The Determination of Aluminum Residue in Starch-Based Product
To investigate the feasibility of optimizing the national standard spectrophotometry for the determination of aluminum residue in starch-based products.The non dried starch-based product was digested by optimized wet digestion conditions,and the aluminum content in the sample was quantitatively determined with spectrophotometry.Measure the moisture content of the sample using an infrared moisture analyzer,and calculate the aluminum residue in the sample by deducting the moisture content.The results indicate that,the method can meet the requirements for the determination of aluminum residue in starch-based products.Compared with the national standard,the operation is faster and simpler.
