  • This article examines the types and cooking methods for tteok (Korean rice cake) according to its sub-ingredients, as recorded in 18 old literatures of the Joseon dynasty (1392~1909). The sub-ingredients used in tteok during the Joseon dynasty were categorized into flowers, fruits, vegetables, Korean typical medicinal plants, and others. In the early, middle, and late eras of the Joseon dynasty, one, six, and 14 kinds of tteok were prepared using flowers as the sub-ingredient and two, seven, and 32 kinds of tteok were prepared using fruits, respectively. Three, seven, and 38 kinds of Tteok were prepared using vegetables as the sub-ingredient, while there were three, five and 15 kinds tteok prepared using Korean medicinal plants, respectively. One, five, and 13 kinds of tteok were prepared using other ingredients such as fish and seogi mushrooms in the early, middle, and late eras of the Joseon dynasty, respectively. The types of sub-ingredients and the resulting types of tteok increased throughout the Joseon dynasty, indicating that flowers and vegetables were preferred the most among tteok sub-ingredients. Tteoks using flower as the sub-ingredient, whajeon, were mostly jijin-tteok. The types of tteok and cooking methods using other sub-ingredients were discussed in terms of the type of sub-ingredients and their treatment to prepare tteok. The sub-ingredients were mixed with flour, which was the main ingredient for preparing tteok, or ground and shredded to prepare gomul for decorating and stuffing tteok, respectively. It seemed that the appearance and taste of tteok varied, thereby resulting in nutrient supplementation as the kinds of sub-ingredients increased throughout the Joseon dynasty. We expect that the recipes and ingredients as well as the cooking methods recorded in these old articles will contribute to those looking for a healthy life and, furthermore, to the globalization of tteok.

  • This study was carried out to develop a new product using Cheonggukjang (fermented soybean product) and sub-ingredients(lactic acid bacillus powder, chlorella, lactose, green tea). Fresh Cheonggukjang was dried by a infrared drying(50℃, 36hr) and powdered by a roll mill. The powder was mixed with sub-ingredients and then moulded as tablet type by a press moulder. The pH of tablet was low with the addition of lactobacillus and total sugar content was high with the addition of lactose. Disintegration, absorption capacity and textural properties of tablet were not affected by the addition of any sub-ingredient. Color of non-added tablet was yellow to red, but changed to green when chlorella was added. Sensory properties(color, taste, flavor, chewiness, hardness, acceptability) were not affected by the addition of sub-ingredients. The results indicate that functional healthy tablet could be made from Cheonggukjang powder and various sub-ingredients.

  • Effects of various sub-ingredients (hot pepper, garlic, ginger, green onion, leek, salted and fermented anchovy juice, and sugar) on the sensory quality of Korean cabbage kimchi were investigated. Sixteen sensory attributes were selected and their intensities evaluated by 20 panelists. The kimchi had an unbarmonized taste and unpleasant flavor when fermented with individual sub-ingredients, but had a well harmonized taste when fermented with all sub-ingredients. Hot pepper, ginger and garlic contributed to reduction of the unpleasatnt taste and moldy odor. The strong garlic flavor was reduced by adding green onion and leek. Salted and fermented anchovy juice gave a palatable taste, and the overall taste was improved by adding sugar. All sub-ingredients except sugar reduced the sour tasts.

  • This study was designed to determine the apparent digestibility coefficients of soybean meal, soy protein concentrate (SPC), soy protein isolate (SPI), rapeseed meal (RSM), pea protein concentrate (PPC), wheat gluten meal (WGM) and wheat flour (WF) for olive flounder, Paralichthys olivaceus. A reference diet (RF) was formulated to meet the nutrient requirements of olive flounder with 1% chromic oxide (Cr2O3) as an inert indicator. Test diets were prepared to contain 70% RF and 30% of the test ingredient. Olive flounder, averaging 150 ± 8.0 g, was cultured in 400-L fiberglass tanks at a density of 25 fish per tank. Fecal collection columns were attached to each tank. Fecal samples were obtained from triplicate groups of fish for 4 weeks. Dry matter digestibility of SPC (75%) and WGM (76%) were significantly higher than the other test ingredients. Protein digestibility of SPC (85%), PPC (88%) and WGM (89%) were significantly higher than the other test ingredients, and protein digestibility of RSM (77%) and WF (76%) was lower than the other ingredients tested. Lipid digestibility of SPC (72%) and SPI (69%) were significantly higher than the other test ingredients. Energy digestibility of SPC (85%) and WGM (82%) were significantly higher than that of others tested ingredients. The availability of amino acids in WGM was generally higher than in other plant-feed ingredients. Therefore, SPC and WGM were seems to be efficient as potential protein sources for olive flounder compared to other tested ingredients. Overall, findings of the current study may assist in more efficient and economical formulation of diets using plant feed ingredients for olive flounder.

