Yackwa is used as one of foods prepared for traditional rituals and holidays and enjoyed as snacks. Since Yackwas are fried, they contain oil, which can cause rancidity and undermines the freshness of Yackwas during distribution to retailers, not to mention a high level of calories. The study aims to develop baked Yackwas and analyze the quality in terms of calorie levels and characteristics by baking Yackwas in oven. Calorie level was 4.65 kcal/g in fried Yackwa, 3.96 kcal/g in baked Yackwa, and 2.95 kcal/g in baked peanut Yackwa prior to dip coating of grain syrup. baked Yackwa showed hardness of 13476.33 $g/cm^2$ before dipping in grain syrup, which was harder than 1912.56 $g/cm^2$ of fried Yackwa. After grain syrup coating, hardness of baked Yackwa reduced more significantly, compared with that of fried Yackwa, as grain syrup permeated through texture of Yackwa. And less hardness makes baked Yackwa tastier. Sensory evaluation was measured in a 5-point scale. Scores for texture and taste of baked Yackwa outpaced those of fried Yackwa. Score for the overall quality was 3.65 in baked Yackwa and 3.25 in baked peanut Yackwa, compared to 2.85 of fried Yackwa, indicating a higher potential of commercializing(p<0.05).

This study aimed to find oils that can replace high-priced sesame oil. The quality of baked Yackwa containing different types of oils (rice bran, olive, or sesame oils) and amount of oils (30, 35, 40%) were investigated. The hardness of the baked Yackwa depended on the amount of oil, as more oil led to a softer texture of baked Yackwa. According to sensory evaluations, baked Yackwa with rice bran oil received the highest score in taste quality, with sesame oil receiving the second highest score. The flavor of baked Yackwa containing the rice bran oil was also better than other samples. In contrast, there were no significant differences in taste between other samples, including baked Yackwa containing all ingredients, 40% sesame oil, and 40% olive oil. The overall acceptance showed the highest score in baked Yackwa with rice bran oil (35%). In conclusion, rice bran oil (35%) is recommended as an oil ingredient for baked Yackwa.

This study examined the effects of various oils used in the preparation of goami baked Yackwa dough on the quality characteristics of goami baked Yackwa. To determine the optimal amount of oil for goami powder Yackwa dough, the hardness and moisture contents of both the flour and goami powder dough were measured. Dough hardness was the highest in flour Yackwa while moisture contents was the highest in goami Yackwa. Baked weight and dip syrup weight were heavier in flour. Hardness, a-values, and b-values were the highest in flour Yackwa, whereas moisture contents and L-values was the highest in goami Yackwa. In a sensory evaluation, overall preference was the highest for goami Yackwa and flour Yackwa made with 10% oil.

The quality of baked Yackwa with rice bran oil varied with dipping temperature (80 and 25$^{\circ}C$) and dipping time (5, 10, and 15 minutes at 80$^{\circ}C$, and 60, 90, and 120 minutes at 25$^{\circ}C$). The moisture content and hardness of baked Yackwa increased and decreased, respectively, with dipping time. The expansion ratio increased with time when baked Yackwa was dipped at 80$^{\circ}C$, but decreased with time when dipped at 25$^{\circ}C$. Flavor and color were optimal for product dipped at 80$^{\circ}C$ for 15 minutes followed those dipped at 25$^{\circ}C$ for 120 minutes; the dipping conditions produced no significant difference in the degree of expension, aroma, texture, and overall quality. Baked Yackwa showed better results than fried Yackwa in sensory evaluation.

본 연구는 고아미로 만든 약과의 품질특성을 알아보고자 하였다. 밀가루에 고아미를 비율별로 첨가하여(100, 80:20, 60:40, 40:60, 20:80, 100) 약과를 만들고 집청전 후 무게, 경도, 수분 함량, 색도, 관능검사를 실시하였다(약과 반죽 14g: 12mm 몰드에 성형, 구운 온도: $160^{\circ}C$, 20Min., 집청: $60^{\circ}C$, 30Min.). 밀가루로 만든 약과의 집청전후의 무게가 가장 가벼웠고, 고아미의 첨가량이 증가할수록 약과의 무게가 유의적으로 무거웠다. 약과의 부피는 밀가루약과의 부피가 가장 컸고 고아미의 첨가량이 증가할수록 약과의 부피가 유의적으로 작아졌다. 수분 함량은 고아미 100%로만 만든 약과가 가장 컸다. 약과의 경도는 고아미를 첨가한 약과가 높았고, 씹힘성은 경도가 가장 낮은 밀가루로 만든 약과인 대조군이 가장 낮았고, 부착성과 탄력성, 검성과 응집성은 유의적인 차이를 보이지 않았다. 약과의 명도는 고아미의 첨가량이 증가할수록 낮아졌고, 적색도와 황색도는 고아미의 첨가량이 증가할수록 높아졌다. 고아미약과의 관능검사 결과 밀가루와 고아미가 비율별로 섞인 약과보다 오히려 밀가루만으로 만든 대조군이나 고아미만으로 만든 약과의 선호가 높았다. 또한 고아미 첨가량이 증가할수록 약과의 단맛이 강하고 촉촉하여 높게 선호되었다. 따라서 본 연구결과 밀가루를 대신하여 고아미쌀 만으로도 촉촉하고 팽화율이 비교적 높은 품질이 좋은 약과의 개발이 가능함을 알 수 있었다.

The quality characteristics of yackwa made with goami powder at different baking temperatures (150, 160, 170, 180) and baking times (15, 20, 25 min) and at different dipping temperatures (65 and $80^{\circ}C$) and dipping times (15 and 30 min) were evaluated. To determine the optimal temperature and time for yackwa containing goami powder, color values, preference color and pictures were determind. The baking temperatures were $150^{\circ}C$ for 25 min, $160^{\circ}C$ for 15 min and 20 min, and $170^{\circ}C$ for 15 min. The weight of yackwa was heavier at low dipping temperatures and long dipping times. L-values and b-values were the highest at short dipping times. Hardness, moisture and overall preference was the lowest at low dipping temperatures and long dipping times.
