  • 한약재인 당귀 분말을 첨가한 기능성 빵을 제조하기 위하여 당귀 분말을 $0{\sim}10%$ 첨가하여 제조한 식빵의 일반성분과 제빵품질 특성과 관능검사를 조사하였다. 일반성분의 수분, 조단백질, 조지방 및 조회분 함량은 모두 대조구가 낮게 나타났고, 당귀 분말 첨가량이 증가할수록 모두 증가하였다. pH는 대조구와 당귀 분말 첨가 시료 간에 유의적인 차이를 나타내지 않았다. 식빵 무게는 대조구가 가장 낮았고, 당귀 분말 첨가량이 증가할수록 증가 하였으며, 부피는 감소하였다. 빵 색도 측정 결과 crust와 crumb의 색도는 대조구보다 당귀 분말의 첨가량이 증가할수록 L값은 낮아졌으며, a값과 b값은 증가하였다. 조직감에서는 당귀 분말 첨가량이 증가할수록 경도(hardness), 점착성(gumminess), 씹힘성(chewiness)은 증가하였고, 부착성(adhesiveness), 탄력성(springiness)과 응집성(cohesiveness)은 감소하였다. Crumb softness 측정에서는 1일과 7일 경과 시 당귀 분말 2% 첨가구가 가장 높게 나타났고, 탄력성은 당귀 분말 5% 첨가구가 가장 낮게 나타났다. 빵의 저장중 수분활성도는 3일 경과 후 당귀 분말 2%와 3% 첨가구가 가장 높았으며, 7일후에는 모두 조금씩 감소하는 경향을 보였다. 관능 평가에서는 맛, 향미, 전체적인 선호도의 경우 당귀 분말 0.5%와 1% 첨가구가 가장 높게 나타났으며 당귀 분말 첨가량이 증가할수록 색, 외관, 입안에서 느낌, 질감에 대한 기호도는 점점 감소하였다. 이와 같은 결과로 생각할 때 당귀 분말을 $0.5%{\sim}1%$ 정도 첨가는 기능성 빵으로써의 개발 가능성이 있다고 판단되어진다.

  • 우유단백질과 검류의 혼합 첨가가 빵의 노화를 억제시키는데 사용될 수 있는지를 조사하기 위하여 이들 첨가한 밀가루의 amylogram, farinogram 그리고 extensogram을 측정하였다. 또한 우유단백질과 검류를 첨가한 반죽을 8주 동안 냉동 저장한 후 이 냉동반죽으로 식빵을 제조하고, 만든 당일과 $5^{\circ}C$에서 4일간 저장한 식빵의 수분함량 변화와 경도 변화를 측정하여 노화정도를 비교하였다. Amylogram 특성 중 우유단백질과 검류를 첨가한 밀가루의 호화 개시온도가 증가하였고 CA와 WA 첨가한 밀가루의 최고 점도가 대조구보다 낮았다. Farinogram 특성을 통해 우유단백질과 검류가 밀가루의 수분 흡수율을 증가시키는 것과 CA와 WA를 첨가할 경우 반죽 형성시간이 길어짐을 확인할 수 있었다. Extensogram 특성에서 밀가루의 신장도는 우유단백질과 검류를 첨가함으로써 낮아지는 현상을 보였다. 빵의 수분함량 변화를 살펴보면, 4일 저장기간 동안 모든 빵의 수분이 감소되는 것을 알 수 있었으며, 냉동저장 6주후부터는 대조구 빵의 수분함량이 우유단백질과 검류를 첨가한 빵보다 감소정도가 큰 것을 확인할 수 있었다. 빵의 경도 변화의 경우 또한 저장기간 동안 대조구 빵이 우유단백질과 검류를 첨가한 빵, 특히 CA와 WA를 첨가한 빵보다 높은 경도를 나타냈다. 이를 통해서 우유단백질과 검류를 첨가할 경우 반죽의 제빵 적성을 향상시켜주며 CA와 WA의 첨가는 빵의 노화를 지연시켜주는데 효과가 있는 것으로 생각된다.

