Applicability of an in vitro gastrointestinal digestion method to evaluation of toxic elements bioaccessibility from algae for human consumption.

This study aimed to investigate the bioaccessibility of toxic elements, including aluminum (Al), arsenic (As), nickel (Ni), cadmium (Cd), and lead (Pb) in five commercial algae consumed by humans in Italy. The degree of bioaccessibility of these elements may have important implications for human health. Simulation of gastrointestinal tract (GIT) digestion was divided into three stages through use of synthetic saliva, gastric, and bile-pancreas solutions.

Application of an in vitro digestion model for Po bioaccessibility assessment in seafood.

This study aims to investigate the bioaccessibility of Po in seafood and the impact of food preparation on this radionuclide. Polonium bioaccessibility is the fraction of Po mobilised from food matrices into digestive extractants when applying an in vitro digestion model. The degree of bioaccessibility of Po in food has important implications for estimating ingestion doses from this radionuclide.

Polonium bioaccessibility assessment in algae for human consumption: An in vitro gastrointestinal digestion method.

The occurrence and mobility of natural radioactive element as Polonium (Po) in 13 commercial algae consumed in Italy by humans were determined because the effects on human health need to take into account the bioavailability of these elements. The simulation of gastrointestinal (GIT) digestion was divided into three stages and was accomplished using three different artificial solutions: saliva, gastric, and synthetic bile-pancreas solution. The same sample was treated in two different ways: a) only gastric digestion and b) complete GIT digestion (gastric digestion followed by bile-pancreas solution).
