  • Bread baking parameters and relationships between bread baking properties and flour characteristics were evaluated for two years, 1997 and 1998, and at two locations, Suwon and Deokso, with Korean winter wheat cultivars and lines. Among the bread baking parameters, lightness of crumb grain showed differences between years. No significant differences were found in dough mixing time, bread loaf volume, crumb grain score or firmness. Keumkangmil, Suwon 278 and Tapdongmil showed higher bread loaf volume, good structure of crumb grain and softer crumb firmness. However, compared to commercial flours for baking, cultivar means averaged over years and locations of nineteen Korean winter wheats showed poor bread baking quality because of low protein content and unsuitable protein quality. Protein content and flour swelling volume showed better relationships with the bread baking parameters than other flour characteristics. Friabilin-absence lines showed softer crumb firmness than those of friabilin-presence lines.

  • 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.

  • The purpose of this study was to examine the quality characteristics of white pan bread according to the different types of water (tap water (still water), purified water, still water, light water, classical water, and bold water). Pan breads were statistically analyzed using texture profile analysis, fermentation, texture, suitability, image analysis, color, moisture content, and statistical analysis. This result will contribute to the commercialization of pan bread using various kinds of water. Ultimately, we analyzed the quality characteristics of various kinds of water, depending on the carbonic acid content on the dough and the pan bread, and to derive the optimum kinds and ratios of the water to be applied to the pan bread. As a result of the study, the best findings were obtained with water containing carbonic acid content more than the classical water according to overall characteristics, durability (Width of Tail and Integral), foot efficiency, softness, volume and preference check. Therefore, when white pan bread is produced by using water containing a carbonic acid content (5~7.5 mg/L) or more of the classical water, it affects the quality characteristics and a good obtains positive response to from consumers. In this study, the quality characteristics of pan bread based different kinds of water which were not available in the past, and the quality characteristics of pan bread, which can be used as the basic data for future research, were well analyzed.

  • The quality characteristics of bread prepared with the addition of dried persimmon peel powder(PPP) were investigated. Visco-elastic characteristics of dough and texture of bread added PPP was examined by rapid visco-analyzer and texture analyzer. The maximum viscosity of the dough with PPP was lower than that of control at 90$\^{C}$. Final viscosity after cooling to 50$\^{C}$, viscosity of control increased to 134 B.U., but that of the dough with PPP showed 13∼37 B.U. As more PPP was added, gluten formation and mixing time dough were longer. Adhesiveness, springness, cohesiveness and chewiness gradually increased as PPP content increased, while the hardness decreased. Lightness value decreased but redness and yellowness values increased with the addition of PPP, especially, the bread made by 15% PPP treatment showed dark brown color. In sensory evaluation of bread, score of color decreased significantly as more PPP was added but overall acceptability was not significant different(p<0.05) between control and 5% PPP treatment. It is considered that the addition of 5% was appropriate for bread making with PPP.
