This study examined the ingredients and cooking methods of side dishes in "Chosunmusangsinsikyorijebub" during the year of 1924, approximately. In the recipe for Tang (Guk), there was much use of various parts of beef, fish, shellfish, vegetables, and mushrooms, and soybean paste, hot pepper paste, and soy sauce were used as seasonings. For Chootang and Byulchootang, cinnamon powder was added at the end of cooking. In foods such as Tang (Guk), Gigimi, Chigye, Chim, and steamed dishes, which were made of beef, pork, chicken, various fish, Chinese cabbage, and over ripened cucumbers, and thickened by adding buckwheat powder or wheat powder, the taste of the food was changed by controlling the gravy content. In the recipe for Gorim-Cho, ingredients such as beef, pork, chicken, and various fish were used, which were cooked in boiling water and soy sauce. Boiling or steaming were employed as the cooking methods for Baeksuk, where beef rib Baeksuk was seasoned with salt and fermented shrimp and then boiled. For porgy and herring Baeksuk, the internal organs of the fish were first removed, and then they were steamed with pine needles. Hoei incorporated the flesh of various meats, various beef organs, pork skin, and fish as ingredients, and different dipping sauces and pine nut powder were also used.

This study was carried out to investigate the effects of pine needle extract on the color, hardness, springiness, chewiness, pH, thiobarbituric acid reactive substances (TBARS) value, and total bacterial number of seasoned pork meat stored at $4^{\circ}C$ for 9 days. The pH levels of sauce samples were not affected by the mixing rate of the extracts. Acidity, soluble solids, and salinity gradually increased as the amount of added extract increased. Total polyphenolic contents in the sauce ranged from $1.01{\pm}0.02$ mg GAE/mL to $1.41{\pm}0.04$ mg GAE/mL, DPPH radical scavenging activity ranged from $0.06{\pm}0.01$ AEAC to $0.12{\pm}0.01$ AEAC, and ABTS radical scavenging activity ranged from $0.11{\pm}0.01$ AEAC to $0.19{\pm}0.01$ AEAC. The pH levels significantly decreased as the amount of added extract increased. The lightness ($L^*$), redness ($a^*$) and yellowness ($b^*$) values of meat tended to decrease with longer storage period (p<0.05). Hardness and chewiness also increased with longer storage period (p<0.05). The TBARS values decreased as the amount of added extract increased after 6 days (p<0.05). Total bacterial numbers of P5, P10, and P15 decreased compared to the control (p<0.05). In the sensory evaluation, taste and palatability were not significantly different among C, P5, and P10 (p<0.05). Further, flavor, color, tenderness, and juiciness were not different among the seasoned pork meats. These results suggest that pine needle extract can inhibit protein degradation, lipid oxidation, and bacterial growth when used as an additive to seasoned pork meat.

This study was carried out to investigate the effect of lipid type on the physicochemical properties and sensory score of pork patties. The samples consisted of pork patties containing 20% pork fat (PP), 20% olive oil (OP), and 20% soybean oil (SP). The surface color, water holding capacity, increased rate in thickness, decreased rate in diameter, rheological properties, pH, VBN content and TBARS value were determined for the pork patties as the physicochemical properties: the sensory scores were also evaluated. The $L^*$ value for PP was the highest, and the lowest for OP among the samples (p<0.05). For the $a^*$ value OP was the highest among the samples, and the $b^*$ value of OP was lower than that of the PP (p<0.05). The water holding capacity and increased rate of thickness were higher for PP than for OP and SP (p<0.05). The cooking loss and decreased rate of diameter of PP were lower than those of OP and SP (p<0.05). The hardness and springiness of OP and SP were higher than those of PP, and SP had the highest chewiness among the samples (p<0.05). However, cohesiveness and gumminess were not different among the samples. The pH of SP was the highest among the samples, and the TBARS value of OP was lowest (p<0.05). The VBN contents were not different among the samples. The amounts of raw color for OP and SP were higher than that of PP (p<0.05). The raw aroma was not different among the samples. Also, roasted aroma and taste were not different among the samples, but the tenderness, juiciness, and palatability of SP were the highest among the samples (p<0.05).

This study investigated the effects of saltwort powder on the antioxidant activity and quality characteristics of patties added with saltwort powder. Patties were prepared with different amounts (0, 1, 2, and 3%) of saltwort powder. The total phenolic content, DPPH free radical scavenging activity, and pH of patties increased with increasing saltwort powder content (P<0.05). In particular, the moisture content and cooking loss of the group added with 2% saltwort powder were the highest and lowest, respectively (P<0.05). As the content of saltwort powder increased, $L^*$ and $a^*$ values decreased while $b^*$ value increased. Texture analysis showed that the hardness, chewiness, and gumminess of the control group were lower than those of the treated group (P<0.05). Consumer acceptability showed that 1% and 2% saltwort powder groups scored higher in terms of overall preference, appearance, color, taste, and texture compared to the other groups. Characteristic intensity rating of saltwort patties showed that as more saltwort powder was added, saltwort taste intensified; however, the increase did not affect juiciness, off flavor, or salty taste of the patties. Judging from the results, it was concluded that the addition of saltwort powder to patties in processing can enhance the preference, quality, and antioxidant activities of the patties, which elevates the value of patties.

