Biodegradable films were prepared from roasted sesame meal and rice bran. Acetic anhydride, succinic anhydride, and formaldehyde were added to the film-forming solutions, and their effects on tensile strength, percent elongation, water vapor permeability, and water solubility of the films were studied. Roasted sesame meal did not form film without acylation or addition of formaldehyde. Acylated roasted sesame films had higher tensile strength and water-solubility, and lower % elongation than rice bran films. Acylation with acetic and succinic anhydrides increased tensile strength, percent elongation, and water solubility of rice bran films, but decreased water vapor permeability. Treatment with formaldehyde increased tensile strength of roasted sesame and rice bran films and % elongation of rice bran films, while reducing water-solubility of roasted sesame and rice bran films and water vapor permeability of rice bran films.

Changes in physicochemical properties of the defatted sesame meals at various roasting temperature and time have been studied. The roasting temperatures were $190^{\circ}C,\;210^{\circ}C,\;and\;230^{\circ}C,$ whereas roasting times were 5, 10, 20 and 30 minutes, The protein content of defatted sesame meals decreased during roasting and the oil content of the meals roasted at$210^{\circ}C$ for 10 minutes was 8.4%. The yields of sesame mea]s and oil, when roasted at $210^{\circ}C$ for 10 minutes, were 50.1% and 46.9%, respectively. The amino acids in sesame meals gradually decreased as roasting conditions became severe. Sucrose (162.6 mg%), glucose (37.7 mg%) and fructose (18.7 mg%) were detected in the raw sesame meals. The color of roasted sesame seeds and oils extracted from them became darker as the roasting temperature and time increased and the change in lightness greatly affected the total color change. The browning pigment of the sesame meal roasted at $190^{\circ}C$ was separated into a fraction I, II and III. When roasted at $230^{\circ}C$ for longer than 10 minutes, the soluble browning pigment decreased.

Sesame(Sesamum indicum L.) is probably the most ancient oilseed crop known in the world. The seed of sesame is used in a variety of ways as food. The whole seed may be eaten raw, either roasted or parched, or fed to birds and stock. Sesame oil is used as a salad or cooking oil, in shortening, margarine and in the manufacture of soap. Minor uses are as a fixative in the perfume industry and formerly as a carrier for fatsoluble substances in pharmaceuticals such as penicillin. One of the minor constituents of sesame oil, sesamin, is used for its synergistic effect in pyrethrin insecticides, in addition of a small quantity of this substance markedly increases the effectiveness of fly sprays. The meal remaining after oil extraction can be used as and animal feed-stuff or as manure. In general sesame meal is considered to be equal to cottonseed or soybean meal as a protein supplement for livestock and poultry. It is especially high in certain amino-acids such as methionine, which is low in soybean meal, and thus can be combined with it or similar meal to form a more balanced ration. An attempt to summarize the literature review on quality improvement of sesame was made to discuss the accomplishments of the past and perspectives in the future. The reviews on quality improvement of sesame were mainly discussed in connection with the cultural practices and genetic informations in current status. The emphasis focussed on environmental variation of quality in cultural practices, such as harvest time, variety by location, climatic condition, fertilizer application, and growth regulator treatment. On the genetic variation of quality, it was discussed on variety background, mutation breeding, correlations, and inheritance of quality related characteristics. It also was discussed on relationship between quality and plant traits, storage condition or period, and seed coat color. Moreover, current research status were reviewed on some minor elements such as sesamin, oxalic acid, and trypsin inhibitor. As a results of the review, the lack of an effort to quality improvement in each utilization area was indicated as a problem area. More active efforts for the improvement of quality were also insufficient to incorporate the available genes for quality in breeding method or collection and analysis of breeding materials. Therefore, researches in the future would be recommended to emphasize on these problem areas.

Korean vegetable dishes-Na mul are indigenous and popular foods for a long time, and have been eaten by not only the common people but also the royale people in the ordinary meal and customary affairs. Grains are principal item of diet for Koreans and additions of Na mul in diet provide the nutritional minerals and vitamins. Especially vegetable oils in seasoning played the important role in nutrition balance. This manuscript historically investigate the Korean vegetable dishes-especially Na mul, Seng chae, Ssam, and the vegetables, additional ingredients and seasonings. 1. Foreign vegetable were introduced very actively. As the result of it, the more variety of vegetables are available. 2. Vegetable oils such as sesame oil, perilla oil, roasted sesame seed and pine nuts, etc were widely used for seasonings. 3. Seng chae dishes had been prepared with more than two different kinds of vegetables. Seasonings are used from the various sources, and combination of ingredients and development of condiments are expected to research further. 4. Ssam foods basically used uncooked vegetables, but steaming and boiling are also common methods.
