다시마를 Vibrio sp.로 분해하여 제조한 SCD를 첨가하여 수산 연제품을 만들어 그 특성을 분석하였다. 원료의 최적 배합 비율을 구하기 위하여 mixture program의 modified distance design을 적용하였다. 수리미와 SCD의 첨가량이 증가할수록 hardness와 cohesiveness 값은 감소 후 증가하였다. SCD의 첨가량이 증가할수록 hardness의 값은 증가 후 감소하였으나 cohesiveness 값은 감소 후 증가하였다. 수리미와 물의 첨가량이 증가할수록, SCD의 첨가량이 감소할수록 gumminess와 brittleness의 값은 증가하였다. SCD의 첨가량이 증가할수록, 물의 첨가량이 감소할수록 수분보유력과 백색도의 값은 증가하였다. 수리미의 첨가량이 증가할수록 백색도의 값은 증가한 반면, 수분보유력은 감소하였다. ANOVA 분석에 의한 다시마 SCD 어육 gel의 Hardness 및 cohesiveness는 nonlinear model(Quadratic model)이 결정되었으며, gumminess, brittleness, 수분보유력 및 백색도는 linear model이 결정되었다. Constraint coefficient 값의 분석 결과 수리미는 hardness 및 백색도에 가장 큰 영향을 미쳤고, cohesiveness, gumminess, brittleness에서는 SCD가, 수분보유력에서는 물이 가장 큰 영향을 미쳤다. Hardness는 surimi-SCD의 상호작용이 있었으며 cohesiveness에서는 surimi-water의 상호작용이 나타났다. Modified distance design에 의한 다시마 SCD 어육 gel의 수리미, 물 및 SCD의 최적배합 비율은 각각 36.80, 57.05 및 4.14%이었다.

This study was investigated quality properties of Sulgi with different mixed ratio of brown rice flour (BRF) and germinated brown rice flour (GBRF) by rheometer and sensory evaluation. Moisture contents of Sulgi with different mixed ratio of BRF and GBRF were 44.3~46.0%. In textural properties of Sulgi by rheometer, the higher BRF mixed level, hardness of those were higher. The higher GBRF mixed level, springiness, cohesiveness and gumminess of those were higher. In sensory evaluation properties of Sulgi, the higher BRF mixed level, flavor, firmness and graininess of those were higher. The higher GBRF mixed level, surface color, off-flavor, adhesiveness and cohesiveness of those were higher. Correlation between textural properties and sensory evaluation properties, hardness and firmness, graininess, cohesiveness and moistness, gumminess and surface color, gumminess and off-flavor, were correlated positively(p<0.01). Hardness and surface color, hardness and cohesiveness, hardness and overall quality, springiness and firmness, springiness and graininess were correlated negatively (p<0.01).

본 연구는 카제인 원료 대체를 위해 탈유당 탈지분유를 모방치즈에 사용하였을 때 야기되는 조직 특성의 변화를 관찰하였다. 카제인 원료 대신 탈유당 탈지분유를 일부 대체 사용한 결과 fracturability, elasticity, gumminess성질은 향상하였으나 hardness와 cohesiveness 성 은 감소하였다. 비슷한 결과로 calcium caseinate와 sodium caseinate를 원료로 모방치즈를 만들었을 때 탈유당 탈지분유를 사용한 모방치즈와 비슷한 조직특성을 나타내었다. 따라서 탈유당 탈지분유를 카제인 원료대신 일부 모방 치즈에 대체 사용할 수 있음을 확인하였다.

The mechanical characteristics (texture and color) and consumer preference of Doraji Yanggengs using different pre-treatments and added levels of Doraji were presently evaluated. Three kinds of Doraji Yanggengs were made with differing amounts of Doraji powder (DPY; 30, 50, or 70 g), ground raw Doraji (GRDY; 100, 200, or 300 g), and Doraji juice (DJY; 100, 200, or 300 g). Texture characteristics (hardness, adhesiveness, springiness, chewiness, gumminess, cohesiveness) and color values (lightness, redness, yellowness) were measured three times in three experiments conducted with each formulation. Preference was measured with a nine-point hedonic scale for Yanggengs once every three experiments. Consumer preference was measured with color, flavor, taste, appearance, texture, and overall acceptability. Significant differences according to the amount of Doraji powder were evident with DPY for hardness (p<0.001), adhesiveness (p<0.05), and cohesiveness (p<0.001). Hardness (p<0.001), adhesiveness (p<0.001), chewiness (p<0.01), and gumminess (p<0.01) of 100 g GRDY displayed higher scores than 200 g and 300 g GRDY, but displayed significantly lower scores in cohesiveness (p<0.01). Hardness (p<0.001), adhesiveness (p<0.001), chewiness (p<0.001), gumminess (p<0.01), and cohesiveness (p<0.05) of DJY showed significant differences according to amount of Doraji juice. The highest score in a preference test among DPYs was evident for 30 g DPY. There were no significant differences in preference among GRDYs and DJYs. Color, flavor, taste, appearance, texture, and overall acceptability were significantly (p<0.01) correlated in all Yanggengs. DJY was preferred more than DPY and GRDY. Women in their forties and fifties preferred Yanggeng more when compared to women in their twenties and thirties.

