This work aimed to provide a biochemical characterisation of Chlorella vulgaris biomass cultivated with daily supplementation produced water. The simultaneous phytoremediation and production biomolecules bioproducts commercial interest were analysed discussed. Cultures grown in laboratory scale photobioreactors for 26 days 1.5 L BG11 medium, 50 mL non-autoclaved water (TPW) or distilled (TDW). Biomass differed among the control (3.86 g L−1), TPW (1.69 TDW (1.82 L−1). TPW-treated culture...
This work aimed to use sodium trimetaphosphate/sodium tripolyphosphate cross-linked potato, banana, corn, cassava, and breadfruit starches as wall materials for C-phycocyanin encapsulation, characterize them evaluate their in vivo pharmacological effects an inflammation model. The were successfully obtained, characterized, submitted encapsulation by freeze-drying. characterization of starches-C-phycocyanin composites scanning electron microscopy, Fourier transform infrared spectroscopy,...
The use of non-dairy matrices for probiotic delivery can be beneficial vegetarian, vegan and lactose intolerant consumers. Stevia rebaudiana extract used as sweetener to replace sucrose glucose intolerants. This research evaluated the kefir grains prepare a low-calorie, fruit-based beverage. Fermentation was carried out by inoculating into mixture mango umbu pulps. Two beverages, one containing sucrose, other, stevia, were characterized according their proximate composition submitted 30-day...
Inadequate wastewater management can cause negative impacts on the ecosystem, becoming an obstacle to aquaculture growth. New technologies have been developed reduce nutrient load in involving microalgae as phytoremediation agents. In addition reducing of water bodies, microalgae-based also generate high-added value biomass. Arthrospira (Spirulina) is a little-explored genus agent for wastewater, representing about 30% biomass produced world that known its high concentration proteins,...
Abstract This work aimed to prepare and characterize cellulose nanocrystals as an additive a water‐based lubricating fluid. Different concentrations of the suspensions (0.50–1.25%wt) were added lubricant The nanolubricants submitted pin‐disk test. rigid/severe electrodynamic lubrication regime was conducted under different rotation speeds (500 63 rpm) external loads (8.47 1.77 N). showed high yield (74%), aspect ratio from 23 35, thermal stability at 219.0°C. coefficient friction increased...
This work aimed to evaluate the properties of butylene adipate-co-terephthalate (PBAT) degraded after 1800 days storage (DPBAT) by preparing blends (films) with crosslinked starch (Cm) through extrusion and thermocompression. Different ratios DPBAT:Cm (70:30, 60:40, 50:50 m/m) were prepared. The incorporation Cm into DPBAT significantly changed films making them stiffer (increasing Young's modulus up 50%) increasing thermal resistance DPBAT. presence in made less hydrophobic (with decreased...
Abstract Polymer blends can improve material processability and be used to extrude partially degraded materials, such as expired poly (butylene adipate‐co‐terephthalate) (PBAT), which cannot normally extruded. Therefore, in this study, the extrudability of PBAT that has passed its expiration date was restored by blending it with succinate) (PBS). Various polymer were extruded characterized achieve high‐efficiency extrusion. The carbonyl indices corresponding control sample detailed effects...
ABSTRACT Active packaging can be defined as that includes additives help to extend the shelf life of food; among advantages its use is possibility reduce amount added food during processing. The aim this study was develop, characterize, and apply active films low‐density polyethylene, incorporating carotenoid yerba mate extracts additives. were obtained by extrusion characterized for water vapor permeability, thickness, color, mechanical thermal properties. effectiveness evaluated using...
Abstract The present study aims to produce arrowroot flour fermented by kefir grains, in addition assessing the physicochemical, nutritional, and microbiological characteristics. Fermented was produced at room temperature (approximately 25 28 °C). Fermentation conducted batch (6 kg of substrate 10% grains were added with homogenization every 3 hr). Samples evaluated 12 hr for both fermentation processes (fermentation process 1: 24 2: 48 flours qualities, using a completely randomized design,...
Traditional methods to obtain nanocellulose crystals typically involve mechanical and chemical processes develop an improved process in terms of efficiency, sustainability, the quality CNCs produced are interesting. In this sense, we aimed prepare cellulose nanocrystals (CNCs) from hydrolysis microcrystalline using protic ionic liquids (PILs), named 3-diethylamino-propylammonium hexanoate ([DEAPA][Hex]), 3-dimethylamino- 1-propylammonium ([DMAPA][Hex]), propylammonium ([PA][Hex]) at...
Edible insects are a potential alternative food source of high feed conversion efficiency and protein content. Zophobas atratus is an edible insect that adapts to different diets, enabling sustainable rearing by adding value by-products agro-industrial residues. This study aimed evaluate the performance nutritional characterization larvae fed with proportions grape residue. Physicochemical analysis diets (AOAC procedures), fatty acid profile (chromatographic techniques), metals non-metals...
Stingless bees are endemic in northeastern Brazil, where they exploited for honey production and crop pollination. The therapeutic use of can be attributed to its antibacterial antioxidant activities. effects time storage temperature on Melipona scutellaris were evaluated by physicochemical microbiological parameters as well the analysis bioactive compounds activity. Fresh samples monitored at 5 30 °C 150 days. total acidity HMF increased, while pH diastase activity significantly decreased...
Abstract This study aimed to evaluate the effects of incorporation cowpea protein isolate and cassava starch nanoparticles obtained by ultrasound on properties starch:glycerol films. The bean was successfully with 72.5% solubility about 90%. yielded 97.85%. Increasing concentration in films resulted a progressive reduction water vapor permeability up 27.0%. added presented expressive increments tensile strength (283.83%) as well modulus elasticity (204.31%), accompanied decreasing elongation...
