Therefore, this study aimed investigate effect ultrasound on total carotenoids, ascorbic acid, color, turbidity rheology araticum juice. Response surface methodology based central composite design was...
The encapsulation capacity and the polymer blends containing gum Arabic (GA), inulin (IN), cellulose nanofibrils ginger (CNFG), extracted from fibrous residues, for microencapsulation of essential oil by spray-drying technique were evaluated in this study. addition CNFG improved emulsifying properties formulations, with an increase Newtonian viscosity (μ); however, partial substitution GA IN decreased viscosity. higher levels increased emulsion droplets formulations without CNFG. In...
This research presents an active biodegradable packaging, where papain was incorporated into chitosan films reinforced with cellulose nanofibers (CNF). The objective of this study to evaluate the properties chitosan-film and CNF (0%, 4%, 8%, w/w) 2%, 6%, 10%, their release in aqueous medium. Films were characterized by thickness, scanning electron microscopy, UV-Vis light transmission, X-ray diffraction, proteolytic activity, kinetics release. impaired dispersion polymer matrix increase...
Abstract This study aimed to evaluate the antioxidant activity of whey protein isolate (WPI) films containing different lignin microparticle (LMP) concentrations (0, 0.25, 0.50 and 0.75% w/w) during 4 days storage at 4°C. The was determined, effect active on prevention oxidation in ground meat ( Biceps femoris ) investigated by identification volatile compounds through gas chromatography coupled a mass spectrometer (GC–MS), thiobarbituric acid reactive substance (TBARS) values, myoglobin...
Neste trabalho, lodo de estações tratamento água foi incorporado a argila para produção tijolos cerâmicos com elevado desempenho quanto propriedades mecânicas. O resíduo possui potencial reúso devido à semelhança mineralógica argila. As técnicas difração raios-X no pó e espectroscopia vibracional na região do infravermelho transformada Fourier revelaram que os principais constituintes da são principalmente relacionados aos minerais quartzo, caulinita, gibsita muscovita. A análise...
