Food antioxidants are a core topic of food science due mainly to the consumption ultra-processed foods, which cannot be overlooked, and represent an importance modern society. At same time, natural gaining attention in studies its safety aspects, that commonly affect choices. Based on this, present study aimed explore cognitive evaluation by consumers using qualitative consumer technique Word Association. Two stimuli were given. Respondents first asked write down four words came mind;...
The extraction process of bioactive compounds from propolis produced by selected bees was optimized using a 2³ factorial design planning to evaluate the effect ethanol concentration, time and temperature on total phenolic antioxidant activity.Analysis flavonoids, activity chemical characterization performed high-performance liquid chromatography with photodiode array (HPLC-PDA) detection were carried out in optimal conditions extraction.Optimizing results suggest that best condition for...
Glioblastoma, an aggressive intracranial tumor, presents significant therapeutic challenges due to the restrictive nature of blood–brain barrier (BBB), which limits effectiveness conventional treatments. This study aimed develop and optimize a nanoencapsulated system for intranasal delivery temozolomide (TMZ) perillyl alcohol (POH), designed circumvent BBB limitations, utilizing Eudragit RS100 as encapsulation matrix. A factorial design approach optimized key parameters, including...
Fruit juices are widely enjoyed beverages, valued for their organoleptic qualities, chemical composition, and nutritional benefits. They commonly sold as whole (WJs), reconstituted juices, or nectars, with WJs particularly favored by consumers seeking healthier, more balanced dietary options, often commanding a higher market value. However, these desirable characteristics make them vulnerable to fraud adulteration. To address this issue, novel strategy has been proposed classify into two...
Zein-based nanoparticles offer significant potential as carriers for drug delivery due to their biocompatibility. However, optimizing formulation is essential achieving efficient encapsulation and stability. This study aimed optimize the of zein-casein-hyaluronic acid-based a hydrophilic drug, focusing on favorable physicochemical properties oral applications. A factorial experimental design was employed evaluate influence key parameters, including zein concentration, hyaluronic acid sodium...
Cereal bars are foods that stand out for practicality in consumption and nutritional quality new formulations have been developed introduced to the market by large corporations. In present work, flours obtained from jabuticaba peel okara were employed as ingredients development of three cereal formulations. The products characterized physico-chemical parameters, microbiological sensory acceptance. showed high protein content (8.9 9.2 g 100-1 g) fiber (7.25 9.05 g), parameters according...
Abstract Commercial fruit flours were evaluated concerning: (i) the nutritional composition (proximate composition, total phenolic content, and minerals content), (ii) their contribution to estimated mineral daily intake, (iii) bioaccessibility of essential using in vitro INFOGEST digestion method (iv) influence chemical on bioaccessibility. The 20 samples analysed presented high variability concerning content dietary fibre (7.5 69.7 g/100 g), carbohydrates (4.1 74.9 protein (2.9 12.9 ash...
The aim of this study was to evaluate the most effective extraction condition (temperature, solvent type and time) for recovery high-value phytochemicals present in Tabernaemontana catharinensis leaves (TC) assess their effect on biochemical parameters streptozotocin-induced diabetic rats. phenolic compounds from TC using a factorial design (FD) 2³, high performance liquid chromatography (HPLC), response surface methodology (RSM) principal component analysis (PCA) were studied. It found that...
Abstract The objective of this research was to develop a model using Partial Least Squares‐Path modeling (PLS‐PM) explain the whole set relationships between Food Choice Questionnaire (FCQ) constructs interest in low sugar products being mediated by construct Health . results showed S ensory appeal as most important for consumers, followed Price and PLS‐PM revealed Weight control , Natural content Mood when having direct effect on importance given consumers foods sugar. This study also...
Agroindustrial waste in general presents significant levels of nutrients and organic matter has therefore been frequently put to agricultural use.In this context, the objective study was determine chemical composition, nitrogen, phosphorus, potassium, calcium, magnesium carbon content, as well qualitative characteristics through Fourier transform infrared spectroscopy four samples poultry litter one sample cattle manure, from southwestern region Paraná, Brazil.Results revealed that, general,...
The aim of the work was to study mechanical properties extruded starch/polyvinyl alcohol (PVA)/glycerol biodegradable blends using multivariate analysis. were produced as cylindrical strands by extrusion PVAs with different hydrolysis degrees and viscosities, at two temperature profiles (90/170/170/170/170 °C 90/170/200/200/200 °C) three conditioning relative humidities samples (33, 53, 75%). showed a great variability according PVA type, well profile humidity; tensile strength ranged from...
