  • This study investigated both the chemical and antioxidative characteristics of wheat flour added with 10, 20 and 30% immature chalssalbori flour; further, the quality characteristics of bread dough during yeast fermentation were assessed. As the addition rate of chalssalbori flour into wheat flour increased, the DPPH radical scavenging capacity, water absorption index, water solubility index and viscosity were all increased. Moreover, the bread dough with an increased addition rate of chalssalbori flour demonstrated an increased pH, reduced fermentative expansion power and a darker yellowish color. The bread dough added with chalssalbori flour after mixing showed higher hardness, gumminess and adhesiveness, but lower cohesiveness and springiness compared to the control; however, these texture characteristics were changed during fermentation. In the present study, the mixed flour with 10% immature chalssalbori flour conveyed similar pasting characteristics to those of wheat flour; moreover, its bread dough showed higher springiness and fermentative expansion power. Furthermore, a delay effect of starch retrogradation can be expected compared to the control.

  • Breads were prepared from wheat flour supplemented with oyster mushroom (Pleurotus ostreatus) powder, and effects of the supplementation of oyster mushroom powder on dough rheology and bread quality were examined. The initial pasting temperature in viscoamylograph increased, but peak and final viscosities decreased with the increased amount of oyster mushroom powder. The gradual increase of water absorption, dough development time and mixing tolerance index, and decrease of dough stability with the increased amount of oyster mushroom powder were obtained by farinographs. The supplementation of oyster mushroom powder had an effect on the bread making, resulting in an increase of loaf weight and a decrease of loaf volume. The rough and coarse crumb texture with dark color was observed with the increased amount of oyster mushroom powder. The firmness of bread crumb containing oyster mushroom powder was increased during storage periods. Sensory evaluation revealed that the addition of $1\%$ oyster mushroom powder could be supplemented to make an acceptable quality of bread.

  • 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.

  • To establish the optimum formular for processing bread with steam-dried Hizikia fusiformis flour(SHF), it was incorporated into wheat flour by the ratio of 0, 1, 3, 5 and 7% based on a flour weight. Evaluation was performed on the rheological and sensory profile of bread, such as specific loaf volume, water holding capacity(WHC) and height, appearance and Hunter's color value, mechanical texture properties, and sensory value. Increase in the addition of SHF led to the tendency that the expansive force of dough fermentation reduced, and an increase in the textural properties of bread. And cohesiveness, gumminess, and chewiness indicated the tendency of a little reduction as influenced by adding more dried Hizikia fusiformis powder. As for sensory properties and flavor components of the white bread, in case of color and flavor, more than 3% of increase in the addition of the dried Hizikia fusiformis powder led to a drop in preference, and more addition led to a fall in taste and softness. Overall, it was found that adding less than 3% of dried Hizikia fusiformis powder is proper for dough in breadmaking.

  • The aim of this study was to investigate the effects of mulberry extracts on the physical characteristics of dough and the quality characteristics of oddi bread. The peak time of all experimental doughs except ME 25 (25% mulberry extracts) was suitable for breadmaking. The fermentation rate was decreased in accordance with the addition of mulberry extracts and the pH of the dough was decreased from 5.96 to 5.29. L values of oddi bread decreased with increasing mulberry extracts whereas, a and b values increased. The sensory evaluation indicated that crumb and crust color of the control bread was the brightest among the experiments. Flavor and taste was high as the addition of mulberry extracts. The overall acceptance was preferred at ME 25. Since the outcome of the mixograph at ME 25 tended to be low in bread-making, the utility of mulberry extracts at 20% (flour basis) was appropriate.

