In contemporary society, consumers increasingly demand foods that provide health benefits and satisfy taste. As a result, the importance of functional foods has risen, particularly in the development of functional bread using various ingredients. This study examines the impact of different functional ingredients on bread quality, including plant-based components like vegetables, fruits, and grains, as well as animal-derived materials, medicinal herbs, and other additives. The study evaluates changes in the physical, chemical, and sensory properties of bread dough. Plant-based ingredients improved the color, flavor, and texture of the bread, enhancing its overall sensory quality. They also increased water absorption in the dough, improving its appearance and texture. Animal-derived ingredients, especially from insects, enhanced the physical properties and nutritional value of the dough. Medicinal herbs significantly boosted the bread's nutritional value and health benefits through antioxidant and anti-inflammatory properties. The findings show that functional additives play a crucial role in improving bread quality, providing valuable data for the development of functional foods that meet modern consumer demands for health benefits and good taste.

The aim of this study was to determine the quality characteristics of bread with 2%, 4%, 6%, and 8% cuttlefish ink added. The pH of the dough decreased as the addition percentage increased, and the addition of 8% was the lowest. The pH of the bread and the fermentation expansion power of the dough decreased as the addition percentage increased. Moisture and ash content were positively correlated with the addition percentage, and the crude protein and crude ash content were negatively correlated. As the addition percentage increased, the color of the bread became darker, and the bread volume decreased. The inside and outside color of the bread also decreased as the addition percentage increased. The volume and specific volume of bread decreased as the addition percentage increased. The amino acid analysis indicated glutamic acid was the largest, free amino acid analysis pointed out aspartic acid the highest. The springiness, cohesiveness, gumminess, brittleness, and hardness of the bread were positively correlated with the addition percentage. Overall, it seems possible to develop bakery items using cuttlefish ink as a functional ingredient.

With the advancement and diversification of the bread industry, eco-friendly products with less sugar and salt, and containing functional ingredients are being developed. To develop healthy bread, Korean pine leaf powder was added in different proportions (0%, 1%, 3%, 5%, and 7%), and the quality characteristics of the bread, namely height, moisture, color value, texture, antioxidant property, and sensory characteristics were evaluated. As the amount of leaf powder was increased in the bread, L-value in the range of 53.45~85.05 (p<0.001) and adhesiveness in the range of 0.13~0.32 mJ (p<0.001) decreased significantly, whereas b-value in the range of 16.75~30.74 (p<0.001), total polyphenol content in the range of 466.83~669.13 ug/mL, ABTS- in the range of 0.46~43.23%, DPPH-radical in the range of 1.39~45.76%, scavenging capacities (p<0.001), color in the range of 3.27~5.40 (p=0.017) and texture in the range of 4.33~4.80 (p=0.006) preferences increased significantly. This study could increase the utilization of Korean pine leaf and the production of healthy food with antioxidant properties.

Tempeh is a traditional Indonesian food that is fermented soybeans with Rhizopus spp. and contains high-quality protein. In this study, tempeh and yeast were set as independent variables following the central composite design to optimize the nutritional quality and sensory characteristics of high-protein loaf bread added with tempeh. The optimal mixing ratio was calculated through the response surface methodology. The optimal mixing ratio of tempehadded loaf bread was 11.27 g of tempeh and 5.46 g of yeast. A comparative analysis of the quality characteristics between the tempeh-added loaf bread and the control group produced by the optimal recipe showed that tempehadded loaf bread contained higher protein content, lower carbohydrates and fats, and lower calories. Among amino acids, essential amino acids such as aspartic acid, threonine, glycine, alanine, lysine, and histidine were significantly higher in tempeh-added loaf bread. Among fatty acids, butyric acid, capric acid, myristic acid, palmitic acid, palmitoleic acid, and heptadecanoic acid were significantly higher in tempeh-added loaf bread, while lauric acid, linoleic acid, and linolenic acid were significantly lower. This study confirmed the suitability of tempeh as an ingredient for protein-enhanced loaf bread and the potential possibility of it being utilized in bakeries.

The purpose of this study was to investigate the quality characteristics of bread made with 1%, 3%, 5%, and 7% of Bigeumdo Seomcho powder (Spinacia oleracea L.). The pH of dough and bread decreased as the amount of addition increased; 7% indicated the lowest. The moisture level correlated negatively with the powder addition, but the difference was not statistically meaningful (p<0.05). As the amount of addition was increased, the intensity of color increased but the volume decreased. The brightness and redness of the bread decreased as the amount of addition increased. The volume, specific volume, and baking loss rate correlated negatively with the powder addition. Regarding springiness, cohesiveness, and gumminess, the experiment group was higher than the control group and they lowered as the addition amount increased. The brittleness showed positive correlation with the addition amount. Out of the amino acids of bread, glutamic acid showed the highest value as the amount of addition was increased. Overall, it is possible to produce bakery bread using functional ingredients.

