  • $D{\acute{o}}ck$ (Korean rice cake) is a peculiar food of Korea made of grain. By means of cooking from, it is defined as 'Pulvberzed food of grain' $D{\acute{o}}ck$ was one of the daily food, but development of boild rice had narrowed it's use to the food of festive days and ceremonies. $D{\acute{o}}ck$ is used as a main food of all Kinds of ceremonies from one's birth to death, such as the Three seven day(a baby's twenty-first day of life), one hunderdth day, birthday, wedding, both brithday, funeral and sacrifical rites, vocational ceremonies, such as a sacrifice to spirits and a srevics for a big catch of fish. It is also used as a present and seasonal food. A large variety of $D{\acute{o}}ck$ is available and its recipe is scientific and reasonable. In this treatise, the Kinds of $D{\acute{o}}ck$ and the frequency of them, the material, the recipe, the measuring unit of material, cooking kitchen utensils and the cooking terms are studied from the books published in Korea from 1670 to 1943. 1. $D{\acute{o}}ck$ was classified as Tcbin $D{\acute{o}}ck$(steamed), Chin $D{\acute{o}}ck$(strikn), Chijin $D{\acute{o}}ck$(fried) and Salmun $D{\acute{o}}ck$(boiled), according to its way of cooking. 2. There were 122 Kinds of $D{\acute{o}}ck$, 57 were Tchin $D{\acute{o}}ck$, 35 Chin $D{\acute{o}}ck$, 20 Chijin $D{\acute{o}}ck$, and 10 Salmun $D{\acute{o}}ck$. 3. There were 34 Kinds of measuring units. Of them, 13 for volume, 4 for weight, 9 for quantity, 4 for length and 4 for the rest. 4.

  • The aim of this study is to look at how pepper was used in traditional medicine. In other words, this study aims to take a look at the process by which the medicinal nature & efficacy of pepper in traditional society was perceived and arranged through the aspects of the use of pepper as an exotic crop for treating diseases. This study investigated cases of using pepper for medical treatments by referring to books on traditional medicine in Korea. The old records about pepper are mainly in empirical medical books from the late Chosun dynasty. Nevertheless, the records about pepper tend to decrease in medical text as time goes by. Such a phenomenon can be attributable to the fact that people began to use pepper for daily food life rather than for medicinal purposes. Pepper was used mostly for digestive trouble such as vomiting, diarrhea, and stomachaches, and it was also applied to mental and aching diseases caused by the sound of body fluids remaining in the stomach. In addition, there were many cases where pepper was used externally for surgical disorders. Such symptoms for treatment are linked to, or in a complementary relationship with, research results in modern times. Boiled pepper was generally taken in the traditional herbal decoction method, and in the case of surgical diseases, it was applied externally. The cases of using old pepper, using pepper with seeds or without seeds, and using pepper mixed with sesame oil belong to a sort of herbal medicine processing, which usually aimed at changing the medicinal nature of pepper. In addition, in relation to the eating habits at that time, pepper was used as seasoning and to make red pepper paste with or without vinegar. There are two words used for pepper in the medical textbooks, 苦椒 (gocho) and 烈棗 (yeoljo). These words are translated into Korean as gochu, so we can identify this word as a nickname for pepper.

  • A 90-d trial was conducted to determine the influence of additives such as pegmatite (Peg), precious stone (PS), grape pomace extracts (GPEx) and complexes of these additives (Peg + GPEx and PS + GPEx) via evaluation of meat quality including sensory properties in 90 d old finishing pigs. There were no significant differences in the approximate composition and physiochemical characteristics, including meat color, among the treated groups. However, the Peg treated group was found to have a higher water holding capacity than the other groups. The shear-force was evaluated as an indicator of hardness and found to be lower in the Peg and GPEx treated groups, and this tendency was greater when the complex of Peg and GPEx was supplied. No significant differences were observed among groups following analysis of the free amino acid composition and fatty acid (FA) composition. Sensory evaluation of the boiled loins showed significantly (p<0.05) better results from pigs fed diets containing Peg and GPEx complex. These results suggest that Peg may improve the water holding capacity and tenderness. In addition, supplementation with a complex of Peg and GPEx may improve tenderness.

  • In order to develop ginseng tea powder with spore forming lactic acid bacteria Lactobacillus sporogenes was used. In the jar fermentor experiment under optimal culture conditions, the number of spore of L. sporogenes reached about $20{\times}10^8\;CFU/mL$ and sporulation rate was 97%. Granulated ginseng tea was made from glucose 7 kg, lactose 2 kg, ginseng extract 1 kg and spores 5 g $(5200{\times}10^8\;CFU/g)$. In the treatment of artificial gastric juice (pH 3.0) for 4 h and artificial bile for 8 h, the survival rate of spores in the granulated ginseng tea was 55.4% and 90.0% respectively. The spores survived 77.6% after incubation for 20 min in boiled water. Its storage stability was about 75% for 12 months at room temperature.

  • Enzyme-linked immunosorbent assay was developed for the analysis of soy protein in foods. Competitive indirect ELISA (ciELISA) was established by using specific antibodies against the heat-stable acidic subunits (AS) of glycinin. Soy proteins in each sample used in this study were solublized in the presence of urea and DTT and boiled at $100^{\circ}C$ for 1hr and then were renatured with a cystine-containing solution. After these treatments, each isolated soy protein (ISP) heated at 60, 70, 80, $90^{\circ}C$ for 10 minutes showed almost the same curve as unheated one in the ciELISA. The detection limit of ISP was 0.3 ${\mu}g/mL$. Anti-AS antibodies have very low reactivities less than 0.1% toward non-meat proteins such as skim milk and casein and did not show any reactivities toward egg white powder and ovalbumin. When laboratory-made sausages containing ISP of $0.5{\sim}3%$ were assayed by ciELISA, the mean recovery was about 83% (C.V., 19%). In addition, the average content of soy protein in commercial sausages was 1.27%.

