This study was conducted to standardize ingredient ratio and preparation method of mafor traditional special kimchies in kyungsang province, korea. There were about 35 varieties of special kimchi in Kyungsang province. Six varieties of them such as burdock kimchi, wild leek kimchi, green thread onion kimchi, perilla leaf kimchi, Godulbaegi(Korean wild lettuce) kimchi, and red pepper leaf kimchi were selected, because they tasted good and the physiological functions of their main ingredients were excellent. The ingredient ratios of the selected special kimchi were standardized through surveying hereditary preparation of some families in kyungsang province and using the literatures including cooking books. The standardized ingredient ratio of the burdock kimchi was 15.1 pickled anchovy juice, 6.8 red pepper powder, 5.7 garlic, 2.2 ginger, 18.0 rice flour paste, 13.5 green thread onion, and 1.2 sesame seed in proportion to 100 of burdock. The standardized preparation step of the selected special kimchies was similar except some preprocessing methods of main ingredients. The diagonally cut-up burdock ws usually parboiled or soaked in salted water, then it was mixed with the other ingredients. Wild leek and green thread onion were usually pickled with salt or pickled anchovy juice. Sometimes the green thread onion pickled was dried in the sun. General preprocessing of perilla leaf, Korean wild lettuce, and red pepper leaf was soaking them in salted water for about 5-10 days. Sometimes red pepper leaf was heated with steam and dried in the sun, then it was mixed with the other ingredients.

Dietary fiber(DF) content and their properties were analyzed in some common vegetables such as Squash(leaf), Water cress, Garland chrysanthemum, Leek and sweet potato(stem). DF was analyzed by the method of detergent fractionation. Values for neutral detergent fiber(NDF), acid detergent fiber(ADF), lignin, hemicellulose were obtained. NDF for most samples was $13.83%{\sim}24.31%$, ADF was $11.99%{\sim}21.03%$, lignin was around $0.56%{\sim}3.00%$, hemicellulose was about $1.33%{\sim}3.88%$, cellulose was $9.08%{\sim}14.87%$ except sweet potato(leaf) (20.47%). This paper describes two properties of the fiber-of commonly eaten vegetables ; water-holding capacity(WHC) and metal binding. The capacity of the acetone dried powder (ADP) to hold water was estimated. The WHC measurements differed from 7.49 per 9 of ADP for Water cress to 11.09 per 9 of ADP for Leek. The binding of Fe, Zn in NDF. ADF obtained from five fiber sources was examined under two pH conditions ; 1) pH2.1, 2) pH6.1. Fe, Zn binding increased with higher pH and differed from DF sources.

The effect of various levels of perilla seed powder on physicochemical, microbiological, and sensory characteristics of Puchukimchi during fermentation was investigated. Puchukimchi is a kind of korean kimchi made with Leek (Allium odorum L.). In a laboratory model of Puchukimchi made with various levels (0, 1, 2, 3, 5%) of perilla seed powder fermentated at 10$^{\circ}C$ up to 45 days. As a fermentation progressed, the initial high decrease in pH has been retarded in all the treatments, of which the delaying extent was noted from Puchukimchi made with perilla seed powder. The pH dropped with accumulation of total acidity. The total vitamin C content increased sharply at the palatable period of Puchukimchi during initial fermentation and then, especially from the 8th-day, gradually decreased later following sigmoidal changing pattern. And the total vitamin C content was the highest in the Puchukimchi made with 5% perilla seed powder. The lactic acid bacteria count increased remarkably and then decreased gradually after optimum ripening period, i.e., the palatable period of Puchukimchi during fermentation. During the early stage of fermentation, sensory evaluation showed the higher scores on the overall taste of Puchukimchi made with 3, 5% on the 2nd-day, 1, 2% on the 5th-day of fermentation. However, the trend of acceptability has been reversed by the Puchukimchi made with little amount of perilla seed powder, more notably 2% at the later stage of fermentation.

Melatonin, which is a hormone secreted from pineal gland of brain and known to prevent oxidative damages of various tissues, was analyzed in 26 domestic edible plants. For the preparation of melatonin fraction, 50% ethanol extract prepared from lyophilized plant powder was filtered and applied on TLC plate. Melatonin position on TLC developed with acetone was identified by fluorescence light and extracted with methanol. This methanolic fraction was injected into HPLC comprising ODS-A column, fluorescence detector, and mobile phase consisting of a mixture (30 : 70, v/v) of 70% ammonium acetate and methanol at a flow rate of 1.0 mL/min. Melatonin was identified at the retention time of 17 min. Results revealed that celery, leek, broccoli, and cauliflower had higher melatonin contents than others.

In this study, the kinds of Dog Meat Cooking, the frequency of them, the ingredients, and the variation of recipes written in the books from 1670 to 1943 in Korea were studied. 1. There were 14 Dog Meat recipes in the literature. And the number dishes is 50. Among these, Jeung (steaming in seasoning:(蒸) had the highest frequency, 20(40%), which has played a main role. Kaeng or Tang (soup:(羹,湯) has appeared 12 times (24%) and Eikin koki dasi chinun bup (steaming twice), Kujang(steaming with white onions:((狗醬) 4 times (8%), respectively. 2. The number of sesonings was 22, the major ones according to the frequencies were oil and soy sauce(34.7%), sesame-seed powder(32.6%), pepper(30.4%), vinegar(30.4%), soy sauce (23.9%), red pepper powder(21.7%(, sesame-seed oil(19.5%), Mancho powder(19.5%), and Chuncho powder(19.5%). 3. Five ingradients were found, among which onion was most widely used(28.2%), Parsley(17.3%), Kyeyun(8.6%), leek(2.1%), and walnut(2.1%) have also appeared.

