  • This study was conducted to develope a new type of ready-to-eat smoked Sebastes schlegeli product with high acceptability and extended shelf-life. A Sebastes schlegeli was salted at 4% salt concentration for 6 hr at $4^{\circ}C$. The cold smoking conditions for the salted Sebastes schlegeli consisted of drying for 2 hr at $22{\sim}24^{\circ}C$ followed by smoking for 2 hr at $22{\sim}24^{\circ}C$. The warm smoking conditions for the salted Sebastes schlegeli consisted of drying for 2 hr at $22{\sim}24^{\circ}C$, smoking for 2 hr at $22{\sim}24^{\circ}C$, and smoking again for 30 min at $47{\sim}50^{\circ}C$. The rancidity of the smoked Sebastes schlegeli did not change after 1 year storage at $-20^{\circ}C$ by monitoring the iodine value, peroxide value, and acid value. The number of viable cells in the cold and warm smoked samples were counted as $7.4{\times}10^5$ and $6.2{times}10^5$ CFU/g, respectively. Viable cells were not detected after 1 year of storage at $-20^{\circ}C$. The sensory evaluations of the processed Sebastes schlegeli showed that elastic texture increased with smoking as compared to with salting. There were no significant differences between cold and warm smoking in terms of sweetness, elastic texture, color, and smoke flavor. However, for overall acceptability, preference were in the oder of cold smoked, warm smoked, and salted.

  • A study on the seafood consumption was conducted from 1902 adolescent students (1110 boys and 792 girls) attending middle or high school to assess the attitude and degree of satisfaction for seafood being served in the school lunch program and ultimately to promote greater seafood consumption. A self-administered questionnaire was used to record the results. The results were as follows: Sixty percent of the respondents appeared to like or not to be reluctant to seafood. The main reasons for favoring seafood were its nutritious effect and taste. On the other hand, the reason for disliking seafood was due to its peculiar smell. In terms of cooking methods, the subjects preferred raw, fried, and grilled seafdod, whereas they disliked salt-fermented, seasoned and stewed dishes. The highly preferred seafood were crab, shrimp, tuna and squid. Only 6.6% of middle school students (MS) and 3.7% of high school students (HS) liked the seafood served in school lunch program, whereas the others responded 'so so'or disliked it. The reasons for disliking seafood being served in school lunch program were poor taste (14.7% of MS, 23.5% of HS), lack of freshness(6.3% of MS, 13.9% of HS) and unattractable cooking methods(3.4% of MS, 11.1% of HS). To promote seafood consumption in school lunch program, subjects anticipated the taste improvement (37.7% of MS, 48.5% of HS), use of a variety of seafood (19.8% of MS, 24.0% of HS) and cooking methods(12.6% of MS, 22.4% of HS). Above results suggested that further efforts are needed to provide preferred cooking methods and seafood items as a way of increasing seafood acceptability.

  • Back-pyun is a kind of rice cake made by steaming rice flour added sugar, water and salt and garnished with shredded chestnuts, dates, mushrooms and pinenuts. The Back-pyun has been widely used in Korean celebrations. This study aimed to compare and determine the effects on sensory characteristics and texture of Back-pyun 1) when the proportion of glutinous rice, added i.1 making Back-pyun, is 0%, 5%, 10%, 15%, 20%, 25% and 30% 2) then it reheated after storage for 0,24, 48 and 72 hours. Evaluation was conducted through sensory evaluation and objective evaluation. The results are as follows : 1. In sensory evaluation, color of Back-pyun turned yellow as the addition level of glutinous rice increased and then by reheating after storage for 24, 48 and 73 hours. Coarseness was not significantly different as the addition level of glutinous rice increased before storage. But Back-pyun reheated after storage for 24,48 and 72 hours were significantly different by the addition level of glutinous rice. Softness, dryness and crumblyness tended to decrease as the addition level of glutinous rice increased and by reheating after storage for 24, 48 and 72 hours. The most favorite tendency on the appearance was at the addition level of glutinous rice of 5%. Texture and overall preference were better at the addition level from 10% to 20% than any other levels. 2. Rheometer measurement indicated that compression force, gumminess ana chewiness tended to increase as the addition level of glutinous rice increased and decrease by the storage conditions. But work ratio and recovered height did not have much effect the addition level of glutinous rice and the storage conditions. Compression force of Back-pyun (not reheated) tended to increase by the storage time and the addition level of glutious rice. Especially it showed remakably increasing tendency during 24 hours storage (at $4^{\circ}C$) 3. Moisture content tended to increase by the addition level of glutinous rice and decrease by the storage time. But moisture content of Back-pyun reheated after storage for 24 hours stowed the increasing tendency. 4. Softness of Back-pyun had significant relationship with compression force and work ratio. Dryness and crumblyness had significant relationship with work ratio. Therefore compression force and work ratio represented the texture of Back-pyun.

  • The purpose of this study, as a part of developing a new french dressing, was to present the best conditions to make improved kiwi dressing, suitable for the tastes of modern people, the processing and cooking methods of different ratios of green kiwi and gold kiwi have been sought to develop a new type of dressing, then its antioxidant have been defined, and used for producing kiwi dressing. Each 150g of different Kiwi purees, made based on the most preferable combinations from the pre-test were used for kiwi dressing, and thereafter its quality characteristics, and physical properties were investigated, as well as a sensory test was conducted. The highest viscosity of kiwi dressing was test sample GD2, and in general that of combining both types of kiwis were higher than that of either single kiwi. The sugar content was decreased by changing the Gold kiwi portion(p<0.05). The chromaticity in general increased with increases in the Gold kiwi portion, and a-value(brightness) and b-value(redness) of sample GD1 were the highest by -2.75 and 17.50(p<0.05). From the acceptability test, the highest overall acceptability was the dressing sample combining Gold kiwi and Green kiwi at a ratio of 1:1. Based on the study results, it is expected that the dressing, made of kiwi puree, mixing Green kiwi and Gold kiwi by 1:1 ratio, and adding 130g of edible oil, 50g of onion, 40g of sugar, and 5g of salt, would improve the quality and overall acceptability of the dressing.

