Yeolgujatang is excellent in nutrition, except for calcium and vitaminC.
The effects of Japanese apricot(Prunus mume Sieb. et Zucc.) flesh on baking properties of white breads were investigated by evaluation of specific loaf volume, pH, acidity, rheological property, color and sensory quality. Bread was processed by adding 4.7%, 9.4%, 14.1% and 18.8% of Japanese apricot flesh to basic formulation. The compositions of Japanese apricot flesh were 88.19% moisture, 0.45% crude ash, 4.10% dietary fiber, 4.04% citric acid and 0.41% total sugars. The specific loaf volume of the breads was decreased from 3.274mL/g to 1.857mL/g as Japanese apricot flesh contents increased from 0% to 18.8%. The pH of the breads decreased but the acidity of those increased as the percentage of Japanese apricot flesh to wheat flour increased. Lightness(L value) of the breads decreased by the addition of Japanese apricot flesh, while yellowness(b value) and redness(a value) increased. Texture measurement showed that springiness, cohesiveness and resilience decreased with increase of Japanese apricot flesh contents. While, hardness, gumminess and chewiness were the lowest in the bread with 9.4% Japanese apricot flesh, and increased in the bread with 4.7%, 14.1% and 18.8% Japanese apricot flesh contents. In sensory evaluation, the highest sensory scores for flavor, taste, aftertaste and overall acceptability were obtained when Japanese apricot flesh content was 4.7%, and softness and chewiness was the best when 9.4% of Japanese apricot flesh was added. The moisture content of the breads containing Japanese apricot flesh was higher than that of the control to add no flesh during storage at 25℃. Based on physical, rheological and sensory evaluation, addition of 4.7~9.4% Japanese apricot flesh suggested to be acceptable for processing bread.
The object of this study was to investigate the relationship between the eating habits of high(4th, 5th, 6th) grade elementary school students and parental behavior characteristics(affection, rational guidance, overprotect and neglect). The parenting behavior scale and demographic variables, eating habits and food frequency were administered to the subjects. In this investigation, the subjects were 396 boys and 337 girls in Chunju city in Korea, 50.1% of the mothers was in the age from 35 to 39 years and 57.8% of the mother had an occupation. Data were analyzed by using a SPSS PS package. Significant differences and correlation among variables were determined by the frequency, 2-test and pearson's correlation coefficient. Eating habits was significantly influenced by mother's employment status, but was not affected by the levels of mother's education and income. Parental behavior characteristics was significantly related to the children's snacks habits(p〈0.05, p〈0.01), but have no connection with dietary habits and the eating out. The survey revealed higher percentage of the children who had taken affectionate, reasonable and positively reinforced child care, answered they enjoy meals and the other groups answered they did not. Also frequency of having soup, green vegetables, fruits, dairy products had positive relationship with affective, reasonable rearing attitude, but negative relationship with neglective rearing attitude. And the survey showed children who were reared in overprotect had chocolate, candy and the like in large quantities.
This study was conducted to investigate the properties of wet noodle when different concentrations of Prunus mume juice were added to the wheat flour. The characteristics of wet noodle including cooking properties, color, mechanical texture properties, and sensory quality were determined. The compositions of Prunus mume were 88.19% moisture, 0.45% crude ash, 4.04% citric acid and 0.41% total sugars. The pH of Prunus mume was 2.76. The moisture absorption rate, weight, volume and turbidity of cooked noodles added with Prunus mume juice were lower than reference sample. When the amount of Prunus mume juice increased, the Hunter L(brightness) value, a(redness) value of cooked noodles decreased but b(yellowness) value increased. Instrumental rheological characteristics of wet noodle containing Prunus mume juice were measured with a texture analyzer. The hardness, adhesiveness, cohesiveness, springiness and gumminess of wet noodle with 20% Prunus mume juice were higher than others. However, the hardness of cooked noodle decreased with the increase in the amount of Prunus mume juice into noodle. The adhesiveness, cohesiveness, springiness and gumminess of cooked noodles added with Prunus mume juice were higher than reference sample. The results of sensory evaluation of cooked noodles containing Prunus mume juice indicated that the appearance, color, taste and chewiness of the cooked noodle with 10% Prunus mume juice showed the higher preference than others. Based on cooking properties, rheological and sensory evaluation, addition of 10% Prunus mume juice suggested to be acceptable for processing wet noodle.
