It was also observed that the higher pKa values of food additives, the less recoveries
sacrificed, i.e., acesulfame (pKa = 2.0) with recovery decreased
from 93.5% to 39.8%, saccharin (pKa = 2.0) from 94.2% to 41.0%, benzoic
acid (pKa = 4.2) from 93.2% to 61.8%, sorbic acid (pKa = 4.2) from
95.9% to 58.6% and dehydroacetic acid (pKa = 5.3) from 94.2% to
71.6%, respectively.
