  • The aim of this research was to evaluate the effects of rosemary and kimchi powder on the quality characteristics of pork patties. Cooked pork patties was stored at $3^{\circ}C$ for 15 days. Rosemary powder, either alone or with Kimchi powder, was highly effective in inhibiting lipid oxidation. The AV and TBARS values of R4(additional group of 4% rosemary powder) and RK(additional group of 2% rosemary powder +2% kimchi powder) were slightly lower than those of the control group. Sensory preferences for pork patties decreased with increased of storage time period. In a sensory evaluation, R4 showed the low sensory scores, whereas RK was highly evaluated compared to control. In conclusion, we determined that the pork patties with added 2% rosemary powder and 2% kimchi powder had the most favorable antioxidant effects and sensory qualities.

  • The aim of this study was to determine the optimum amount of perilla leaves to add to rice flour in the preparation of Sulgidduk(perilla leaf rice cake). By increasing the perilla leaf level in the formulation, the moisture contents of samples increased ($42.06{\sim}48.17%$), and their L-values decreased. The control and 16% perilla leaf Sulgidduk had higher a-values than the other samples, and the 8% perilla leaf Sulgidduk had the highest b-value. According to the mechanical evaluation results, hardness, gumminess, chewiness, and fracture decreased with increasing amounts of added perilla leaf. However, the springiness of samples during storage did not differ significantly according to the level of added perilla leaves. From the sensory evaluation results, the 12% perilla leaf sample received the highest overall-acceptability scores. In conclusion, according to its sensory and mechanical qualities, the optimal Sulgidduk formulation consisted of 12% perilla leaves added to rice flour.

  • To study the visual evaluation on the effect of ruffle's gather, the aesthetic evaluation on the gather's measurements and the image evaluation were performed. Evaluated fabrics were cotton, wool ani synthetic fiber, and 3 kinds of thickness for each fabric were selected. In order to seek for aesthetic gather's measurements, we performed the sensory test by the Rank Method on 5 kinds of gather's measurements(I.5 times, 1. 8times, 2times, 2.5 times, 3 times). For the image evaluation on the effect of the gather, we performed the sensory test by the Semantic Differential Method on the gather's measurements were got high score in the sensory test of the gather's measurements and analyzed by means of a Factor Analysis. The results were as follows. 1. Except 2 times of fabric $A_1$(thin cotton), the aesthetic gather's measurements of the ruffle were evaluted 2.5 times in cotton and synthetic fiber, and 2 times in wool. Generally the aesthetic gather's measurements of the ruffle were 2$\~$2.5 times. 2. The image characteristics of the ruffle were established the characteristics of the fabrics as factor 1, the characteristics of the atomosphere as factor 2 and the characteristics of the drape as factor 3. Therefore, we must consider the characteristics of the fabric, the atomosphere and the drape of the ruffle in production of the ruffle.

  • The purpose of this study was to investigate the quality characteristics of Gamgyul-Injeulmi containing different ratios of Citrus mandarin powder(0, 3, 6, 9 and 12%). The moisture content of the control group was 45.37%. As the ratio of Citrus mandarin powder increased, moisture content decreased. The water holding capacity of glutinous rice flour with Citrus mandarin powder decreased gradually in proportion to the amount of Citrus mandarin powder added. An analysis of Hunter's color values for Gamgyul-Injeulmi indicate that the addition of Citrus mandarin powder leads to lower L value and higher a and b value compared to the control. Textural analysis of Gamgyul-Injeulmi showed that the hardness, cohesiveness, gumminess and chewiness increased as Citrus mandarin powder was added, whereas adhesiveness and springiness decreased. According to the sensory evaluation of Gamgyul-Injeulmi, as the ratio of Citrus mandarin powder was increased, the flavor, sweetness and hardness all increased. Gamgyul-Injeulmi with 6% Citrus mandarin powder was rated as the best in terms of color and for overall preference in the sensory evaluation.

  • 본 연구에서는 고아미 2호의 흰죽의 제조조건을 기본으로 하여 기능성 식품으로의 활용 가능성을 알아보기 위해 여러 기능성이 알려진 흑임자를 이용하여 흑임자죽의 품질 특성을 알아보았다. 흑임자죽에서는 흑임자의 첨가비율이 증가할수록 명도가 낮아졌으며 b값도 낮아졌다. 점조성 측정 결과, 흑임자의 첨가비율, 물의 첨가비율이 증가할수록 죽의진행거리가 길어져 점성이 감소하였다. 회전 원통형 점도계의 측정 결과에서도 흑임자의 첨가비율, 물의 첨가비율이 증가할수록 점도가 감소하여 점조성과 같은 경향을 보였으며 전분의 양과 쌀을 기준으로 한 물의 첨가비율에 따른 것이라고 생각된다. 관능적 특성의 검사 결과 흑임자와 물의 첨가량에 따라 검은색, 표면 광택, 고소한맛, 떫은맛, 쓴맛, 점도, 색, 맛, 점도에 대한 기호도 및 종합적인 기호도 모두에서 유의적인 차이가 있었다(p<0.001). 고소한 맛은 흑임자의 첨가비율이 증가할수록 증가하였으나 60%에서는 40%와 큰 차이가 나타나지는 않았다. 색에 대한 기호도, 맛에 대한 기호도, 점도에 대한 기호도, 종합적인 기호도에서는 흑임자의 비율 40%, 물 1,200 mL일 때가 모두 가장 높은 기호를 나타냈다. 점도는 흑임자와 물이 증가할수록 감소하는 결과가 나왔고 이는 기계적 측정인 점조성(p<0.001)과 점도(p<0.05)와 높은 상관관계를 보여 관능적 특성의 점도를 예측하는데 두 특성을 이용할 수 있을 것이라고 생각된다. 관능적 특성의 검은색과 표면 광택의 결과는 색차계의 L값과 b값과 상관관계를 보였다. 이러한 결과로 볼 때, 고아미 2호를 기반으로 한 흑임자죽의 최적 조리조건은 흑임자와 고아미 2호를 4:6의 비율로 하고 물의 첨가량은 1,200 mL이라고 할 수 있겠다. 본 연구에서 개발된 흑임자죽은 기능성은 있지만 가공적성 및 이취 등의 관능적 제한점이 있는 고아미 2호의 소비를 늘리기 위한 방안의 일환으로 일조할 수 있을 것으로 사료된다.

