Abstract
A fine granule was prepared using freeze-dried royal jelly. For its preparation, which depended on operational parameters like its glucose-to-total sugar content ratio ($X_1$,0-100%), ethanol concentration ($X_2$,75-95%) and sprayed ethanol solution content ($X_3$,8-12%) using freeze-dried royal jelly, the response surface methodology was used to monitor the optimum conditions for the yield, the fragmentation rate with shaking, and the organoleptic properties. The maximum yield was 89.99% with a glucose-to-total sugar content ratio of 59.30%, an ethanol concentration of 88.64%, and a sprayed ethanol solution content of 11.83%. The minimum fragmentation rate by shaking was 0.82% at the glucose-to-total-sugar content ratio of 22.35%, the ethanol concentration of 77.21%, and the sprayed ethanol solution content of 10.59%. The sensory score for the overall palatability of the organoleptic properties was 7.45 at the glucose-to-total-sugar content ratio of 31.81%, the ethanol concentration of 93.96%, and the sprayed ethanol solution content of 10.51%.
