In 2023, a number of seeds suspected to be discolored black oat seeds on oat farms in Gangjin were observed and examined for fungal infection. The species Alternaria alternata was predominant, accounting for 84% of all fungal infections. The appearance and quality of seeds harvested in 2022 were compared with seeds harvested in 2023 from the same field. The lightness value was lower in the seeds harvested in 2023, while the electrical conductivity was higher in the seeds harvested in 2023. The content of avenanthramide was found to be 10 times higher in the 2023 seeds than in those harvested in 2022. The accumulated precipitation in Gangjin in May 2023 was 230 times higher than that in May 2022, and the average relative humidity was high. These conditions created an environment suitable for infection of A. alternata, which were thought to have caused discolored black oat seeds.
The growth of soybean sprout was greatly influenced by watering systems: Fixed watering system (water tub was loaded at ceiling upper of culture box and water was showered by bottom holes) was estimated the better than that of reciprocating watering and tub immersing watering because it could cool down the temperature in culture box and wash the organic substances on the body of sprout. The fixed watering system showed good body color and preventing effect of partial rotting of sprout because it could discharge $\textrm{CO}_2$ gas effectively in culture box and keep the concentration below 5%. The concentration of gases at the bottom (about 30 cm height from basal plate) of culture box in fourth or fifth days was L6% for $\textrm{CO}_2$ and 13-16% for $\textrm{O}_2$, respectively. The optimum gas concentration in culture box was considered to be over 10% for $\textrm{O}_2$ and below 5% for $\textrm{CO}_2$.
Purpose: Although radiation-induced fibrosis is one of the common sequelae occurring after irradiation of skin and soft tissues, the treatment methods are not well standardized. This study aimed to establish the skin fibrosis mouse model by fractionated radiation for the further mechanism studies or testing the efficacy of therapeutic candidates. Materials and Methods: The right hind limbs of BALB/c mice received two fractions of 20 Gy using a therapeutic linear accelerator. Early skin damages were scored and tissue fibrosis was assessed by the measurement of a leg extension. Morphological changes were assessed by H&E staining and by Masson's Trichrome staining. TGF-${\beta}1$ expression from soft tissues was also detected by immunohistochemistry and PCR. Results: Two fractions of 20 Gy irradiation were demonstrated as being enough to induce early skin damage effects such as erythema, mild skin dryness, dry and wet desquamation within several weeks of radiation. After 13 weeks of irradiation, the average radiation-induced leg contraction was $11.1{\pm}6.2mm$. Morphologic changes in irradiated skin biopsies exhibited disorganized collagen and extracellular matrix fibers, as well as the accumulation of myofibroblasts compared to the non-irradiated skin. Moreover, TGF-${\beta}1$ expression in tissue was increased by radiation. Conclusion: These results show that two fractions of 20 Gy irradiation can induce skin fibrosis in BALB/c mice accompanied by other common characteristics of skin damages. This animal model can be a useful tool for studying skin fibrosis induced by radiation.
This study was conducted to know the quality of marketed green teas which were devided into high, middle and low grade according to the price. we examined the content of water, ash, total nitrogen, tannin, caffeine, chlorophyll and color value and did sensory evaluation. The results were as follows: 1) The content of water was 2.17-3.67% and content of ash was 4.50-5.17%, there were no significant difference in each grade. 2) The content of total nitrogen was 4.38% in high grade, 4.60% in middle grade and 4.68% in low grade. 3) The content of tannin was 11.09% in high grade, 14.22% in middle grade and 14.44% in low grade, middle and low grade were significantly higher than high grade. 4) The nitrogen rate to tannin (N/T) was 39.5% in high grade, 32.6% in middle grade and 32.70% in low grade, N/T rate of high grade was significantly highest than others. 5) The content of caffeine is 1.78% in high grade, 1.32% in middle grade and 0.92% in low grade, high and middle grade were significantly higher than low grade. 6) The content of total chlorophyll is 297.37 mg% in high grade, 192.89 mg% in middle grade and 204.79 mg% in low grade, chlorophyll a was 69.23 mg% in high grade, 51.99 mg% in middle grade and 63.42 mg% in low grade, and chlorophyll b was 228.47 mg% in high grade, 131.21 mg% in middle grade and 141.63 mg% in low grade. 7) Yellow value of high and middle grade were significantly higher than low grade, but blue and red value were no significant diffrence in groups. 8) In sensory evaluation, appearance, taste, odor of high grade were better than others and total score was 15.25 in high grade, 12.97 in middle grade and 9.80 in low grade. 9) Price had a positive correlation with caffeine, appearance and taste, but a negative correlation with tannine. NT rate had a negative correlation with tannine, but a positive correlation with caffeine.
