Abstract
$Prunus$ $mume$ was steamed for easier removal of the pulp. The steamed fruit pulp was vacuum dried and powdered. The steamed $Prunus$ $mume$ powder (SPP) was passed through a 250 ${\mu}m$ sieve, fluidized in a fluid-bed granulator, and then granulated by top-spraying with water (SPPGW) or the extract obtained from steam (SPPGE). Then the physicochemical and sensory properties of SPP, SPPGW, and SPPGE were evaluated. The flowability of powder (angle of repose $^{\circ}$) of SPP, SPPGW and SPPGE was $23.59^{\circ}$, $11.07^{\circ}$, and $13.94^{\circ}$, respectively. The water dispersibility of SPP, SPPGW, and SPPGE was 18.69, 10.04 and 6.00 sec, respectively. Also, the overall acceptance of SPP, SPPGW and SPPGE was 3.00, 3.44 and 6.56, respectively. In conclusion, SPPGE can be used as granular steamed whole fruit pulp with good powder flowability and dispersibility, and therefore consumer acceptance.
