This study was conducted to investigate the effect of homogenized kimchi product (HKP) on dough characteristics and quality of bread. Fermented homogenized Chinese cabbage kimchi product was added 0.10, 20 and 30% to wheat flour. The pH of dough decreased with an increase in the amounts of HKP, which showed at PH 4.9 for the dough added 30% HKP. Fermentation time of the dough was reduced as much as 9~23 minutes as compared with the control products. Loaf volume index of the bread prepared by adding 10 ~30% HKP increased also by 12.7 ~ 19.0%. Hardness, cohesiveness, springiness and gumminess of the bread added with 30% HKP were lower than those of the control. The gas forming cell of the bread added with 30% HKP were good and regular. Crust and internal color of the bread with more HKP had tendency to redness. Sensory quality of the kimchi-bread estimated by shape, flavor and overall quality was better than that of control product, especially the kimchi-bread qualify at addition of 30% HKP was best.

Sweet dough bread is made by using sponge & dough method with the sweet dough formula which consists of wheat gluten and baking powder. The effect of wheat gluten and baking powder to the bread has been studied after the dough frozen, stored, thawed, fermented. and baked. The bread quality has been evaluated by measuring the product volute and also by the sensory evaluation after baking. When 4% of wheat gluten and 4% of baking powder were added into the dough. the bread has a larger volume than that of 2% wheat gluten and 2% baking powder in volume. However. wheat gluten shows better result than baking powder in terms of volume. In sensory evaluation, the bread has higher score when 2% of wheat gluten and 2% of baking powder were added into the dough than that of 4% wheat gluten and 4% baking powder. Consequently, breads show better result when 2% wheat gluten and 2% baking powder were added into the dough than that of 4% wheat gluten and 4% baking powder.

Physicochemical properties of bread as influenced by the addition of sweet pumpkin powder (SPP) were investigated. Freeze-dried sweet pumpkin was ground, sieved through a laboratory sieve and a fraction with particles less than $250\;{\mu}m$ was used. Amount of SPP added to the bread was found to affect the bread quality significantly (p<0.05). Loaf volume and weight of the control were significantly higher than others (p<0.05) and decreased significantly (p<0.05) with the addition of SPP. In other words, the enrichment of product with SPP decreased bread volume and weight without significant changes in the moisture content. There were distinctive color changes with the addition of the powder: L- and a-values were reduced but b-value was significantly increased (p<0.05). The hardness, springiness, and gumminess of bread were found to increase with the addition of the powder. Consumer test indicated that bread contained with 3% SPP had the highest overall acceptability score while 1 or 5% addition produced an acceptable quality for the bread.

To enhance the nutritional quality of the Soboru bread, a dietary fibers extracted from Kombu was added into wheat flour in the amounts of 0, 1, 3, and 5% and the quality of the baked products was characterized. The inherent water holding capacity of the added dietary fibers raised weight of the bread while specific volume and density values were decreased at the same time. Increasing the amount of dietary fiber resulted in the decreased setback time of the raw materials in amylogram. The lower textural hardness of the dietary fiber-enriched bread after one-day storage at room temperature could be attributed to the retarded retrogradation of the starch. Darkened surface of the bread as indicated by the Hunter colorimetric values and the accompanied change in flavor did not significantly influence the sensory evaluation of the products. Judging from texture, taste and overall acceptability of the product, recommended substitution level for the dietary fiber in Soboru bread was 3% or less. Increased intake of the dietary fibers, accompained with more use of seaweed, was expected through the suggested functional bread.

Objective of this experiment was to evaluate the effect of partial substitution of barley grain with bread by-product (BB) on performance of Awassi ewes and their lambs. Forty Awassi ewes rearing single lambs were randomly allotted into four experimental diets containing various levels of BB. The experimental diets contained 0 (BB0), 10 (BB10), 15 (BB15), and 20% (BB20) of BB on dietary dry matter (DM). The study lasted for eight weeks, in which the first week was used as an adaptation period and seven weeks of data collection. Ewes and their lambs were penned individually where they were fed their lactating diets ad libitum. Ewes and lambs body weights were measured at the beginning and at the end of the experiment. However, milk production and composition were evaluated biweekly. Feeding BB had no effect (p>0.05) on dry matter (DM), organic matter (OM), and crude protein (CP) intakes. However, neutral detergent fiber (NDF) intake was the lowest (p<0.05) for the BB20 and BB15 diets followed to BB10 diet (i.e., 640, 677, 772 g/d, respectively) while the highest NDF intake was for the BB0 diet (i.e., 825 g/d). Similarly, NDF intake decreased linearly (p<0.001) as the BB content increased. Acid detergent fiber (ADF) intake was highest (p<0.05) for the BB0 and BB10 diets (425 and 416 g/d, respectively) followed by the BB15 and BB20 diets (359 and 342 g/d, respectively). Moreover, a linear (p<0.001), quadratic (p = 0.04), and cubic (p = 0.04) effects were observed in ADF intake among diets. Nutrient digestibility was similar among different diets. Bread by-product had no effect (p>0.05) on ewes body weight change and on lamb performance (i.e., weaning body weight and average daily gain). Similarly, no differences (p>0.05) were observed either in milk production or composition by the BB substitution. Inclusion of BB reduced feed cost by 9, 14, and 18% for the BB10, BB15, and BB20 diets, respectively. No differences were observed in milk efficiency (DM intake: milk production; p>0.05) among diets. However, cost of milk production ($US/kg milk) was the lowest (p<0.05) in the diet containing BB20. Results of the present study indicate that feeding bread by-product up to 20% of the diet DM had no effect on performance of Awassi ewes and their lambs and reduced feed cost.

As interest in health has recently increased, many researchers have investigated the utilization of functional foods by confectioneries and bakeries. However, research on loaf bread containing beets has not been conducted. To investigate the optimal ratio of beet in loaf bread containing beet powder, characteristics of loaf bread according to 2%(B2), 4%(B4), and 6%(B6) beet powder per wheat flour were examined. The experimental results were as follows. Fermentation rate was reduced as content of beet powder increased compared with the control, whereas pH levels of dough and loaf bread significantly increased as content of beet powder increased. As content of beet powder increased, volume of loaf bread decreased, whereas specific volume increased. There was no significant difference in volume of loaf bread between the samples. As far as color changes are concerned, as content of beet powder increased, L value decreased, whereas a and b values increased with significant differences between the samples. Characteristics were examined by sensory evaluation of loaf bread containing beet powder. Color of inner texture and peel color of loaf bread significantly increased as content of beet powder increased. Size of air pores was largest in B4, and there was no significant difference in the uniformity of loaf bread between the control and experiment groups. As content of beet powder increased, rigidity of bread was reduced. Control showed the highest elasticity, whereas moisture level was highest in B2 with no significant differences between the samples. The flavor of beet was stronger as content of beet powder increased. In the preference test, B4 showed the highest preference scores for texture, flavor, taste, and overall likeness but not appearance. The experimental results showed that B4 among all control and experimental groups had the most suitable baking characteristics and an optimum content of beet powder. Therefore, B4 can be considered as the most appropriate for making loaf bread containing 4% beet powder in terms of physical and sensory characteristics. This is a new product that satisfies overall sensory preferences and has improved functionality.