This study examined the antioxidant and antimicrobial activities of 70% ethanol extracts and water extracts of Allium hookeri root. We evaluated the effects of water extracts of A. hookeri root on storage of seasoned pork added with water extracts at $4^{\circ}C$ for 21 days in order to evaluate its potential as a functional food material. A. hookeri root water extracts displayed antioxidant activities (total polyphenol content and DPPH and ABTS radical scavenging activities) that were superior to those of 70% ethanol extracts. The 70% ethanol extracts and water extracts of A. hookeri root showed antimicrobial activities against food-borne Staphylococcus aureus bacteria that were about 1/400 times greater than that of vancomycin. Chemical composition analysis was conducted on pork seasoned with sauce containing 5%, 10%, and 15% water extracts. Moisture and crude ash contents significantly decreased as the amount of water extracts increased (P<0.05), and the highest crude protein content was in the 10% group. Acidity of seasoned pork increased proportionally in the early stages of storage, whereas it significantly decreased as the amount of water extracts increased after day 12 (P<0.05). Although the total number of bacteria in seasoned pork continuously increased during storage, growth of bacteria was significantly restricted as level of A. hookeri root water extracts increased (P<0.05). In the sensory evaluation, pork seasoned with 10% A. hookeri root water extracts showed the highest scores for taste, texture, and overall acceptance (P<0.05). In summary, A. hookeri water extracts display antioxidant and antimicrobial activities that can improve quality characteristics of seasoned pork and have potential as natural preservatives to restrict bacteria growth. Regarding the amount of extracts, 10% was determined to be the most appropriate level to minimize changes in seasoned pork during storage and improve sensory quality.

The sauce is very important to western dishes and also to value and relish of dishes because taste, appearance and the degree of water content are determined by sauce. Also, the taste derived from major sauce like a demi-glace and the basic sauce that affects cooking quality are highly recognized, but preference analyses of source and researches on each ingredients have not been performed up to now. Until today, sauces act as lubricants which add relish to dishes and aid digestion, so the importance of source is more emphasized to raise the taste, appearance, water content and specially healthy function of main ingredients. In this research, some problems of sauce itself and possibilities of improvement was grasped and then some remedies were suggested through the preference, variety and quantity analyses of demi-glace sauce practically used in hotels and restaurants around Gwang-Ju City and South Jeolla(Chon-Nam) Province. Finally, the volume of demi-glace sauce with various ingredients was suggested for various kinds of application. Through the actual proof analysis, preference of each sauce made from various kinds of ingredients was investigated. The result shows that the sauce made from beef bone is highly preferred, followed by pork bone and lamb bone. The least preferred is chicken bone.

BACKGROUND/OBJECTIVES: The consumption of home meal replacement (HMR) is increasing among college students in Korea and China. In particular, Chinese college students studying abroad in Korea (CSK) show changes in their dietary behavior after migration, and HMR consumption for meal substitution is also increasing. This study was conducted to compare the HMR consumption behaviors and HMR development needs of CSK, Chinese college students in China (CSC), and Korean college students in Korea (KSK). SUBJECTS/METHODS: The subjects were 570 college students (180 CSK, 200 CSC, and 190 KSK) who had experience of HMR consumption. Data were collected by face-to-face survey in 2019 and analyzed using SPSS 25.0. RESULTS: The majority of the subjects purchased HMR to 'saving time' and 'preventing meal skipping'. Average purchase price per HMR was about 5,000 won for the CSK and KSK, and about 3,000 won for the CSC. The most important attributes when selecting HMR for the CSK and CSC were hygiene, freshness, and taste in that order, while for the KSK were taste, price, and hygiene. Rice was preferred by the KSK while grilled and fried dishes were preferred by the CSK and CSC. In terms of development needs, dessert and meat-based side dishes were highest in all three groups. The preferred food materials for more than 50% of the subjects of all groups were beef, chicken, pork, shrimp, and squid, and spinach and Chinese cabbage in the CSK, and onion in the KSK. CONCLUSIONS: This study shows more effort is needed to develop the healthy customized HMR for college students studying in Korea and China, and that focuses are placed by CSK on hygiene and freshness, by CSC on meat side dishes, hygiene, and price, and by KSK on snacks (as meal substitutes), taste, and price.
