The purpose of this study was to examine height, weight, chest circumference, sitting height, hemato logical status, eating behaviors and nutrient intakes for primary school children in Gwangju. The subjects consisted of 101 boys and 109 girls aged
years old. There were significant differences in the height, weight, chest circumference, sitting height between the boys and girls. Hct, WBC, RBC, Hb, serum GOT, GPT and cholesterol were measured. With regard to meal regularity, 47.4% of the subjects has been 'regular'. With regard to meal volume, 15.8% of the subjects has been 'heavy'. With regard to meal balance, 44.7% of the subjects has been 'no'. The study also found that 63.4% of the subjects skipped breakfast, liked western food. Their dietary intakes were assesed for 1 day by means of 24 hours dietary recall method. The mean energy intakes of the subjects were 1,663kcal for boys and 1,427kcal for girls. The subjects for boys(girls) consumed 58(52)g protein, 43(60)g lipid, 4.8(6.5)g fiber, 470(514)mg calcium, 896(824)mg phosphorous, 9.6(16.4)mg iron, 3,301(3,468)mg sodium, 2,169(2,192)mg potassium, 388(466)RE retinol, 1.1(0.9)mg thiamin, 1.1(2.2)mg riboflavin, 12.2(26.3)NE niacin, 146(99)mg ascorbic acid and 251(159)mg cholesterol respectively. Energy, protein, calcium, iron and retinol intakes were lower than the Korean RDA. The intakes of fat, fiber, calcium, iron, sodium, retinol, riboflavin and niacin of the boys were significantly lower than those of the girls. There were positive correlations between meal time and protein intake or fat intake of fiber intake or iron intake or retinol intake : negative correlations between meal time and sodium intake : negative correlations between saltiness and cholesterol intake : positive correlations between use of perilla seeds and riboflavin intake or niacin intake : negative correlations between energy intake or carbohydrate intake or phosphorous intake : negative correlations between frequency of eating-out and protein intake or fat intake or fiber intake or iron intake or retinol intake or thiamin intake or riboflavin intake or niacin intake.

An attempt was made in this study to analyze volatile flavor components of A. macrocephala Koidz. and A. lanacea DC. (Atractylodes japonica Koidzumi). Essential oils in A. macrocephala Koidz. and. A. lanacea DC. were isolated by a simultaneous steam distillation and extraction(SDE) method using n-pentane/diethy ether as solvent. A total of 30 and 28 components were identified by GC/MS from the essential oils of A. macrocephala Koidz. (18 hydrocarbons. 2 carbonyls, 5 alcohols, 5 esters) and A. lanacea DC.(14 hydrocarbons, 6 carbonyls, 4 alcohols, 3 esters, 1 acids), respectively. The major volatile flavor components in A. macrocephala Koidz. and A. lanacea DC. were furanodiene(27.9%, 15.7%),
-cyperone(8.1%. 22.5% ), alloaromadendrene(2.9%, 4.7% ), (1,1-biphenyl)-4-carbon aldehyde 0%, 8.7% ) were found, respectively. Ten components including limonene, p-cymene, p-hymen-8-ol, (1,1-biphenyl)-4-carbox aldehyde were identified in A. lanacea DC, but not in A. macrocephala Koidz. and eight components including
-himahalene. germacrene B were and identified in A. macrocephala Koidz. but not in A. lanacea DC.
