Target compound was extracted with four different solvents, in which
acetone appears to be an excellent extractant as recovery of the analyte at 1 mg/g concentration in spiked
samples was in the range of 67.8e98.8%, with relative standard deviation (RSD) ranging between 4.8 and
6.6%. Intra- and inter-day assay precisions of the method at 0.1, 1.0 and 5.0 mg/g concentrations ranged in
between 3.4 and 8.9%. The linearities for b- carotene in the pure acetone, raw carrot, sweet potato, and
fortified raw and cooked chicken meat nuggets were 0.994, 0.995, 0.990, 0.984 and 0.984, respectively
