In this treatise, we investigated the Korean literature of main dishes before the 17th century : ${\ulcorner}Sangayorock{\lrcorner}$, ${\ulcorner}Sasichanyocho{\lrcorner}$, ${\ulcorner}Soowonjabbang{\lrcorner}$, ${\ulcorner}Yongjechongwha{\lrcorner}$, ${\ulcorner}Dongyoebogam{\lrcorner}$, ${\ulcorner}Domoondaejak{\lrcorner}$, ${\ulcorner}Geebongyouseul{\lrcorner}$, ${\ulcorner}New-Guwhangchalyo{\lrcorner}$, ${\ulcorner}Eumshickdimibang{\lrcorner}$,, ${\ulcorner}joobangmoon{\lrcorner}$, and ${\ulcorner}Yorock{\lrcorner}$. Main dishes were classified 19 kinds of rice, 64 kinds of gruel, 6 kinds of thin gruel, 1 kind of Moori, 1 kind of rice-cake soup, 37 kinds of noodles and 20 kinds of dumpling. Rice varieties were brown rice, rice, hulled rice, millet rice, foxtail millet rice, barley rice, sesame rice and flax seed rice. Gruel ingredients were cereal, beans, vegetables, nuts or seeds, medical plants or hardy wild plants, poultry, pork's kidney, dog's liver or oyster, clam and/or milk Rice-cake soup was 'Tangbyun' in ${\ulcorner}Domoondaejak{\lrcorner}$. Noodles were divided by main flours: wheat flour, buckwheat flour, mung bean flour and other flours. Noodles were made by pressing or cutting method. Pressing method used a mold with a hole. The husk of dumpling was made by wheat flour, buckwheat flour, mixed flour of wheat and buckwheat, sliced fish or meat, and/or a gray mullet. Another special method was 'Sangwha' made by fermentation. Bun stuffing of dumpling used fishes, meat, vegetables, beans, flours and seasonings. Cooking methods of dumpling were boiling, baking, steaming and pan-frying. From this investigation of the Korean main dishes described in the Korean literature before the 17th century, we expect to develop useful recipes for those who are concerned about health and want longevity, and thereby to advance the Korean food culture.

A strain of yeast (Candida guilliermondii KFCC 35120) was cultivated by using the soybean whey with supplement of blackstrap molasses (4%) and ammonium acetate (0.5%). By the cultivation continued for 48 hours, 8.1g of dry cell was produced. The cell was consisted of carbohydrate 39.3%, protein 40.5%, lipid 3.9%, nucleic acid 9% and ashes 6%. The protein was analyzed to contain 18% of glutamic acid and 10% of lysine. Other amino acids showed a content near that of FAO reference protein except Methionine. Total lipid content was varied by nutritional condition especially by the kind of carbon source, however it showed a content 1.7 to 2.5 times higher than that of Saccaromyccs cerevisiae. The lipid contain 48% of oleic acid, 17% linoleic acid and 4% linolenic acid. The content of linoleic and lonolenic acid was higher than that of S.cerevisiae by 9 and 24 times, respectively.

Excavated textiles provide very important research data on the costume culture of the Joseon dynasty. In particular, dyed textiles are indispensable for textile conservation research and for restoration of remains as well as for general costume culture research. Unfortunately, a prolonged burial environment causes the colors to change and gradually fade after excavation. Therefore, it is very difficult to identify the original color. In this study, natural dyed samples of red, yellow, purple and blue were prepared and analyzed using HPLC-PDA. Dyes of colorants extracted from excavated textile remains were analyzed by HPLC. In addition, mordants were analyzed using (SEM-EDX) in order to estimate the original color. The 16~17th Century's three samples were analyzed, sample 1, and 2 from Eunjin Song's Song Mun-Chang excavated at the Songchon-dong in Daejeon, and sample 3 from Yeosan Song's Song, Hee-Jong excavated at the Mokdal-dong in Daejeon. From the HPLC results, alizarin, purpurin, and indigo were detected on sample 1, alizarin and purpurin on sample 2, ellagic acid and indigo on sample 3. Therefore they were dyed with madder and indigo (sample 1), madder (sample2), pomagranted and indigo (sample 3). Al mordant was identified on three samples.

