This study aimed to enhance the applications of dates as a food material that can be utilized and stored easily by improving the inefficient process of the traditional cooking procedure. To this end, this study investigated the physico-chemical and nutritional properties of jujube pulp powder, and compared the traditional and newly developed methods of making yakbap, yakpyon, and jujube porridge. According to the analysis of physical and chemical properties, the jujube pulp powder contained 5.4% moisture, 2.6% crude ash, 6.6% crude protein, 0.35% crude fat, and 4.7% crude fiber. The water activity was 0.95% in jujube pulp while it was 0.24% in jujube pulp powder. In addition, the jujube pulp powder had a total sugar content of 70.4% and reducing sugar content of 6.3%. The vitamin C was content was estimated to be 68.5 mg/100 g in the jujube pulp powder and the jujube pulp contained 6.2 g/100 g of dietary fiber. Major minerals were K, Mg, and Ca. After appointing jujube pulp powder (new method) to a test group and jujube pulp (traditional method) to a control group, the sensory evaluation and acceptance testing were conducted for yakbap, yakpyon, and jujube porridge. As a result, there was no significant difference in any sensory factors tested (p<0.05). It was found that making and storing jujube pulp powder by drying jujube pulp is a useful way of utilizing jujube because Yakbab, Yakpyun and jujube porridge were found to have a relatively good appearance, color, flavor, taste, texture and overall acceptance.
The Physicochemical, sensory and cooking properties of functionally fortified rice with dietary fiber and chitosan were compared with regular rice when the rices were cooked with pressure and electric cookers. Moisture content of functional rice before cooking was 11.11%, which was lower than 13.72% in regular rice. Accordingly, moisture contents of functional rice samples cooked both with pressure and electric cookers were lower than those of regular rice. L value showing the degree of lightness of cooked rice was significantly higher in rice samples cooked with pressure cookers. The ${\alpha}$ value, the degree of redness and the b value, the degree of yellowness, were the highest in the functional rice cooked with an electric rice cookers. Textural measurement of hardness using a rheometer showed the highest value in functional rice cooked with a pressure cooker. The degree of gelatinization measured using differential scanning calorimetry (DSC) before cooking showed higher onset gelatinization temperature ($T_0$) and peak gelatinization temperature ($T_p$) in functional rice compared with those in regular rice. The gelatinization enthalpy (${\Delta}H$) of functional rice was lower than that of regular rice, showing that functional foe had lower gelatinization energy compared with regular rice. When the samples were stored in a refrigerator for one week, the DSC showed faster retrogradation degrees in samples cooked with electric rice cooker, having significantly higher enthalpies of regular and functional rice cooked with electric cooked compared to those cooked with pressure cookers. The functional rice samples cooked with pressure cooker had higher consumer acceptance test values compared to those cooked with electric cookers.
This study aimed to comparatively analyze changes in skin conditions according to the frequency of sheet mask use among women in their 60s. An experiment was performed for 5 weeks from May 1 to June 3, 2020. A total of 70 women in their 60s, who understood the purposes of this study and agreed to the experiment were selected. All empirical analyses were conducted at a significance level of 5%, and the SPSS WIN 21 program was used to perform statistical analysis. Increased moisture content, decreased coarseness, changes in sebum levels, and decreased pigmentation, were significant effects of sheet mask use for 7days per week. As long as the sheet mask did not irritate the skin, had a positive effects on the skin the more often it was used. These results can help in enhancing the effectiveness of systematic measurement and improvement of skin type. To determine factors affecting skin conditions, it is necessary to investigate and compare factors such as effects of dietary or living habits, genetic influence, and living environments.
The purpose of this study was to determine the optimum chemical composition, color value, salinity, pH, total acidity, and texture for the production of short-term Green Gochujang using Cheongyang pepper powder and Meju powder. The results were as follows. The moisture content for Green Gochujang made from Cheongyang pepper powder was 33.50% for CON, and 27.21% for GG1. Crude fat and crude protein contents increased as the amount of added Meju powder increased (p<0.001). GG1 and CON contained 9.47% and 9.05% crude ash contents. Water activity was between 0.89 to 0.90. A higher amount of added Meju powder resulted in an increased color L value (p<0.001). CON showed the highest a value and b value compared to GG4, which had the lowest a and b values. Salinity was between 5.10% to 5.83%, which was lower compared to a former study. CON had a pH of 5.25, and GG4 had a pH of 6.06. Regarding total acidity, CON had a total acidity of 0.85, and GG4 had a total acidity of 0.44. Hardness value was highest in GG1 (1535.63), and lowest in CON (422.07) (p<0.001). GG1 showed the highest value in the adhesiveness property test, whereas CON showed the lowest value. GG1, which contained the highest amount of Cheongyang pepper powder showed the highest gumminess value (698.47). In an acceptance test, CON and GG3 showed the best appearance and scent value. GG3 received the highest interest in taste, texture, and overall quality. Through these results, GG3 made with 150 g of Chengyang Green pepper powder, 200 g of Meju powder, 600 g of starch syrup, 500 g of water, and 75 g of salt showed fine overall sensory interest, and therefore can be used for the production of fine Green Gochujang and Gochujang sauce.

