  • The objective of this study was to evaluate the effect of the amount of water and several kinds of sweeteners on the texture such as grain appearance, softness, moistness, chewiness, cohesiveness, gumminess and elasticity of Backsulgi when one manufactures Backsulgi. Different amount of water of 30 ml, 60 ml and 90 ml/350 g of powdered rice and such sweetners as sugar, honey and syrup were employed for the experimental treatments. The evaluation of these results were dependent on statistical data of some scores that were obtained through sensory evaluation and Instron Universal Testing Machine. According to this sensory evaluation, the texture of Backsulgi was more affected by the change of water quantity than that of sweeteners. Judging from the results of Instron Universal Testing Machine, it was found that there were no statistically significant differences in each treatment of the cohesiveness, elasticity and hardness of Backsulgi, but some statistically significant difference was observed in each treatment of the gumminess and chewiness of Backsulgi(p<0.05).

  • The purpose of this study was to identify the evaluative criteria for leather garment and investigate differences among the evaluative criteria of consumer groups, which were categorized by consumers' lifestyle. A questionnaire was developed and administered 475 males and females from twenties to forties living in Seoul and Daejon during August in 2001. Data were analysed by frequency, factor analysis, cluster analysis, t-test and one way-ANOVA. The results were as follows: 1. The leather garment evaluative criteria were found to have four different dimensions: a) aesthetic, b) sensory properties and quality, c) practicality, and d) symbolism. Especially, the sensory properties and quality including the weight of the leather garment, odor, and hand feel were identified as distinctive evaluative criteria for leather garment compared with general garments. 2. The leather garment evaluative criteria were used differently according to consumers' lifestyle. Consumers with a passive lifestyle tended to consider economic efficiency and practicality. The confident and active consumers with interests in their appearances tended to buy leather garment for symbolic and aesthetic reasons. 3. There were significant differences in evaluative criteria for the leather garment among demographics-gender, age, and marital status.

  • The purposes of this study were to : (a) analyze the portion size & plate waste of normal & soft diets provided by dietetic departments in hospital, (b) investigate the factors affecting plate waste, and (c) determine the nutritional & monetary value of plate waste. A questionnaire for food preference and sensory evaluation was developed and a survey was carried out for the 46 normal diet and 56 soft diet patients in Sanggye Paik hospital in Seoul. Serving size and plate waste were weighed by the electric scale, and CAN-Pro program was used to evaluate the nutrition value. The data were analyzed using the SAS package program for descriptive analysis, t-test, ANOVA, and Pearson correlation. The average plate waste rate for normal diet and soft diet were 30.3% and 49.6%. More plate waste amount occurred on female patients'diet than male patients'diets regardless of the kind of diet. The plate waste percentage of male patients were higher than those of female on normal diet. On soft diet, patients who hospitalized in surgery or pediatrics department were higher than in other wards. Plate waste of normal diet and amount were correlated positively, but wastage and preference were correlated negatively Negative correlation was between taste and plate waste, and between temperature and plate waste, too. On the other hand, plate waste caused the deficiency of some nutrients such as Ca, Fe, Vit. B$_2$and a great monetary loss.

  • This study was performed to investigate the effect of Gastrodia elata powder on the quality characteristics of Jochung with barley malt. Grain syrups with 0, 2.5, 5, 7.5, and 10% Gastrodia elata powder were produced. The pH value decreased with higher volume of Gastrodia elata powder and showed a significant difference between the samples (p<0.05). Total polyphenol content was 77.45~129.25 mg/100 g, and DPPH radical scavenging ability was $36.70{\sim}57.09{\mu}mol$. Sensory score of Jochung containing 2.5% Gastrodia elata powder was similar to that of control. Jochung containing less than 7.5% Gastrodia elata powder gave the highest scores in terms of quality characteristics and sensory evaluation. The data from different procedures were compared and analyzed by multivariate techniques (correlation matrix, principal component analysis). Correlations between antioxidant activity and the analyzed parameters were found to be statistically significant (p<0.05).

