  • 단호박의 첨가수준을 10%, 15%, 20%, 25%, 30%, 35%로 달리하여 제조한 호박떡의 기계적 측정 및 관능적 특성을 통해 품질평가를 하였다. 호박떡의 수분함량은 단호박의 첨가량이 증가할수록 증가하는 것으로 나타났다. 색도의 경우 L 값은 단호박 첨가량에 의존하여 낮아졌으나, a 값과 b 값은 첨가량에 의존하여 증가하는 것으로 나타나 단호박의 첨가량이 증가할수록 carotenoids계 색소의 영향으로 황색 및 적색이 증가함을 알 수 있었다. Two bite compression test에 의한 물성특성치를 살펴보면, hardness, gumminess, chewiness 등은 단호박의 첨가량이 증가할수록 감소하는 경향을 나타냈고, cohesiveness 및 springiness는 각 시료간의 큰 차이를 보이지 않아, 단호박 첨가량이 증가할수록 조직의 견고도가 저하됨을 알 수 있었다. 관능검사 결과에서는 항목별로 유의적인 차이를 나타냈는데, flavor의 경우 유의성을 나타내지 않았으며, 이를 제외한 모든 항목, 즉 color, moistness, consistency, overall acceptance에서 30% 첨가구를 선호하는 결과를 보였다. 기계적 물성치와 관능적 물성치를 비교해 볼 때, 떡의 조직감이 견고한 것보다는 부드러운 것을 선호하는 것으로 나타났다.

  • The purpose of this thesis was to develop pumpkin soup with different ratios of ingredients, using high-nutrient sweet pumpkins. P10G0 without sweet pumpkin and glutinous rice powder showed the highest moisture content, whereas, P5G0 whit Cheongdung pumpkin and sweet pumpkin at the same ratio whitout glutinous rice powder showed the lowest moisture content. For chromaticity lightness of control pumpkin soup scored the lowest. Lightness of P10G0 without sweet pumpkin and glutinous rice powder also scored the lowest. For redness, the P5 group with Cheongdung pumpkin and sweet pumpkin at the same ratio scored the highest while the P10 group without sweet pumpkin scored the lowest. As for yellowness, increased ratio of glutinous rice powder in pumpkin soup scored resulted in reduced yellowness in all groups P5 (p<0.01), P7 and P10 (p<0.001) A higher ratio of Cheongdung pumpkin was thus generally associated whit reduced yellowness (p<0.001). For the spread-ability, higher ratio of sweet pumpkin to Cheongdung pumpkin resulted in significant reduction of spread-ability. However, groups with 12% glutinous rice powder showed no significant differences. Spread-ability of the P5 and P10 groups significant increased and thereafter decreased according to the addition ratio of glutinous rice powder, viscosity of the G0 and G4 groups decreased according to the addition ratio of Cheongdung pumpkin, whereas they first decreased and then increased in the G8 and G12 groups. All groups showed increased viscosity whit more glutinous rice powder. For the sensory evaluation, P5G8 was mostly preferred in all aspects. P7G4 was superior in all aspects except for flavor. P10G4 scored the highest in all aspects except viscosity. For acceptance test, except for the control group, P7G4 whit added of 70% Cheongdung pumpkin, 30% sweet pumpkin and 4% glutinous rice powder was the most preferred in all aspects except color (gloss, viscosity, flavor, taste and overall quality).

  • The mechanical and sensory characteristics of sponge cake made with different levels (0, 3, 6, 9, and 12%) of added sweet pumpkin powder were evaluated. The Hunter's L value of the crust and crumb of the sponge cake decreased significantly(p<0.05) as the content of pumpkin powder increased. Mechanical texture parameters such as hardness, gumminess and chewiness increased significantly (p<0.05) as the addition of pumpkin powder increased. Significant differences were observed in yellow color of crust and crumb, pumpkin flavor, sweetness and hardness in sensory evaluation of sponge cake added with 12% sweet pumpkin powder. The springiness of the sponge cake in sensory evaluation decreased significantly as the 12% addition of pumpkin powder (p<0.05). The highest overall acceptability was observed with 6% pumpkin powder added to the sponge cake.

  • This study aims to investigate the quality characteristics of breads with the addition of sweet pumpkin powder. Farinogram showed that the absorption rate of the dough decreased, the development time and stability became shortened, and the degree of attenuation tended to be grown along with increasing the amount of pumpkin powder. From the amylogram, it was found that the gelatinization starting temperature and the maximum viscosity of pumpkin powder added dough seemed to be decreased as the amount of pumpkin powder was increased. Extensogram showed that there was a decrease in the degree of extension of the dough added with increasing the amount of pumpkin powder, while an increase in the degree of resistance and resistance/extensibility. The lightness (L value) and redness (a value) of bread was found to be decreased with increasing the amount of pumpkin powder, while the yellowness (b value) increased. In terms of the dough texture, for which the hardness, cohesiveness and gumminess of the dough were measured, there were no significant differences between groups, while the dough added with 8.0% pumpkin powder showed a significant decrease in the elasticity. The results of sensory evaluation showed that the highest score of color (p<0.05) and taste (p<0.05) were obtained from the bread added with 6.0% and 8.0% pumpkin powder, while the highest score of texture in control and 3.0% pumpkin bread. In addition, the highest score of flavor (p<0.05) and overall acceptance (p<0.05) were observed in bread added with 6.0% pumpkin powder. Upon the results of this study, it was assumed that the development of food products using pumpkin are prospective in response to health-oriented consumers.

