“…The bioaccessibility assessment method and factors affecting the assessment results of food still need further investigation and validation to human absorption. According to existing results, food‐borne Ni bioavailability in the human gastrointestinal tract ranges between 1.7 and 10% (Babaahmadifooladi et al., 2020), and larger variations in bioavailability (low to 100%) have been found in baby food for Fe, Zn, Cu, and Mn (da Silva et al., 2013). Rice Cd bioaccessibility within the human gastrointestinal tract has also been shown to vary substantially (7.9–24%) (Tefera et al., 2020).…”

Wheat (Triticum aestivum L.) flour consumption may be a major source of human metal intake, especially when wheat is cultivated in metal-contaminated soils. This work investigated Cd, Cu, Pb, and Zn distribution in whole wheat flour, wheat flour, and wheat bran when grown in an area polluted by Pb smelting. Wheat product heavy metal concentrations were analyzed, and the (non)carcinogenic risks were assessed. Mean Cd, Cu, Pb, and Zn concentrations in whole wheat flour were 0.38, 3.83, 0.48, and 29.3 mg kg-1 , respectively; those in flour were only slightly reduced. The ratios between noncarcinogenic average daily dose of whole wheat flour and wheat flour consumption ranged from 1.06 to 3.76, with Pb having the greatest values compared with other metals. For children, the average hazard quotients (HQs) of whole wheat flour consumption of Cd, Cu, Pb, and Zn were 4.19, 1.06, 1.53, and 1.07; those for wheat flour consumption were 3.81, 0.68, 0.70, and 0.98, respectively. The HQs of adults were less than those of children. Overall results indicated that consumption of wheat products may lead to health concerns in the heavy metal contaminated area, yet when wheat flour rather than whole wheat flour is consumed, only the human health risk from Pb ingestion is reduced. Altering or removing human edible crops in the most contaminated areas should be considered.

“…Observe-se que, em geral, os métodos in vitro envolvem uma digestão gastrointestinal simulada com pepsina durante a etapa gástrica, seguida pela etapa intestinal com pancreatina e sais biliares para a determinação das frações solúvel e dialisada de Ca, Cu, Fe e Zn. Dos 20 estudos apresentados, envolvendo bioacessibilidade e/ou biodisponibilidade de minerais em FI, apenas dois descreveram uma etapa oral prévia à digestão gastrointestinal (Silva et al, 2013a;Gomez et al, 2016). As referências mais citadas entre os artigos encontrados foram os estudos de Miller et al (1981) e Luten et al (1996), com adaptações referentes ao volume de enzimas e sais biliares adicionados durante a digestão intestinal.…”

“…A determinação do teor total dos nutrientes presentes em FI é fundamental para garantir a qualidade do produto, segundo as legislações e normas (Brasil, 2011a). Todavia, conhecer a concentração total de nutrientes no alimento não é suficiente para determinar se o alimento provê as necessidades nutricionais adequadas, sendo importante o conhecimento da fração que pode estar efetivamente disponível para absorção pelo organismo (Silva et al, 2013a). Neste sentido, é importante o estudo da bioacessibilidade ou da biodisponibilidade dos nutrientes, de forma a avaliar sua potencial absorção pelo organismo (Minekus et al, 2014).…”

Resumo A fórmula infantil é a opção de alimento mais recomendada quando a amamentação não é possível. Para o melhor entendimento do comportamento gastrointestinal e da absorção dos nutrientes presentes nas fórmulas infantis, realizam-se estudos que simulam os processos de digestão. Este trabalho teve como objetivo discutir a evolução das fórmulas infantis com foco na avaliação da absorção de Ca, Cu, Fe, K, Mg, Mn, P e Zn, identificando métodos disponíveis para a avaliação de bioacessibilidade e de biodisponibilidade, de forma a melhor entender a absorção desses nutrientes. Para isto, foi realizada uma revisão bibliográfica sobre fórmulas infantis e os métodos in vitro mais utilizados no estudo de minerais, com foco no consumo, na qualidade e nos aspectos tecnológicos. Foi constatada uma tendência mundial no aumento do consumo de fórmulas infantis e verificou-se que estudos de biodisponibilidade e bioacessibilidade de minerais, mesmo que ainda escassos, colaboram para a evolução e o desenvolvimento deste produto, visando a uma aproximação com a composição do leite materno. A pesquisa mostrou que a composição da fórmula infantil vem sendo constantemente aperfeiçoada por revisões das legislações e pela indústria, e que, para a obtenção de uma fórmula infantil com alta capacidade de absorção de nutrientes, devem ser realizados estudos de bioacessibilidade e/ou de biodisponibilidade, pois estes estudos possibilitam uma melhor compreensão da influência dos diferentes ingredientes na absorção dos nutrientes. Os estudos também mostraram que, para uma ingestão mais equilibrada, nas diferentes fases do lactente, são necessárias diferentes composições dos nutrientes nas fórmulas infantis.

“…Thus, composition and consumption patterns of baby foods as well as right proportions of trace elements are highlighted in earlier works [2,3]. In this context, a variety of studies have been carried out on the levels of trace elements in baby foods by different analytical techniques [1][2][3]5,8,[11][12][13][14]. Although atomic absorption spectrometry, inductively coupled plasma optical emission (ICP-OES) and inductively coupled plasma mass spectrometry (ICP-MS) are leading examples of quantification of elements, ICP-MS come to the forefront as a multi elemental analytical technique for such analytes present in food at trace and ultra-trace levels that provides accurate and sensitive determinations [9,12].…”

“…Baby food is any food given to infants, with a soft or liquid texture from the age of 6 months to 2 years [7] and also assessed as complementary foods as they seem additional rather than mother's or formula milk [1]. They could be commercially found in markets within various forms such as instant milk flour, salty foods, purees made from fruits, vegetables or processed mixed products [7,8]. These ready-to-feed food forms are intended to use for consumption of infants and toddlers to include minerals and vitamins at sufficient levels [1].…”

In this study, total concentrations and bioaccessibility of some essential and toxic elements (As, Cd, Cr, Cu, Fe, Mg, Mn, Ni, Pb and Zn) were determined in commercial fruit purees intended for baby consumption as complementary foods. Enzymatic in vitro digestions were performed to simulate the stomach and the intestine conditions. A fivelevel, three factor central composite design, was applied to optimize the open-wet digestion methodology as well as enzyme amounts used in vitro methods to achieve maximum elemental levels. Rice flour and baby food composite certified reference materials analysis were applied to optimize the digestion parameters and evaluate the accuracy of the optimized method. Water fractions of samples were analyzed and evaluated in terms of their suitability for risk assessment studies by inductively coupled plasma mass spectrometry. Recommended dietary allowance level of 1.3% for Zn, adequate intake levels of 15.3%, 0.04%, 4.4% and 68% for Cu, Mg, Mn and Cr, respectively were achieved as well as 20%, 6% level and 2% tolerable intakes of Cd, Ni and As, respectively. Thus, contribution of the consumption of one jar of fruit based complementary baby food to diet of infants aged up to 12 months were assessed.
