Prunus mume is said to aid in the recovery of fatigue and improvement of liver and stomach functions. To obtain the best benefits of the whole fruit, fresh green Prunus mume was de-seeded and the fruit pulp was vacuum dried. The vacuum-dried pulp was powdered and sieved through a 250 ${\mu}m$ sieve. Then the sieved green Prunus mume powder (GPP) was granulated with water (GPPGW) and with Prunus mume extract (GPPGE) with a fluid bed coater. The physicochemical and sensory properties of GPP, GPPGW, and GPPGE were then evaluated. As a result, the water dispersibility (dispersible time) of GPP, GPPGW, and GPPGE was 21.19 sec, 6.46 sec, and 4.85 sec, respectively. The powder fluency (angle of repose) of GPP, GPPGW, and GPPGE was $11.25^{\circ}$, $8.65^{\circ}$, and $9.52^{\circ}$, respectively. The overall consumer acceptance of GPP, GPPGW, and GPPGE was 3.50, 4.62 and 5.00, respectively. Inconclusion, Prunus mume can be used as granulated whole fruit pulp with good powder fluency and dispersibility.

$Prunus$ $mume$ 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.
