Establishment of probability assessment parameters of consumption of alcoholic beverage based on the contact area

ObjectiveTo support the probabilistic assessment of food contact materials with consumption parameters and methodology， the establishment of consumption data based on food contact area with different types of alcoholic beverages and different food contact materials was studied.MethodsBased on probability distribution， food contact surface area/volume ratio （S/V） data and alcoholic beverages consumption data were regarded as two independent distribution populations. Monte Carlo simulation was used to calculate the distribution of the food contact area based on consumption data. One thousand rounds of random sampling were conducted in the two populations to quantify the uncertainty.ResultsCategorized by alcoholic beverages-food contact material， beer-glass had the highest average food contact area based on consumption， with an average of 5.500 dm2/d and a 95%CI of 5.302-5.705 dm2/d. Categorized by food contact material， alcoholic beverages with aluminum coating had the highest average food contact area based on consumption， with an average of 5.213 dm2/d and a 95%CI of 4.929-5.532 dm2/d.ConclusionThe food contact area based on consumption data of alcoholic beverages can be the basic parameter for the probabilistic assessment of food contact materials of alcoholic beverages in China， which can be used for the accurate dietary exposure assessment.
