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%.

동결건조 로얄제리를 이용하여 세립차를 제조하고자 가공특성을 조사하였다. 동결건조 로얄제리를 이용하여 총당에 대한 포도당 함량($X_1$, 0~100%), 에탄올 농도($X_2$, 75~95%) 및 에탄올 용액 분무량($X_3$, 8~12%)의 비율로 혼합하여 세립형성에 따른 수율, 교반에 의한 분쇄율 및 관능적 특성의 최적조건을 반응표면분석을 통하여 조사하였다. 최대 수율은 총당에 대한 포도당 함량 59.30%, 알콜 농도 88,64% 및 알콜 용액 분무량 11.83%일 때 89.99%로 높게 나타내었다. 교반에 의한 최소 분쇄율은 총당에 대한 포도당 함량 22.35%, 알콜 농도 77.21% 및 알콜 용액 분무량 10.59%에서 0.82%로 낮게 나타내었다. 전반적인 기호도에 대한 최대 관능평점은 총당에 대한 포도당 함량 31.81%, 알콜 농도 93.96% 및 알콜 용액 분무량 10.51%에서 7.45로 나타났다.