  • To investigate the food choices and Dietary Preferences of College Women the number of dishes sold and the sales of the midmeal at the Student Cafeteria, Ewha Womans University were recorded for the fiscal year of 1974; and the observations were made on two consecutive days (June 3rd and 4th, 1974)on what a person has chosen which and how many dishes. The relationship between the number of the consecutive days and the number of foods chosen were treated as Chi square analysis. The results of the food choices and dietary preferences of College Women were as follows: 1. Breads and rice cakes, vegetable dishes, milk and milk products, rice dishes, soups, meat, fish, poultry and eggs, Kimchis and one dish meal were chosen highly; and beverages, stews, and soybeans and soybean products were chosen negligibly. 2. One dish meals, vegetable dishes, meat, fish, poultry and eggs, milk and milk products showed the highest sales volume during the year; rice dishes, breads and rice cakes were the second highest in sales amount; fried foods, snacks and Kimchis showed the range of $3{\sim}6%$ of the total sales; and the beverages, stews, soybean and soybean products were the lowest in sales amount. 3. Seasonal differences were noticed on some dishes. Breads add rice cakes, milk and milk products showed the high selections from March to November and the low, during December to February. Stews, Kimchis, beverages were kept low except sudden rise on February. One dish meal and rice dishes showed almost same level during the year but on February the slight increase were noticed; even level were kept on meat group except the increase to $13{\sim}16%$ on July and December. Fried foods were kept on similar level during the year except the increase on June. Snacks and fruits showed low selections on March, April, November and December and higher at summer. Vegetables, soups, soybean and soybean products showed no different fluctuations in selections during the year. 4. Rolls, salads, milk, hamburgers, fried vegetables, rice with mired vegetables(Bi-bim-bab), and Nang-myun were the single dishes chosen most frequently. 5. There is significant relationship at 0.05 level between the consecutive days and the number of foods chosen. It is concluded that about 50% of the population has taken one item of dishes. The popular combinations were one dish meal and soup or Kimchi; noodles and salads or fried vegetables. It is suggested to set up choice menus with the daily variations, cyclical variations and with the invariable ones; and to recommend one dish meal, breads, partial meals for school lunch; and to study to improve one dish meal, vegetable dishes and fried foods, which are new and inexpensive products. It is also suggested that the feeding of the college students should have to lead the people to the goal that the nutrition education is desired.

  • The quality of frozen bread dough made with the milk proteins casein (C), whey (W), and the gums sodium alginate (A) and ${\kappa}$-carrageenan (K), was investigated to develop methods to suppress the deterioration of the frozen dough quality. The control had a lower dough volume than dough with additives during freeze-thaw cycles. In bread stored at $5^{\circ}C$, the moisture content of bread prepared with whey plus sodium alginate (WA) decreased less than that of the control. The control also had a lower specific loaf volume than breads made with added milk proteins and gums. The hardness of the control bread and bread made with casein plus sodium alginate (CA) and whey plus ${\kappa}$-carrageenan (WK) increased during freeze-thaw cycles, although that of the control increased more than the others. There was no significant difference in sensory preference among breads with and without milk proteins and gums. Addition of CA and WA improved the baking quality by reducing the deterioration of frozen dough and retarding the staling of bread.

  • This study aimed to investigate quality characteristics of white bread with Tenebrio molitor L. powder (TMP). Because of the proximate composition analysis of the white bread with TMP, the content of protein and crude fat increased slightly in proportion to brown dough, and ash was highest in white breads with 7% added TMP. The bread volume decreased as TMP content increased. The control bread lightness was highest at 78.3, and was negatively correlated with the TMP content. The degree of redness increased with the TMP concentration. The total free amino acid contents were in the following order: white bread with 7% TMP > white bread with 5% TMP > white bread with 3% TMP. With respect to the texture, white bread springiness and cohesiveness with TMP decreased by storage period. The chewiness and brittleness of white breads with TMP decreased significantly with higher concentrations. With extended storage, the bread with TMP added showed lower springiness and cohesiveness; while bread with a lower TMP percentage maintained better chewiness and brittleness. The sensory taste preference was highest for white bread with 3% TMP. Residual appetite scores showed a lower taste preference as TMP content increased and was lowest for white bread with 3% TMP.

