This research was performed to determine the quality characteristics of cookies made from flour added with 0, 1, 3, and 5% sea mustard (Undaria pinnatifida Suringer) powder. The quality characteristics of the cookies, including pH and density of the dough, moisture content, spread factor, loss rate, leavening rate, color, mineral content, texture properties, and sensory properties, were estimated. The density of the dough, water content, spread factor, loss rate, leavening rate, a and b values of color scale, and mineral content of the cookies significantly increased while those of pH, L value, and hardness decreased with higher content of sea mustard powder. With the exception of flavor, consumer acceptability scores in terms of appearance, taste, texture, and overall preference for cookies made from 3% sea mustard powder significantly ranked the highest. Taken together, the results of this study suggest that addition of 3% sea mustard powder to flour is effective for increasing the consumer acceptability and functionality of cookies.

This study was carried out to investigate the characteristic quality of jeungpyun added Paecilomyces japonica with different fermentation time. The volume of jeungpyun added Paecilomyces japonica was more increased after fermentation. The volume was decreased when the fermentation was progressed. The pH was 5.1 before fermentation and the pH decreased when the fermentation was progressed. Moisture content was more increased as the time of fermentation became longer. Hunter color test, L value and b value appeared the highest after 1st fermentation, and it appeared lesser when the time of fermentation became longer. In measurement of texture, hardness showed the highest value when 90 minutes passed after the 2nd fermentation. Gumminess and brittleness were tend to increase when it have longer fermentation time. In scanning electron microscopic observation, organization of sponges was tend to break down as the fermentation time was longer. Sensory properties showed that color intensity was more strong when second fermentation was progressed, and hardness, toughness, sourness were high when the fermentation time was longer. In conclusion overall acceptability of jeungpyun, 3$0^{\circ}C$, 3 hours after 1st fermentation and 2nd fermentation for 30 minutes, 35$^{\circ}C$ showed the most preference.
Purpose: This study evaluated the effects of personalized nutrition intervention for increasing hospital meal intake by elderly patients with malnutrition. Methods: The subjects were 30 elderly patients with malnutrition who visited a general hospital located in Daegu. An individual nutrition intervention such as change of meal types or special meal service was given to the patients according to nutrition diagnosis related to inadequate intake of hospital meals. Nutritional intake status of the subjects was assessed by analyzing energy intake, protein intake, index of nutritional quality (INQ), nutrient adequacy ratio (NAR) and mean adequacy ratio (MAR). Results: The causes of inadequate intake in the subjects were poor appetite or preference problems (46.7%), symptom-related problems (30.0%) and mastication problems (23.3%). The INQ of protein in the subjects was significantly increased from $0.81{\pm}0.17$ to $1.41{\pm}0.25$ after the nutrition intervention (p < 0.05). The NAR of protein (before $0.50{\pm}0.21$, after $0.58{\pm}0.17$), iron (before $0.72{\pm}0.30$, after $0.84{\pm}0.29$) and vitamin $B_2$ (before $0.31{\pm}0.16$, after $0.37{\pm}0.14$) was also increased after the nutrition intervention (p < 0.05). The MAR of five nutrients, protein, calcium, iron, vitamin A and vitamin $B_2$, was significantly increased by the nutrition intervention (p < 0.05). Conclusion: Personalized nutrition intervention according to nutrition diagnosis related to inadequate intake of hospital meals may improve the intake amount of elderly patients with malnutrition.
To investigate the effects of functional MA films (FMA) masterbatched by zeolite powder treated with 1 N HCl, 0.5 N NaCl solution and anti-fogging agent (NA) compared with control on the freshness extension of 'Fuji' apples during storage at $15^{\circ}C$. Preference, weight loss, total ascorbic acid, sugar content, acidity, change of gas composition in package were measured. After 150 days of storage, the weight loss of control (L) apples was 1%, that of apple in FMA film (NA) was 1.5% after 150 days. Total ascorbic acid content of apples in control (L) after 150 days was 2.09 mg%, those of apple in FMA film (NA) was 2.72 mg%. The titratable acidity of apple in FMA film was higher than that in control, while soluble solids content of apples in FMA film was lower than that in control after 150 days. Ethylene gas adsorbability in control was 192.2 ppm and those in FMA film was 141.4 ppm after 150 days. Overall, apples in FMA film was better than that of control. It was verified that apples packed with LLDPE film (control) lasted about 130days, while those with FMA films lasted about 170 days. Also, FMA films treated with anti-fogging agent few different compare to nontreated film, but commerdity on the display in market was considered higher than that of non-treated anti-fogging agent.