  • Apparent digestibility coefficients (ADCs) of dry matter, crude protein, crude lipid, nitrogen-free extract, energy and essential amino acids in animal-based feed ingredients were determined for olive flounder (Paralichthys olivaceus). A reference diet (RF) was formulated to contain 1.0% chromic oxide (Cr2O3) as an inert indicator. Nine test diets were formulated to contain RF and one of the feed ingredients (pollock meal [PM], jack mackerel meal [JMM], anchovy meal [AM], cod meal [CM], sardine meal [SM], sand eel meal [SEM], tuna meal [TM], meat meal [MM] and squid liver meal [SLM]) at a 7:3 ratio in each diet designated as PM, JMM, AM, CM, SM, SEM, TM, MM and SLM, respectively. Olive flounder, averaging 150 ± 8.0 g, were stocked at a density of 25 fish per tank in 400-L fiberglass tanks attached with fecal collection columns. Feces were collected from triplicate groups of fish one time a day for four weeks. Dry matter and crude protein ADCs of CM and SEM were significantly higher than the other tested ingredients. Lipid ADCs of JMM, CM and SEM were significantly higher than the other test ingredients. Energy ADCs of CM and SEM were significantly higher than that of the other tested ingredients. The availability of amino acids in CM was generally higher than the other animal protein sources. PM exhibited the lowest amino acid availability among the treatments. Interestingly, MM exhibited significantly higher nutrient digestibility than several marine-based ingredients. However, CM and SEM are seeming to be highly digestible and effective to use in olive flounder diet compared to the other tested ingredients. Overall, the results of this study provide information about the bioavailability of nutrients and energy in animal feedstuffs to apply when formulating cost-effective practical feeds for olive flounder.

  • The volatile flavor compounds of kimchi and its sub-ingredients were analyzed using GC/MS. The major volatile compounds of kimchi were identified as sulfide compounds, organic acids and alcohols. It was confirmed that the major volatile flavor compounds of kimchi originated from sub-ingredients such as garlic, ginger, onion and reek. To reduce the characteristic odor of kimchi, the sub-ingredients (garlic, ginger, onion and reek) were chopped into a length of 5 mm and a thickness of 0.3 mm, blanched at 100${^{\circ}C}$ for 2 min, and then soaked in water at 4${^{\circ}C}$ for 12 hr. The effects of soaking of the sub-ingredients on sensory evaluation with regard to characteristic odor of kimchi such as sour and moldy odor were investigated. The sour and moldy odors of kimchi were significantly reduced by the soaking of sub-ingredients. Additionally the addition of soaked sub-ingredients in kimchi had influences on the change of pH, total acidity and lactic acid bacterial count of kimchi during fermentation.

  • This study was conducted to investigate the effects of pre-treated sub-ingredients and deodorization materials on the smell intensity of Kimchi during fermentation.Among the various sub-ingredients of Kimchi, garlic, ginger and green onion have comparatively strong smell. The smell intensities of the sub-ingredients, which were pre-treated with various patented methods were examined using the sensory evaluation method and AromaScan. The results showed that the good methods to reduce the smell of sub-ingredients were hot air drying and soaking with heating treatment. The pH, titratable acidity and the number of microorganism of Kimchi prepared with pre-treated sub-ingredients were not different among samples during fermentation. The smell intensity of the Kimchi with pre-treated sub-ingredients was weaker than that of control until ten fermentation days, but the smell intensity after 10 days of fermentation was not different among samples. The addition of ${\alpha}-cyclodextrin\;and\;{\beta}-cyclodextrin$, which are known to have deodorization effect, at a level of 0.1% respectively, to Kimchi resulted in no difference in the pH, titratable acidity and smell intensity during fermentation at $10^{\circ}C$ compared to those of control Kimchi. However, the addition of deodorizer reduced sulfide classes such as methyl allyl sulfide, dimethyl disulfide, allyl sulfide, methyl propyl disulfide up to 50%.