Appenzeller cheese samples were prepared by addition of 0.5, 1.0, and 2.0% green tea (Camellia sinensis, CS) powder and control cheese. We examined various quality characteristics of the novel cheese, such as viable-cell counts, pH, water-soluble nitrogen (WSN), non-casein nitrogen (NCN), non-protein nitrogen (NPN), and catechin level during maturation for 16 weeks at $14^{\circ}C$. To develop a Korean natural cheese containing green tea powder, we also analyzed the changes in the polyacrylamide gel electrophoresis pattern, chemical composition, and sensory qualities. The viable cell counts of the samples were not significantly different. Until the $3^{rd}$ week, the pH of the CS cheese decreased with an increase in the maturation time. However, the pH gradually increased by the $12^{th}$ week, while WSN, NCN, NPN also increased. The WSN, NCN, NPN, and catechin values for the CS cheese samples were significantly higher than the values for the control cheese. The polyacrylamide gel electrophoretic pattern of caseins for the CS cheese indicated that this cheese degraded more rapidly than the control cheese did. In the sensory evaluation, cheese with 1.0% CS powder showed the highest scores in taste and appearance and good scores in flavor and texture. These results indicate that 1.0% CS is the optimal value for addition to cheese, and cheese containing 1.0% CS shows good physiological properties and reasonably high overall sensory acceptability.

The present study investigated the relationship between physical conditions and sensory properties of red pepper powder stored at different temperatures ($-20^{\circ}C$, $0^{\circ}C$, $20^{\circ}C$) and in different wrap materials (linear low density polyethylene, LLDPE; aluminum/linear low density polyethylene, Al/LLDPE). Red pepper powders with initial moisture contents of $17.35{\pm}0.32$% were not affected by the packaging material or storage temperature. Hunter a values of red pepper powder decreased while Hunter b values increased as storage temperature increased. There were no significant differences according to packaging materials. The American Spice Trade Association (ASTA) color value ($60.85{\pm}0.13$) significantly decreased with increasing temperature from $-20^{\circ}C$ to $20^{\circ}C$ ($21.70{\pm}0.06$ to $56.03{\pm}0.24$). The ASTA color value of samples packed with LLDPE ($21.70{\pm}0.06$) decreased more compared to samples packed with other materials. Further, capsanthin contents ($13.74{\pm}0.02$ mg/100 g) significantly decreased with increasing temperature from $-20^{\circ}C$ ($0.25{\pm}0.01$ to $0.28{\pm}0.01$ mg/100 g) to $20^{\circ}C$ ($0.13{\pm}0.01$ to $0.25{\pm}0.01$ mg/100 g). In the sensory evaluation of red pepper powder, overall acceptability was influenced by redness, yellowness, and pungency color. All physicochemical and sensory properties of red pepper powder were compared. Hunter a values, ASTA color values, and capsanthin contents were significantly associated with sensory preferences. In particular, ASTA color value showed a close relationship with color preference for red pepper (R2=0.922). Thus, we suggest that the preference for red pepper powder can be determined based on instrumental measurements of Hunter a values, ASTA color values, and capsanthin contents.