  • To provide functional properties in fish paste, boiled-dried anchovy [small size (SS) and large size (LS)] powder containing high amount of calcium was added at 0, 1, 2, 5, and 10% (w/w) levels. The properties of fried fish paste were evaluated by determination of sensory properties and physicochemical characteristics such as color, texture, folding test, and calcium contents. Calcium content of the fish paste increased with increasing anchovy amount. Increasing the amount of SS and LS in fish paste tended to decrease lightness, redness in Hunter color value, while increasing yellowness. All samples with 3 mm thickness had good flexibility and did not break even after 4 times folds. The fish pastes containing 10% of anchovy showed the highest values in strength, hardness, adhesiveness. In overall acceptance of sensory evaluation, SS and LS fish paste containing 1% and 2% of anchovy powder did not show any difference in comparison with control. These results suggest that SS and LS anchovy powder can be applied to fried fish paste products to allow for high calcium contents.

  • Vanadium oxide based materials have been studied as novel negative electrode materials in lithium-ion batteries (LIBs) because of their high specific capacity. In this study, potassium metavanadate ($KVO_3$) was synthesized and its electrochemical properties are evaluated as a negative electrode materials. The aqueous solution of $NH_4VO_3$ is mixed with a stoichiometric amount of KOH. The solution is boiled to remove $NH_3$ gas and dried to obtain a precipitate. The obtained $KVO_3$ powders are heat-treated at 300 and $500^{\circ}C$ for 8 h in air. As the heat treatment temperature increases, the initial reversible capacity decreases, but the cycle performance and Coulombic efficiency are improved slightly. On the contrary, the electrochemical performances of the $KVO_3$ electrodes are greatly improved when a polyacrylic acid (PAA) as binder was used instead of polyvinylidene fluoride (PVDF) and a fluoroethylene carbonate (FEC) was used as electrolyte additive. The initial reversible capacity of the $KVO_3$ is 1169 mAh/g and the Coulombic efficiency is improved to 76.3% with moderate cycle performance. The $KVO_3$ has the potential as a novel high-capacity negative electrode materials.

  • The effect of 16 cultivars on the quality of the rice porridge was investigated. The 'Geunnun' had the highest water absorption rate, but the 'Segyejinmi' yield (w/w) was the highest. The total sugar content of the rice porridge was 0.29~8.10%, showing significant variation among the cultivars. High amylose 'Dodamssal' and 'Hwaseonchalbyeo' glutinous rice displayed rotational viscosities of <20,000 cP. Rotational viscosities for boiled rice cultivars were 30,000~40,000 cP, representing an intermediate level, and the rotational viscosities of 'Geonyang2' and 'Hanareum4' were over 50,000 cP. These results suggest that the viscosity of rice porridge varies significantly among raw material cultivars. Among other variables affecting the texture profile of rice porridge, there were significant differences in hardness and gumminess among the cultivars. As a raw material, 'Baekokchal', a kind of glutinous rice, is known to be whiter than the non-glutinous rice, but after processing to porridge, it showed the lowest L value (71.1). Starch degrading enzyme activity was not significant in most types of rice porridges within 30 or 60 minutes. Therefore, enzymatic starch degradation is thought to be completed within 30 minutes. Among the tested raw materials, 'Miho' was 73.5 ㎍/mg, indicating the best digestibility in vitro.

  • This study was conducted to investigate nutrition characteristics of the following major commercially available dried fish (MCDF) in South Korea: plain-dried fish [nogari (PD-N), Alaska pollock (PD-AP), red tongue sole (PD-RTS), and young tidepool gunnel (PD-YTG)], salt-dried fish [(yellow corvina (SD-YC) and red tilefish (SD-RT)], four types of boiled-dried anchovy of different sizes (BD-As), and freeze-dried fish [Pacific saury (FD-PS), Alaska pollock (FD-AP), and Katsuobushi]. The energy content of the MCDF ranged from 103.0 to 420.5 kcal per 100 g. The MCDF in nutritional and functional properties of minerals were SD-RT and Katsuobushi in calcium; none in phosphorus, sodium, or zinc; Katsuobushi in potassium and magnesium; PD-AP, SD-YC, and SD-RT in iron, PD-AP, PD-RTS, SD-YC, and SD-RT in copper; and PD-N, PD-AP, PD-RTS, SD-YC, SD-RT, FD-PS, FD-AP and Katsuobushi in manganese. The total amino acid content of the MCDF ranged from 15.85 to 71.96 g per 100 g; the major amino acids were glutamic acid, aspartic acid, lysine, and leucine. The fatty acid content of the MCDF ranged from 0.81 to 2.93 g per 100 g. The MCFSP expected in nutritional and functional properties of vitamins were PD-N, PD-RTS, FD-PS, FD-AP, and Katsuobushi in riboflavin; PD-N, PD-AP, PD-YTG, BD-As, FD-PS, FD-AP, and Katsuobushi in niacin; PD-N, PD-RTS, SD-YC, and BD-As in vitamin A; and PD-AP, PD-YTG, SD-YC, and FD-AP in vitamin E.
