Estimation of ethanol and methanol exposure through jarred fruit purees

Introduction. Chemicals in foods enter the human body from early life likely posing chronic toxic health risks in the future. This study aimed to estimate the exposure to ethanol and methanol in children consuming an acceptable daily amount of fruit purees. Methods. Different fruit purees were purchased and measured for methanol and ethanol by using HS-GC. The exposure dose of these alcohols was calculated based on a consumption of 125-250 g of fruit purees in children weighing 7, 12 and 16 kg. Results. The highest methanol was found in carrot-apple puree (29.07 mg/dL) and ethanol in peach-banana puree (42.07 mg/dL). Daily methanol exposure was estimated between 4.54 and 6.06, and ethanol between 6.57 and 8.76 mg/kg bw. Conclusions. Our results show higher exposure doses of methanol and ethanol than allowable ones (methanol 2 and ethanol 6 mg/kg/day) in children consuming fruit purees. This should be handled as a public health risk and further comprehensive studies should be enrolled on the chronic toxic effects of food-derived alcohols. Besides, food-derived exposure to toxic chemicals from early life should be more questioned by physicians (in assessing chronic diseases), and related authorities should establish a sustainable, safe, and healthy food production policy.