Two different methods (Sieve shaker, Elzone particle size analyzer) were used to investigate rice flour particle size obtained by various milling method. Results of Elzone particle size analyzer were more effective than Sieve shaker in determining particle size, and the distribution of particle size of rice flours was affected by the type of the milling methods used. A rice flour, prepared in a Pin mill had a particle size range of $60{\sim}500$ mesh, and 30.38% of the sample was in the particle size range $200{\sim}270$ mesh. A rice flour, prepared in a Colloid mill had a particle size range of $40{\sim}500$ mesh and more of flour particles appeared in the range $140{\sim}200$ mesh than any other particle size. A rice flour, prepared in a Micro mill had a particle size range of $140{\sim}500$ mesh, and 41.62% of the sample was in the particle size range over 500 mesh. A rife flour, prepared in a Jet mill had a finer flour particle size was over the particle size range 500 mesh. The finer rice flour gave the highest L value and the lowest a value. The wet-milled flour particles were observed as a cluster of starch granules and the particles of rice flour (dry-milling) were observed as fragment of rice grains. Scanning Electron Photomicrographs revealed that visual differences in structure between milling methods, and similar results with Elzone particle size analyzer method in particle size.

Rice flour obtained by four different milling methods, Pin mill. Colloid mill, Micro mill, and Jet mill, were used to investigate physico-chemical properties and product. Crude fat, ash, and protein contents of rice flours between different milling methods were similar. Blue value, amylose content, and damaged starch which related to properties of rice flour were reduced in the order that of Jet mill, Micro mill, Colloid mill, and Pin mill. Water absorption index, water solubility index, and water retention capacity increased as damaged starch increased. Hardness of gel(15%) is the highest value for Pin mill. The finer granules (Jet mill) had lower gelatinization onset(To) and peak(Tp) than any other rice flours. Those result are simillar with amylogram properties. Enthalpy of gelatinization increased as damaged starch increased. Jet mill had the highest score (p<0.05) of overall test in sensory evaluation and good paste properties.

The effects of lactic acid bacteria on the chemical and microbial changes of fermented kimchi at various temperatures were studied. Kimchi was homogenized and was sterilized by ultra violet, then Lactobacillus plantarum, Leuconostoc mesenteroides, Pediococcus acidilactici, Lactobacillus brevis and the mixture of there bacteria inoculated on sterilized kimchi, respectively. The measurement of pH and total acidity, quantitative analysis of volatile organic acids and nonvolatile organic acids by gas chromatography were investigated while inoculated kimchi were fermented at $30^{\circ}C$, $21^{\circ}C$, $14^{\circ}C$ and $7^{\circ}C$. Sample I (original kimchi homogenate), Sample III (inoculated with Leuconostoc mesenteroides) and Sample Ⅵ (inoculated with mixed lactic acid bacteria) were alike in that changes of pH and total acidity and especially, these phenomena were prominent at $14^{\circ}C$. Formic, acetic and heptenoic acid as volatile organic acid were detected by GC, and these acids formed mainly by Leuconostoc mesenteroides and lactobacillus brevis. Sample III was more higher content than other samples at $14^{\circ}C$. As nonvolatile organic acid, lactic acid in all samples, citric acid in sample III at $21^{\circ}C$and $14^{\circ}C$, succinic acid in sample I at $30^{\circ}C$, $21^{\circ}C$, $14^{\circ}C$ and sample V at $30^{\circ}C$ were detected by GC.

The lipid and fatty acid composition of various poultry eggs were examined after extracting yolk oils from the eggs of caged hen, open barn-reared hen, mallard, and muscovy duck. Total lipid content in 100 g of each edible portion was the highest in muscovy duck egg followed by open barn-reared hen, mallard, caged hen, and natural hen eggs. The triglyceride contents in the egg were in the order of caged hen, open barn-reared hen, natural hen, mallard, and muscovy duck. The cholesterol contents in total lipid were the highest in caged hen and muscovy duck eggs(4.5%), and the lowest in mallard(3.3%). Caged hen eggs had higher neutral lipid ratio among total lipid, but had lower ratio of glycolipid and phospholipid compared with those of the open barn-reared hens. For fatty acid composition, linoleic acid was the highest in the muscovy and linolenic acid was the highest in open barn-reared hen eggs. The contents of arachidonic acid and Eicosapentaenoic acid(EPA) were the highest in muscovy eggs. On the other hand, the content of Docosahexaenoic acid(DHA) was the highest in muscovy duck eggs.

