  • This study investigated the changes in the physicochemical characteristics and sensory evaluation of Aster scaber by blanching treatment time. Aster scaber was blanched with $100^{\circ}C$ hot water for 1~5 min. At $100^{\circ}C$ blanching, the total polyphenol contents of the sample blanched for 1~5 min ranged from 7.57 to 6.45% while the sample blanched for 5 min showed a severe loss of phenolic compounds. The sample blanched $at 100^{\circ}C$ for 5 min had the lowest $L^*$ and $b^*$ values (24.96 and 16.14, respectively) and the highest $a^*$ value (-10.39) among all the samples. With regard to the texture profile, the sample blanched at $100^{\circ}C$ for 5 min was the highest in texture. Significant reductions in the texture, color, and total phenol content were observed after blanching. In the sensory evaluation, the Aster scaber sample blanched with hot water at $100^{\circ}C$ for 2 min showed the highest color, appearance, and flavor while the sample heated with boiling water for 3 min had the highest sensory score in terms of texture and overall acceptability. In conclusion, the 3 min blanching of Aster scaber yielded the best sensory quality.

  • This study aimed for exploring the best recipe of Seosokbyung with different ingredient ratios of glutinous millet flour, sugar, and water added to rice flour. The most desirable recipe was determined by sensory evaluation and mechanical test for measuring texture, moisture content and colorimetry. The best score for each sensory item was obtained in the following condition: Color-245g(70%) of glutinous millet flour, 50g of sugar with 10$m\ell$ of water in 105g of rice flour. Flavor-l75g(50%) of glutinous millet flour with a 80$m\ell$of honey in 175g of rice flour. Graininess and Moistness-245g(70%) of glutinous millet flour with 70$m\ell$ of honey in 105g of rice flour. Chewiness-2I0g(60%) of glutinous millet flour, 60g of sugar with 20$m\ell$ of water in 140g of rice flour. Sweetness-l75g (50%) of glutinous millet flour 7g of sugar with 25$m\ell$ of water in 175g of rice flour. As a result of mechanical examination, the best score for springiness, cohesiveness, chewiness, gumminess, adhesiveness was obtained in the recipe of 175g (50%) of glutinous millet flour with 80$m\ell$ of sugar in 175g of rice flour, and that for hardness in the one of 245g (70%) of glutinous millet flour with 70$m\ell$ of honey in rice flour As the less amount of glutinous millet flour was added, the scores for springiness, cohesiveness, chewiness, gumminess and adhesiveness were increased, and the addition of honey gave higher scores than sugar or oligosaccharide(P<0.05) The best recipe of Seosokbyung was 140g of rice flour, 2 l0g of glutinous millet flour, 60g of sugar, 20$m\ell$ of water and 3.5g of salt. The moisture contents of rice flour and glutinous millet flour were 31.6% and 13.3%, respectively. The content of moisture in the best recipe of the Seosokbyung is approximately 36.101%. The moisture content higher than 36% gave better sensory scores in chewiness and moistness. As a result of colorimetry, the most bright ‘L’value(Lightness) was obtained from 175g of rice flour mixed with 175g (50%) of glutinous millet flour, 70g of sugar and 25$m\ell$ of water. The highest ‘a’ value(Redness) was gained from 175g of rice flour mixed with 175g (50%) of glutinous millet flour and 80$m\ell$ of honey. The best ‘b’ value(Yellowness) was obtained from 140g of rice flour, 210g (60% of rice flour) of glutinous millet flour, 60g of sugar and 20$m\ell$ of water.

  • This study was conducted to investigate the effect of quality grade on the physicochemical and sensory properties of Hanwoo beef on the basis of four quality grades (grade $1^{{+}{+}}$, $1^{+}$, 1, and 2). Significantly decreased levels of myoglobin content (from 12.73 mg/g to 7.90 mg/g) and Warner-Bratzler shear force (WBs) (from 28.01 kg to 14.03 kg) were found with reduction in quality grade (p<0.05). In contrast, increasing quality grade correlated with significant increase in crude fat contents (from 8.18% to 19.55%). Crude fat contents showed a negative correlation with moisture content (r=-0.966), myoglobin content (r=-0.998), and WBs (r=-0.969). In sensory evaluation experiments it was revealed that quality grades were associated with significantly altered (all p<0.05) flavor, taste, juiciness, tenderness, and overall acceptability. Moisture contents showed negative correlation with taste (r=-0.969) and overall acceptability (r=-0.988). Crude fat contents showed significant correlation with taste (r=0.971), tenderness (r=0.983) and overall acceptability (r=0.968). WBs showed negative correlation with taste (r=-0.957) and overall acceptability (-0.978). The marbling score of fresh meat showed significant correlation with taste (r=0.958), juiciness (r=0.953), and overall acceptance of cooked meat. These results could be used as a fundamental dataset to evaluate the effect of quality grade on the physicochemical and sensory characteristics of Hanwoo beef.

