Determination of Calcium Propionate in Complex Food Additives by UPLC
UPLC was applied to the determination of calcium propionate in order to avoid the interference of complex food additives on the titration results. The result showed a linear relationship between quality of propionic acid concentration in the range of 0.05 ~ 1.00 g/l and its peak area, in which LOQ was 0.05 g/kg, recovery was 97.3 ~ 103.4% and RSD was less than or equal to 2.9 %(n=6). UPLC was an ideal test method for determination of calcium propionate in complex food additives with its accuracy, high sensitivity, and simple sample pretreatment.
