This study was conducted to evaluate the effects of chestnut powder on antioxidant activity and quality characteristics of cookies. Cookies were prepared using different amounts of chestnut powder (0, 5, 10, 15 and 20% to the flour quantity). The antioxidant activity was estimated by measuring DPPH free radical scavenging activity and the total phenolic content in chestnut powder and cookies. In addition, the quality characteristics of the chestnut cookies were estimated based on: the bulk density and pH of the dough, spread factor, loss rate, leavening rate, color, texture profile analysis, and sensory evaluations. The spread ratio, a values, total polyphenol contents, and DPPH free radical scavenging activity of cookies significantly increased with increasing chestnut powder (p<0.001), while the leavening rate, L values, b values and hardness of the cookies significantly decreased with increasing chestnut powder (p<0.05). The sensory evaluation scores for the 15% chestnut powder cookie groups ranked significantly higher (p<0.05) than the other groups in overall preference, appearance, taste, color, chestnut taste, oily flavor, and aftertaste. Taken together, the results of this study suggest that chestnut powder is a good ingredient for increasing the consumer acceptability and functionality of cookies.

This study was conducted to investigate the effect of chestnut inner shell powder on antioxidant activity and the quality characteristics of cookies. Cookies were prepared with different amounts of chestnut inner shell powder(in ratios of 0, 0.5, 1, 3 and 5% to the flour quantity). The antioxidant activity was estimated by DPPH free radical scavenging activity and the total phenol content in chestnut inner shell powder and cookies. For analyzing quality characteristics, bulk density and pH of the dough, spread factor, loss rate, leavening rate, color, texture profile analysis, and sensory evaluations were measured. The spread ratio, a values, total phenol contents and DPPH free radical scavenging activity of cookies significantly increased with increasing chestnut inner shell powder(p<0.001), while the pH of the dough, L values and b values of the cookies significantly decreased with increasing chestnut inner shell powder content(p<0.001). The consumer acceptability score for the 3% chestnut inner shell cookie groups ranked significantly higher(p<0.01) than those of the other groups in overall preference, flavor, taste and color. From these results, we suggest that chestnut inner shell is a good ingredient for increasing the consumer acceptability and the functionality of cookies.

본 연구에서는 부산물인 율피를 이용해 쿠키를 제조하여 그 품질특성을 조사하고 식재료로서의 가능성을 알아보고자 하였다. 쿠키는 제조 시 사용되는 밀가루에 대해 율피가루를 0%, 10%, 20%, 30%, 40% 첨가하여 쿠키를 제조하였으며, 모든 쿠키는 $180^{\circ}C$에서 10분간 예열된 오븐에서 20분 동안 구웠고, 구운 쿠키는 상온에서 24시간 동안 식힌 후 실험에 이용하였다. 제조한 쿠키는 수분함량, 굽기 손실률, 퍼짐성, 색도 측정, 경도 측정과 관능검사를 실시하여 각 쿠키의 품질 특성을 알아보았다. 그 결과 율피가루를 첨가한 쿠키의 수분함량은 율피가루 함량에 따라 유의적인 차이가 나타냈으며(p<0.001), 쿠키의 퍼짐성과 색도의 L값(밝기)와 b값(황색도)는 율피가루 함량이 증가할수록 감소되어 실험군간의 유의적인 차이를 보였으나(p<0.001) 반면 쿠키의 경도와 적색값은 쿠키 제조 시 율피가루 함량이 증가할수록 유의적인 차이를 보이며 증가하였다(p<0.001). 관능평가 결과, 율피가루 20% 첨가 쿠키가 색, 조직감, 전체적인 기호도면에서 다른 실험군에 비해 가장 높은 점수를 나타내었다. 따라서 위의 실험결과를 정리하면 율피가루를 첨가한 쿠키 제조 시 율피가루 대체 비율은 20%가 가장 적합한 것으로 나타났고 율피가루는 소비자의 기호를 충족시키고 기능성을 증가시키는 데 있어 쿠키의 좋은 재료가 될 것으로 여겨진다.

