  • Water activity of sausage added Umbelliferaeceae wild plants powder was decreased as storage time was prolonged and all samples were lower than those of the control. During the storage period, pH values of all samples were decreased. Cooking loss and storage loss was decreased as storage time was prolonged and showed differential from added sample. L, a, b values had a tendency to decrease, during the storage period. As the percentage of the wild plants powder in sausage, L, a values were decreased and b value was increased. Total plate counts of bacteria were increased as storage time was prolonged and wild plants powder added sausages were lower than control. Coriander 3.0% added sausage was the lowest total plate counts of bacteria, 1.3$\times$10$^{6}$ at four week'storage. As the percentage of wild plants powder in sausage was increased, total plate counts of bacteria decreased. Springiness, cohesiveness, chewiness, gumminess and hardness value of all sample were increased or decreased as storage time was longer. But they did not showed greatest various with storage time as well as additives. The sensory score of wild plants powder 0.5% added sausage were the highest, but wild plants powder 3.0% added sausage were the lowest. All the sensory score of coriander added sausage were high. The sensory score of all sample were decreased as storage time was prolonged. In wild plants powder 3.0% added sausage, the relationship between color, flavor, chewiness, wetness, taste and overall of sensory evaluation and all item of the textural characteristic showed huh correlation score.

  • This study was conducted to evaluated the sensory properties of Miyukgook, Korean seaweed soup, with gamma-irradiated Undaria pinnadifida for enhancing the storage of the harvested seaweed. The harvested seaweed was irradiated at the doses of 1, 3, 5, and 10 kGy. The Miyukgook was made by following the general recipe. The values of pH and acidity of the Miyukgook were not changed by the irradiation of harvested Undaria. The sensory evaluation result showed that the preference scores in all the sensory properties was a little decreased when it was irradiated, but sensory score of less than 5 kGy samples was similar in all terms. Therefore, it was considered that gamma irradiation with less than 5 kGy was effective for improvement of the storage stability of U. pinnatifida without the changes in the sensory of its major cooked food, Miyukgook.

  • The Microbiological, chemical and sensory analyses were carried to evaluate the quality of commercial salted and fermented seafoods and to establish a standardization. The results showed that amino nitrogen(AN) and volatile basic nitrogen(VBN) contents were appropriate in evaluating the quality of shrimp jeotkal. In the range of $150{\sim}300\;mg%\;and\;25{\sim}70\;mg%$, AN and VBN contents were highly correlated to sensory scores, respectively. In the case of squid jeotkal, pH and VBN contents were appropriate to evaluate quality. The coefficients of the correlation between pH and sensory evaluation was 0.84 and the sensory acceptability was high and above pH 6.0. In addition, the coefficients of the correlation between VBN contents and sensory evaluation was 0.95, and the sensory acceptability was high but below 30 mg%. In the case of shell-fish jeotkal, the coefficient of the correlation between VBN content and sensory evaluation was 0.94, and sensory acceptability was high but below 40 mg%.

  • In this study, we analyzed 24 pieces ($4{\times}3{\times}2$) of pork jerky produced using raw meat and we then randomly assigned the hind leg meat to a treatment group. In addition, the effects of storage according to aerobic plate counts and sensory evaluation on pork jerky were examined. Form the results, We found that volatile basic nitrogen (VBN) content and aerobic plate counts of pork jerky gradually increased with increased storage time, ; moreover, there was a significant difference between the treatment groups and the control group (p<0.01). However, the counts did not increase as significantly in the ginseng powder group (B), as compared to the ginger powder group (A) (p<0.05). The sensory evaluation of pork jerky peaked during the second week of storage in all treatment groups, after which these characteristics gradually decreased (p<0.05). In addition, these characteristics were generally higher in the control group, compared to the treatment groups. When comparing the ginseng powder addition group (B) and ginger powder-addition group (A), only color was significantly higher in the ginger powder group. Based on this study as well as previous studies, storage of pork jerky significantly affects the sensory evaluation of raw pork. Ginger powder may have a more beneficial effect than other treatments on the sensory evaluation. Additionally, in all treatment groups, sensory characteristics were significantly higher in the ginger treated groups than in those of the ginseng-treated groups.

  • The objective of this study is to analyze the images of basic bodice apparel displayed on the PC monitor connected to digital camera, and to suggest a more efficient alternative method that enables the expert judge to evaluate the subject both traditional method and displayed images on the computer. Appearance evaluation has traditionally been assessed using subjective method dependent upon expertjudges' senses with the naked eye after direct observation of a living model. This research faces the new challenge focusing on the sensory evaluation of appearance for basic apparel patterns, which can overcome the space and time limitations of the traditional feet methods. A total fifteen basic bodice garment (3 types of $pattern\;{\times}\;5$ subject) were constructed with same fabrics. The appearance evaluation items consist of lg questions of upper torso. The image takes font, back and side view of the dressed subject with three different situations. Data was analyzed using percentiles, standard deviation T-test and ANOVA. Taken together, the present result of appearance evaluation through digital camera image shows that there is a significant difference ($p{\leq}.001$) in the response to the placement of the neckline, the waist & shoulder dart, the general ease of the bust & waist area, the side seam, the perpendicular of the waist hem and general acceptability between the above three different situations; the image in the condition of greenish yellow background with front light showed the highest score through all questions. These results depend on the kind of background colors with the light.

  • To confirm the influence of modified starch on frozen storage stability, the microstructure and sensory characteristics of fish cakes, called Eomuk in Korea, by using seven varieties of starch, including native starch (NS), physically treated corn starch (MS) and modified starch [treatment with acetate (SA-1, SA-2 and SA-3), hydroxypropyl (HS), and acetylated distarch adipate (ADA)] were evaluated. Scanning electron microscopy (SEM) photographs showed fish cakes with NS had a finer and denser network structure than those made with modified starches. During frozen storage, fish cakes with HS and ADA exhibited a stable structure, as evaluated by porosity and rough surface. The results of the sensory evaluation showed that modified starch, including HS, SA-2 and ADA, increased the taste and firmness of the fish cakes, while NS, MS and the modified starch SA-3 resulted a decrease in the sensory properties during storage. Therefore, HS, SA-2 and ADA are suitable additives to improve the sensory quality of frozen fish cakes.

  • Pork quality is determined by several attributes, among which odor and taste are the utmost significant. Therefore, this study was aimed to assess the effects of boar odor hormone concentration on the quality traits and sensory acceptability of pork. A total twenty-six (26) non-castrated 3-way crossbred (Landrace × Yorkshire × Duroc) pigs were selected with an average body weight (ABW) 115.6 kg before to slaughter. The three treatment groups (low, medium and high) were divided according to the androstenone concentration. In experiment 1, for meat quality traits carcass was selected based on androstenone concentration: low (LC, 0.64-0.69 ㎍/g, n = 9), medium (MC, 0.70-0.99 ㎍/g, n = 7) and high (HC, 1.00-1.69 ㎍/g, n = 10). In experiment 2, for sensory evaluation carcasses were also selected based on the abovementioned conditions. Results revealed that androstenone concentration not effect on proximate components, meat quality traits and fatty acids except palmitoleic acid. Sensory evaluation data showed that boar taint and meat boar taint were significantly increased in a concentration-dependent manner from low to high, whereas, gravy and meat flavor preference were significantly increased in LC group than HC group. In addition, correlation analysis showed that boar taint and meat boar taint were positively, and gravy and meat flavor preference were negatively correlated with boar taint hormones. In essence, our findings indicate that androstenone concentration had no effect on meat qualities, but a high concentration of androstenone had a negative effect on the sensory characteristics in uncastrated pigs.
