  • The purpose of this study was to determine gain the most desirable mixture ratio for the ingredients of Backhapbyung. Sensory examination and mechanical test were conducted on the texture, water contents and color degree of Backhapbyung with various ratios of liliibulbs powder and sugar added to nonglutinous rice flour. The results of sensory evaluation showed that Backhapbyung composed of put 8% (24g) liliibulbs powder, 40g sugar, 40ml water and 276g nonglutinous rice flour had the highest overall score in terms of acceptability, after-swallowing and taste of flavor, and overall quality preference. Overall among the recipes tested, that with 6% (24g) liliibulbs powder, 40g sugar, 40 ml water and 282g nonglutinous rice flour showed the highest marks in springiness, cohesiveness, gumminess and chewiness. The moisture content was 33.54% nonglutinous rice flour, and 11.8% liliibulbs powder. The overall quality of sensory examination for bitterness was positively correlated with the hardness of sensory examination and the mechanical examination for adhesiveness. The overall quality of sensory examination for chewiness was positively correlated with the moistness of sensory examination and the mechanical examination for cohesiveness. From the above results, the best mixture ratio of Backhapbyung, with a moisture content of 37.18%, is 8% (24g) of liliibulbs powder, 40g sugar, 40ml water, and 3g salt and 276g nonglutinous rice flour.

  • A total of 284 milled rice (MR) marketed in Korea were analyzed for grading characteristics (head rice, broken kernels, chalky kernels, and damaged kernels%), color characteristics (L-, a-, b-values, and whiteness), protein content (%), and the cooked rice (CR) sensory quality to investigate the key characteristics affecting the overall sensory quality of rice marketed in Korea. Relatively high correlation with the overall sensory quality of the CR was found in color characteristics such b-value of the CR (r=-0.779) and MR (r=-0.545), the a-value of the CR (r=0.513), and the whiteness (r=0.298) of the MR, compared to protein (r=-0.150), and the moisture (r=0.158) contents of the MR and the percentage of head rice (r=0.195). Partial least squares (PLS) regression of the CR b-value with various characteristics of the MR showed that CR b-value was increased with MR b-value effectively, followed by protein content, damaged kernels, chalky kernels, and colored kernels of MR while it was decreased with whiteness and moisture content for the MR.

  • The effects of quality grade and storage time on physicochemical, sensory properties and microbial population of Hanwoo striploin beef were investigated. After a total of 30 Hanwoo beef were slaughtered, the cold carcasses were graded by official meat grader at 24 h postmortem. The carcasses were categorized into five groups (quality grade 1++, 1+, 1, 2, and 3) and were vacuum-packaged and stored. The samples were kept for 1, 4, 6, 8, 11, 13, 15, 18, 20, 22 and 25 d for analyses. As the quality grade was increased, moisture, protein and ash contents decreased (p<0.05). Higher quality grade corresponded with higher fat contents. The shear force values decreased with increasing quality grade and showed decreases sharply during the first 4 d (p<0.05). pH, water holding capacity, cooking loss, and volatile basic nitrogen for grade 1++ groups were lower than for grade 3 (p<0.05). CIE L* and b* values increased as increased quality grade (p<0.05). Meat color decreased until 13 d and fluctuated after 15 d of storage (p<0.05). Regarding the sensory scores, higher quality grade corresponded with higher juiciness, tenderness, flavor, fatty and palatability scores (p<0.05). Generally, increased storage time for 15 d improved sensory scores attributes. Results indicate that a high quality grade could positively influence physicochemical and sensory properties.

