Abstract
To study the most optimum condition of Dongohimi, the various Dongchimi distinct from the amount of salt, the temperature of fermentation and the ratio of radish to water were examed by sensory evaluation. Also, the content of volatile organic acids and nonvolatile organic acids were investigated by GC, the content of sulfur compounds by GC/MS. Volatile organic acids were identified with those butyl esters and nonvolatile organic acids were done with those TMS derivatives Sulfur compounds and those decomposed products extracted by steam distillation. In results, the most optimum conditions ware salt 2.4%, fermented temperature 4℃, ratio 1 : 1.5. Volatile organic acids detected were formic, acetic acid, and the amounts were effected by saltness. Nonvolatile organic acids detected were lactio, malio, fumario, tartario acid. Lactic acid was thought to effect overall eating quality. Sulfur compounds were almost the isothiocyanate groups in raw radish, which little in fermented Dongchimi.

Abstract
This study was carried out in order to investigate the physicochemical properties of isolated pectic substances from Citron, Satsuma mandarin, Marumero, and Natsudaidai. Among varieties, Citron had the highest value of isnoluble pectin and Marumero had the hightest ratio of soluble pection. The total pectin contents isolated by 2% Sodium hexametaphosphate (SHMP) varied in the range of 1.85%-2.63%. Anhydrogalacturonic acid (AUA) contents were 78.64% ∼89.14% and were lower than commercial pectin. Isolated pectin contained above 7% methoxyl content and above 50% esterification. The apparent molecular weight of commercial pectin and isolated pectin were 72,000 and 42,000∼46,000 respectively. Esterification and ester methoxyl content were the lowest and apparent molecular weight was the highest in Satsuma mandarin. Citron`s values were a little higher in esterification and ester methoxyl content and lower in apparent molecular weight than the others.

Abstract
A special form of questionaire was prepared and distributed to 502 housewives in seoul from Feb. 8th to 22nd in 1989. The results were as follows: In cooking methods, they tended to follow in the steps of their mother, and it took about half an hour or an hour to prepare a meal. They cooked fried foods once or twice a month. Whenever they fried foods they need new oil. Followings were details of cooking method mainly used by housewives. Fishes were tended to be roast, vegetables to be dressing and seasoning. Highly milled boiled rice was best preferred as the cheif food, and it was cooked by following procedure; First rice was washed, and steeped in water for the time being. Next, the water was poured out and water was filled again, then rice with the water was boiled. Fish Chige was cooked in the way that fish was put into the boiled soup. Fermented sao-bean paste Chige was cooked using water in which rice had been washed. Hard-boiled beef with soy sauce was made using the method that soy sauce was properly poured after beef was boiled. A Spinach was boiled shightly with salty water. In view of those results, there were many cases that housewives did not only ytilize their knowlege about foods in real dietary life, but also fell short of endeaver to do so. They chiefly made use of the cooking mehtods instructed from their mother or husband`s mother. In conclusion, in order to illuminate housewives to have an exact nutritional knowledge about foods and cooking methods getting out of the loss of nutritions, nutritional education program must be provided for housewives.