  • Sodium restricted diets are known to lower blood pressure in salt sensitive, hypertensive patients. Thare is increasing evidence that potassium plays an important role as a protective factor in the regulation of blood pressure. The objective of the current study was to measure parameters of sodium, potassium, and chloride utilization as affected by feeding of substantial quantities of bread made from whole ground white torn meal, whole ground yellow corn meal, and whole ground wheat flour. The breads provided 40 percent of a caloric content of the constant, measured laboratory diet. The 28-day study was divided into an introductory period of 7-days and three experimental periods of 7-days each. Order of assignment to specific treatments for 12 healthy subjects were according to a complete randomized block design. Yellow corn bread diets resulted in the highest potassium retention (243 mg/day) and the lowest urinary sodium and potassium ratio (1.53 $\pm$ 0.26) numerically in comparison to the other test breads. The excretions of sodium and chloride were higher during controlled feeding periods than during the self-selected diet period(p < 0.05). This indicates a response to the higher intake of these electrolytes from the experimental diets than from self-selected diets. There was no significant difference in the effect of white corn bread, yellow corn bread, or whole wheat bread diet on electrolyte status in humans. However, the yellow corn bread diet resulted in a somewhat more favorable urina교 sodium to potassium ratio than that from white corn bread or whole wheat bread diet.

  • The physiological and sensory properties of breads made from waxy black rice flour (WBRF) and wheat flour were investigated. The waxy black rice bread was manufactured with 10, 20, 30, or 40% waxy black rice flour(w/w). The bread volume decreased from 2,096.7 mL to 1,703.4 mL as the WBRF content increased from 0% to 40%. The lightness(L-values) decreased with increasing WBRF concentrations, and the redness value(a-values) increased. The yellowness(b-values) slightly decreased with increasing WBRF content. The textural characteristics of the bread c겨mb were influenced by additions of WBRF. The breads containing WBRF had decreases in hardness for the 10% and 20% WBRF groups, whereas increases in hardness were shown with the 40% addition of WBRF. The springiness decreased with increasing WBRF content. The gumminess and chewiness of the waxy black rice bread decreased at the 10% and 20% additions. In the sensory evaluation, sensory scores decreased with increasing WBRF content for the appearance, external color, crumb color and grain of the waxy black rice bread. Overall acceptability for the 10% and 20% WBRF additions did not differ significantly from the score of the control group.

  • Yacon (Smallanthussonchifolius) is a root crop that contains high amounts of fructo-oligosaccharides (FOS). FOS has a sweet taste, is low in calories, and is known to promote intestinal tract health. In this study, various yacon concentrates were substituted for sugar in white pan bread to obtain healthy benefits from the use of FOS. The quality characteristic changes during storage of the white pan breadswith 0, 25, 50, 75 and 100% of added yacon concentrates instead of sugar were investigated. During storage, the water contents and water activities of the breads made with high amounts of yacon concentrates changed less than in those made with only sugar. The hardness and chewiness of the breads made with high amounts of yacon concentrates had lower values than those made with only sugar. Thus, bread made with yacon concentrates might exhibit increased moisture retention and decreased aging velocity. The substitution of yacon concentrates for sugar in pan bread improved the bread quality.

  • The purpose of this study was to investigate the physicochemical and sensory properties of various breads prepared with purple-fleshed sweet potatoes and their powders. As the amount of purple-fleshed sweet potato and its powder increased, pH of the dough and bread, volume, dough yield, baking loss rate, and fermentation power of the dough decreased, whereas acidity of the bread increased. The lightness and yellowness of the breads decreased significantly, but redness increased with increasing content of purple-fleshed sweet potato and its powder. The textural properties, such as hardness, chewiness, springiness, and brittleness were significantly higher in groups with added purple-fleshed sweet potato and its powder compared to those in the control. The anthocyanin content and DPPH radical scavenging of dough and bread were higher in groups with purple-fleshed sweet potato and its powder than those in the control group. The groups with 5% and 10% purple-fleshed sweet potatoes and their powders had significantly higher scores for overall acceptability as compared to the control group.
