Studies to obtain a fundamental data to improve the quantity and quality of wheat protein and to select the excellent breeding materials suitable for various uses of it were performed on the focuses of protein content, amino acid composition, and its related quality. The range of seed protein content of crossing block consisted with 319 varieties or lines was from 9.9% to 17.6% with the average of 13.2%. The minimum protein content was showed by Wonkwang, and the maximum by Chungnamjaerae and Suwon 210. Among the Korean native varieties or breeding lines of crossing block, at least twelve lines or varieties were selected as the high-protein wheats. In the effects of environmental conditions, the variations of protein content by cultivating locations and year were showed out to be up to 3.6%, and 3.3%, respectively. But the varietal characteristics of wheat protein were seemed to remain constantly. In the results of amino acid analysis, those related with bread quality, except proline were improved with the increase of seed protein. But the improvement of nutritional quality did not agree with the protein content increase of seed. The total content of amino acid essential to adults was very low with 266.6-273.3mg per one gram of protein compare to the 350mg (free from the amino acid of tryptophan) recommended by FAO/WHO. Especially the limiting amino acid such as methionine, lysine and threonine were critically deficient. The correlation between protein contents and sedimentation values was obtained r=0.656$\^$**/ of average notwithstanding widly different environmental conditions, and in some condition the value was obained about to r=0.956$\^$**/.

This study was conducted to evaluate characteristic of breadmaking for white bread with fermented rice bran (FRB) (5 to 20%). In proximate composition analysis of FRB which was contained 38.72% moisture, 11.06% crude protein, 17.38% crude fat, 12.74% crude fiber and 11.85% ash. The degree of dough fermentation and dough pH tended to decrease depending on the degree of FRB powder, but there were no significant differences between control group and 5% FRB adding group. In bread weight and volume analysis, bread weight was decreased but bread volume was increased with FRB powder adding degrees. The color of crumb became darker according to the addition of FRB powder, but redness and yellowness were increased. The hardness, gumminess and brittleness of white bread showed a tendency to increase while cohesiveness and springness was decreased. In sensory analysis, FRB group showed generally low scores in color, flavor, texture, taste, overall acceptability except for 5% FRB adding group which showed similar results with control group. Taken together, FRB could be used as a nutrition improvement for breadmaking and a suitable FRB adding volume for breadmaking is 5%.

1. It is necessary for all cooks to understand the eggs for making the bakery. It will lead for them to make a difficient and reasonable job. 2. To understand the viscosity, Cooks have the view of the difference between the old eggs and the fresh eggs. 3. The cooks have the ability to apply the baking temperature by the exact understanding of the solidification. 4. The cooks have the basic knowledge to create the whipping items. 5. The cooks have the ability to develop the emulsion items by the exact understanding of the emulsification. 6. The cooks have the creativity to put in practice the bakery by reviewing the representative egg item.

사방을 둘러보면 커피 천지이다. 사무실이나 가정에서 쉽게 믹스커피를 타 마실 수 있고, 식당에 가면 커피 서비스는 기본이다. 맛좋은 원두커피를 마시고 싶으면 조금만 발품을 팔아 곳곳에 있는 원두커피 전문점을 이용할 수도 있으며, 편의점, 제과 제빵점 등에서도 커피를 파는 게 일상화되어 있다. 또 요즘은 건강에 좋은 웰빙 믹스커피나 손쉽게 마실 수 있는 캡슐커피도 나온다. 과거 자판기를 통해 한잔 마시면 족했을 커피가 이제 다양하기 그지없는 유통 수단을 통해 서비스 되고 있는 것. 가히 커피 천국이자, 커피 공화국이라 아니 할 수 없다. 아무리 불황여도 커피시장은 별다른 여파를 타지 않는다. 오히려 새로운 커피들과 유통수단이 속속 등장하며 시장 파이를 넓혀 가고 있다. 커피 시장의 급속한 트렌드 변화, 그리고 그 속에서 오히려 입지가 점점 약해지는 커피자판기 현실을 담아 봤다.

이제까지 숙주세포로 이용하기 위한 효모균주이 개발은 제빵효모인 Saccharomyces cerevisiae를 주대상으로 수행되어 왔다. 그러나 최근에는 Hansenula속, Pichia속, Kluyveromyces속, Schizosaccharomyces속, Schwanniomyces속 및 Yarrowia속 등 특이한 성질을 갖는 희귀효모 균주를 숙주세포로 한 새로운 유전자 발현시스템의 개발이 활발히 추진되고 있다. 본고에서는 S. cerevisiae를 위시하여 이들 희귀효모로부터 생산되고 있는 재조합 단백질의 연구현황과 문제점 및 재조합 단백질의 효율적인 생산을 위해 고려해야 할 요인들에 대해 고찰해 보기로 한다.

젤라틴은 척추동물을 비롯하여 무척추동물의 뼈 또는 껍질에 널리 분포하는 생체 단백질인 콜라겐의 유도 단백질로서 식품용은 물론 사진용, 캡슐제재 등의 약용 및 공업용으로 그 활용 범위가 매우 넓은 천연 단백질이다. 즉 젤라틴은 안전성이 극히 높은 식품소재로서 열가역적이면서 보수성, 콜로이드성 및 기포성 등과 같은 성질이 우수하기 때문에 젤리, 제과 및 제빵용, 유화제, 조미료, 육가공품의 품질 개량제, chewing gum의 base, 청주나 과즙 쥬스의 청징제 및 피복용 등 그 용도가 광범위하다. (중략)

젤라틴은 일반적으로 콜라겐의 가수 분해로 생성되어지는 단백질로서 대부분 동물의 결합 조직이나 피부, 배에 존재한다. 젤라틴은 젤리, 제빵 및 제과, 유화제 및 chewing gum base 등과 같은 식품용은 물론이고, 의약용, 사진용, 미생물 배양용 등으로도 사용되어 지고 있다. 젤라틴은 대부분 돼지나 소와 같은 육상 동물에서 얻어지고 있으나 최근 들어 광우병과 구제역과 같은 안전상의 문제가 대두되는 시점에서 그들의 대체 원료가 필요로 하게 되었고 이들을 대신하기 위해 어류에서 추출한 젤라틴에 많은 관심을 보이고 있다.

Effects of azodicarbonamide (ADA) were investigated on the rheological properties of flour dough by measuring farinogram, amylogram and extensogram based on the amount of ADA added. Quality characteristics of the bread made with the ADA added dough were also evaluated by measuring dough volume, moisture content, pH, proofed time, baking loss and textural characteristics. The farinogram showed that water absorption, stability and elasticity of the dough with ADA were higher than those without ADA. However, its absorption time and weakness decreased compared to the dough without ADA. Through the amylogram, it was found that gelatinization temperature and maximum viscosity increased, but temperature of maximum viscosity reduced in the dough with ADA. The extensogram showed that the area and resistance of the dough increased slightly but extensibility decreased drastically after fermentation, resulting in the ratio of resistance and extensibility (R/E) of the dough with ADA was lower than those without ADA. The bread prepared with the dough containing ADA after freezing up to 12 weeks showed higher pH and specific loaf volume but lower moisture content, second proof time and resistance than those without ADA.