  • The quality characteristics of tofu added Ligularia fischeri powder (LFP) were investigated. The proximate composition of LFP used was as follows: moisture, 7.7%; crude protein, 12.0%; crude lipid, 5.9%; crude ash, 14.1%; and carbohydrate, 60.3%. The yield of tofu added LFP increased with the addition of LFP. However, there was a significant decrease in pH (from $6.03{\pm}0.11$ in the control to $5.78{\pm}0.11$ when 0.4% LFP was added) and a significant increase (from $2.60{\pm}0.01$ in the control to $2.85{\pm}0.10$ when 0.4% LFP was added) in total acidity. In addition, the L, a, and b values of tofu decreased with the increasing addition of LFP. In terms of textural properties, the hardness, cohesiveness, and brittleness increased, whereas springiness decreased, with the increasing addition of LFP. In the sensory evaluation, the overall preference for tofu added 0.3% LFP was the highest. According to the results, the addition of LFP positively affects the overall sensory evaluation of tofu, and 0.3% is the optimal level for addition.

  • 난황의 첨가수준을 달리하여 제조한 약과의 저장기간에 따른 기계적, 관능적 품질특성을 평가하였다. Texture profile analysis에 의한 물성특성의 경우 난황첨가량 및 저장기간에 따라 시료간의 유의적인 차이를 보였는데, 난황 첨가량 및 저장기간이 증가함에 따라 그 값이 증가하여 약과가 단단하게 경화되는 것으로 나타났다. 색도의 경우 난황첨가량에 따른 차이를 보였으며, 저장기간이 경과함에 따라 약과의 명도 및 적색도는 양의 방향으로 증가하였고, 황색도는 음의 방향으로 증가하는 것으로 나타났다. 관능적 품질의 경우 관능검사 결과 20g의 난황 첨가시 약과의 종합적인 기호도가 높은 것으로 나타났으며, 30-40g의 난황첨가는 관능적 품질을 저하시키는 것으로 나타났다. 또한 약과에 난황첨가시 색, 외관, 맛 등에는 큰 영향을 미치지 않는 것으로 나타나 약과의 전통적인 맛 및 외관을 유지하면서도 영양적으로 우수한 약과를 제조할 수 있었다.

  • This study was performed to investigate the quality characteristics of Yakpyun with added brown rice. The Yakpyun was prepared with polished rice, brown rice, Jujube paste, Makkolli, sugar and salt. The Yakpyun was made with various levels (0, 20, 40, 60 or 80%) of added brown rice. After making the Yakpyun, it was examined for the effect of adding brown rice on quality characteristics using scanning electron microscopy (SEM), a mechanical test, and a sensory evaluation. The moisture contents of Yakpyun tended to decrease with increasing amounts of added brown rice, but no significant differences were observed. As the content of brown rice increased, the lightness (L) decreased and redness (a) and yellowness (b) increased. In a texture profile analysis, hardness decreased with increasing brown rice content from the moment of production to 3 days of storage. When more brown rice was added, rough surfaces were found more often under SEM, and large holes were evident between granules. The results of the sensory evaluation showed that overall acceptability was the highest for Yakpyun containing 40% added brown rice.

  • The effects of intramuscular fat on the sensory characteristics of M. longissimus dorsi in Japanese Black steers were investigated by a trained analytical panel (average 13.4 panelists). Five sets (10 head) of artificial identical twins were divided into 2 groups, high level of intramuscular fat group (HG) which utilized the fattening method of increasing intramuscular fat and low level of intramuscular fat group (LG) which did not use the above method. Regarding M. longissmus dorsi which was produced for use in the sensory evaluation, crude fat contents of HG and LG was 25.8% and 23.2% respectively (p<0.05). Warner-Bratzler shear force, water holding capacity, cooking loss and fatty acid composition of HG and LG were similar between the two groups. M. Longissimus dorsi taken from HG and LG were tested for their sensory characteristics by a trained panel. HG was given higher points for juiciness than LG (p<0.05). There were no significant differences for tenderness and flavor between the two groups. Overall acceptability which synthesized each of the sensory characteristics of HG and LG were 5.04 and 4.69 points respectively (p = 0.05). These results suggested that juiciness increased with the increase of intramuscular fat, and this raised the overall acceptability of M. longissimus dorsi.
