  • Quality characteristics and antioxidant activity of spirulina with added tofu were investigated in the presence of different coagulants ($CaSO_4$, $MgCl_2$, Glucono delta lactone (GDL), vinegar). The yield of the spirulina tofu was the highest when coagulated with GDL. The pH of spirulina tofu with $MgCl_2$ was the highest compared to those of other coagulants. The tumidity of spirulina tofu was the highest with $MgCl_2$. In the color analysis of spirulina tofu, the L (lightness) value was the highest with $CaSO_4$, whereas a (redness) value was the highest with $MgCl_2$. C-phycocyanin contents were the highest with the $CaSO_4$. Phycoerythrin of spirulina tofu for vinegar was 0.194 mg/mL, and GDL content was 0.214 mg/mL. Additionally, the antioxidant activity of spirulina tofu was the highest with $MgCl_2$ $IC_{50}$ values of the DPPH radical scavenging activity of spirulina tofu with $MgCl_2$ was 89.2 mg/g, GDL 93.5 mg/mL, $CaSO_4$ 116.7 mg/mL, and vinegar 118.0 mg/mL. The texture analyses (TPA) results showed that hardness was in the order of vinegar>$MgCl_2$>GDL>$CaSO_4$. For the overall acceptability of the preference test, the spirulina tofu that was made using $MgCl_2$ coagulant had the highest score. Based on these results, it is suggested that $MgCl_2$ is the proper coagulant for the preparation of spirulina with added tofu.

  • Contract Managed foodservice has been expanded rapidly in university foodservice operations. The purposes of this study were to examine customers and administrators' preference concerning operation format, the decision making components for operation format, and administrators' attitudes concerning contract managed and self-operated foodservice. Two types of questionnaires were developed and implemented. Customer and administrator's questionnaires were distributed to 900 university students and 27 administrators respectively, and 831 customers and 24 administrators were responded with a response rate of 92.3% and 88.8% respectively. Statistical data analysis was completed using the SPSS programs for descriptive analysis, $x^2$-test, ANOVA, and T-test. The results of this study can be summarized as follows 1. In deciding foodservice operation format, the components customers considered were the ability to provide variety of meal items, aesthetic and safe food(62.6%), the ability to provide a food with competetive low price(22.1%), and the ability to provide adequate service and nutrition information. On the contrary, the components administrators considered were the ability to provide variety of meal items, aesthetic and safe food(66.7%), the ability to relieve administrators of managerial burden of the foodservice operation(12.5%), and the ability to invest facility(8.3%). 2. The average score of attitude on contracted and self-operated management activities were 3.41, 3.10 respectively. University administrators evaluated that contractors performed financial management activities more effectively. 3. University administrators with contracted or self-operated foodservice favored their own current operation format.

  • To improve the sensory acceptability of Kochujang with added Meju powder, Kochujang was prepared with added raw soy powder and roasted soy powder were added instead of Meju powder. These Kochujang were fermented for 45 days at $25{\pm}3^{\circ}C$ and examined for changes in their physicochemical properties and sensory characteristics. Results were as follows. In the moisture content and acidity of Kochujang, the group with added Meju powder was the highest. There were no significant differences in the lightness (L value), although the group with added with Meju powder and raw soy powder were decreased in lightness over days of storage. For redness (a value), the group with added raw soy powder was the highest, and the group with added raw soy powder was decreased with increasing storage days. For yellowness (b value), the group with added roasted soy powder was the highest, and there was no significant difference over storage days. The reducing sugar content of Kochjang to which roasted soy powder was added was the highest, and the amino-nitrogen contents of Kochjang to which Meju powder was added was the highest In sensory evaluation, the Kochjang with added roasted soy powder had the best score in taste and overall acceptability. Therefore, these results suggest that roasted soy powder can be applied to Kochjang for enhanced sensory preference.

  • Purpose: To evaluate the effects of low-dose intravenous N-acetylcysteine on the prevention of contrast-induced nephropathy (CIN) in patients undergoing computed tomography (CT). Methods: All patients presenting to our emergency department and undergoing CT with intravenous contrast media between August 2014 and April 2016 were retrospectively enrolled. We included hospitalized patients with renal dysfunction [estimated glomerular filtration rate (GFR) between 30 and $89mL/min/1.73m^2$]. A 600-mg injection of N-acetylcysteine was given to patients once before and once immediately after CT, depending on the preference of physician. The primary outcome was CIN defined as an increase in creatinine level of ${\geq}25%$ or ${\geq}0.5mg/dL$ from the baseline within 48 to 72 hours after CT. A trained person blindly reviewed all medical records. Results: Of the 1903 admitted patients, CIN occurred in 9.8% of patients who received 1200 mg intravenous N-acetylcysteine (24/244) and 6.8% of patients who did not (113/1659, p=0.090). In a multivariable regression analysis, N-acetylcystine was not relevant to the prevention of CIN (odds ratio=1.42 [95% CI, 0.90-2.26]). Even in the stratified analysis using the propensity score matching, N-acetylcysteine was irrelevant (GFR 30-59: odds ratio=1.06 [95% CI, 0.43-2.60]; GFR 60-89: odds ratio=1.76 [95% CI, 0.75-4.14]). After adjustment, crystalloids were significantly associated with the reduction in CIN compared with dextrose water (odds ratio=0.60 [95% CI, 0.37-0.97]). Conclusion: No effect was found when low-dose intravenous N-acetylcysteine was used to prevent CIN. However, there seems to be an association between crystalloids and reduction in CIN.

  • This study was conducted to evaluate the microbial (Total aerobic count, Coliform, Coagulase positive Staphylococci, Salmonella, Yeast/Mold, Escherichia coli, Bacillus cereus), Hunter'color values ($L^*$, $a^*$, $b^*$) and organoleptic quality of freeze-dried Miyeokguk, Korean seaweed soup in space food. Bacillus cereus was 1 log level while not detected in the sample irradiated at 10 kGy. Hunter's color values of the samples irradiated less than 10 kGy was not significantly different (p>0.05). The sensory evaluation result showed that the preference scores in all the sensory properties decreased when it was irradiated over 10 kGy, but sensory score of less than 10 kGy samples was similar in all terms. Therefore, it was considered that gamma irradiation at 10 kGy was enough to sterilize the freeze-dried Miyeokguk without deterioration of sensory quality.

  • 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.