  • 순창식 식혜고추장의 담금 과정에서 식혜액 제조시 찹쌀의 일부를 건조완숙호박으로 대체하여(고추장 총 무게비로 1, 2, 5% 수준) 제조한 고추장을 $25^{\circ}C$에서 120일간 숙성시키면서 30일 간격으로 이화학적 특성 및 미생물 그리고 효소활성도의 변화를 측정하였으며 관능적특성은 숙성 120일째에 조사하였다. 숙성 중 고추장의 수분함량은 전반적으로 감소하였다. pH는 담금 초기부터 서서히 감소하다가 숙성 90일에 약간 상승하는 경향을 보였으나 그 후 다시 감소하였다. 적정산도는 숙성 중 서서히 증가하여 숙성 90일에 가장 높은 값을 나타내다가 숙성 120일에는 약간 감소하였다. 호박 첨가에 의해 고추장의 pH는 낮아지고 적정산도는 높아지는 것으로 나타났는데 이는 호박중의 유기산에 기인되는 것으로 판단된다. 숙성이 진행되는 동안 환원당 함량은 계속 증가하여 숙성 120일에는 대조구가 20.82%, 1% 호박첨가구가 21.34%, 2% 호박첨가구가 22.73% 그리고 5% 호박첨가구가 24.48%로 분석되었다. 아미노태 질소는 숙성 기간 중 서서히 증가하여 숙성 120일에 최고치를 나타내었다. 환원당과 아미노태 질소는 호박의 첨가량에 비례하여 높아졌으며, 에탄올 함량도 호박 첨가에 의해 증가하는 것으로 나타났다. 그러나 효모수나 세균수 그리고 효소 활성도는 호박 첨가에 의해 크게 영향을 받지 않았다. 관능적 특성에 있어 호박첨가는 고추장의 색에 좋지 않은 영향을 끼치는 것으로 나타났다. 냄새, 구수한 맛, 매운맛, 단맛, 짠맛 그리고 전체적인 기호도 등의 항목에서는 대조구, 1% 호박첨가구, 2% 호박첨가구 그리고 5% 호박첨가구 사이에서 통계적 유의성을 보이지는 않았으나 단맛의 경우에는 호박첨가량에 비례적하여 높아지는 경향을 보였고 구수한 맛의 경우에도 비슷한 경향을 보였으나 호박첨가량이 낮은 수준에서는 오히려 대조구에 비해 낮게 평가되는 등 다소 복잡한 양상을 보였다. 예상과는 달리 고추장의 전체적인 기호도는 호박첨가에 의해 향상되는 것으로 나타나지는 않았다.

  • This study investigated the quality characteristics, antioxidant activities, and retarding retrogradation of sponge cakes made with 0%, 1%, 3%, 5% and 7% pumpkin (Cucurbita moschata Duch.) leaf powder. Specific capacity significantly increased with the addition (0.33~0.38), but baking loss and dough yield were not significantly different (p<0.05). In color, there was a decrease in the L-value, a-value and b-value, but ${\Delta}E$ increased in proportion to the amount of pumpkin leaf powder. Moisture content increased in the 0~3% additions, from 27.90~31.68%, but decreased in 5% and 7% (22.37% and 28.15%, respectively). pH tended to decrease significantly according to the amount of pumpkin leaf powder (p<0.05). Hardness increased with the addition of pumpkin leaf powder, and pumpkin leaf groups presented higher springiness and cohesiveness than the control. Chewiness was not significantly differ (p<0.05). In retarding retrogradation, Avrami exponent (n) showed that addition of 5% (0.1329) had more retarding retrogradation effect than the control (0.4319), whereas time constant (1/k) showed both 3% (100.00) and 5% (70.42) addition had more effect than control (18.45). Total phenols and flavonoids content increased proportionate to the addition levels. ABTS radical scavenging activity tended to increase according to the level of pumpkin leaf powder. In sensory properties, 5% addition showed maximum color, and 3% addition had the highest scores in flavor, moistness, sweetness, chewiness and overall acceptability. These results suggested that pumpkin leaf was a good addition to improve the quality characteristics, health and sensory preferences. The most appropriate proportion to have the effect of retarding retrogradation in sponge cake is 3%.

  • The objective of this study was to investigate quality attributes of beef patties formulated with dried pumpkin pulp and seed mixture (PM). Four different meatball formulations were prepared where lean was replaced with PM as C (0% PM), P2 (2% PM), P3 (3% PM) and P5 (5% PM). Utilization of PM decreased moisture and increased ash content of the patties. Incorporation of 5% PM (P5) increased the pH value of both uncooked and cooked patties compared to C group. Increasing levels of PM increased water-holding capacity. No significant differences were found in cooking yield and diameter change with the addition of PM. Incorporation of PM increased fat and decreased moisture retention of the samples. $a^*$ values were decreased with PM addition, where $L^*$ values did not differ among treatments and $b^*$ values were similar in C, P3 and P5 samples. Textural properties were mostly equivalent to control samples with the incorporation of PM even at higher concentrations. The addition of PM did not significantly affect any of the sensory scores tested. These results indicated that utilization of PM presents the opportunity to decrease the amount of meat besides to improve healthier profile without causing negative changes in physical, chemical and technological quality of beef patties.