The Chosun Dynasty in the 18th century was a period of revival for science, art, and culture, bringing about Silhak(practical science), a new trend in the history of Chosun thoughts. In the history of fine arts, realistic landscape paintings and genre paintings were popular as realism became prevalent. From the aspect of food culture, in particular, the luxurious and elegant Korean-styled food culture was completed during this period. Iwanwasuseoksihoedo was painted by Jeong Hwang (1735-1800) in 1789, depicting a banquet on an elder's 60th birthday. It is classified as a genre painting in the late Chosun Period but it contains things that comes into our heart, which are white porcelain with blue celadon pictures, white porcelain bowls, busy atmosphere of a banqueting house where food is being carried in a hurry and elders' serene appearance. All these things show the abundance of life, the room and comfort of old ages, and the beauty and relish of life in the well-arranged living ground. Hoehonyedo was painted on an elder's 60th marriage anniversary by an unknown artist presumably in the 18th century is a painting as realistic as a documentary photograph. The work gives viewers pleasure and comfort because it describes not a mighty clan but the superb later years of an official who had lived right and upright life. In the aspect of food culture, it displays the food culture of the splendid sixtieth marriage anniversary of a Korean official through noble etiquette among family members, seat planning, unique table culture and high quality tableware including white porcelain with celadon pictures and pure white porcelain.
납과 산수유 열수 추출물을 6주간 급여하여 사육한 흰쥐의 식이섭취량, 음용수 섭취량, 체중증가량과 식이효율에서 흰쥐의 평균 체중 증가량과 식이섭취량은 정상군에 비하여 납 단독 급여군이 낮은 증가를 보였다. 간 장기 조직의 중량은 납 단독 급여군이 정상군에 비하여 증가하였다. 납 해독에 미치는 영향은 각 장기 조직에서 정상군과 산수유 급여군은 납 단독 급여군에 비하여 유의적으로 낮은 증가를 보였다. 반면에 납과 산수유 병합급여군은 정상군에 가깝게 회복되어 산수유가 어느 정도 조직을 보호하는 것으로 생각된다. 혈청 중의 AST와 ALT 활성은 정상군에 비하여 납 단독 투여군이 유의적으로 증가되었으며, 산수유 추출물 급여군은 억제되었다.
총각김치의 pH는 20℃ 24시간 발효/-1℃ 저장조합의 경우 다른 조합에 비하여 발효 초기에 크게 낮아졌지만 첨가한 젓갈중의 단백질에 의한 완충작용에 의해 pH 변화는 크지 않았다. 산도도 발효온도가 높아짐에 따라 더 크게 증가하였고 초기 1주일 동안의 산도는 배추김치의 산도보다 낮았으나 그 이후에는 더 높은 산도를 보였는데 이는 총각김치에 첨가한 찹쌀풀에 의해 산도가 증가했기 때문이다. 특히 총각김치는 찹쌀풀을 많이 첨가할수록 총각김치의 발효 후기의 산도가 높아진다. 조직감에서 puncture force는 발효 8주 후까지 서서히 감소하다가 그 이후에는 거의 변화가 없었으며 무발효/-1℃ 저장 조합의 경우에 가장 높은 값을 나타냈다. 관능평가의 경우 탄산미와 신맛은 20℃ 24시간 발효/-1℃ 저장 조합에서 가장 높았고 무발효/-1℃ 저장 조합에서는 풋내와 같은 바람직하지 못한 풍미를 나타냈다. 경도는 발효온도가 높을수록 낮은 것으로 나타났고 5℃ 3일 또는 6일 발효/-1℃ 저장조합이 가장 적당한 경도를 나타냈다. 외관은 초기에 발효가 진행된 20℃ 24시간 발효/-1℃ 저장 조합이 가장 좋은 것으로 평가되었고 무발효/-1℃ 저장 조합이 가장 나쁜 것으로 평가되었다. 총기호도는 발효온도가 낮을 경우 매운맛이 너무 강하게 느껴졌고 발효온도가 높을 경우 발효가 진행됨에 따라 매운맛도 감소하고 총기호도가 크게 증가하였다. 총균수는 20℃ 24시간 발효/-1℃ 저장 조합의 경우 7일 후에 1.15times109, 5℃ 6일 발효/-1℃ 저장 조합의 경우 6일 후에, 5℃ 3일 발효/-1℃ 저장 조합의 경우 7일 후에 각각 최고치를 나타냈으며 그 이후에는 거의 비슷한 경향으로 감소하였다. 젖산균 수는 20℃ 24시간 발효/-1℃ 저장 조합의 경우 Leuconostoc spp. 와 Lactobacillus spp. 는 7일 후에 각각 1.18×109와 5.62×109으로 최고치를 나타냈다. 효모수는 발효온도에 관계없이 약간씩 증가하는 경향을 보였지만 배추김치에서 보다 훨씬 낮은 경향을 나타냈고 첨가된 찹쌀풀에 의해 당 함량이 높아져 미생물수가 배추김치에서 보다 더 크게 증가하였다.
