This study was conducted to develop a functional cookie with the addition of a sweet pumpkin powder on a cookie shape, that showed high preference level to all age group and that was very easily to store because of low moisture content, by substituting partially a sweet pumpkin powder for reducing content of wheat flour. This study has produced the sensory optimal composite recipe by making iced cookies, respectively, with each 5 level of Sweet pumpkin powder($X_{1}$), sugar($X_{2}$), butter($X_{3}$), by C.C.D(Central Composite Design) and conducting sensory evaluation and instrumental analysis by means of RSM(Response Surface Methodology). Sensory items showed very significant values in color, appearance, flavor, overall quality(p<0.05), texture(p<0.01), and instrumental analysis showed significant values in lightness, redness(p<0.01), yellowness, spread ratio, hardness(p<0.05). Also sensory optimal ratio of Sweet pumpkin cookie was calculated as sweet pumpkin powder 81.8g, sugar 116.6g, butter 210.7g, and it was revealed that the factors of influencing cookie aptitude were in order of Sweet pumpkin powder, butter, sugar.

This study was conducted to evaluate the effects of sweet pumpkin (Cucurbita Maxima D.) powder on the quality characteristics of cookies. The cookies were made with various sweet pumpkin powder levels (10%, 20%, and 30%). The pH of the dough increased while the density of the dough decreased as the amount of sweet pumpkin powder increased. The width of cookies determined by water content in dough increased with increasing sweet pumpkin powder level. The L value of cookies was significantly the largest in the control group. The b value was the highest for the 30% substituted sample group. According to textural measurements, the hardness, cohesiveness, springiness, and brittleness of the cookies with sweet pumpkin powder were higher in concentration than those of the control group. According to the sensory evaluation, the appearance, color, flavor, and texture of cookies with 10-20% sweet pumpkin powder were higher compared to those of the control group. The overall most acceptable cookie group was that with 10% added sweet pumpkin powder.

The purpose of this study was to provide the basic information on the functional cookies with pumpkin and ginseng powder. Pumpkin cookies with ginseng powder were prepared at various additions adding (0 g, 3 g, 6 g, 9 g). With increasing As the addition of ginseng powder additionincreased, there were significant decrease in the water contents and crude protein were significantly decreased (p<0.05). The spread factor and Hunter color's L, a, and b values in th dough and cookies were significantly decreased with increasing as the addition level of ginseng powder content was increased(p<0.05). Hardness measured using rheometer and onset, peak, and closing temperatures and gelatinization enthalpy using DSC showed significantly the higher values with increasing more additions of ginseng powder content. In sensory evaluation, surface cracking, and pumpkin flavor were decreased with lower levels of ginseng powder. Ginseng flavor and hardness were increased with lower levels of ginseng powder Overall desirability of cookies with addition of 3 g added ginseng powder was the highest of the four samplesproduction. Surface crakcracking washadhighly positively correlated with spread factor, a (redness) (p<0.01)and but negatively correlated with carbohydrate content (p<0.05). Ginseng aroma showed negative correlation to the water contents, crude protein, spread factor, and Hunter's a (redness) and b (yellowness) values (p<0.05).

소비자의 건강지향적인 요구에 부합할 수 있는 새로운 건강기능성 제품 개발에 응용하기 위해 버터, 대두유, 올리브유, 포도씨유의 유지를 달리하고 호박페이스트 첨가냉동쿠키를 제조하여 품질특성을 조사하였다. 쿠키 반죽의 특성으로 반죽의 pH를 측정한 결과 대조군인 버터가 pH 6.55로 가장 높았으며 올리브유, 대두유 및 포도씨유가 각각 pH 6.47, 6.43 및 6.46로 시료 간의 유의적인 차이는 나타나지 않았다. 반죽의 밀도는 버터가 1.37 g/mL로 가장 높았고 수분함량은 버터가 14.65%로 가장 낮았으며 올리브유, 대두유, 포도씨유의 수분함량은 비슷한 수준이었다. 쿠키의 퍼짐성을 측정한 결과 버터 쿠키가 가장 높았고 대두유 쿠키가 가장 낮았다. 쿠키의 색도의 경우 L값은 올리브유 쿠키, a값은 대두유 쿠키, b값은 포도씨유 쿠키가 가장 높게 나타났다. 쿠키의 경도는 대두유 쿠키가 698.26으로 가장 높았으며 버터 쿠키가 가장 낮게 나타났다. 쿠키의 관능적 기호도 평가에서 모든 평가항목에서 포도씨유 쿠키를 가장 선호하는 것으로 나타났다. 쿠키의 산화안정성으로 산가와 과산화물가를 측정한 결과 저장기간이 지날수록 식물성 유지가 버터보다 낮은 산가를 나타내어 산화억제 효과를 보였다. 과산화물가는 저장기간이 경과함에 따라 모든 시료에서 증가하였으며 버터 쿠키에 비해 포도씨유 쿠키가 증가의 폭이 가장 적었다. 이상의 결과를 종합해 보면 쿠키 재료 중 버터를 대신하여 식물성 유지인 올리브유, 대두유, 포도씨유 모두 대체 이용 가능하며 특히 건강기능성에 부합하고 산화안정성으로 효과적인 포도씨유 쿠키가 좋을 것으로 보인다.
