  • For a period of 5 days, the quality of breads with Paecilomyces japonica powder were investigated using chemical, sensory, and mechanical evaluations at $25^{\circ}C$. The result of analysis of chemical properties revealed that the pH value of dough was increased as the amount of Paecilomyces japonica powder increased, but volume of dough and baking loss rate were decreased. Breads with 1% and 2% Paecilomyces japonica powder showed a good overall preference in sensory evaluation. As storing time passed. moisture content, lightness, and redness were decreased in all breads, but yellowness increased. Hardness and gumminess of texture analysis were increased as storing time passed, but springiness decreased. Springiness of the mechanical properties was negatively correlated with pH value of dough and volume of bread, while was positively correlated with volume of dough and baking loss rate. In the analysis of correlation between sensory and mechanical properties showed that hardness of mechanical properties had negative correlation with softness, moistness, and springiness. Cohesiveness of mechanical properties had positive correlation with acceptability.

  • The studies were carried out to optimize a new starter for bread fermentation. Two strains of lactic acid bacteria and yeast were isolated from Kimchi. These strains showed good condition for quality bread fermented. The strains identified as Leuconostoc mesenteroides, Lactobacillus brevis, Saccharomyces fermentati and Saccharomyces cerevisiae. The mixed culture of four strains was due to the synergistic effect by interaction of these strains.

  • This study was performed to find out the usefulness of chestnut powder recovered from the inner layer, which used to be discarded. After the Physicochemical properties of the chestnut powder were examined, breads were prepared with 10-50% of chestnut Powder and the sensory quality was compared by QDA. Bread could be made even using up to 50% of chestnut powder, and in 20-30% of chestnut powder, the sensory quality was acceptable enough compared with wheat bread. Even though the low purity of the chestnut powder affected the flavor and color, the breads contained it were generally acceptable. Therefore, the chestnut powder recovered from the inner layer can be used as the effective food resource as itself, and with the higher purification to remove inner layer, it can be applied to more diverse food.

  • This study was conducted to test the white bread dough with substitution of 1, 2, 3, 4 and $5\%$ kimchi powder on farinograph, extensograph, amylograph, and pH to find the dough development time, stability, extensibility, resistance to extension, temperature at gelatinization, and temperature at maximum viscosity. Dough with kimchi powder showed less moisture absorption than control. Upon increasing amount of kimchi powder, pH was decreased and dough development time was increased Extensibility of dough showed negative correlation with amount of kimchi powder added Gelatinization temperature increased but maximum viscosity temperature decreased as the amount of kimchi powder increased Overall, the samples with substitution of kimchi powder showed better extensibility than the control sample at the first fermentation.

  • The purpose of this study was to examine the perceptions of herbs as a bread additive among 880 university students(436 male and 444 female). A sensory evaluation was also undertaken to investigate the taste and qualitative aspects of breads with various herb additives such as rosemary and mint. First, rosemary was the most popular(40.9%), followed by mint(28.5%) and lavender(10.9%). Second, sensory evaluation gave a positive response rate of 85.8% for the breads and cookies with added herbs. Third, in terms of using herbs for breads and cookies, respondents favored mint as the favorite with 58.1%, followed by rosemary with 57.9%. Fourth, in terms of sensory test, the highest preference was scored by the bread with 2% mint and 2% rosemary, and this ingrediebt mixture was confirmed as the best to make herb added breads.

  • 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.

  • 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.

  • 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.

  • The purpose of this study is to explore the daily meal pattern in Seoul families. The informations of this study were obtained from 443 housewives in Seoul during August 20 to September 20, 1994, by using questionnaires. The X2 test was applied to see the individual data. The following observations were made in this study. 57% of Seoul families had rice with side dish set three times a day, the first choice for rice substitute was bread In breakfast and noodle in lunch, 98% of the subjects had rice in dinner The change of tile meal pattern from boiled rice to bread and noodle was the result of social changes such as urbanization, heightening up of education level of woman and the resulting increase of woman employment. They were consumed 2~5 varieties of side dishes. The favorite were Kimchi and Cigag' and Guk. The major meal pattern In Seoul Is still the traditional one composed of boiled rice and side dishes.

  • This study was conducted to determine feasibility of utilization of Angelica acutiloba. Especially, the quality characteristics of bread prepared with the addition of Angelica acutiloba powder were investigated. Sensory evaluation and spoilage test were conducted for preparation of functional breads which added with ground plant matters (leaves and stems) from Angelica acutiloba. The result showed that the functional breads had high score of overall liking as well as low spoilage rate when added with 0.5 to 1.0% ground plant matters of Angelica acutiloba. Consumer acceptability evaluation showed a significant preference when added 0.5 to 1.0% ground leaves and stems of Angelica acutiloba into breads. Functional breads which added powder of Angelica acutiloba inhibited the growth of fungi. The more addition of Angelica acutiloba powder, the higher the degrees of this inhibited. These results suggested that the shelf-lives of the breads were extended by the addition of Angelica acutiloba powder. Further studies were required for improvement of functionality and diversity of bread products using medicinal plant materials as an additive.
