[Study on factors affecting aluminium leaching from aluminium-utensils].

Temperature, pH, oxidative substances and other constituents in foods were studied on their effects on aluminium leaching from aluminium-utensils, using ICPAES method for determining the aluminium contents. The influence of heating on accelerating aluminium leaching was stressed and the effect of F- on aluminium leaching was confirmed. Fe3+ and NaCl were suggested for the first time as being able to promote aluminium leaching. The mechanism and practical significance of these effects are discussed.
