The home meal replacement (HMR) food industry began in 1980, and it has grown rapidly as a major food business for both consumers and the food industry since the development of industrialization and societal changes. Many researchers investigated a variety of HMR food product characteristics. On the other hand, previous studies have focused only on topics in limited study areas. Therefore, this study examined the effect of color marketing and the value of experience on the consumer behaviors. This study used a survey to collect the respondents' opinions about HMR food products. The study results showed that the characteristics of color marketing and the experience value of the HMR products influenced the consumers' attitudes. Moreover, consumers' attitudes affected their repurchase behavior. The results suggest that marketers of HMR food products should use colors that show the characteristics of products to appeal to consumers. In addition, HMR products should be developed in line with what consumers value the most; for example, consumers value their previous experience with the products and the characteristics of the products.

This study was performed in order to investigate the quality characteristics of sponge cake made with Laminaria japonia powder. To evaluate the physical and sensory analysis, Laminaria japonia powder was added to wheat flour in various ratio (3, 5, 7, 9%, w/w). The specific gravity and loss rate increased with the addition of Laminaria japonia powder. The crude protein and ash levels in the sponge cakes increased linearly with the addition of 0 9 g of Laminaria japonia powder/100 g of wheat flour. For the crumb color values, lightness (L) and yellowness (b) decreased with the addition of Laminaria japonia powder, whereas redness (a) significantly increased (P<0.05). In the texture analysis, the hardness, gumminess and chewiness were increased; however, the cohesiveness and resilience were reduced by the addition of Laminaria japonia powder. When the sensory characteristics were evaluated, 5% Laminaria japonia sponge cake showed the highest sensory properties, except for color. Therefore, the results suggested that 5% Laminaria japonia sponge cake could be helpful in improving the physical quality as well as the taste.

This study was conducted to investigate rheological and sensory characteristics of fish paste prepared with Curcuma longa L. powder (0, 1, 3, 5, 7%). The moisture content of the fish paste ranged from 71.35 to 72.97%. Increasing the amount of Curcuma longa L. powder in the fish paste tended to decrease the pH value and the folding test good score in all samples. Increasing the amount of Curcuma longa L. powder in the fish paste also tended to decrease the lightness (L) in the hunter color value, but to increase the redness (a) and yellowness (b). For the textural characteristics, the addition of Curcuma longa L. powder increased the strength and decreased the springiness. In a sensory evaluation, the addition of 3% Curcuma longa L. powder had the best score in taste and overall preference. Therefore, this results suggest that adding 3% Curcuma longa L. powder would be feasible for making Curcuma longa L. fish paste.

This study was performed to develop a therapeutic diet against aging and obesity, using Yangha(Zingiber mioga R.). Before development of a therapeutic diet, we performed cell viability assay, analysis of general composition, macrominerals and antioxidantive activities of Yangha. Based on the findings from analyzing the results, mook using Yangha powder(0～ 20%) was processed, and tested for quality characteristics such as color values, sensory evaluation and mechanical properties. The result of cell viability assay of myoga, using liver cells, revealed that within the concentration range from 500 ㎍/㎖ to 10, 000 ㎍/㎖, cell survivability increased in line with the concentration rate. Therefore, it will not be harmful to consume it as food. Regarding the normal substance of myoga, the water substance of myoga was 94%, which exceeds that of ginger and tumeric with 89% and 83%, respectively. As for crude protein, fat, carbon hydrates and ash, myoga contained less than the other two, which I think is due to the high water substance. Regarding the minerals, potassium had the highest contents among macrominerals of 234.74 ㎎%. As for the antioxidant test, hydroxy radical scavenging activity and superoxide radical scavenging activity were shown. As for the production of Yangha mook(Yangha powder levels were 0～ 20%) for quality characteristics, the more of the powder, the less the L, but the greater the a and b values. Also, for the material property, an increased amount of the powder, resulted in chewiness and springiness, but less gumminess in a correlated manner. However, there were no significant differences in the springiness and cohesiveness in relation to the powder. For the sensory test, jelly type ZM5 with 5% powder showed highest overall preference. According to the sensory test, based on the powder substance, the jelly with 5% powder showed the highest overall score, including preference.

