Fast method to determine the elements in maize flour: reduction in preparation time and reagent consumption

Abstract: The aim of this work was to develop and validate methodology to reduce the digestion time and reagent consumption in the determination of minerals in maize flour. The standard methodology employed in Brazil is that described by AOAC. It consists of the calcination of the sample at high temperatures for a long period of time, making the process expensive and slow. In this work, a wet sample digestion method using HNO 3 was employed, heating on a block digester with final dissolution in an ultrasonic bath. The v… Show more

“…The flours were submitted to an analysis to evaluate the granulometry according to methodology of Kelte-Filho et al [18]. In this procedure, a fraction of 100g is used, placed in a system of overlapping sieves (30,35 and 50 mesh, respectively 600, 500 and 300 μm, according to [17] and these are subjected to agitation by time around 3 minutes, to check the amount of material retained in each sieve.…”

“…Desta forma, substituíram-se as tampas plásticas dos tubos de ensaio por ponteiras de micropipetas durante o processo de digestão das amostras (ensaios 9 e 10) como apresentado em artigo publicado anteriormente. 24 As ponteiras (diâmetro de 1,0 cm) se encaixaram perfeitamente na boca do tubo de vidro e seu pequeno orifício na ponta permitiu a saída de vapor ácido durante a digestão. Nos ensaios 9 e 10, variou-se a massa da amostra de testículo bovino de 0,3 g para 0,5 g para verificar se o procedimento era viável com massas maiores e eliminou-se a introdução de H2O2 do meio de digestão.…”

“…The granulometric analysis of the flours (PFAh and SFAh) was determined according to Kelte-Filho et al (2017) with adaptations, using a set of sieves with metallic meshes (32, 48, 60, 85 and 100mesh) coupled to an electromagnetic sieve shaker (model#00015 -110V). The sieves were weighed empty and overlapped according to the opening of their meshes, in descending order.…”