  • The domestic marine healing industry is undergoing significant revitalization efforts, with a focus on understanding the efficacy and effectiveness of marine healing resources. This study establishes utilization and management standards through a detailed analysis of the active components within well-recognized marine healing mud materials. Samples of mud materials were collected from domestic tidal flats. These samples exhibited an average composition of 7.87% sand, 74.95% silt, and 17.17% clay, with a combined mud content (silt+clay)(silt+clay) consistently exceeding 90%. Notably, SiO2 emerged as the most prevalent effective ingredient at 68.4%, followed by Al2O3 (13.3%)>Fe2O3 (4.0%)>K2O (2.9%)>Na2O (2.3%)>MgO (1.6%)>CaO (1.0%)>TiO2 (0.7%), in terms of average content. Subsequently, through an analysis of effective ingredients, Si, Al, Fe, K, Na, Mg, and Ca were identified as elements demonstrating significant functionality. Among these, key indicator ingredients were selected for quality control, all of which were found to possess efficacious properties. Notably, K, Mg, and Ca exhibited particularly high concentrations. Based on these findings and referencing existing literature, it is recommended that domestic tidal flat mud resources earmarked for utilization as marine healing resources should possess a raw material mud content of no less than 70.0%. Moreover, the cumulative index components K2O+MgO+CaO should meet or exceed a threshold of 5.0% for optimal effectiveness.

  • As the interest in sustainable and environmentally friendly agriculture continues to grow, there is a corresponding increase in organic fertilizers utilization. However, studies on ammonia (NH3) emissions, which are primarily generated in the agricultural sector, by organic fertilizers are lacking. Additionally, the reliance on imported ingredients in the production of organic fertilizers hinders the widespread adoption of organic fertilizers. This study aims to evaluate NH3 volatilization by incorporating rice husk biochar into organic fertilizers. The study also aims to assess whether domestically produced rice husk biochar can serve as a viable substitute for imported ingredients. Here, the dynamic chamber method was used under controlled conditions. Results show that inorganic fertilizers readily undergo hydrolysis, thereby rapidly generating significant amounts of NH3, particularly in the initial stages. In contrast, organic fertilizers decompose gradually, leading to relatively long-term NH3 emissions. The incorporation of rice husk biochar into organic fertilizers demonstrated diminished daily NH3 emissions compared to those from commercial organic fertilizers, resulting in decreased total NH3 volatilization. These findings show that the combination of rice husk biochar can reduce NH3 volatilization and serve as an alternative to imported ingredients for organic fertilizers. The results of this study can be utilized as fundamental information for the assessment of biochar as a potential ingredient for organic fertilizers.

  • Tribological properties of high temperature fade were investigated by changing relative amounts of ingredients in the brake friction material. Based on a simple experimental formulation containing 10 ingredients, friction materials were tested using a pad-on-disk type friction tester. Twenty-five friction material specimens with different relative amounts of the ingredients were manufactured according to the constrained mixture design .The difference ($\Delta$${\mu}$=${\mu}$$\sub$max/. -${\mu}$$\sub$min/. ) of friction coefficients was measured to represent the high temperature fade. Results from elevated temperature tests showed that five ingredients including cashew, graphite, Sb$_2$S$_3$, ZrSiO$_4$, and Cu fibers played important roles on $\Delta$${\mu}$. In order to find relative importance on fade phenomena among these ingredients, ANOVA(analysis of variance) was performed in this investigation. Thirty-two friction material specimens by changing ${\pm}$50vol.% of these five ingredients were tested to examine the relative importance. Results showed that cashew, graphite '||'&'||' Sb$_2$S$_3$, and cashew '||'&'||' graphite aggravated the fade behavior and Cu fibers improved on fade resistance.