This study was performed to study the removal efficiency of residual organophosphorus pesticides with process for making Perilla Jangachi. Two organophosphorus pesticides(chlorpyrifos-methyl and fenitrothion) were artificially attached to Perilla leaves. Then Perilla leaves were washed with detergent solution for 1minute and rinsed 2 times each for 1 minutes. After washing with neutral detergent solution, Perilla Jangachi was made with 2 steps of optimal condition. As a pretreatment, when soaked with 2% salt concentration solution for 42hours, the removal rate of residual pesticides was 81.75% of chlorpyrifos-methyl and 76.82% of fenitrothion. When Perilla leaves were steamed for 72 seconds after soaking, it became 88.94% and 82.19%, respectively. Finally, after making optimal Perilla Jangachi with 27% onion contents, removal rate was 89.12% of chlorpyrifos-methyl and 82.76% of fenitrothion. Consequently, it appeared that the process for making Perilla Jangachi effectively removed the residual pesticides of Perilla leaves.
This study was conducted to investigate the effect of physical properties and antioxidant activities of the beer made by Lycii fructus for development of functional beer.

L(lightness) value was not significant difference among beer, although a(redness) and b(yellowness) values were higher in Lycii fructus beer than those of the commercial beer. Total phenolic acid contents were 0.790 mg/mL in Lycii fructus beer and 0.603 mg/mL in commercial beer. Electron donatin ability was 93% in Lycii fructus beer and 87% in commercial beer. Lycii fructus beer showed higher SOD-liked activities than in the commercial beer. The relative antioxidant effects of the Lycii fructus beer showed 19% inhibitory effect on the peroxidation of egg yolk lecithin.
To evaluate the effect of cereal supplementation on children's iron nutritional status of Korean institutionalized was designed. Dietary survey was carried out methods of food weighting in the breakfast or/and dinner, and record interview in lunch (n=74). A nutritional intervention study was carried out through supplementing cereal for 4 weeks in 24 children of 1 institution from 4 to 12 years. The children received 3.6mg elemental Fe(as 100g cereal) per day. Blood samples were drawn before and after supplementation. Nutrients which children's intake was less than two-thirds of Korean RDA were Vit A, Vit B1, Vit B2, Ca and Fe. The mean daily intakes of iron were 5.1mg for male and 4.9mg for female and 52.3% for male and 45.4% for female of Korean RDA. The proportions of children with iron depletion assessed by TIBC(>360mg/dl) and serum ferritin(<20ng/ml) were 56.6% and 58.7%, respectively. The proportions of children with the iron deficient erythropoiesis assessed by serum iron(<70ml/dl), Hb(<12g/dl), and Hct(<36%) were 76.0%, 58.7%, and 64.0%, respectively. After cereal supplementation, in anemic children, levels of Hct(p<0.001), serum iron(p<0.001) and transferrin saturation(p<0.001) were significantly increased. The effect of cereal supplementation in children with iron deficient erythropoeisis was more effective to improve the iron nutritional status than children with iron depletion. It was concluded that cereal supplementation program in anemic children was also effective to improve iron nutritional status.
The objective of this study is to develope natural and economical Naengmyun broth using stock prepared with chicken heads. Proper mixing ratio of chicken head stock and chicken breast broth was determined through the sensory evaluation. In order to find out the attributes of chicken head-chicken breast broth(CH-CB broth), chicken breast broth and beef brisket(BB) broth were mixed to the chicken head stock and compared the preference and chemical elements between the broths were compared. The appropriate mixing ratio for reinforcing the meat broth and savory flavor, of was determined to 3:7(w:w). The comparison of CH-CB broth's and CH-BB broth's elements showed that the amount of crude protein and ash was the same and, in the case of crude lipid, CH-BB broth had 0.01% more than CH-CB broth. In the case of the total amount of free amino acids, CH-CB broth had 1.6 times more than CH-BB broth. A survey with 50 consumers showed that was prefered between CH-CB broth and CH-BB broth. CH-CB broth with significance.
