A sequential strategy was proposed to detect adulterants in milk using a mid-infrared spectroscopy and soft independent modelling of class analogy technique. Models were set with low target levels adulterations including formaldehyde (0.074g.L-1), hydrogen peroxide (21.0g.L-1), bicarbonate (4.0g.L-1), carbonate chloride (5.0g.L-1), citrate (6.5g.L-1), hydroxide hypochlorite (0.2g.L-1), starch sucrose (5.4g.L-1) water (150g.L-1). In the first step, one-class model developed unadulterated...
There is no any doubt about the importance of food fraud control, as it has implications in safety and consumer health. Focusing on fruit beverages, some types adulterations have been detected more frequently, such substitution with less expensive fruits. A methodology based attenuated total reflectance Fourier-transform mid-infrared spectroscopy (ATR-FTIR) multivariate classification was applied to detect whether grape nectars were adulterated by apple juice or cashew juice. 126 samples...
The consumption of vegetarian/vegan products that mimic the taste and appearance animal has grown worldwide. objective this study was to investigate designations these in Brazilian market, focusing on terms may mislead consumers. were evaluated concerning four aspects: i) use "vegan,' "vegetarian,' or similar ones; ii) misuse standardized product designations; iii) misspelling iv) term "type" "flavor" associated name products. There 335 samples analyzed, 93 from supermarkets 242 websites,...
A green screening method to determine cashew nut adulteration with Brazilian nut, pecan macadamia and peanut was proposed. The based on the development of a one-class soft independent modelling class analogy (SIMCA) model for non-adulterated nuts using near-infrared (NIR) spectra obtained portable equipment. Once is established, assignment unknown samples depends threshold established authentic class, which key aspect in any approach. authors propose innovatively define two thresholds: lower...
Um procedimento detalhado para validação intralaboratorial de métodos, incluindo delineamento experimental, estatísticas e avaliação premissas foi proposto aplicado à um método ensaio avermectinas em leite bovino por cromatografia líquida alta eficiência com detector fluorescência. Foram realizados ensaios curvas solventes matriz, amostras brancas adicionadas. As relacionadas às empregadas foram avaliadas confirmadas. Linearidade obtida entre 25 150 ng.mL-1. Não observados efeitos matriz...