Chestnut flours (CFs) were produced from 3 chestnut samples (Aydin, Kutahya, and Bursa) by 2 different methods (boiled and oven-dried: BOD-CF and freeze-dried: FD-CF). Functional properties and effects of CF addition (10, 20, and 30%) on the qualities of regular and low-fat cookie were investigated. The freeze drying significantly increased water solubility of CFs but decreased their water binding capacity. The emulsion capacity and stability of FD-CFs were higher than those of BOD-CFs. At pH 4, 6, 8, and 10 FD-CFs had better gelation properties. Spread ratio (SR) values of BOD-CF supplemented regular or low-fat cookies decreased with increasing CF levels. Hardness values of CF supplemented regular cookies were generally lower compared to control. SR and hardness values of FD-CF supplemented cookies were higher than those of BOD-CF supplemented ones. Surface colors of the cookies were darker with FD-CF addition as compared to BODCF addition. In low-fat cookies, the sample supplemented with 10% Kutahya FD-CF had the highest taste-flavor value. FDCF supplementation generally resulted in higher appearance and taste-flavor scores than BOD-CF supplementation in cookies.

본 연구는 항산화성이 우수하나 버려지는 율피의 이용 증대를 위해 숙성시켜 파우더로 만든 후 쿠키에 첨가(0.25%, 0.5%, 1%)하여 품질 특성 및 항산화성을 분석하였다. 숙성 흑율피 첨가 쿠키의 수분 함량은 숙성 흑율피의 첨가량이 증가할수록 수분 함량도 같이 증가하였다. 가용성 고형물 함량과 환원당 함량은 숙성 흑율피의 첨가량이 증가할수록 높아졌다. 명도는 숙성 흑율피 첨가량이 증가할수록 낮아지는 경향을 보였으며, 적색도는 숙성 흑율피 첨가량에 따라 증가하였다. 황색도는 숙성 흑율피 첨가량에 따라 낮아지는 경향을 보였다. pH는 숙성 흑율피의 첨가량이 증가할수록 낮아졌으며 산도는 높아지는 경향을 보였다. 숙성 흑율피 쿠키의 조직감은 강도에서만 각각에 유의적이 차이를 보였으며 씹힘성에서는 유의적 차이를 보이지 않았다. 총페놀의 함량은 숙성 흑율피의 첨가량이 증가함에 따라 증가하였다. DPPH 라디칼 및 hydroxyl 라디칼 소거능은 숙성 흑율피 첨가량이 증가할수록 $IC_{50}$ 값이 낮게 나타나 항산화능이 증가하였다. 관능검사 결과 색상, 거침성, 숙성 흑율피의 이질성, 숙성 흑율피의 향, 숙성 흑율피의 맛은 숙성 흑율피의 첨가량이 증가할수록 높은 점수를 받았으며, 버터향과 단맛은 숙성 흑율피의 첨가량이 많을수록 낮게 나타났다. 기호도 특성 결과 전체적인 기호도와 구매의향은 0.5%의 숙성 흑율피를 첨가하였을 때 가장 높게 나왔다. 이상의 결과로부터 숙성 흑율피를 쿠키에 첨가 시 0.5% 수준으로 첨가하는 것이 바람직한 것으로 생각되며, 폐기하던 율피의 이용도를 증대할 수 있는 바람직한 방법이라 생각한다.

This article examines the types and cooking methods of Suksilkwa as recorded in 14 royal palace studies and 10 old literature texts of the Joseon dynasty (1392-1909). The types of Suksilkwa during the Joseon dynasty were Joran (棗卵), Yulran (栗卵), and Gangran (薑卵). The frequency of the Suksilkwa types during the Joseon dynasty in order were: Gangran (35.4%), Joran (32.3%), and Yulran (32.3%). Prior to 185 years ago, "Junghae-Jungraeeuigwe (丁亥整禮儀軌)" (1827), Joran (棗卵), Yulran (栗卵), and Gangran (薑卵) were called Samsaegran (三色卵). Nearly 144 years ago, "Mujin-Jinchaneuigwe (戊辰進饌儀軌)" (1868) recalled sulsilgwa (熟實果). "Imjin-Jinchaneuigwe (壬辰進饌儀軌)" (1892) first recalled assorted-sulsilgwa (各色熟實果), in which sansabyeong were added in the sulsilgwa. "Sinchuk-Jinyeoneuigwe (辛丑進宴儀軌)" (July 1901), "Imin-Jinchaneuigwe (壬寅進饌儀軌)" (April 1902), "Imin-Jinyeoneuigwe (壬寅進宴儀軌)" (November 1902) described assorted-sulsilgwa (各色熟實果) in which ohmijabyeong were added to the sulsilgwa. Further study will be conducted on recipes and ingredients recorded in these Euigwe and old books in order to develop a standardized recipe to make Suksilkwa appealing to a global palate.