  • This study investigated the feasibility of the bread making process with the mixture of the functional rice flour. The bread was manufactured with 20, 30 or 40% functional rice flour with increasing and wheat flour. Gelatinization characteristics of the rice starch was examined by differential scanning calorimetry(DSC). Coated with soluble dietary fiber rice showed the highest gelatinization enthalphy among functional rices and other functional rices were similar to normal rice. in the viscosity point of view. generally the viscosity related to the addition ratio. The most viscose case was 30% Sangwhang rice but in fermented with monascus ruber rice case, viscosity was low even with 40% case because of the transformation of the starch granules. In sensory evaluation, the highest sensory scores for the uniformity of pore size and flavor were obtained when sangwhang rice flour content was 20%. The textual study was mainly focused on the hardness, cohesiveness, adhesiveness, springiness, chewiness. Textural characteristics of functional rice bread crumb bakedwith 20% coated with soluble dietary fiber rice, 20% sangwhang was low in hardness, chewiness and gumminess. Therefore, Sangwhang rice flour 20%, Monascous ruber 20% and Coated soluble dietary fiber rice 20% were considered to be the most suitable addition ratio for the rice breads.

  • The objective of this study was to investigate quality characteristics of sourdough bread with fermented Zante currants juice. The sweetness of fermented Zante currants starter increased while its pH value decreased as time passed. The pH values were negatively correlated to the added amount of starter with the lowest pH being recorded at 70% addition. Similarly, bread's moisture was inversely correlated to the added amount of starter with the highest moisture content being recorded at 10% addition. For bread's height, excluding the control, 70% addition turned out to be the highest, and the height decreased as the added amount increased. The oven-spring was similar between the control and 70% addition. For the volume, except the control, 70% addition turned out to be the largest. The larger the specific volume was, the higher the volume of bread got. The brightness, redness, and yellowness were decreased as the added amount was increased. For the texture, the control had the highest elasticity and cohesiveness, and they increased as the added amount of starter increased. The hardness had a negative correlation with the added amount, and 70% addition yielded the same result as the control. The adhesiveness appeared only in 10% addition.

  • This research is about the quality characteristics of white bread mixed with varying ratios of Seomcho powder, such as 1%, 3%, 5%, and 7% (Spinacia oleracea L.). The pH level of dough decreased as more Seomcho powder (Spinacia oleracea L.) was added, and 7% addition recorded the lowest pH. The fermentation power of dough expansion decreased as the additional ratio increased in both the first and second proofing, and it was negatively correlated to the fermentation time factor. The moisture content of bread decreased as the addition ratio increased. The bread volume became smaller as the addition ratio increased, but it correlated negatively with its specific volume. The color of the crumb, the lightness and redness decreased in comparison to the control, but the yellowness increased. The total amino acid contents increased as the addition ratio increased, and glutamic acid was positively correlated to the additional ratio. The total free amino acids increased as the additional ratio increased, but cysteine levels were high at 5% and 7% additional ratio. The textural characteristics of the bread, springiness and cohesiveness were lower than the control, but gumminess, brittleness, and hardness were higher than the control. The adhesiveness was realized at 7% additional ratio.

  • The present study examined optimal level of mulberry leave powder, and the method of bread-making were proposed to utilize mulbery leave powder by investigating rhelogical properties of dough and sensory evaluation of bread. The difference of amino acids compositions in flour brew were also investigated by fermentation of S. cerevisiae or bifidobacteria. As the % of mulberry leave powder increases absorption rate of dough was steadily increased, but stability and R!E ratio if dough were dramatically decreased more than 1% leave respectively. R!E ratio value, which indicates gas retnetion property of dough, was not obtained at the level 5%. Gelatinization temperature and maximum viscosity temperature showed a tentency of decrease, resulting in easier cooking of dough. The delay of temperature cauesd by addition of mulberry leave powder was overcome by two step bread making, that is, modified straight dough method adding flour brew fermented 16hrs by bifidobacteria. The firmness of bread was progressively dreased as the amount of mulbery leave powder increased. The addition of 2% level of mulberry powder to bread showed no significant difference comparing with control in sensery evaluation. Amino acids compositions of Flour brew fermented by bifidobacteria was superior th that by S. cerevisae nutritionally.onally.