Soy sauce was prepared with the addition of Gorosoe and Kojesu saps instead of tap water to make ordinary soy sauce, respectively. The changes of free sugar, organic acid, mineral, amino acid and nucleotides and other compounds during the fermentation of soy sauce were assessed. The free sugar were found to be fructose, glucose, galactose and sucrose in soy sauce of saps but sucrose was not detected in ordinary soy sauce. Galactose contents were dominant free sugar in all samples. The contents of butyric acid were dominant among 7 kinds of organic acid while fumaric acid was trace amount during the fermentation of soy sauce. The contents of potassium and phosphorus among 13 kinds of minerals were dominant during the fermentation of soy sauce. In the amino acid composition of soy sauce, dominant amino acid was glutamic acid(185.6${\pm}$1.0 mg/100 ml above), but proline and arginine were not detected. AMP detected above 7.5${\pm}$O.2 ${\mu}$mol/100 ml was dominant while inosine was not detected during the fermentation of soy sauce. The results of sensory evaluation in the fermented soy sauce of Gorosoe was 'liked more' than that of soy sauce of Kojesu and control.

There were fifty two kinds of fermented soybean sauce before 17th century thirteen recorded in ${\ulcorner}$Sangayorock${\lrcorner}$, two in ${\ulcorner}$Sasichanyo${\lrcorner}$, one in ${\ulcorner}$Yongjechongwha${\lrcorner}$, nine in ${\ulcorner}$Soowonjabbang${\lrcorner}$, one in ${\ulcorner}$Domoondaejak${\lrcorner}$, six in ${\ulcorner}$Dongyoebogam${\lrcorner}$, four in ${\ulcorner}$Gushangchalyo${\lrcorner}$, five in ${\ulcorner}$Guhwangboyubang${\lrcorner}$, two in ${\ulcorner}$Yorock${\lrcorner}$, four in ${\ulcorner}$Chisengyoram${\lrcorner}$ and five in ${\ulcorner}$Joobangmoon${\lrcorner}$. These books had thing to know when making fermented soybean sauce like kinds of soybean sauce, how to make it, its ingredients and quantities to be used, how to make fermented soybean sauce in haste, and how to remake wrong made fermented soybean sauce, etc. Before 17th century, fermented soybean malt was divided into two kinds the only soybean malt and the mixed soybean malt that had bean, wheat, wheat flour and wheat bran. The bean only soybean malt was further divided into mashed soybean malt (Beans were steamed and mashed into past.) and unmashed soybean malt (Beans maintained their shape without being mashed.) while mashed soybean malts were made in Winger, in January of February, unmashed and mixed soybean malts were made in Summer, in July. When made fermented soybean sauce, mashed and unmashed soybean malts were used as they were and mixed soybean malt was dried and powdered for use. Fermented soybean sauce before 17th century could be classified by the features of soybean malts being used, Normal fermented soybean sauce was made from bean only soybean malts and other ingredients. Shi(시) was made from unmashed soybean malts, in which beans maintained their shape, and Gowhajang and Jeupjang were made from mixed soybean and wheat bran. Fermented soybean sauce was also made from old fermented soybean sauce, yeast. water leftover after boiling bean leaves, and soybean chaff without soybean malt. There were also side dish type soybean sauce like Kongjaban today and fish and meat sauce made from flesh ingredients. To make fermented soybean sauce in haste, the soybean sauce was heated. Beside there were how to maintain fermented soybean sauce and how to remake wrong made fermented soybean sauce.

The cooking quality of irradiated chestnut after longterm storage were evaluated. 1. Color degree and tannin content of irradiated chestnut were slightly increased with the storage, but there was a little difference according to the radiation dose after nine months storage. 2. The main component of free sugars in the irradiated chestnut were identified as sucrose, glucose, fructose and the amino acids of chestnut were identified in the decreasing order of glutamic acid, aspartic acid, leucine, arginine, glycine, alanine, serine, pheylalanine, threonine, valine, isoleucine, tyrosine, methionine and cystein. Free sugars and amino acids of 25 Krad irradiated group showed a little difference compared with those of control group after nine months storage. 3. The calorie of candied chestnut prepared from nine months stored was marked 199 Kcal/100g of edible parts compared with 159 Kcal of raw chestnut. 4. Texture and sensory evaluation of candied chestnut prepared from nine months stored were better in 20-25 Krad irradiated group than in control group.
