  • End-use properties of six Korean waxy wheat lines and their parental plants were evaluated in this study. Korean waxy wheat lines showed unsuitable characteristics for end products, such as sticky crumb of bread, sticky cooked wet and dry noodles and small cookie diameter. Korean waxy wheat lines produced lower loaf volume and less desirable crumb grain structure of bread, and lower chewiness of cooked wet and dry noodles than their parental plants even though Korean waxy wheats were much higher in protein content and SDS-sedimentation volume than their parental plants. We observed adverse effects of high flour protein content in Korean waxy wheat lines, such as smaller cookie diameter and harder snapping force than those produced from their parental plants.

  • Breadmaking is a complex system in which many variables govern the production of acceptable bread. Lipids, a minor component of wheat flour, function importantly in bread-making. Shortening, or fat, is one of the essential ingredients in commercial baking. Beneficial shortening effect depends on type and quantity of lipids present in wheat flour and also on wheat flour quality. Surfactants have been used in baking industry during last decade because certrain surfactants can replace shortening and/or natural flour lipids. A proper combination of lipidshortening-surfactant is more useful in the production of specialty breads such as whole wheat breads, high protein breads, high fiber breads or even non-wheat composite breads rather than in the production of regular white breads. This presentation is a review of recent studies on the contribution of flour lipids, shortening, and surfactants, alone or in combination in the production of breads; illustrations are mainly from data obtained in the author's laboratory.

  • Yellow rust (stripe rust), caused by Puccinia striiformis f. sp. tritici, is one of the most destructive foliar diseases of wheat in Egypt and worldwide. In order to identify wheat genotypes resistant to yellow rust and develop molecular markers associated with the resistance, fifty F8 recombinant inbred lines (RILs) derived from a cross between resistant and susceptible bread wheat landraces were obtained. Artificial infection of Puccinia striiformis was performed under greenhouse conditions during two growing seasons and relative resistance index (RRI) was calculated. Two Egyptian bread wheat cultivars i.e. Giza-168 (resistant) and Sakha-69 (susceptible) were also evaluated. RRI values of two-year trial showed that 10 RILs responded with RRI value >6 <9 with an average of 7.29, which exceeded the Egyptian bread wheat cultivar Giza-168 (5.58). Thirty three RILs were included among the acceptable range having RRI value >2 <6. However, only 7 RILs showed RRI value <2. Five RILs expressed hypersensitive type of resistance (R) against the pathogen and showed the lowest Average Coefficient of Infection (ACI). Bulked segregant analysis (BSA) with eight simple sequence repeat (SSR), eight sequence-related amplified polymorphism (SRAP) and sixteen random amplified polymorphic DNA (RAPD) markers revealed that three SSR, three SRAP and six RAPD markers were found to be associated with the resistance to yellow rust. However, further molecular analyses would be performed to confirm markers associated with the resistance and suitable for marker-assisted selection. Resistant RILs identified in the study could be efficiently used to improve the resistance to yellow rust in wheat.

  • Baking properties of Korean domestic wheat flour supplemented with pine pollen powder were investigated. Farinographic characteristics showed that the addition of pine pollen increased water absorption without any changes in dough development time and stability of dough in comparison with control. A higher gelatinization temperature and a lower maximum viscosity of dough on amylogram were observed with pine pollen powder addition. The addition of pine pollen powder showed decrease in redness and increases in lightness and yellowness of bread crumb. A significant increase in bread volume was observed as the pine pollen powder added more. Springiness. cohesiveness and resilience of bread were increased by pine pollen powder. Sensory evaluation of bread showed that the addition of pine pollen powder, especially at the level of 1%, enhanced color, mouth feeling, bleak and appearance without significant reduction of overall acceptability.

  • The purpose of this study was to survey the current status of bread menus at school, business and industry (B & I), and military foodservice operations and to analyze dietitians' perceptions of applying rice bread in foodservice menus. A questionnaire, which was developed by content analysis, situation analysis, and in-depth interview, was distributed to 183 schools, 31 B & I operations, and 26 air force dietitians. In the school and B & I foodservices, wheat bread was used much more than rice bread and serving frequencies of morning rolls and sliced bread were higher. The military foodservices, however, served much more rice bread as burger buns than the other groups. For the school and B&I operations, consumer preference for wheat bread was perceived as high. In contrast, soldiers preferred rice bread to wheat bread in the military foodservices. The recognized advantages of using rice bread were different among the three groups. The military dietitians perceived the main advantage of using rice bread as an increase of rice consumption, while the school and B & I dietitians viewed it as promoting a healthy image. In all groups, the primary difficulties for using rice bread were the higher cost of rice bread as compared to wheat bread and a lack of facilities (e.g. oven). The military dietitians had the highest levels of positive and active interest as well as intention and opinions toward using rice bread. On the other hand, the school and B & I dietitians had very positive perceptions of rice bread but did not actually apply it in their foodservice menus. Overall, the results of this study suggest that the development of diverse menus using rice bread along with government support of its use, including facilities with ovens as well as rice bread subsidies, should be carried out for on-going expansion of the rice bread supply.

  • The baking property, chemical composition, instrumental characteristics and sensory quality of yeast breads containing various mixing percentage of Job's-tears flour with wheat flour were studied. The loaf volume and baking quality of the yeast bread made from mixing of 30% Job's-tears flour were similar to those of wheat flour bread. The contents of crude protein, crude fat, and crude ash in Job's-tears flour breads were much higher than those of wheat flour brad. Instrumental rheological characteristics of the yeast breads were measured with a Texture Analyzer. As the addition level of Job's-tears flours increased, hardness of the yeast breads increased but fracturability, adhesiveness, springness, cohesiveness, gumminess, chewiness and resilience decreased. The results of sensory evaluation revealed that Job's-tears flour was added to wheat flour at a replacement level of 10% without a large adverse effect on flavor, taste, mouthfeel and aftertaste.
