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;...
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...
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...
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...
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 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...
Moringa oleifera leaves are cultivated in warm regions of Brazil for commercial ends due to their nutritional and biological properties. This study evaluated, by chemometric tools, the influence seasonality (winter, spring, autumn, summer), growing area (South, Southeast, Northeast), regrowth age (40 80 days) antioxidant potential, biochemical markers determined HPLC-DAD. The results obtained present showed that all parameters evaluated were affected seasonality, age, region. content...
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...
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...
The use of fast and low-cost methods to optimize the total phenolic compounds (TPC) extraction has been gaining attention in ethnopharmacological research. Extraction conditions bioactive from Calycophyllum spruceanum barks were established through multivariate regression models. In this sense, fractional factorial design (FFD) central rotational composite (CCRD) developed using partial least squares (PLSR) combined with information color images spectrophotometry tools evaluate antioxidant...
