Migration of aluminum from food contact materials to food鈥攁 health risk for consumers? Part II of III: migration of aluminum from drinking bottles and moka pots made of aluminum to beverages
Abstract Background Drinking bottles and stove-top moka pots made of aluminum have become very popular. Storing drinks in bottles and preparing coffee in a moka pot may result in the migration of aluminum to the beverage. Results/Conclusions In a systematic study of aluminum drinking bottles, it has been shown that drinking a mixture of apple juice and mineral water in an aluminum bottle may reach 86.6% of the total weekly intake (TWI) for adults, and drinking tea from an aluminum bottle may exceed the TWI (145%) for a child weighing 15聽kg. In contrast, preparing coffee in an aluminum moka pot results in a maximum of 4% to TWI, if an average of 3.17聽L coffee is consumed per week, even if the pots are washed in the dishwasher, against the explicit instructions of the manufacturer
Migration of aluminum from food contact materials to food鈥攁 health risk for consumers? Part III of III: migration of aluminum to food from camping dishes and utensils made of aluminum
Abstract Background When cooking on a barbecue grill, consumers often use aluminum grill pans. For one, the pan catches the fats and oils that would drip into the embers causing the formation of potentially noxious smoke, and the pan also protects the food from being burned by direct heat from the coals. In addition, new aluminum products for use in ovens and grills are becoming increasingly popular. Due to their light weight and excellent heat transfer camping, utensils made of aluminum are, for example, often used by fishermen and mountain climbers. Preparing food in aluminum utensils can, however, result in migration of the aluminum to the foodstuffs. Results/Conclusions In this study presented here, it was found that the transfer limit of 5.00聽mg/L for aluminum is not exceeded using simulants for oil or for tap water; however, with an aqueous solution of 0.5% citric acid, the limit is clearly exceeded at 638聽mg/L. This means that the Tolerable Weekly Intake (TWI) is exceeded by 298% for a child weighing 15聽kg and for an adult weighing 70聽kg it is equivalent to 63.8% of the TWI, assuming a daily uptake of 10聽mL marinade containing lemon juice over a period of 1聽week. Preparation of a fish dish with a marinade containing lemon juice in camping dishes would result in the TWI being exceeded by 871% for a child weighing 15聽kg and by 187% for an adult weighing 70聽kg assuming a daily uptake of 250聽g over a period of 1聽week
Migration of aluminum from food contact materials to food鈥攁 health risk for consumers? Part I of III: exposure to aluminum, release of aluminum, tolerable weekly intake (TWI), toxicological effects of aluminum, study design, and methods
Abstract Background In spite of the prevalence of aluminum in nature, no organism has been found to date which requires this element for its biological functions. The possible health risks to human beings resulting from uptake of aluminum include detrimental effects to the hemopoietic system, the nervous system and bones. Aluminum is used in many fields and occurs in numerous foodstuffs. Food contact materials containing aluminum represent an anthropogenic source of dietary aluminum. Results As a result of their frequent use in private households a study was undertaken to detect migration of this metal to foodstuffs from drink containers, coffee pots, grill pans, and camping cookware made of aluminum. Conclusions An estimate of the health risk to consumers is calculated, based on the tolerable weekly intake (TWI) specified by the European Food Safety Authority of 1聽mg/kg body weight for all groups of people. In some instances the TWI is significantly exceeded, dependent upon the food contact material and the food itself
