Description
Summary:[Display omitted] •Baby food samples (puree, drink and petit Suisse): source of aluminium contaminant.•Possibility of determine Al concentration through an in vitro approach system.•The highest total Al content was found in handmade purees and petit Suisse samples.•Bioaccessibility levels reached up to 48 % depending on sample composition.•3 daily portions of soy-based drinks per week exceeded the Al TWI of 1 mg kg−1 bw. The objective of this study was to determine the total concentration and bioaccessible fraction of aluminium (Al) in 95 different baby food samples and estimate the exposure assessment. Total Al content was determined following oxidative microwave digestion by inductively coupled plasma optical emission spectrometry. An in vitro digestionmethod was optimized to evaluate the bioaccessible fraction. Total concentration and bioaccessibility varied according to the sample composition (saltypurees, fruit purees, infant drinks and petitsuisse). Petit suisse, soy-based drink and salty puree samples presented the highest total Al concentrations of 4170 μg kg−1, 2860 μg kg−1 and 2760 μg kg−1, respectively. Bioaccessiblefraction varied from 0.5%–48% according to their composition.Exposure to Al was estimated and compared with the tolerable weekly intakes currently established. The results showed that the consumption of 3 portions/day of soy-based drink along the week could represent a concern.