To find the association of perception of health status with lifestyle of different ethnic groups living in north-eastern part of China, a cross-sectional questionnaire survey was done by 10 local health workers for 375 Korean immigrants and 217 Chinese whose age was 30 years old or more. Because Korean immigrants showed higher mortality than Chinese, we expected to find significant lifestyle related with perception of health status which was known to be a predictor of mortality by different ethnic groups. The results were as follows : 1. We found that 59.7% of Yanbian Koreans and 42.9% of Yanbian Chinese felt unhealthy (p=0.000). 2. For Yanbian Koreans, significant variables associated with perception of health status were selected through logistic regression analysis and they were sex; female to male with an OR=2.45 (95% confidence interval[CI] 1.06, 5.64), prevalence of chronic illness with an OR=5.48 (95% CI: 4.62, 15.56), mont of meal; small or moderate to full with an OR=2.67 (95% CI : 1.40, 5.09), preference of spicy food with an OR=1.78 (95% CI : 1.04, 3.04), and less amount intake of vitamin $B_2$, with an OR=2.29 (95% CI : 1.33, 3.93). 3. For Yanbian Chinese, significant variables associated with perception of health status were prevalence of chronic illness with an OR=4.97 (95% CI : 2.11, 11.68), history of taking ginseng with an OR=3.72 (95% CI : 1.33, 10.43), and less intake of vitamin C with an OR=0.18 (95% CI : 0.07, 0.46). In conclusion, sex, presence of chronic illness, dietary habit, and amount of $vitamin-B_1$ intake were associated with perception of health status in Yanbian Koreans. Presence of chronic illness, experience of ginseng intake, and amount of vitamin C intake were associated with perception of health status in Yanbian Chinese. To prove cause-effect relation between perception of health status and lifestyle, further study is needed for these different ethnic groups.
Objective : This study investigated the relationship between diet and lifestyle and Sasang constitution (SC) in acute stroke patients. Methods : From October 2005 to March 2007, 379 acute stroke patients were included. Patients were hospitalized within 14 days after the onset of stroke at DongGuk University International Hospital, Kyungwon University In-cheon Oriental Medical Hospital or Department Cardiovascular and Neurologic Diseases (stroke center), Kyung Hee University Oriental hospital. We assessed the type of SC of acute stroke patients by Questionnaire for Sasang Constitution Classification II (QSCC II). We investigated general characteristics, stroke types, dietary preferences (meat, sea food, fast food, alcohol drinking, coffee and green tea drinking) and lifestyle (smoking, exercise) according to SC. Results : This study showed that out of the total patients, the proportion of So-yang to Tae-eum to So-eumwas equal to 2.6 to 2 to 1. Of note, this study showed a higher proportion in age of So-eum & weight of Tae-eum. The ratio of cerebral hemorrhage to cerebral infarction was 1 to 9. SVO, LAA, SUE are the 3 types of cerebral infarction classified by TOAST; SVO ranked the highest while SUE ranked the lowest in all constitutions. There were no significant differences between So-yang and Tae-eum in the aspect of the preference for meat, but the majority of So-eum displayed high preferences for seafood. In the aspect of alcohol drinking and smoking history, So-yang recorded significantly bigger proportion while So-eum & Tae-eum patients represented a bigger proportion than So-yangin the aspect of no exercise habits. Conclusion : According to the result above, we could observe the general disposition of various characteristic distributions according to SC of acute stroke patients. Also, we could observe a relationship between diet and lifestyle and Sasang constitution (SC) in acute stroke patients. Further studies will be needed to better understand the relationship between diet and lifestyle and Sasang constitution (SC) in acute stroke patients.
The quality and sensory characteristics of kimchi added various levels of rosemary leaf during fermentation at 15$^{\circ}C$ were evaluated. Rosemary leaf amounts were added 0.5g(R0.5%), 1g(R1%), 1.5g(R1.5%) per brined chinese cabbage 100g. The pHs and reducing sugar contents of all experimental groups decreased with increasing the fermentation time, whereas levels of titratible acidity increased. The pHs and reducing sugar contents of experimental groups added rosemary leaf showed higher than control, but titratible acidity of these groups showed lower. Also, the period reached the maximum levels of the log number of lactic acid bacteria counts(cfu/ml) and total viable bacteria counts(cfu/ml) of experimental groups added rosemary leaf were more delayed than control. These results showed that the fermentation of experimental groups added various levels of rosemary leaf were slower than that of control. On the 5th day of fermentation which had most delicious kimchi flavor, the sensory evaluation analyzed by ANOVA followed Duncan's multiple range test showed that sour smell of experimental groups added rosemary leaf was significantly lower, but green flavor and green smell of these groups were significantly higher than control(p<0.05). The most preference among experimental groups was R0.5% and next was control, R1.5%, R1%.
