Estimation of the Bioaccessibility of Metallic Elements in Chocolate Drink Powder using anin vitroDigestion Method and Spectrometric Techniques

Method Validation for Multi-Elemental Analysis of Dialyzable and Non-dialyzable Fractions of Coffee Brews by F AAS and ICP OES: a Bioaccessibility Study

“…In recent years, in vitro gastrointestinal digestion has been applied to estimate bioaccessibility of elements from various food products and beverages, including fruit juices (Cautela et al 2009;de Lima et al 2014;Haro-Vicente et al 2006), infant formulas (Bermejo et al 2002;do Nascimento da Silva et al 2017), tea (Powell et al 1998;Erdemir 2018), herbal infusions (Pereira Junior et al 2018;Zhou et al 2014), GCs and ICs (Stelmach et al 2014(Stelmach et al , 2016, slim coffees (Szymczycha-Madeja et al 2015), chocolate drink powder (Peixoto et al 2013), various milks (Bermejo et al 2002;Chaiwanon et al 2000;Shen et al 1995), honey (Pohl et al 2012), fruits and vegetables (do Nascimento da Silva et al 2015;Khouzam et al 2011;Machado et al 2017;Oliveira et al 2018;Pereira et al 2016), breads (Gawlik-Dziki et al 2009;Khouzam et al 2011;Lamsal and Beauchemin 2015), cereals (do Nascimento da Silva et al 2017), white cheeses (Khouzam et al 2011), various meats (Menezes et al 2018), and edible seaweeds (Dominguez-Gonzalez et al 2010;García-Sartal et al 2011. Commonly, a two-step procedure that simulates stomach and intestinal digestion with solutions of pepsin in the gastric phase and a mixture of pancreatin and bile salts in the intestinal phase is used.…”

Multivariate approach to assess in vitro Fe bioaccessibility in chicken meat

“…In Brazil, The Brazillian Health Regulatory Agency, ANVISA, based on the World Health Organization`s recommendations, established the daily intake of this element for various population groups: adults (14 mg Fe/day), pregnant (27 mg Fe/day) and lactating (15 mg Fe/day) women who require higher values (Brasil, 2005) Due to the critical role of iron in human nutrition, it is necessary to determine the total concentration in food as well as the quantity that is available for absorption in the gastrointestinal tract. This quantity is frequently denominated as the bioaccessible fraction (Peixoto et al, 2013). Most studies, however, involve the determination of total iron in food stuffs and cannot provide this important piece of nutritional information.…”

“…The bioaccessibility of an element can be realized by in vivo tests, using experimental animals or even humans, or in vitro experiments. Ethical concerns and higher costs have been a considerable limitation for in vivo studies (Peixoto et al, 2013). In such cases, many in vitro methods can be found in the literature to obtain bioaccessible and bioavailable fractions for metals from foodstuffs (Miller et al, 1981;Luten et al, 1996;Cámara et al, 2005;Purchas et al, 2006;Kulkarni et al, 2007;Hur et al, 2011;Ramos et al, 2012).…”

“…Studies with respect to the bioaccessibility of mineral elements in various types of food are plentiful in literature (Miller et al, 1981;Luten et al, 1996;Cámara et al, 2005;Purchas et al, 2006;Kulkarni et al, 2007;Hur et al, 2011;Maulvault et al, 2011;Koch et al, 2011;Ramos et al, 2012, Peixoto et al, 2013Stelmach et al, 2014;Silva et al, 2015;Pereira et al, 2016) but are particularly rare concerning chicken products. Despite the amount of in vitro bioaccessibility studies, there is one paper that suggests a consensus (Minekus et al, 2014) for this type of experiment to be applied to food matrices (foods in general).…”

“…Furthermore, very few works on this topic are found in the Brazilian literature (Nascimento et al, 2010;Peixoto et al, 2013;Silva et al, 2015;Pereira et al, 2016) In this sense, it is important the development of studies regarding the bioaccessible fractions of nutrients in food widely and routinely consumed in Brazil, such as chicken meat. Additionally, the contents of a mineral micronutrient such as iron can be influenced by several factors in meat such as the breed, age, sex and nourishment of the animal (Olivio, 2008).…”
