In recent decades, direct solid sample analysis has been reported in the literature as an alternative to traditional methods of preparation, becoming well established atomic spectrometry field.
Surimi is a concentrate of myofibrillar proteins obtained from solid residues fish processing, which minced, washed, drained and final by the use stabilizing agents. The aim this study was to evaluate influence using different species: whitemouth croaker (Argyrosomus regius), snapper (Lutjanus purpureus), sandperch (Pseudopercis Numida) tilapia (Oreochromis niloticus). surimi preparation method included immersion in an alkaline solution, followed two immersions saline solutions, water...
The present study aims to develop a fast and simple method for the determination of potassium (K), magnesium (Mg) phosphor (P) in bean seed samples employing data fusion strategy low-level with laser-induced breakdown spectroscopy (LIBS) wavelength dispersive X-ray fluorescence (WDXRF) techniques combined direct solid sample analysis. Univariate multivariate (multiple linear regression, MLR) calibration leave-one-out cross validation strategies were evaluated build models correlated...
Two fast, simple and reliable methods for the determination of Cu Mn in infant formula were developed by HR-CS GF AAS.
POTENTIALITIES.This review attempts to present a broad view of the technique laser-induced breakdown spectroscopy (LIBS), since its origin, fundamentals, sample preparation strategies, use chemometric tools for data processing, advantages and limitations with regard qualitative quantitative analysis, aplications future trends as an analytical that is in consolidation chemistry.LIBS rapid versatile, which able providing information practically any sample, virtually non-destructive way,...
In this review, quality by design (QbD) initiatives are described as applications for many types of processes, such in the pharmaceutical industry, biotechnology field, and analytical methods development. Design space (DS) experiments (DoE) provide useful results development simulation advanced processes traditional manufacturing relationships. The three topics, QbD, DS DoE best way to achieve strong efficient industrial production.
Hyperspectral images obtained using LIBS for edible seeds evaluation of chemical profile.
The aim of this study was to evaluate solid calibration standards for matrix-matching comparing with multivariate strategies calcium and magnesium determination in bean seed samples employing laser-induced breakdown spectroscopy combined direct analysis. Four strategies, namely, (i) partial least square (PLS), (ii) principal component regression (PCR), (iii) multi-energy (MEC) (iv) one-point gravimetric standard addition (OP GSA), were assessed fourteen samples. From all used study,...
As indústrias alimentares, em virtude de seus processos produtivos, podem gerar efluentes que quando descartados sem o devido tratamento contaminar corpos receptores. Este pressuposto leva a necessidade estudar tecnologias, visando minimização dos possíveis impactos ambientais. A presente pesquisa tem como objectivo, avaliar tratabilidade da indústria óleo coco por meio adsorção, utilizando fibra material bioadsorvente. Trata-se um estudo aplicado, baseado no método experimental escala...
Liqueur is a spirit drink resulting from mixture of ethyl alcohol agricultural origin and/or brandy, drinking water, sugar and possibly other foodstuffs, with sweet taste flavored by maceration vegetable substances or distillation the same addition flavorings. The aim this study was to assess physicochemical sensory quality combined orange-fleshed potato lemon balm liqueur. Four formulations were produced: (A) 30% 15% 2% balm; (B) 35 % 10% 1.5 (C) 45% 5% 1% (D) 47% without all which...
This study presents a microwave-assisted procedure for sample preparation of cocoa beans using diluted HNO 3 with H 2 O the determination Ba, Ca, Cu, K, Mg, Mn, P, S, Sr and Zn by inductively coupled plasma optical emission spectrometry (ICP OES).Doehlert modified design was used optimization experimental condition, volume (0, 0.5, 1.75 mL) concentration (0.5, 3.75 7 mol L -1 ) were evaluated.The best conditions chosen considering lower residual acidity (RA), dissolved organic carbon (DOC)...
