Aluminum speciation analysis of stewed meat
Sequential extraction procedure were used to analyze aluminum speciation in stewed meat. And the extraction conditions were studied. The result showed that in stewed meat, the largest proportion is organic aluminum, non-labile organic aluminum was about 15.2% in total, labile organic aluminum that extracted by (NH4)3C6H5O7 was about 23.3%, and extracted by NaOH was 32.6%. Al(OH)3 was the dominant proportion of inorganic aluminum, about 27.8%. The amount of inorganic monomeric aluminum was very little, only 0.9% in total.