In order to ascertain latitudinal variation of lipid contents and compositions in copepods, we collected warm water copepod species (Euchaeta sp. and Pleuromamma spp.) from four different regions from low (sub-tropical) to mid (temperate) latitudes in the Northwest Pacific Ocean. Total lipid contents of Pleuromamma spp. were about 11 $ug{\cdot}ind^{-1}$ with little latitudinal variation, whereas Euchaeta sp. showed slightly higher lipid content (20 $ug{\cdot}ind^{-1}$) than Pleuromamma spp. with latitudinal gradient (low at subtropic and high at temperate). Wax esters, known as the major storage lipid classes, were found to be the dominant lipid classes (accounting for more than 35% of total lipids) in Euchaeta sp., whereas in Pleuromamma spp., phospholipids, known as cellular membrane components, were the dominant lipid classes. However, the exception was specimens from warm pool region exhibiting dominance in storage of lipids as a form of triacylglycerols. Among fatty acids, polyunsaturated fatty acids (PUFA), especially docosahexaenoic acid (DHA : 22:6(n-3)) (about 35% of total fatty acids), were most abundant in Euchaeta sp., while saturated fatty acids (SAFA), specially hexadecanoic acid (16:0) (about 30% of total fatty acids), were most abundant in Pleuromamma spp.. Among the neutral fraction of lipids, phytol, originated from the side chain of chlorophyll, was found in all samples which generally indicate active copepods feeding on algae. While only trace amounts of short-chain fatty alcohols were found in Pleuromamma spp., significant amounts of fatty alcohols were found in Euchaeta sp.. Particularly, significant amounts of long chain monounsaturated fatty alcohols (20:1 and 22:1), generally found in cold water species, were found in Euchaeta sp. from low latitudes. The latitudinal variation of trophic lipid markers in these copepods could be significantly related with in-situ food availability and species-specific diet preference. The result of this study suggests that the lipid contents and compositions in copepods may not only indicate their nutritional condition and feeding ecology but also provide insight into species-specific living strategies under different environmental conditions (i.e. water temperature, food availability).
In this study, we have developed taste and other functional enhancements of yam chips, from tasteless and flavorless yam slices, through the process of soaking freeze-dried yam in different commercially available juices, including apple, omija (fruit of Maximowiczia typica), grape, wild grape, orange, tomato, red ginseng, and black garlic juice. The analyses of color (brightness, redness and yellowness), pH, brix, acidity, total polyphenol, total flavonoids, total sugar and reducing sugar, DPPH and ABTS scavenging activity, reducing power and nitrite scavenging activity, of the different yam chips showed that the freeze-dried yam slices absorb various components of fruit juices, such as flavonoids, sugars, organic acids and flavors, during the soaking process. These changes resulted in increased taste (both sweet and sour tastes), flavor and antioxidant activity in the yam chips. The soaking time for yam slices in juice is considered to be a crucial factor for the taste and bioactivity of yam chips. In the case of grape juice-yam chips, which had the highest preference among the 8 different chips, the optimum soaking time was noted as 120 seconds. The optimization of the soaking process is necessary for various juices. These results suggest that taste, and other functional enhancements, in yam chips can be developed by juice-soaking and freeze-drying methods.
The purpose of this study was to investigate the properties of tteok prepared from white (Samkwang) and brown rice (Heugseol, Heugjinju). The moisture and crude protein contents of rice were 14.89~17.15% and 4.79~6.81%, respectively. The crude lipid and crude ash contents of rice were 0.48~2.66% and 0.39~1.60%, respectively. The water binding capacity of Heugjinju (141.97%) was higher than those of other rice flours. As the soaking time increased, water absorption ability was in the order of Samkwang > Heugseol > Heugjinju. Using a rapid visco analyser (RVA), the initial pasting temperature of Heugseol was the highest, and the peak viscosities of Heugseol were higher than those of other rice flours. The quality characteristics of Tteokbokki tteok were assessed after its preparation by adding different amounts of Heugseol and Heugjinju (0, 5, 10, and 20%, w/w) content. The textural properties (hardness), of Heugseol and Heugseol measured using a texture analyzer, were greater than those of the control. Sensory preference tests revealed that 10% Heugseol and, 10% Heugjinju had the highest scores in appearance, color, and overall acceptability. The sensory test results revealed that Tteokbokki tteok prepared by addition of 10% added brown rice was the best.