Objective: The objective of the study was to determine the effect of fermented spent coffee ground (FSCG) on nutrient digestibility and nitrogen utilization in sheep. Methods: Fermentation of spent coffee ground (SCG) was conducted using Lactobacillus plantrum. Fermentation was performed at moisture content of 70% and temperature of $39^{\circ}C$ with anaerobic air tension for 48 h. Four adult rams (initial body weight = $56.8{\pm}0.4kg$) were housed in a respiration-metabolism chamber and the treatments were: i) control (Basal diet; 0% SCG or FSCG), ii) 10% level of SCG, iii) 10% level of FSCG, and iv) 20% level of FSCG in $4{\times}4$ Latin square design. Each dietary experiment period lasted for 18-d with a 14-d of adaptation period and a 4-d of sample collection period. Results: In SCG fermentation experimental result, acid detergent insoluble nitrogen (ADIN) concentration of FSCG (64.5% of total N) was lower than that of non-fermented SCG (78.8% of total N). Digestibility of dry matter and organic matter was similar among treatment groups. Although crude protein (CP) digestibility of the control was greater than FSCG groups (p<0.05), the 10% FSCG group showed greater CP digestibility and nitrogen retention than non-fermented 10% SCG group (p<0.05). Body weight gain and average daily gain were linearly decreased with increasing FSCG feeding level (p<0.05). When the feeding level of FSCG was increased, water intake was linearly increased (p<0.05). With an increasing FSCG level, dry matter intake did not differ among groups, although the gain to feed ratio tended to decrease with increasing level of FSCG (p<0.10). Conclusion: Microbial fermentation of SCG can improve protein digestibility, thereby increasing CP digestibility and nitrogen utilization in sheep. Fermentation using microorganisms in feed ingredients with low digestibility could have a positive effect on improving the quality of raw feed.
Effects of punching and drying process on quality of Yukwa were determined. Lightness (L) of Yukwa dough with punching was higher than that with no punching. Air cell distribution of Yukwa dough was fine with higher punching. Microstructure of Yukwa dough showed a broken surface structure with increasing punching. Hardness and adhesiveness of Yukwa dough decreased after 5 min of punching and then increased with higher punching. Expansion ratio of Yukwa base with punching at 155 rpm for 5 min was highest among the samples. Appearance of Yukwa base with no punching showed a poor shape and cross section, whereas Yukwa base with punching at 95 rpm for 10 min showed the best appearance and cross section and Yukwa base with punching at 155 rpm for 5 min also showed good appearance. The moisture content of Yukwa Bandegi after 24 hr of drying was 14.93%. Microstructure of Yukwa Bandegi showed a broken surface structure and empty spaces with increased drying time. Expansion ratio of Yukwa base with 24 hr of drying at $40^{\circ}C$ was highest among the samples. Overall, optimum punching conditions were 10 min of punching at 95 rpm or 5 min of punching at 155 rpm and optimum drying condition was 24 hr of drying at $40^{\circ}C$.
The quality of Jeung-pyun made with frozen rice batter was evaluated according to variations in the freezing temperature of the batter. The physicochemical sensory and rheological characteristics of Jeung-pyun were analyzed. The rice batter was stored at -20$^{\circ}C$, -40$^{\circ}C$, and -70$^{\circ}C$ for up to 4 weeks. Statistical data analysis was completed using the SAS program. The pH, and brix percentage of Jeung-pyun batter decreased during the fermentation. In carbon dioxide evolution during fermentation, the levels of the sample stored at -40$^{\circ}C$:, and -70$^{\circ}C$ for 3$\sim$4 weeks were significantly higher than that of the sample stored at -20$^{\circ}C$. The Jeung-pyun moisture content was not significantly affected by freezing temperature or storage times. Specific volume of Jeung-pyun made with rice batter stored at -40$^{\circ}C$, and -70$^{\circ}C$ for 4 weeks was significantly higher than that stored at -20$^{\circ}C$. In sensory evaluation of the stored sample for 4 weeks, the overall quality of Jeung-pyun was not significantly different between with the control and the -20$^{\circ}C$ sample, and between the control and the -40$^{\circ}C$ sample. Among the rheological properties measured with a rheometer on Jeung-pyun made with batter stored sample for 4 weeks at -20$^{\circ}C$, -40$^{\circ}C$ and unfrozen batter, the hardness was increased over the storage time, but the difference was not significant. In conclusion, the most suitable freezing temperature of the rice batter for the manufacture of Jeung-pyun was proposed to be -40$^{\circ}C$.

Breakfast sausages containing 1, 2, 3, and 4% sea tangle powder (Lamina japonica) were prepared. No differences were found in moisture, protein, and fat contents among the control and treatments. However, the ash content increased with increasing amounts of sea tangle powder (p<0.05). The pH levels in the treated samples were lower than the control in both the meat batters and the breakfast sausages (p<0.05). The $L^*$ and $a^*$ values of the meat batters and breakfast sausages were decreased by the addition of the sea tangle powder, and the control had the highest $b^*$ value (p<0.05). The added sea tangle powder improved cooking loss and improved emulsion stability. The T4 sample (containing 4% sea tangle powder) was shown to have the lowest cooking loss and water loss (p<0.05). The hardness, gumminess, and chewiness of the treatments increased compared to the control due to the presence of dietary fibers in the sea tangle. In the sensory evaluations, the 1% sea tangle powder treatment received a lower color score, but received significantly higher scores for flavor, tenderness, and juiciness (p<0.05). Collectively, the breakfast sausage containing 1% sea tangle powder was determined to have the highest overall acceptability. Altogether, the best results, in terms of physicochemical and sensory properties, were obtained for the breakfast sausage containing 1% sea tangle powder.
