residue without vortexing during addition, the highest partition
coefficient of anthocyanins was obtained. The differences among the
partition coefficients obtained from three different ATPE strategies
were small; the highest value was 8.69 and the lowest value was 7.86, but
the recovery and yield of anthocynins were highest when (NH4
)2
SO4
solution was firstly added to the fruit residue, and the mixture was
vortexed for 30 s before the addition of ethanol.