The objective of this study was to prepare acorn bread added with soymilk in order to improve its quality and develop the best possible recipe. The loaf volume, color, texture and sensory evaluation of acorn bread added with soymilk 10~40% were measured during the storage period. The L-value significantly decreased upon addition of 40% soymilk. A-value increased, but b-value decreased. During the storage period, the L- and a- values increased except 2 days at room temperature and 7 days in a freezer, whereas b-value decreased. For textural measurement, hardness, springiness, gumminess and brittleness increased significantly upon addition of soymilk. However cohesiveness decreased for 2 days of storage, whereas gumminess and brittleness for 1 day of storage at room temperature. Freezer storage for 1 day reduced cohesiveness, and gumminess for 4 and 7 days, respectively, and brittleness after all storage periods. The sensory evaluation showed that acorn bread added with soymilk 20% produced the best results in color and taste. The bitter aftertaste increased according to addition of soymilk with lower scores. Softness, chewiness and overall preference decreased significantly. Therefore, 10% soymilk addition got the best scores in aftertaste, softness, chewiness and overall acceptances.

The quality characteristics were measured, using sensory evaluation and mechanical characteristics, for the addition of different percentages of apricot juice(0%, 5%, 10%, 15%, 20%) to rice flour, in order to promote the use of and liking for the traditional Korean rice cakes. The pH was decreased with apricot juice addition, while acid was increased. The moisture contents were 36.2${\sim}$45.0% . The L-value was decreased with increasing apricot juice addition, while a- and b-values were increased. In mechanical texture characteristics, hardness, gumminess and brittleness were the highest at the 10% apricot juice level(p<.001). Springiness was also the highest at 10% level but the difference was not significant. In the sensory evaluation, the color, flavor, sourness, hardness and chewiness were increased with apricot juice addition. Apricot sulgidduk made with the addition of 10% apricot juice to rice flour was found to be the best recipe in terms of acceptability, flavor quality, taste quality, and overall quality and there was a significant difference between the samples. The springiness was negatively correlated with the cohesiveness, springiness, gumminess and brittleness while moistness was positively correlated with moisture, hardness, cohesiveness, springiness, gumminess and brittleness.

The textural characteristics of nonxaxy rice flour gels and rice cake(Injolmi) with different water contents and additives were evaluated after freezing and microwave heating. As moisture content of rice flour gels increased from 45% to 55%, its hardness and gumminess decreased, but adhesive and cohesiveness had no significant difference. Microwave heating did not markedly affect the texture but frozen storage was very effective to prevent the hardening of products. Hardness of reheated rice gels increased more rapidly in non-packaged sample than in PE wrap film and affected by storage time of 24hrs at 20$^{\circ}C$. As sugar content of rice flour gels increased from 0% to 10%, its hardness, adhesiveness, and gumminess decreased, while cohesiveness did not change.

In order to maks use of Adlay widely, it was analyzed and determined the content of amylose, amylopection. And Ju-ak was made from glutinous rice flours with vairous mixing ratio of Adlay flours and then this was tested for suitability to preparation of Ju-ak. Evaluation was conducted through sensory evaluation and objcetive evaluation. The results are as follow: 1. The content of moisture, total ash, crude protein, crude fat, and carbohydrate in Adlay were shown to be about 10.58%, 84.4%, 17.3%, 3.76%, 66.52%. 2. The amylose and amylopectin content were 15.6%, 84.4%. 3. By the sensory evaluation results the taste of Ju-ak prepared with mixing of 25% and 50% Adlay flour was better than glutinous rice Ju-ak but 75% and 100% mixed flour were undersirable. 4. By the Instron measurement results that hardness tend to increass as the additon level of Adlay increased. Gumminess, Chewiness and Elasticity was not significantly different as the addition level of Adlay increased. Conhesiveness tend to decrease as the addition level of Adlay. 5. Consistency of Ju-ak had significant relationship with hardness and cohesiveness. Moistness had significant relationship with hardness, elasticity, cohesiveness and chewiness. Texture of Ju-ak had significant relationship with hardness, elasticity, cohesiveness and gumminess.