  • This study focused on the relationships among leaf and smoke components and sensory properties following tobacco leaf blending. A completely randomized experimental design was used to evaluate components of leaf and smoke and sensory properties for sample cigarettes with four mixtures of flue cured and burley tobacco (40:60, 60:40, 80:20 and 100:0). Eleven leaf components, six smoke components, and eight sensory properties of smoking taste were analyzed. A sensory evaluation method known as quantitative descriptive analysis was used to evaluate perceptual strength on a fifteen score scale. Raw data from ten trained panelists were obtained and statistically analyzed. Based on the MANOVA, clustering analysis, correlation matrix and partial least square (PLS) method were applied to find out which smoke component most affected sensory properties. The PLS method was used to remove the influence between explanatory variables in the leaf, smoke components derived from the results. High correlations (p<0.0l) were found among ten specific leaf and smoke components and sensory attributes. Total nitrogen, ammonia, total volatile base, and nitrate in the leaf were significantly correlated (p<0.05) with impact, bitterness, tobacco taste, irritation, smoke volume, and smoke pungency. From the results of PLS analysis, influence variables are used to explain about the correlation. In terms of bitterness, with only two explanatory variables, Leaf $NO_3$ and Leaf crude fiber were enough for guessing their correlation. In the distance weighted least square fitting analysis, carbon monoxide highly influenced bitterness, hay like taste, and smoke volume.

  • The relationship between the gas chromatographic (GC) patterns of sauce made of barley bran and ranked order in sensory analysis was investigated by multiple regression analysis (MRA). Most of the 42 barley bran sauce samples comprised about 34 peaks, in which the content of 9, 12-octadecanoic acid methyl ester was the highest, followed by those of 2-furanmethanol and 2-furancarboxaldehyde. It is difficult to estimate the aroma quality of barley bran sauce samples on the basis of only one peak. The 34 aroma compounds of the 42 samples were analyzed by an MRA model featuring six transformations. The most precise fit was calculated from the absolute value transformed with the root square of each peak, and the multiple determination coefficient showed that 91.6% of the variation in the sensory score could be explained on the basis of GC data.

  • To develop a new type of surimi with added citrus fruits, we examined the colors, textural properties and sensory evaluations of surimi after production. In the folding test, all samples had good flexibility, which suggested that addition of citrus fruits did not influence the flexibility of surimi. The pH in surimi samples was, in increasing order: lemon(Citrus limon), citron(Citrus junos), tangerine(Citrus unshiu), cumquet(Fortunella japonica var. margarita), and control. The pHs of each citrus fruits and the surimi with added citrus fruits were similar. Lightness increased in the following order: lemon, cumquet, control, citron, and tangerine surimi. Redness was high in the following order: tangerine, cumquet, control, citron, and lemon surimi. Yellowness increased in the following order: tangerine, cumquet, citron, lemon, and control surimi. There were no significant differences between lemon and control surimi. The hardness of surimi was highest in lemon, followed by citron, tangerine, cumquet, and control surimi. Although control surimi was the lowest, there were no significant differences among the samples. In terms of springness, it increased in the following order: tangerine, citron, control, lemon, and cumquet, but there were no significant differences among the samples. In sensory evaluation, overall acceptability decreased in the following order: cumquet, tangerine, control, citron, and lemon. Surimi containing cumquet got the best score in colors, textural properties, and taste except flavor. All samples got positive results in sensory ova luations, except for textural properties and taste of lemon and citron. Here, we confirm that surimi can be made with added citrus fruits, although we should examine in detail the quantities of added lemon and citron in a later study.
