The purpose of this study was to compare the physicochemical properties of sausage manufactured with carp (Carassius carassius) muscle and pork. Sausages were prepared using either 100% pork sausage (P10), a mixture of 50% pork and 50% carp muscle (P5C5), or 100% carp muscle (C10). The quality of the sausage emulsion was determined by analyzing approximate composition, pH, instrumental color, cooking yield, water holding capacity (WHC), viscosity, and texture profile analysis (TPA). Moisture content of cooked C10 was significantly higher than that of P10 or P5C5 (p < 0.05); however, protein content of cooked P10 was significantly higher than that of C10 (p < 0.05). The pH of uncooked and cooked C10 was significantly higher than that of P10 and P5C5 (p < 0.05). The cooking yield, WHC, and texture profile analysis of C10 were higher than those of P10 and P5C5 (p < 0.05). In addition, the viscosity of uncooked C10 was higher than that of P10 and P5C5. These results suggest that carp muscle can enhance sausage quality with respect to pH, WHC, cooking yield, viscosity, and TPA.

4개 상표의 즉석 쌀밥을 이용하여, 취반 후 30분 이내(0, 5, 10, 20, 30분)의 조직감 변화를 탐침이동 속도(0.5, 1 mm/s) 및 변형률(30, 70%)을 달리하면서 TPA방법으로 경도, 점착성, 응집성, 씹힘성 및 탄성 항목에 대해 측정하였다. 쌀밥의 조직감은 응집성, 점착성 및 씹힘성의 경우 취반 후 20-30분 경과 시, 취반 직후 시료와 비교하여 유의적 차이가 다수 발생하였으며, 특히 점착성은 취반 후 10분 경과 때부터 유의적 차이가 일부에서 나타난 반면에 탄성은 30분 경과 때에도 유의적 차이가 거의 발생하지 않는다. 결론적으로 쌀밥의 조직감을 측정할 경우 가급적 취반 후 10-20분 이내에 측정하는 것이 변화되지 않은 원래 쌀밥의 조직감 측정을 위해 바람직하다 하겠다.

The objective of this study was to determine the optimal conditions for preparation of cooked brown rice by blending brown rice, white rice and glutinous rice to improve the palatability. Formulations composed of brown rice (10~100%), white rice (0~90%) and glutinous rice (0~90%) were generated from an extreme-vertices of mixture experimental design, which showed ten experimental points for brown rice, with white rice and glutinous rice as the independent variables. The sensory evaluation, color, and texture profile analysis (TPA) of cooked brown rice and pasting characteristics of blending cereals flour were measured as response variables. Regression analysis showed that all responsible variables fit linear, quadratic or special cubic models (p<0.1), except for the cohesiveness of TPA. The goals of optimization of the blending ratio of brown rice, white rice and glutinous rice were given as appearance, flavor, texture and overall acceptability (lower: 5.50, target: 6.62). The optimal conditions were determined to be 34.55% brown rice, 42.71% white rice and 22.74% glutinous rice.

Purpose: Cheese texture is an important sensory attribute mainly considered for consumers' acceptance. The feasibility of nondestructive measurements of cheese texture was explored using non-contact ultrasonic sensors. Methods: A novel non-contact air instability compensation ultrasonic technique was used for five varieties of hard cheeses to measure ultrasonic parameters, such as velocity and attenuation coefficient. Five texture properties, such as fracturability, hardness, springiness, cohesiveness, and chewiness were assessed by a texture profile analysis (TPA) and correlated with the ultrasonic parameters. Results: Texture properties of five varieties of hard cheese were estimated using ultrasonic parameters with regression analysis models. The most effective model predicted the fracturability, hardness, springiness, and chewiness, with the determination coefficients of 0.946 (RMSE = 21.82 N), 0.944 (RMSE = 63.46 N), 0.797 (RMSE = 0.06 ratio), and 0.833 (RMSE = 17.49 N), respectively. Conclusions: This study demonstrated that the non-contact air instability compensation ultrasonic sensing technique can be an effective tool for rapid and non-destructive determination of cheese texture.