Male rats were fed a purified diet containing one of 3 experimental diets, gelatinized rice starch that was not modified physically (RC), gelatinized physically modified rice starch using ultrasonic homogenizer(RU), gelatinized physically modified rice starch using hydroshear homogenizer(RH) during 28 days. RC was used as the rice starch control. Feeding a physically modified rice starch (RU) caused an increase in liver weight and RH increased RNA and protein contents in kidney significantly although there were no differences in food intakes compared to feeding a RC diet. The wet weight of liver, kidney and heart were higher in RU. The wet weights of fecal output of the rats fed RH was greater than in rice control group. The gut transit time was longer in the rats fed RH than in the rice control group significantly. Serum GOT, GPT, total bilirubin concentration were tended to be lower and blood urea nitrogen was significantly lower in RH group. The maturation index of kidney was higher in RU than in RC. These results suggest that physically modified rice starch improved growth performance and physiological functions in organs of growing rats.
이상으로 한국의 채소음식에 대한 시대적인 변화 경향과 최근의 채소 섭취량 및 섭취형태 변화 경향을 살펴본 결과를 요약하면 다음과 같다. 1. 부족국가시대와 고려시대를 거치면서 채소의 종류는 점차 다양해졌으며, 조선시대에는 거의 현재와 비슷한 채소를 이용하였다. 상고시대 이래 계속 섭취하고 있는 채소로는 마늘과 쑥이 있으며 삼국 및 통일신라시대 이후 현재까지 계속 섭취하고 있는 채소는 가지, 오이, 상추가 고려시대 이후로는 죽순, 토란, 우엉, 무, 순무, 파, 부추, 미나리, 배추, 아욱, 시금치, 쑥갓 등이 조선시대 이후 현재까지 계속 섭취하고 있는 채소는 고추, 호박, 토마토, 캐비지, 셀러리, 케일, 순무(turnip), 근대(beet), 등이 있다. 한편, 과거에는 섭취했으나 현재는 섭취하지 않는 채소로는 박과 마, 순채 등과 각종 식용야생초들이 있다. 2. 한국인의 채소 공급량은 일인당 연간 232.2kg으로 나타났고 이러한 양은 이러한 양은 전세계의 평균 공급량인 101.9kg과 비교해서 많은 편이며 아시아 지역에서 비교해 보면 중국(203.5kg)이나 일본(111.6kg) 보다는 많은 양이었다. 3. 채소섭취량은 1970년 이후에 뚜렷한 증가가 나타났으며 1990년에 201.1kg으로 가장 많았고 그 이후 감소하여 2000년에 다시 증가하는 경향을 보이고 있다. 일본의 경우 1965년 이후 큰 변화없이 110-120kg 수준을 공급하고 있으며 중국의 경우에는 1995년 이후에 급속한 증가를 보이고 있다. 미국은 채소류의 공급이 꾸준히 증가하고 있는 나라로 나타났다. 4. 한국인이 가장 많이 섭취하고 있는 채소는 마늘, 파 등의 양념류와 배추김치, 무, 양파, 당근 등으로 종류가 매우 제한적으로 나타났다. 조사된 114종 가운데 섭취한 채소의 종류는 모두 72종으로 나타났으며 남자의 경우 1인 1일 섭취량이 가장 많은 채소는 배추김치였고, 그 다음으로 무, 양파, 파, 깍두기, 감자, 배추, 시금치, 애호박 등의 순서로 나타났다. 여자의 경우도 남자와 같은 경향이었으나 애호박이 다소비식품 내에 포함되지 않았다. 5. 구황식품과 부식으로 이용되었던 산나물과 야생식물의 이용은 현재 거의 사라진 반면 새로운 외래채소와 허브류의 도입은 급증하고 있으며, 채소를 섭취하는 방법도 다양해지고 있는 것으로 나타났다. 전통적인 나물에 대한 기호도는 낮아지는 반면 다양한 채소를 이용한 쌈싸기와 녹즙, 생식등이 상업화되었으며, 채소전문식당이 나타나고 있다. 또한 여러 형태의 채식주의도 나타나서 채식문화가 다양해짐을 보여주고 있다. 앞으로 채소 음식의 소비는 더욱 다양해질 것으로 보이며 따라서 우리가 과거에 섭취했던 산나물들의 효능과 함께 우리나라 전통 채소 음식의 조리방법에 대한 연구 및 보급 방안에 대한 연구가 필요한 것으로 보이며 변화하고 있는 채소의 생산과 소비 현황에 대한 보다 정확한 통계자료의 수집이 시급한 것으로 보인다.