  • The physicochemical and microbial characteristics of pickled cucumber prepared with dry salting method, which has been used for industry, were investigated. Salting and storage conditions were HSHT $(30\%,\;25^{\circ}C)$, MSMT $(21\%,\;15^{\circ}C)$, MSLT $(21\%,\;0^{\circ}C)$, LSMT $(15\%,\;15^{\circ}C)$ and LSLT $(15\%,\;0^{\circ}C)$. Acidity was lower, and pH was higher in higher salt concentration as well as lower temperature groups. At the storage of 165 days, acidity and pH reached to $0.21\%$ and 4, respectively in MSLT and HSHT, of which conditions fermentation was retarded, compared to the other groups. During storage of pickled cucumber, greenness (-a) of Hunter color system showed the highest in MSLT ranged from -10.70 to -8.08, while in LSMT, the lowest to 1.17. Total microbial and lactic acid bacteria number in HTST and MSLT were the lowest than in other groups, while tile highest in LSMT. Yeast was not detected in HSHT and MSLT after 36 days of storage, while higher in LSMT Texture profile analysis exhibited that fracturability (2,318 g and 2,318 g) and hardness (849 g and 702 g) were highest in HSHT and MSLT, compared to the other groups. Scores of over-all preference for MSLT and LSLT were higher with 8.8 and 7.6, respectively, compared to the other products (p<0.05). Based on these results, lower saltiness and lower storage temperature condition was better for pickled cucumber preparation in industry.

  • Objectives: The purpose of this study was to compare the diabetic management indicators between agriculture, forestry, and fishery workers (AFF) and other occupational adults (non-AFF) in community-dwelling diabetes. Methods: The study population consisted of 22,127 diabetic population ${\geq}19years$ who participated in the 2015 Community Health Survey. Chi-square test and logistic regression analysis was used to compare the diabetic management indicators between AFF and non-AFF. Socioeconomic characteristics such as age, gender, education level, monthly household income, National Basic Livelihood Security status, and marital status was sequentially adjusted. Results: Among total diabetic population, 3,712 people (16.8%) was AFF and 18,415 people (83.2%) was non-AFF. The fully-adjusted odds ratio [OR] (95% confidence interval [CI]) of current non-medical treatment (0.72, 0.66-0.79), measurement of hemoglobin A1c (0.61, 0.55-0.67), screening for diabetic retinopathy (0.76, 0.70-0.83), screening for diabetic nephropathy (0.75, 0.70-0.81), non-alcoholic or moderate drinking (0.70, 0.64-0.78), nutrition label reading (0.83, 0.71-0.98), low salt preference (0.85, 0.78-0.93), dental examination (0.60, 0.54-0.66), scaling experience (0.84, 0.77-0.93), regular toothbrushing (0.66, 0.58-0.76), and diabetes management education (0.84, 0.77-0.92) was significantly lower in AFF compared to non-AFF. In contrast, the fully-adjusted OR (95% CI) of AFF's low stress level (1.39, 1.26-1.52) and adequate sleep duration (1.22, 1.13-1.32) was significantly higher than non-AFF, which are better indicators of diabetic management in AFF. Conclusions: Overall, the level of diabetes management of AFF was not as good as that of non-AFF. In order to improve the level of diabetes management of AFF, a delicate diabetes intervention strategy considering the occupational characteristics of AFF will be needed.

  • In this study, Kimchi, soup and stew samples were collected from May to June, 2007, in the Jeonju area, and their salinity levels were analyzed. In addition, housewives were surveyed via questionnaire to assess food behaviors and consumption patterns. The average salinity of the Kimchi samples was $2.0{\pm}0.5%$. The average salinity of the soup/stew samples was $1.0{\pm}0.3%$ in the broth portion and $0.8{\pm}0.3%$ in the homogenized mixture of both broth and solids. The average salinity of all types of soup was $0.9{\pm}0.3%$, and that for stews was $1.1{\pm}0.3%;$ the average salinity of the stew was significantly higher than that of the soup (p<0.001). Beanpaste soup had a significantly higher average salinity $(1.0{\pm}0.3%)$ than clear soup $(0.8{\pm}0.3%)$ (p<0.05). The Food behavior scores of the respondents, with regard to sodium intake and salty taste preference, showed significant positive correlations to the salinity of the soup and stew samples (p<0.01). The consumption patterns of the Kimchi and soup/stews were also analyzed to determine whether there was a relationship to the saltiness of the food samples. The respondents were divided into two groups for each food category: Kimchi groups of below 2.0% salinity and above 2.1% salinity, soup/stew groups of below 0.8% salinity and above 0.9% salinity. The below 0.8% salinity soup/stew group used salt or soy sauce in meals significantly less frequently (p<0.01) than the above 0.9% salinity group. The lower salinity Kimchi and soup/stew groups gave significantly higher scores regarding answers that their Kimchi was 'bland' (p<0.05). The types of frequently consumed Kimchi were determined as Korean cabbage, Welsh, wild greens, radish, KKak Du Ki, and Yol Mu Kimchi. When compared to the above 2.1% salinity Kimchi group, the below 2.0% salinity Kimchi group gave higher scores regarding answers that they consumed 'more than half the broth in the bowel' and also gave significantly higher (p<0.01) scores in answering that they consumed only the solid ingredients, leaving the broth.
