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 research was conducted to evaluate consumers' understanding and preference for shelf life and ingredient listings in food label by survey using a questionnaire. The questionnaires were collected from female adult consumers residing in Seoul, Kyonggi, Choongnam and Chungbuk areas. Most of the consumers showed good understanding for shelf life and ingredient listings in food label. They had no particular preference for the types of shelf life labelling. They preferred listing all ingredients completely with amounts, but differentiated from food additives. They wanted to get more information about shelf life and ingredient listings in food label that is mainly associated with food safety They showed more preference for labelling the shelf life in the information panel with a storage condition. Most of them chose the ingredient list format in which each ingredient was written in one row in bold characters with percentage labelling.

The objective of this study was to develop a stock that can be used to make a variety of dishes. For this, stock was prepared with beef, chicken, and pork meat as animal meats as well as anchovy, mushroom, and sea tangle as other ingredients. The qualities of six[only four though] kinds of stocks made with beef only (B), beef and chicken (BC), beef and pork (BP), and beef added with chicken and pork (BCP), and seven kinds of stocks made with anchovy (A), mushroom (M), sea tangle (S), anchovy and mushroom (AM), anchovy and sea tangle (AS), mushroom and sea tangle (MS), and anchovy added with mushroom and sea tangle (AMS) were investigated by sensory evaluation. The most preferred stock made with animal meat was mixed with the most preferred stock made with other ingredients at a 5% level to test the synergistic effects of palatability. As a result, BCP stock and AMS stock obtained the highest scores for overall preference. BCP stock within the range of 30%-65% along with the mixed stock containing AMS (35%-70%) showed synergistic effects for palatability.

N,N-Diethyl-m-toluamide is the active ingredient in insect repellant against malaria mosquito. It is remarkable that if the methyl group is in either of the other isomeric positions(ortho or para) the compound is ineffective as an insect repellant. Semiempirical quantum mechanical treatment are applied to these molecules to explain the difference, using the extended Huckel theory, the theoretical predictions for the preferred conformation are compared with experimental results.

This study compared the characteristics of consomme prepared by homeskill(Consomme A) and quantity food production skill(Consomme B) as well as by the main ingredients of Consomme. The highest portion of amino acids in Consomme was arginine, followed by glutamic acid and alanine. In sensory evaluation, Consomme A prepared with chicken meat and Consomme B with mixed beef & chicken were most preferred. This result showed that higher total amino acid content gave better sensory scores. There was a significant correlation between the turbidity of sensory evaluation and the color b value. Turbidity and viscosity of instrumental measurement were also significantly correlated.