Volatile Flavor Components of Cultivated Radish (Raphanus sativus L.) Sprout
The Korean Journal of Food And Nutrition, volume 14, issue 1, 2001, Pages 20~27
The consumption of radish ( Rhaphanus sativus L.) sprout, which is Cruciferae family, is increasing because of its pungent flavor and taste. Its volatile components were analyzed by SDE (simultaneous steam distillation & extraction) method and P&T(purge & cryogenic trapping) method. As a solvent, diethyl ether and diethyl ether : pentane mixture(2:1, v/v) were used in SDE method, and diethyl ether in P&T method. Analyzing by GC and GC-MS, the major component was sulfur compounds (19 species, peak area 76.6%) with diethyl ether, sulfur compounds(15. 44.0%) and hydrocarbons(23, 23.8%) with diethyl ether-pentane mixture in SDE method. Also, hydrocarbons(25, 84.1% ) was major component in P& T method. The major volatile component of fresh radish sprout were n-heptane, methyl pentane and that of boiled radish sprout were 4-methylthio-3-butenyl isothiocyanate, methyl mercaptane, 2,3-dimethyl disulfide. Low molecular volatile components were detected more by P& T method, but types and relative quantities of volatile components were measured less comparing to SDE method.

The Korean Journal of Food And Nutrition, volume 14, issue 1, 2001, Pages 28~33
During storage of 45°Bx cloudy and 72°Bx clear apple juice concentrates for up to 16 weeks at 4
respectively, the changes of viable microbial counts, physicochemical properties were investigated and the correlation between the physicochemical properties were determined. During storage for up to 16 weeks, any viable microbes were not found in 45°Bx cloudy apple juice concentrate stored at -3 and -15
and in 72° Bx clear stored at all three temperature. There were little change in pH and tillable acidity except 45°Bx cloudy apple juice concentrate stored at -4
. As longer storage time and higher storage temperature, was shown higher redness of color(a value) and alcohol soluble color(ASC) in common. Vitamin C contents were more rapid decreased proportionally to time and temperature of storage. The high correlation coefficients were shown of 0.957∼0.967 between redness and ASC and -0.936∼ -0.864 between redness and vitamin C contents of apple juice concentrate during storage.
Influence of Green Tea Powder on the Physical Properties of the Bread Flour and Dough Rheology of White Pan Bread
The Korean Journal of Food And Nutrition, volume 14, issue 1, 2001, Pages 34~39
The purpose of this study was to examine physical properties of the addition of green tea powder on bread flour and dough rheology of white pan bread. Three levels(0.1, 0.5 and 1.0% ) of each green tea powder with bread flour were tested for their effects in dough mixing using rapid disco analyzer, alveogram and farinogram. Addition of green tea powder tended to reduce initial pasting temperature and increase peak viscosity, break down and set back. L(extensibility) and G(swelling index) value in alveogram showed decrement with increasing green tea powder. These meant that the volume of white pan bread would show same tendency. The use of green tea powder increased consistency and water absorption of the bread flour but decreased development time, salability and degree of softening on farinogram. White pan bread with green tea powder had higher value of hardness and springness than without it. Sensory evaluation determined that the white pan bread with 0.5% green tea powder had the highest score.
Effects of Various Emulsifiers on the Quality of Waxy Rice Cake
The Korean Journal of Food And Nutrition, volume 14, issue 1, 2001, Pages 40~45
This study was conducted to investigate the effects of various emulsifiers on the quality of the waxy rice cake. Falling numbers of the waxy rice flour with monoglyceride, lecithin and control were not significantly different, but with sugar esther 0.5% and 1% showed higher value as 88.4 and 81 than control Initial pasting temperature of the waxy rice flour was 66.78
and others were 66.45 ∼ 67.05
by adding 0.5%, 1% of emulsifiers such as monoglyceride, lecithin, sugar esther. Waxy rice flour with 1% sugar ester showed the highest peak viscosity as like as falling number. Waxy rice cake wish various emulsifiers showed tendency to be slowly firming rate as compared with control. In all case, waxy rice flour with sugar ester 1% was considered to be more effective to the decrease of firming rate. Waxy rice flour with lecithin showed worse visual color than others and sugar ester provided best visual and sensory quality. After 5 days cold storage, waxy rice flour with sugar ester 1%\`s Aw was 0.875 and control\`s 0.911. These results suggested that water holding capacity of sugar ester was the best during storage.
