The effect of the concentrations polysaccharide from Anacardium occidentale L. (Policaju) and a surfactant (Tween 80) on relevant properties edible coatings/films, in view their application apples (cv. Golden) was evaluated. influence interactions between those two constituents apples' surface coating/film's wettability, water vapor permeability, opacity mechanical effects studied variables (polysaccharide concentrations) were analyzed according to 22 factorial design. Pareto bar charts used...
The encapsulation of curcumin into lecithin/chitosan nanoparticles (NPC) using the electrostatic self-assembly technique was evaluated. NPC were characterized through average size, zeta potential, polydispersity index (PDI), morphology (TEM), efficiency, Fourier Transform Infrared Spectroscopy (FT-IR), and thermal analyzes (TGA DSC). bioactive properties determined by antioxidant (DPPH) antimicrobial activities (against bacteria fungi); cytotoxic activity performed MTT assay against normal...
O processo de soldagem pulsada Hyper Dip-Pulse, encontrado nas fontes solda do modelo Tawers da Panasonic, destaca-se por sua capacidade controlar a transferência material fundido e forma arco. Para aprimorar eficiência aumentar velocidade soldagem, este trabalho visou personalizar curva corrente com o propósito reduzir os tempos ciclo produção e, consequentemente, produtividade linhas montagem que envolvem soldagem. consistiu em estudar algumas variáveis influenciam na poça fusão cordão...
WGA, an agglutinin from wheat germ which is largely responsible for many of wheat's allergies, was used as a model to investigate the action ionising radiation on WGA's anti-nutritive effects in sensitised mice. Based molecular structure, present study also examined structural modification WGA relation range dose. Structural integrity monitored using HPLC, fluorescence spectrometry and circular dichroism. Results showed loss intrinsic activity formation insoluble amorphous aggregates with...
Biobased polyurethane pressure-sensitive adhesives were produced with polyols based on epoxidized soybean oil (ESO) and isosorbide (ISO). Soybean oil-based polyol was synthesized via epoxide ring-opening ISO catalyzed by adding aluminum triflate (Al(OTf)3)─named ESOISO. Two recipes mixing the ESOISO polylactic acid (PLA) then reacting hexamethylene diisocyanate (HDI)─named PU ESOISO/PLA. The characteristic molecular groups of polyurethanes evidenced using FTIR NMR techniques (13C 1H NMR,...
The production of edible film from onion (Allium cepa L.) to be applied as packaging is attractive, due its chemical properties and biodegradable characteristics. Thus, we tested the hypothesis that can positively influence sensory properties, quality increasing shelf life beef burgers patties. experiment was designed in a 4 × 2 factorial scheme, with two treatments (beef patties or without film) at an interval four storage times (0, 3, 6 9 days) °C. uncoated burger (control) suffered most...
Antioxidants present in many fruit residues can play an essential role the prevention of diseases. The aim this study was to determine nutritional and mineral composition, fatty acids profile, anti-nutrients, bioactive compounds, antioxidant activity technological properties flour from generated by umbu processing. Nutritional composition showed high levels dietary fiber, especially insoluble fiber (56.67%). be classified as a good source calcium, phosphorus magnesium, excellent iron, zinc...
Few chronic food protein models have described the relationship between allergenicity and molecular structure of after physical processing. The effect γ-radiation on was measured by fluorescence, circular dichroism microcalorimetry. BALB/c mice were intraperitoneally sensitized then given non-irradiated irradiated Con-A daily gavage for 28days. tendency to form insoluble amorphous aggregates partially unfolded species observed irradiation. administration samples at low-dose significantly...
For medical biomaterials, xyloglucan dispersions can form films or gels to be applied as a wound dressing. this purpose, the structural characterization of dressing (XG) and containing 0.5 mg/mL concanavalin A (XGL) was performed. The lectin release capacity stability, cytotoxicity, pro-wound healing effects were also investigated. XG XGL prepared by mixing % (w/v) with 0.3 (v/v) glycerol. ConA incorporated in maintained its biological activity for fourteen days controlled-release manner....
The objective of this work was to obtain and characterize sodium alginate-based biopolymer films with the addition cashew nut shell liquid (CNSL). study employed a completely randomized design, including 0%, 0.5%, 1%, 1.5% inclusion CNSL. Uniform formation observed, CNSL provided better thermal resistance than did treatment without inclusion, while reduced homogeneity microstructure, especially for level. permeability film increased as level increased, in response concentrations 1% 1.5%, no...
A novel sanitizer tablet containing clove essential oil (CO) microemulsion was developed. preformulation study using nuclear magnetic resonance and thermal analyses showed component compatibility. The main components of the samples remained intact despite a color change, probably due to strong acid-base interaction between eugenol diethanolamine. CO acaricidal larvicidal activities superior commercial product, with product efficacy 99.9% larvae mortality 94%. Optimal spray-drying conditions...
The objective of this work was to develop a new edible coating based on the ethanolic residue Ziziphus joazeiro fruit pulp (POLIJUA) and evaluate its application in Coalho cheese, fresh cheese type. Films were developed using different concentrations glycerol best formulation applied cheeses their physical-chemical microbiological characteristics during 21 days storage. POLIJUA significantly decreased (p<0.05) weight loss samples when compared uncoated ones. It also able slow down lipid...