This study was conducted in order to investigate the quality characteristics and antioxidant activities of dry noodles with addition of sorghum (Sorghum bicolor L. Moench) flour from glutinous and non-glutinous varieties. The sorghum varieties used in this study were glutinous 'Hwaggumchal' and non-glutinous 'Donganme', and the contents added to noodles were 'Hwaggumchal' 5%, 'Hwaggumchal' 10%, 'Donganme' 5%, and 'Donganme' 10%. The turbidity of soup of cooked noodles was increased by addition of sorghum flour. The cooking loss of 'Hwaggumchal' flour added noodles (HFN) was greater than that of 'Donganme' flour added noodles (DFN), reflecting endosperm characteristics. Phenolic compounds such as polyphenol, flavonoid, and tannin contents and antioxidant activity of sorghum flour added noodles were increased in proportion to the amounts of added sorghum flour. In the added varieties, DFN showed greater amounts of phenolic compounds and higher levels of DPPH and ABTS radical scavenging activities than HFN. The DPPH and ABTS radical scavenging activities of 5~10% DFN were increased by 4.6~6.2 fold and 10.5~13.4 fold, respectively, compared to non-added noodles. Regarding cooking effects, DPPH and ABTS radical scavenging activities of sorghum flour added noodles were increased by 10.9~11.2% after cooking. In sensory evaluation, color and appearance value were highest in HFN, and no differences in taste and overall acceptability were observed among treatments.
Effects of supplemental levels of Bomboo vinegar(BV) on growth performance, serum profile and meat quality in 15 Korean native Hanwoo cows was investigated. Concentrate diet was supplemented with Bamboo vinegar with 3% and 6% of the diet. Daily weight gain was increased slightly at 3% BV, but it was decreased in 6% BV. Feed intake was decreased(P<0.05) at 6% BV. Glucose concentration of serum profile was decreased(P<0.05) at 3% and 6% BV. Total protein and cholesterol concentrations were increased(P<0.05) at 3% and 6% BV. BUN concentration was increased(P<0.05) at 3% BV. In carcass characteristics the longissimus muscles of all BV treatments showed no significant(P<0.05) effects, but back fat thickness was decreased significantly(P<0.05) in 6% BV. Marbling score was increased significantly(P<0.05) at 3% BV, thus improving the meat quality. Cut meat production was not difference by treatment. Crude fat content of proximate chemical composition in longissimus muscle was increased(P<0.05) in 3% BV. Shear force and cholesterol contents were decreased(P<0.05) in 3% and 6% BV. The 16:0 of fatty acid composition in longissimus was decreased(P<0.05) whereas 18:1 was increased(P<0.05) at 3% and 6% BV. The composition of saturated fatty acids(SFA) was decreased(P< 0.05), whereas unsaturated fatty acids(USFA) was increased(P<0.05) in 3% BV. Odor and appearance of sensory evaluation were not difference by treatment. Taste was improved significantly (P<0.05) in 3% and 6% BV with the peculiar and savory taste of Hanwoo being more emphasized. The results of this experiment indicated that 3% BV improved the marbling score and crude fat content, decreased the shear force and cholesterol contents, increased the USFA composition, and improved the taste of sensory evaluation in Korean native Hanwoo cows.
To meet the needs of Muslim consumers, sausages were prepared using Halal-certified chicken thighs and different amounts of biji powder (0, 20, 30, 40, and 50%), and then the properties of the sausages were compared. As the biji powder levels increased, both the moisture content and the pH of the sausages significantly decreased, whereas their fiber content increased. As the biji powder levels increased, the free radical scavenging effect (DPPH, ABTS) and water holding capacity also increased, and the textural properties also improved. When Muslim consumers evaluated the sensory attributes of the sausages prepared in this experiment and those currently on the market, the ones prepared in this experiment were preferred over the market products. Based on the above results, chicken sausage for Muslim consumers could be successfully produced, and their overall quality and antioxidant effects could be improved by the addition of biji powder (up to 30%).