The purpose of this paper is to examine the various kinds of recipes of pheasant through classical cookbooks written from 1670 to 1943 which are the basic materials to the meat cooking. The recipes of pheasant are found 39 times in the literature, which can be classified into eleven groups. Chronologically, the recipe of mandu (ravioli) was first appeared, and guk, tang (soup), kui (roasted), jang (salted meat), chim (steamed), po (dried meat), whe (raw meat), gijim (boiled in soy sauce), cho (sparkly heated in soy sauce and sugar), jolim (hard boiled in soy sauce), and jungol (meat with vegetable cooked in pan) followed in the records. Kui was the most popular one with the frequency of 43.6%, which proves that kui is the most suitable one for pheasant among all of recipes. Mandu and guk, tang were 10.2%, chim and po were found with the same rate of 7.7% and the next ones were jang, gijim, cho, and jungol with the rate of 2.6%. The recipes of pheasant were recorded much less than those of beef, chicken, pork, lamb, and dog meat. Particularly, in comparison with chicken belonging to fowls, the frequency of pheasant cooking did not reach even to one third of that. The Korean recipes of pheasant have been independently developed with originality, having nothing to do with the Chinese ones. The recipes of pheasant before the late 1800s have based on the strict recipe principles along with the spirit of art and sincerity, but they were deteriorated to simple and easy ones discarding principles. The main ingredient was the flesh of pheasant and the sub-ingredients such as flour, pinenut, buckwheat powder, and mushroom were included in common. In additon, oil, soy sauce, black pepper, and stone leek were frequently used as main seasonings.

This study examined the changes of side dishes in "Eumsikdimibang", "Gyuhapchongseo", "Chosunmusangsinsikyorijebub" over time. As food ingredients, seaweed, red pepper, salted fish, Korean hot pepper paste have been used in "Gyuhapchongseo". The use of cattle by parts, saltwater fish, Chinese cabbage, powdered red pepper, garlic have increased in"Chosunmusangsinsikyorijebub". Cooking techniques, such as the use of wheat flour, a double boiler by the use of steam, and boiling and then roasting cuisine were mostly used in"Eumsikdimibang", but reduced in"Gyuhapchongseo". In "Gyuhapchongseo", the cooking methods are primarily aimed at a positive visual effect, and slices of dried meat seasoned with spices have increased. In"Chosunmusangsinsikyorijebub", various Tang (Guk), the taste of food changed by controlling the gravy content (Gigimi, Chigye, Chorim), meat mixing oil, vegetable and mushroom together to cook and boiling down the main food ingredients to soak the seasoning were increased. Dog-meat steamed dish using the intestine of dog in "Eumsikdimibang" was changed to small intestine of cattle steamed dish in "Gyuhapchongseo". And seasoned dog meat with choncho in "Eumsikdimibang" influenced on beef tail soup with Korean hot pepper paste in "Gyuhapchongseo", and Yookgyejang soup using Korean hot pepper paste in"Chosunmusangsinsikyorijebub". In steamed young chicken, the stuffing such as soybean paste, choncho, welsh onion, leek and flour in "Eumsikdimibang" was changed to minced beef, welsh onion, dropwort and Shiitake mushroom in"Gyuhapchongseo". The steamed young chicken in "Chosunmusangsinsikyorijebub" with stuffing was added to chicken soup using glutinous rice, and ginseng powder. Now, the chicken soup was changed to Samgyetang with glutinous rice, and ginseng. In "Chosunmusangsinsikyorijebub", various vegetable dishes were cooked with beef.

Antioxidative activities (AA) of mustard leaf kimchi (MLK) by the addition of optional ingredients among selected minor materials were studied. In order to determine AA of MLK with different spices, the model systems of ground cooked beef with green onion, garlic, and red pepper powder were prepared and stored for 4 weeks at 4$^{\circ}C$. AA of red pepper added group was stronger than those of others. AA of red MLK was relatively higher than that of (green) MLK. For the enhancement of AA of MLK, another model systems were prepared with the selected antioxidative optional ingredients, which were bonnet bellflower root, leek, burdock, sea tangle, sea mustard, seastaghorn at the level of 2% or 4%. The extracts of water, 75% methanol and hexane of MLK, bonnet bellflower root added MLK, and seastaghorn added MLK had a considerable AA with the inhibition of peroxide formation during the autioxidation of linoleic acid mixtures in aqueous model systems at 37$^{\circ}C$. Therefore, AA was more effective in MLK containing specific optional ingredients than that of MLK alone significantly.

This study was performed to investigate the contaminated status of endocrine disruptor-suspected pesticides in agricultural products distributed in northern Seoul in 20l0. We analyzed 33 kinds of pesticides by multiresidue analysis method in 3,081 samples. Twelve pesticidcs were detected 600 times and violated 22 times from the agricultural products. The highest frequency of detection was procymidone and that of violation was endosulfan. The highest rates of detection divided violation times as diazinon. In agricultural products, 466 samples had pesticide residues and 22 samples violated the maximum residue limits (MRLs). Agricultural products were also classified by type and red pepper powder belonged to the others was the highest detection rate at 70.7%, fruiting vegetables 35.3%, tea leaves 23.6%, stalk and stem vegetables 21.2%, fruits 14.6% and leafy vegetables 11.2%. The rates of violation sample were stalk and stem vegetables 1.1%, leafy vegetables 1.0% and roots and tubers 0.4%. Leek was to be managed primarily because it had the high detection and violation ratio and was detected together several pesticides.
