A Study on the Flavor Compounds of Dongchimi
Lee, Mae-Ry ; Lee, Hei-Soo ;
Korean journal of food and cookery science , volume 6, issue 1, 1990, Pages 1~8
To study the most optimum condition of Dongchimi, 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 were extracted by steam distillation In results, the most optimum conditions ware salt 2.4% fermented temperature
, 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.

Korean journal of food and cookery science , volume 6, issue 1, 1990, Pages 9~12
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 hexameta-phosphate(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.

Cowpea, mung bean, Kidney bean and red bean are simular properties. In order to elucidate the similarity among these four starches, some physicochemical properties of starches were compared. Water binding capacity of kidney bean and red bean (199%) starches are higher than mung bean and cowpea. The solubility, swlling power and optical transmittance of the four starches showed a similar pattern, but kidney bean and red bean starches had a lower swelling power than cowpea starches. Cowpea, mung bean, kidney bean and red bean starches had the blue value of 0.41, 0.47, 0.42 and 0.50, the alkali content of 8.4, 8.0, 4.13, 4.13, the amylose content of amylose of 30,000, 29,268, 52, 173 and 33, 611 and glucose unit per segment of amylopectin of 27.6, 26.8, 18.35 and 12.9 respectively. The results of X-ray diffraction studies showed A pattern for four starches.

As a series of investigation on the ex-N compounds, the amino acid composition of the naturally grown and cultured prawn meat extracts was analyzed according to the following extraction conditions: 70% ethyl alcohol extraction, alcohol treatment of the same concentration after hot water extraction for 30 min, and 5% TCA treatment. The Protein content and the level of pure protein was 22 .8% and 18.4% in naturally grown prawn muscle, and 21.8% and 15.3% in the cultured prawn muscle, respectively. None protein nitrogenous compounds of the extracts were 4.4% in the naturally grown prawn muscle and 6.5% in the cultured prawn muscle, respectively. According to the different extract condition, ex-N compounds and the amino acid composition and related compounds and the amino acid composition and related compounds showed high level from 5% trichloroacetic acid extraction. The content of ex-N compounds of the cultured prawn muscle was 1033.0mg%. whereas the content of amino acids and related compounds-N was 825.3mg%, nearly reached to 80% to the total extractive nitrogen. A common feature of the free amino acid composition in the extracts of the muscles of the naturally grown and cultured prawn was high contents of glycine, proline, taurine, alanine and hydroxyproline.

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 utilize their knowledge about foods in real dietary life, but also fell short of endeaver to do so. They chiefly made use of the cooking methods 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.

Consumption pattern of Ramyon by high school students at age of 16~20 years in Kangwondo area was surveyed by questionaire. About 74% among 754 students consumed Ramyon more than once per week. Most consumers eat Ramyon because of convenience for meal substitution. They consumed Ramyon at between meals and lunch at home. The advertisement had a strong effect on the selection of Ramyon. Consumers considered that taste of soup and texture of noodle are both important quality factor of Ramyon. In terms of the texture of cooked noodle, the most desirable was chewy and hard texture. The most undesirable was swollen and mushy texture. The most desirable and undesirable taste of soup were spicy and greasy taste, respectively. At present, no significant differences in consumption pattern between sex were observed in most cases.