  • Purpose: This study was conducted to understand the factors that affect the acceptance of gluten-free rice pasta samples prepared with added buckwheat, mungbean, and acorn starches, and to compare sensory characteristics of samples with those of 100% semolina pasta. Methods: Descriptive analysis of pasta was conducted by 12 trained panels. Acceptance test was carried out by 40 consumers using 7-point hedonic scale. Collected data was statistically analyzed by principal component analysis, and partial least squares regression analysis. Results: Quantitative descriptive analysis showed that increasing amount of buckwheat, mungbean, and acorn starches resulted in significant improvement in gluten-free rice pasta properties, especially texture, hardness, chewiness, roughness, and al dente with increasing amount of sample starches, and decreased adhesiveness. In acceptance test, appearance and texture of gluten-free rice pasta with mungbean starch were preferred than pasta made with 100% rice. Flavor and taste was preferred in pasta with buckwheat starch than other pasta samples. Rice pasta with 30% buckwheat starch showed the highest score in overall acceptance among rice samples. Conclusion: This study suggested that adding mungbean starch could improve texture of gluten-free pasta, and adding buckwheat starch would improve taste and flavor of gluten-free rice pasta.

  • The aim of this research was to determine the relationship between quality of puffer fish and soak time in maturing water. This research used the cutting cranial nerve method, which is called the MSK method. The data was analyzed using the SPSS program. Based on salinity analysis result, both moisture content and pH were measured after 20 min of soaking. As the salinity of the maturing water increased, the moisture content initially decreased then increased once the salinity was greater than 3%. However, the concentration of the maturing water did not influence the pH level. The texture properties were measured to assess the effect of soak time in the maturing water. Hardness of the sample was highest (3.99) at 20 min, and cohesiveness also showed a maximum value (0.26) at 20 min. Gumminess and chewiness were highest 1.04 and 4.09, respectively, when the fish was matured for 20 min. Sensory properties were evaluated, and springiness, umami flavor, texture, and overall preference were highest at 20 min of soak time. The results showed that maturing the puffer fish for 20 min provided the best quality of texture and sensory characteristics for the fish.

  • The purpose of this study was to investigate the effects of basil on the quality characteristics of tomato sauce, which is used widely in Western cuisine. The highest pH of 4.29 was observed in the tomato sauce with 4% fresh basil added, while the tomato sauce with 0% fresh basil exhibited the lowest pH of 4.20. The pH of the tomato sauce gradually increased with the addition of fresh basil. The analysis of color differences in the tomato sauce indicated that redness(avalue) decreased with the addition of basil;, whereas consistency and spreadability increased with the increasing amounts of the fresh basil. The sensory evaluation was performed with scoring tests for color, flavor, taste, after taste, viscosity, and overall acceptability by 15 professional panelsists. The tomato sauce with 2% basil showed the best score in the sensory evaluation, except for vicosity. From the above results, the data suggest that an addition of 2% fresh basil to tomato sauce is recommended for commercial use.

  • A linear correlation was found by stepwise multiple regression analysis between the sensory score of barley bran sauce aroma and the absolute gas chromatogram (GC) data transformed with square root. In spite of highly significant relationship between the quantity of the peak and the sensory score, it is difficult to estimate the aroma quality of barley bran sauce samples on the basis of only one peak. Peak 29 (methyl 9,12,15-octadecatrienoate) contributed most to the aroma of barley bran sauce. This was followed by 27 (methyl 9,12-octadecadienoate), 28 (ethyl 9,12-octadecadienoate), 12 (phenyl acetaldehyde), and 9 (methyl furfural) in terms of absolute value. When it was calculated using absolute value transformed by square root, peak 28 (ethyl 9,12-octadecadienoate) made the highest contribution to the aroma of barley bran sauce of among the peaks. It was followed by 31 (9,12-octadecadienoic acid), 27 (methyl 9,12-octadecadienoate), 12 (phenyl acetaldehyde), and 29 (methyl 9,12,15-octadecatrienoate).