본 연구는 실용테이블 데커레이션의 수준별 요소에 일정한 규칙의 색채변환을 주어 관찰자(응답자) 선호의 색채 테이블과 이미지 형용사, 심미성의 각 영향 요소간의 관계성 고찰로 이는 선행 연구인 '식음 테이블 데커레이션의 관찰자 선호도에 대한 조사 분석'의 검증연구이다. 연구결과로 색채 이미지와 선호도는 '고급스러운, 먹고싶은'의 이미지로, 중 저의 어두운 톤인 브라운 색채와 '따뜻한, 화사한' 이미지의 주황색 톤이 선호되었다. 선호도와 심미성 영향 요소와의 관계 평가에서는 일반인들은 '통일성, 게슈탈트'의 영향요소를 중요하게 인식하였고, 비전문가들은 '독특성'이 부각되었다. 본 연구는 자극물 선정에서 색채 변환에 의존함에 따라 T P O에 적합한 분위기 연출의 미흡 부적합 등 현실성의 문제점과 설문 응답이 이루어진 시기, 즉 계절, 세대 간 변수, 자극물 선정 등의 문제점이 제기되나, 실용 테이블 데커레이션에의 선호 디자인에 대한 프로세스를 제안함으로써 정성적 연출뿐만 아니라 정량적인 데이터를 이용한 새로운 디자인 방향을 제시하였다는데 의의가 있다.

영양고추시험장에서 분양 받은 고추 유전자원 523종에 대한 카로티노이드의 정성 및 정량 분석과 ASTA color 지수를 분석하였다. 개별 카로티노이드는 capsanthin, lutein, zeaxanthin, β-cryptoxanthin, α-carotene, β-carotene 등으로 동정하였다. 총 카로티노이드 함량은 0.5-84.8 mg/100g DW으로 나타났으며 ASTA color 지수는 0.7-233.1로 나타났다. 개별 카로티노이드의 평균갑과 총 카로티노이드 함량에 대한 비율은 β-carotene 5.0 mg/100g DW (24.8%) > capsanthin 5.0 mg/100g DW (24.7%) > zeaxanthin 4.1 mg/100g DW (20.4%) > β-cryptoxanthin 3.0 mg/100g DW (14.8%) > lutein 2.7 mg/100g DW (13.3%) > α-carotene 0.4 mg/100g DW (2.0%) 순으로 분석되었다. 카로티노이드 중 capsanthin의 함량이 ASTA color 지수와 높은 상관관계를 보였으며 (R2 = 0.723) capsanthin이 23.2 mg/100g DW으로 고함유된 자원 IT223599를 선발하였다. 또한 카로티노이드 크로마토그램의 패턴에 따라 고추유전자원을 7가지 그룹으로 구분하였으며 이는 고 색소 함유 품종 육종 등 다양한 산업 소재로 활용 될 수 있다.

녹차 품질평가의 한 요인이 되는 색도 평가 시 기존 평가 방법인 육안평가 혹은 색차 분석에 의존하고 있는 현행 분석방법을 신속, 간편하며 재현성이 높고, 녹차 품질관련 기타 성분과 동시분석이 가능한 녹차 색차 분석용 NIRS 검량식을 작성한 결과를 요약하면 다음과 같다. 1. 공시된 녹차 시료를 대상으로 색차계를 이용하여 색도 값(L, a, b)을 조사한 결과 검량식 작성용 시료는 L값이 평균 53.37(48.52~57.72 ), a값이 평균 -7.55(-10.02~-4.63 ), b 값이 평균 18.07(14.00~22.02 )을 나타내었고, 작성 검량식의 평가용으로 이용된 예견치 분석용 시료와 거의 동일한 범위를 나타내었다. 2. 녹차의 색차 분석용 NIRS 검량식을 검토한 결과 색차 중 명도에 해당하는 L 값은 원시 스펙트럼에 2차 미분(2nd derivative, 8 nm gap, 6 points smoothing, 1 point second smoothing)을 수행한 조건에서 R2 = 0.936으로 가장 우수한 양상을 나타내었고, 적색에 해당되는 색차 a값과 황색에 해당하는 b값은 1차 미분(1st derivative, 4 nm gap, 4 points smoothing, 1 point second smoothing)조건에서 R2 가 각각 0.991 및 0.958로 가장 우수한 결과를 나타내었다. 3. 최적의 녹차 색차 분석용으로 작성된 각각의 NIRS 검량식을 미지시료에 적용하여 정확성을 평가한 결과 색도값 L, a 및 b의 결정계수는 각각 0.905, 0.986 및 0.931로 매우 높은 상관을 보였으며, 이들 검량식은 향후 NIRS를 이용한 녹차 관련 연구 및 녹차 산업현장에서 품질관리를 위한 효율적 분석방법으로 활용이 가능할 것으로 판단된다.