본 연구는 동물성과 식물성 시판 체다 치즈의 향미 특성과 조직감을 분석하기 위해 전자코와 전자혀 및 TPA 분석을 이용하였다. Milky, dairy, buttery, creamy, nutty, fruity의 향미속성을 바탕으로 전자코 분석 결과 확인된 화합물 5종을 주요 향기성분으로 선정하였으며, 모든 시료에서 acetaldehyde, 2-methylbutanal 및 n-butanol이 검출되었으나, 2,3-pentanedione과 pentan-2-one은 DT1, VT1 및 VT3에서만 검출되었다. 주성분 분석 결과 VT간에 군집을 이루지 않고 분산되어 있어 동일한 타입 내 시료 간 향기의 유사도가 떨어지는 것으로 나타내었다. VT의 맛 패턴은 DT와 유사한 경향으로 나타나지 않았으며, DT와 VT 내 시료 간에도 맛 패턴이 원재료에 의해 구분되지 않았다. 시판 체다 치즈의 조직감 측정 결과는 경도, 부착성, 탄력성 및 응집성 항목에서 생산 원료의 타입에 따라 구분되지 않는 것으로 나타내었으나, 조직감에 영향을 미치는 DT와 VT의 단백질 함량은 각각 18.0-20.0%와 1.0% 미만이었다. 본 연구결과는 동물성 치즈와 유사한 향미 특성과 조직감을 갖는 식물성 치즈 제품 개발의 기초자료로서 품질 지표 설정에 활용될 수 있을 것으로 판단된다.

The purpose of this study was to investigate the quality characteristics of makpyeon prepared with dry milled rice powder. The makpyeon samples prepared with dry milled rice powder and various amount makgeolli (0% (CON), 25% (M25), 50% (M50), 75% (M75), 100% (M100)), and analyzed for moisture content, pH, Hunter's color value, TPA and sensory evaluation. The moisture content did not showed significant difference among makpyeon samples. The L-value, a-value resulted in that CON showed the highest and decreased with the amount of makgeolli. The b-value of makpyeon samples showed that CON was the lowest and increased with the amount of makgeolli. TPA resulted in that M100 showed the highest hardness and the lowest adhesiveness, cohesiveness. Chewiness and gumminess of makpyeon samples were higher than those of CON. Based on quantitative descriptive analysis, the score of brightness, moistness, particle size and gloss of showed higher in CON that in makpyeon samples, firmness increased with the amount of makgeolli. Flavor attributes of liquor odor, sour odor, fermentation odor of makpyeon was stronger in makpyeon samples that in CON with the amount of makgeolli. Acceptance test resulted in makpyeon made with CON, 100% of makgeolli (M100) showed the significantly highest score in taste and overall acceptance.

In this study, the alkiline water washing condition of mackerel(Scomber japonicus) dark meat was investigated to improve processing conditions of red muscle fish meat paste heating gel. Chemical alkaline water(CWM) and electrolytic alkiline water(EWM, pH 12) were used for washing the mackerel raw meat. Washed meats were minced with 2.5% salt and heated at $90^{\circ}C$/15 min to testing texture profile analysis. Moisture of CWM and EWM was increased with both washing times(p<0.05). Crude lipids and protiens were decreased with washing times. Lightness of chemical alkaline water washed mackerel heated paste gel(CWHPG) was higher than electrolytic alkaline water washed mackerel heated paste gel(EWHPG). Redness and yellowness were more decreased than control meats. Jelly strength of CWHPG and EWHPG was not increased more than 2 times wased meat and was increased with protein decrease. Texture profile analysis, max force1 of CWHPG and EWHPG was higher hardeness than the control meat except gel strains. From these results, it could be suggested that electric alkialine water washing is also effective in advance the red meat paste heating gel process of kamaboko industry.

녹차를 이용한 기능성 면류를 제조하기 위해서 가루녹차를 밀가루에 1, 2, 3, 5, 7.5 및 10%첨가하여 제조한 생면의 품질 특성 변화를 조사하였다. 가루녹차의 첨가 농도가 증가함에 따라 아밀로그래프상의 호화개시 온도는 증가하였고, 최고 점도와 최종 점도는 감소하였다. 조리면의 성질도 가루녹차 첨가량이 증가함에 따라 무게와 부피는 상대적으로 감소함을 보였고, 탁도는 증가하였다. 표면색의 측정 결과 L값과 a값은 감소하였고, b값은 증가하였다. 조리면에 대한 TPA(texture profile analysis) 결과 가루녹차 2% 첨가까지는 견고성, 부착성, 탄력성, 씹힘성이 증가하였으나 3% 첨가부터 감소하였으며, 응집성은 첨가량이 증가함에 따라 감소하였다. 조리면의 관능검사 결과 가루녹차 1% 첨가시에 가장 좋은 품질로 평가되었다.

Noodle texture parameters of Korean style wet and dry noodles and relationships between noodle quality and flour characteristics were evaluated for two years, 1997 and 1998, and at two locations, Suwon and Deokso, using Korean winter wheat cultivars and lines. No significant difference for chewiness was found between cultivars over locations. Noodles made from flours from 1997 showed significantly higher chewiness than those from 1998. Chewiness of cooked noodles showed positively significant correlations with protein content and SDS sedimentation volume and negatively significant correlations with starch peak viscosity and flour swelling volume. Korean winter wheat cultivars, except for Gobunmil, Keumkangmil Tapdongmil, Suwon 265 and Suwon 280, showed chewiness of cooked noodles similar to commercial flours used for noodle making in Korea and Japan.
