  • The purpose of this study was to determine the optimal mixing ratio of Allium hookeri powder and butter in the preparation of bread. The experiment was designed according to the central composite design for estimating the response surface, which demonstrated 10 experimental points, including 2 replicates for Allium hookeri powder and butter. Further, the mechanical and sensory properties of test materials were measured. A canonical form and perturbation plot conveyed the influence of each ingredient on the final product mixture. Overall, the measurement results of the mechanical properties showed a significant increase or decrease in dough pH, sweetness, volume, weight, height, specific volume, a & b-value of crumb and, springiness (p<0.05). Moreover, the sensory measurements demonstrated a significant improvement in color, appearance, texture, moistness and, overall quality. As a result, the optimum formulation from the numerical and graphical methods was calculated as 22.65 g of Allium hookeri powder and 47.77 g butter. After optimization, DPPH free radical scavenging activity, total phenolic content, and total plate counts over 10 days were evaluated. In sum, the results revealed the antioxidant and antibiotic actions of bread with Allium hookeri powder.

  • The purpose of this study was to develop functional bread added with dried mulberry pomace. The effect of dried mulberry pomace (0, 1, 3 or 5%) on the quality characteristics of breads was evaluated. The weight, volume and height were higher in bread added with dried mulberry pomace, compared with control bread. As the concentration of the dried mulberry pomace increased, decreased in pH and increased in acidity. The sugar concentration($^{\circ}Brix$) and reducing sugar(%) increased with the amount of dried mulberry pomace. The hunter color system L(lightness) and b(yellowness) value of the crumb of breads with increasing dried mulberry pomace were decreased, but the a(redness) value was increased. Contents of total phenol increased with addition amount of dried mulberry pomace. The antioxidant activities such as DPPH and hydroxy radical scavanging activity of the dried mulberry pomace increased with increase of dried mulberry pomace amount. The sensory results showed that scores of over-all preference of the breads added with dried mulberry pomace were higher than that of control.

  • Pyrenophoratritici-repentis is the causal agent of tan spot. According to their ability to produce necrosis and/or chlorosis on a set of four differential bread wheats, the isolates of this fungus are currently grouped into eight races. When durum wheat genotypes were added to the differential set, a new virulence type was identified in Algeria. The isolates showing this virulence pattern are unable to attack bread wheat while they cause necrosis in durum genotypes. In this work, characterization of those isolates was based on pathological and molecular aspects. This included inoculation of bread and durum wheat, and virulence gene analysis using PCR and sequencing. The results showed that all isolates caused a resistance on all bread wheats of the differential set, while they produced necrosis in durum. ToxA and ToxB genes were amplified in all isolates, whereas toxb was absent. Sequence analysis for both genes showed no differences with those found in the two functional genes. The presence of two genes, ToxA and ToxB, despite the absence of symptoms usually caused by their products, suggests the existence of a new homologous for these two genes yet unknown. The presence of ToxA in the isolate unable to produce necrosis in Glenlea is reported for the first time.

  • This study analyzed the general components of rice bread with 75% rice content such as water, crude ash, crude protein, crude fat and carbohydrate, and its nutrients such as vitamin C, vitamin A, vitamin E content, minerals, amino acids, and fatty acids. The contents of crude protein were high and those of crude fat were low with the contents of crude ash, crude protein, and crude fat being 1.61, 18.50, 0.04 g/100 g respectively. Vitamin A was not detected and the contents of vitamin C and vitamin E were 3.85 and 3.04 mg/100 g, respectively. The calcium, potassium, magnesium, iron and sodium contents were 222.0, 117.90, 24.12, 2.30, 555.90 mg/100 g respectively. Rice bread contains 9 essential amino acids such as valine, leucine, isoleucine, methionine, threonine, lysine, phenylalanine, histidine, and arginine. The analysis of rice bread fatty acid showed 58.04 mg/100 g of saturated fatty acid, 26.31mg/100 g of monounsaturated fatty acid and 15.64 mg/100 g of polyunsaturated fatty acid. The total essential fatty acid content was 15.49 mg/100 g. With the rising interest in processed rice products, well-being, and diet, it is necessary to develop processed rice foods that are nutritional and low in calories using rice powder that is nutritionally better than flour.

  • There are no reliable data about the effect on the baking industry in Korea yet. The damage caused by the product's aging is so much in the confectionary and baking industries. Therefore, the aging of bread is an economical problem which determines its commercial lifespan. In order to solve out this aging problem, this article dealt with the factors which give rise to the effect of starch on the aging and its inhibitory methods. 1. Control of the moisture content : Because the aging of starch occurs at 30~60% of moisture most frequently, controlling the moisture content above or below the above percentage can help restrain the aging to a certain degree. 2. Addition of sugars : The sugars become hydrated through hydrogenation with the moisture in the food. Thus, the sugars suppress the phenomenon of crumbling inside the food acting as a kind of dehydrator. 3. Use of an emulsifying agent : The emulsifying agent increases the stability of starch colloid liquid and suppresses the precipitation of starch molecules and the formation of crystallized range to prevent aging. 4. Method by freezing : The aging of starch does hardly occur reaching -2$0^{\circ}C$~-3$0^{\circ}C$ below zero. 5. Maintenance of warm condition : The freshness of bread is maintained at the 80% of humidity at 5$0^{\circ}C$.

  • The overall effects of three different beers on white bread were examined in terms of mixograph, pH, fermentation rate, TPA, crumbScan, colorimeter, sensory evaluation, and the hardness of bread through different storage times (0, 1, 2, 3 days), and texture as measured by texture analyzer. According to mixograph, the control (CON), black beer stout (BOB) and Asahi beer (AOB) but not max beer (MOB) were found to be proper between 3 and 5 minutes of peak time. All samples for peak value were at the level of over 60%. AOB showed the highest specific volume, and was the lowest in hardness (i.e. highest in softness) by TPA and storage days. In sensory evaluation, the difference test showed that AOB had the best volume, springiness, moistness, and softness. Moreover, in an overall preference test AOB scored the highest points in texture, flavor, taste, and overall acceptance.
