Honey is an excellent alternative to be used in different applications by the food, pharmaceutical, and cosmetics industries. However, use of honey its liquid form can present several disadvantages due high viscosity density. In addition, naturally crystallize during storage time, limiting application new products Thus, using industry powder form. The objective this study was obtain spray drying a plant-based protein as carrier. raw material showed acceptable physicochemical parameters...
In vitro gastrointestinal digestion of babassu mesocarp in the absence and presence milk lignin was performed to evaluate bioaccessibility Cu, Fe, Zn. Extractions using NaOH solutions (pH 7 12) were carried out interactions Cu(II), Fe(III), Zn(II) with extracted compounds washed mesocarp. Studies reference showed a decrease free concentration elements Phytate, component present mesocarp, can be main compound responsible for elements' Lignin increases soluble fractions; however,...
A method for the simultaneous determination of aluminum (Al), arsenic (As), calcium (Ca), cadmium (Cd), chromium (Cr), copper (Cu), iron (Fe), magnesium (Mg), manganese (Mn), phosphorus (P), lead (Pb), sulfur (S), selenium (Se), vanadium (V), and zinc (Zn) in organic soil amendments using microwave-assisted acid digestion inductively coupled plasma optical emission spectroscopy (ICP OES) is proposed. Concentrated or diluted acids mixtures (HNO3, HF, HBF4, H3BO3) combined not with H2O2 were...
A systematic approach is proposed to evaluate microwave-assisted digestion in a single reaction chamber for the simultaneous determination of elements mineral fertilizer and raw material by inductively coupled plasma optical emission spectrometry. reference was digested using 12 acid mixtures containing nitric, hydrochloric, orthophosphoric, hydrofluoric or boric acid. Principal components analysis applied data treatment. Three procedures based on diluted acids exhibited most accurate...
The sequential extraction procedure of the Community Bureau Reference (BCR) was applied to investigate mobility potentially toxic elements (As, Cd, Cr, and Pb) nutrients (P, Ca, Mg, Cu, Fe, Mn, Zn) in a multinutrient mineral fertilizer based on phosphate rocks supplemented with 10% (w w-1) micronutrient mixture (raw material used as source). For both samples, As Cd were more mobile, whereas Cr remained solid residue. A higher Pb observed mixture; however, high concentration P (8.3% w could...
The presence of bioaccessible potentially-toxic elements in five different brands temporary tattoos (packaged with bubble gums) aimed at children and three product used by young adult audiences were analyzed accordance the Brazilian Organization Technical Standards (ABNT) International for Standardization (ISO) toy’s safety standards. Bioaccessible barium, copper strontium found concentration range between 1.78–11.1 μg g–1, 0.0364–0.875 0.155–9.9 respectively. lead (2.6 ± 0.1 g–1 – 4.36 0.06...