  • This study aims to analyze the factors that affect quality of life and sensory processing abilities in older adults. Participants were 121 older adults aged over 65. Quality of life was evaluated with Life satisfaction Index for the Elderly and sensory processing abilities were measured with Korean-AASP. Korean Activiy Card Sort was utilized to assess their activity level. Low positive correlations were found between quality of life and activity level in total score(p<.01), IADL(p<.05), leisure(p<.01), and social participation(p<.01). Correlation coefficients between quality of life and sensory processing abilities showed low negative correlations in low registration(p<.01), sensory sensitivity(p<.01), and sensation avoiding(p<.01), however, there were low positive correlations in sensation seeking(p<.05). The importance of sensory processing was highlighted from the findings of statistically significant correlations between quality of life and sensory processing abilities. This indicates that improvement of sensory processing abilities is critical in occupational therapy service for older adults. Furthermore, the findings of close relationship between activity levels and sensory processing abilities need to be reflected in senior welfare policy.

  • The purpose of this study was to evaluate quality characteristics of the bread added with chlorella growth factor(CGF). The bread was manufactured by adding 0.5%, 1.0%, 1.5% or 2.0% of CGF(w/w) to wheat flour. The bread volume was increased from 1,755mL to 1,840mL as CGF contents increased from 0% to 1.0%. The lightness(L values)and the redness(a values) decreased with increasing CGF contents, but the yellowness(b values) increased with increasing CGF contents. Textural characteristics of the bread were influenced by adding the CGF. The breads containing CGF showed a decrease in hardness, springiness, gumminess and chewiness. In sensory evaluation, sensory scores decreased with increasing CGF contents for color. On the other hand, the highest sensory scores for grain, flavor, taste, softness, chewiness, aftertaste and overall acceptability were obtained, when CGF content was 1.0%. In conclusion, the bread with 1.0% CGF was the best quality in textural and sensory evaluation.

  • The sensory quality and the baking property of blonds containing 10-50% of rice flour with wheat flour were analysed by QDA. As sensory characteristics, color, air cell size, air cell distribution, flavor, softness, chewiness and overall quality were evaluated. Bread could be made successfully even using up to 50% rice flour. The color, flavor, softness and chewiness were increased in rice-wheat bread especially using 10∼30% of rice flour, but in case of using 40∼50% of rice flour those characteristics were not significantly different from those of wheat bread. The size of air cell in 10∼30% rice-wheat bread was not significantly different but in 40∼50% rice-wheat bread it was increased. The distribution of air cell was more even in 10∼30% rice-wheat bread than in wheat bread, but not in 40∼50% rice-wheat bread. The overall quality of rice-wheat bread was shown to be better in 10∼30% rice-wheat bread than in wheat bread.

  • We evaluated chemical, sensory and mechanical properties of breads containing different amount of Paecilomyces japonica powder to provide the basic informations for the development of functional bread. The pH of dough with 2% Paecilomices japonica powder was the highest but the pH of dough with 3% Paecilomices japonica powder was the lowest. Baking loss rate of bread added 3% Paecilomices japonica powder was the lowest but that of bread added 1% Paecilomyces japonica powder was the highest in that. The result of sensory evaluation showed that bread added 1% Paecilomices japonica Powder was significantly more preferable in chewiness, mouth feel, texture quality and overall quality. Sensory properties of softness, wheat flour odor, moisture, and mouth feel were positively correlated with the acceptability. Mechanical properties of hardness and chewiness had negative correlation with sensory properties, but springiness, gumminess and brittleness had positive correlation with those. The results of various measurements and evaluations showed that the quality of bread containing the Paecilomices japonica powder could be well accepted organoleptically. And this in turn proves the possibility of functional bread by use of Paecilomices japonica.

  • Development of crops with high quality as well as various beneficial functions is necessary to satisfy consumers being interested in their health and to enhance a competitiveness in the international market of agricultural products. What we have achieved so far from our research on crop quality was not sufficient since we often neglected sensory feature of crop products such as eating quality but in many cases, we put more emphases on nutrient contents, physico-chemical properties, and out-appearing features of the products. Therefore developments of sensory elements and technique for evaluation with a priority given to eating quality of each of an individual crop are important and very urgent to be solved in Korea. An endeavor to develop bioactive crops is necessary and resonable but aspects of both productivity and economy with a special emphasis on the original purposes such as production of energy and nutrient for human life must be considered. The development of more concrete ideas for crop functionality is essential before any research goes further.
