“…ICP-OES/AES was mostly used to determine the geographical origin of honey [ 48 ], wines [ 49 ], cumin [ 45 ], vinegar [ 50 ], coffee beans [ 46 ], baby foods, vegetables, milk powder [ 47 ] for minerals such as Mn, Zn, P, Fe, Cu, Rb, Mo, Ba, Sr and Ni. Slurry sampling had also been applied for the determination of minerals in sugarcane with ICP-OES [ 43 ]. Soft drinks were successfully analysed for several elements [ 44 ] ( Table 2 ).…”

Food composition database (FCD) provides the nutritional composition of foods. Reliable and up-to date FCD is important in many aspects of nutrition, dietetics, health, food science, biodiversity, plant breeding, food industry, trade and food regulation. FCD has been used extensively in nutrition labelling, nutritional analysis, research, regulation, national food and nutrition policy. The choice of method for the analysis of samples for FCD often depends on detection capability, along with ease of use, speed of analysis and low cost. Sample preparation is the most critical stage in analytical method development. Samples can be prepared using numerous techniques; however it should be applicable for a wide range of analytes and sample matrices. There are quite a number of significant improvements on sample preparation techniques in various food matrices for specific analytes highlighted in the literatures. Improvements on the technology used for the analysis of samples by specific instrumentation could provide an alternative to the analyst to choose for their laboratory requirement. This review provides the reader with an overview of recent techniques that can be used for sample preparation and instrumentation for food analysis which can provide wide options to the analysts in providing data to their FCD.

“…13,14 As vantagens da amostragem em suspensão frente aos métodos convencionais de preparo de amostra incluem a simplicidade, rapidez, menor risco de contaminação da amostra e perdas do analito e redução do volume de reagentes tóxicos. [15][16][17] A técnica de espectrometria de absorção atômica em forno de grafite (GF AAS) é uma das mais utilizadas para a determinação de elementos traço em diversos tipos de amostras por apresentar elevada seletividade e sensibilidade. 8 Além disso, esta técnica permite a realização de análises com o mínimo preparo de amostras devido à existência de uma etapa de pirólise no programa de aquecimento, a qual auxilia na remoção da matriz orgânica da amostra.…”

“…14 A amostragem em suspensão tem sido amplamente utilizada no preparo de diferentes tipos de amostra para a determinação de minerais, especialmente associada às técnicas de espectrometria de absorção atômica. [14][15][16][17][18] Andolfatto 19 utilizou a técnica de amostragem em suspensão para a determinação de Mn, Zn, Fe e Mg em melado de cana por FAAS, sendo que o método otimizado apresentou precisão e exatidão adequadas. Entretanto, a aplicação dessa técnica para a determinação de minerais em melado de cana ainda é escassa.…”

In this work, a slurry sampling method was used for chromium determination in cane syrup by GF AAS for the first time. The cane syrup slurries were prepared by dissolution of the samples with ultrapure water. Method validation was carried out by evaluating parameters such as linearity, detection and quantification limits, precision and accuracy. The analytical curve was prepared by external standardization and low values of detection and quantification limits were found (7.2 and 22.0 ng g-1 , respectively). The repeatability and intermediate precision estimates demonstrated that the method presents an adequate precision (RSD < 20%). The accuracy assessed by the recovery rates (102-113%) and the comparison with the reference method (p = 0.562) was also adequate. The validated method was applied to twenty cane syrup samples from different Brazilian states, whose chromium concentrations ranged from 29.8 to 254.1 ng g-1. Neste trabalho, um método de amostragem em suspensão foi utilizado para a determinação de cromo em melado de cana por GF AAS de forma inédita. As suspensões de melado foram preparadas pela dissolução das amostras com água ultrapura. A validação do método foi realizada pela avaliação de parâmetros como linearidade, limites de detecção e de quantificação, precisão e exatidão. A curva analítica foi preparada por padronização externa e baixos valores de limites de detecção e de quantificação foram encontrados (7,2 e 22,0 ng g-1 , respectivamente). As estimativas de repetitividade e de precisão intermediária demonstraram que o método apresenta uma precisão adequada (RSD < 20%). A exatidão avaliada por meio das taxas de recuperação (102-113%) e da comparação com método de referência (p = 0,562) também foi adequada. O método validado foi aplicado a 20 amostras de melado de cana de diferentes estados brasileiros, cujas concentrações de cromo variaram de 29,8 a 254,1 ng g-1 .
