초록

대봉감 퓨레 첨가량을 달리하여 제조한 감 젤리는 대봉감 퓨레를 더 첨가할수록 조단백질, 조지방, 비타민 C, 식이섬유 및 베타카로틴 함량이 증가하는 것을 볼 수 있었다. 그러나 색도 결과 대봉감 퓨레를 더 첨가할수록 명도 값이 감소하였으며, 적색도 값은 퓨레 5% 및 7% 중량부를 첨가한 시료에서 유의적인 차이를 나타내지 않았다. 또한 조직감 결과 대봉감 퓨레를 더 첨가할수록 경도와 씹힘성이 증가하는 것으로 나타나 소비자들에게 불편함을 줄 수 있으며 관능검사 결과 외관, 색, 맛, 향, 씹힘성 및 전체적인 기호도가 퓨레 5% 중량부를 첨가한 것이 가장 높은 점수를 나타내었다. 대봉감 퓨레를 더 첨가할수록 영양학적으로 더 우수한 결과를 나타내었지만 색도, 조직감 및 관능검사의 결과 대봉감 퓨레를 첨가한 감 젤리의 개발은 퓨레 5% 중량부를 첨가하는 것이 가장 적합한 것으로 판단된다.

Physicochemical and sensory characteristics of persimmon jelly products with different levels (3, 5, and 7% w/w) of Daebong ripened persimmon puree was investigated. The moisture content of all jelly products used in this experiments was maintained within $8{\pm}2%$ of the products. Levels of crude chemical composition (moisture, crude protein, crude lipid, and crude ashes), texture, soluble materials, vitamin C, dietary fiber and ${\beta}$-carotene were increased as amount of puree addition increased in the products. Color values, $L^*$, $a^*$, and $b^*$ of the persimmon jelly products were 33.08-42.04, 0.93-1.31 and 8.85-11.21, respectively. There was no significant difference in pH (5.51-5.61) as the levels of Daebong ripened persimmon puree increased. Sensory evaluation in terms of appearance, color, taste, flavor, chewiness, and overall acceptance resulted in the highest score in the persimmon jelly product with 5% level of Daebong ripened persimmon puree. In conclusion, level of Daebong ripened persimmon puree affected color value, texture and vitamin C, dietary fiber, and ${\beta}$-carotene content of the persimmon jelly products. In addition, optimum level of Daebong ripened persimmon puree would be 5% for manufacturing the persimmon jelly product.