Attempts to increase the usability of lilies led us to prepare pulverized lily bulbs, which we then added to bread flour to bake white pan bread. The properties of the frozen dough and the quality characteristics of the bread were analyzed. Our experiments showed that the addition of lily powder decreases the viscoelasticity and stability of frozen dough. The absorption rate of the frozen dough was 63.1±0.2% for the control sample, and 66.1±0.1% and 70.9±0.2% for the normally pulverized samples containing 3% and 5% of lily powder, respectively, whereas the absorption rate of the finely pulverized samples tended to increase slightly. The gelatinization results of the frozen dough decreased with the addition of lily powder in terms of the final viscosity, break down, and setback values. Compared to the control sample, the specific volume of the bread products that underwent normal pulverization (5% additive) increased slightly and decreased for the lily bulbs that were finely pulverized (3% additive). The addition of lily powder did not significantly affect the water activity during the storage period of up to 5 days. The hardness of white pan bread increased from 1,948±114.3 to 2,518±154.7 g/㎠ on the first day of storage to 2,571±160.9 to 3,265±147.4 g/㎠ on the 5th day of storage. The hardness was the highest for the 5% sample that underwent normal pulverization, and the samples differed significantly. The longer the storage period, the lower the springness value of the white pan bread became, and this result was most notable for the finely pulverized powder sample. The springness of white pan bread decreased as the amount of lily powder additive and the storage period increased. The sensory test results were excellent in that the appearance, texture, flavor, taste, and overall preference for white pan bread to which 3% of normally crushed lily powder had been added had improved relative to the control sample.

This study was conducted to evaluate the characteristics of bread and the rheology of flour dough containing chlorella powder(0%, 0.5%, 1.0%, 1.5%, 2.0% and 2.5%). In the farinograph test, the addition of chlorella powder changed water absorption, development time and mixing tolerance index for making bread. As the amount of chlorella powder increased, the water absorption increased, mixing tolerance index and the development time decreased. In the extensograph test, the degree of extension and resistance was decreased with increasing of chlorella powder content. In the amylograph test, the maximum viscosity was slightly decreased with increasing of chlorella powder contents. The colors of L value in bread crumb was significantly decreased as the chlorella powder addition. After fermentation treatment, The dough with 2.5% chlorella powder showed the lowest dough raising power compared to the other doughs. The addition of the chlorella powder had significant effect on bread texture. The bread consisting of 0.5% chlorella powder showed the highest volume of loaf and specific volume. Therefore, high quality of bread can be achieved by adding chlorella powder.

The purpose of this study was to evaluate the quality characteristics of white pan bread added with wheat sprout powder without treatment (WP) and wheat sprout powder with only enzyme treatment (WPE), only lactic acid bacteria treatment (WPL) and enzyme and lactic acid bacteria treatment (WPE&L). The three different powder concentration levels of 1%, 3%, and 5% were added to flour to produce the white pan bread. The bread volume and specific volume of the WPE&L group were the highest among all the addition groups. The bread weight, a-value, and b-value of the WP group was highest among all the addition groups, but the bread baking loss and the L-value of the WP group was the lowest among all the addition groups. The texture measurements indicated that the hardness, gumminess, and chewiness values of the bread were the highest in the WP group. The sensory evaluation test showed that bread in the WPE&L group with 3% wheat sprout powder was the best among all the samples studied. Based on our findings, we suggest that the enzyme and lactic acid bacteria pretreated wheat sprout powder is an effective ingredient for improving the overall quality of white pan bread.

The purpose of this study was to prepare bread added with sea buckthorn (Hippophae rhamnoides L.) berry powder (SBBP) (1, 3, and 5%) using a straight dough method. The quality and antioxidant characteristics of the bread were analyzed. The results indicated that the pH value and dough raising power of the dough decreased and the moisture content of the bread added with SBBP increased compared to that without the SBBP. The crust color of the bread did not change significantly. However, the crumb lightness value decreased and the redness and yellowness value increased respectively to the concentration of the SBBP. The texture measurement indicated that the hardness, gumminess, and chewiness of the bread increased with the addition of the SBBP. The total polyphenol content of the bread supplemented with the SBBP was increased (4.60~16.14 mg GAE/g) compare to the control (1.67 mg GAE/g). Dose-dependent, significant-high DPPH (26.86%) and ABTS (42.52%) radical scavenging activities were observed in the bread with the addition of the SBBP up to 5%. Based on these results, the optimum amount of the SBBP to add for baking bread would be 3% and the SBBP could be considered a functional agent.

Five-color bread was prepared by adding herb powder to Korean whole wheat triticum aestivum flour and the quality of baking was analyzed. The pH of the control bread was 6.15±0.12 while that of the whole wheat flour test group was 6.35±0.11, 6.29±0.12, 6.36±0.12, 6.19±0.11, and 6.01±0.13, respectively. The L value of the control bread was 67.78±0.03 and that of the whole wheat flour test group was 69.66±0.02, 60.01±0.12, 64.23±0.01, 63.34±0.01, and 61.64±0.04, respectively. The water activity was slightly increased at 2 days of storage due to the difference in water absorption and water retention. However, on the third day, the water transfer phenomenon in the bread showed water activity decrease in all wheat flour test groups. On the 1st day of the whole wheat flour test bread, the hardness values were 186.86±4.81, 165.89±3.73, 189.71±3.32, 198.38±2.19, and 184.29±3.40 g/cm2, respectively, and that of the control group was 138.84±3.72 g/cm2. The hardness of the control group and the whole wheat flour test group showed a significant difference. The internal structure of the bread in the whole wheat flour test group (100x, 500x) was not smoother than the control’s. The swelling degree of the starch particles and the cracking of the crumbs were confirmed by the adding of five-colored herbs to whole wheat flour.

This paper investigated the effects of the percentages of yeast and fermentation time as well as the top and bottom temperature of oven on the baking properties of rice bread. The specific volume of the dough decreased as the amount of added yeast and fermentation time increased. When 1.5% yeast was added at 60 min of fermentation time, the shape of the rice bread showed the largest volume, high appearance and a round shape. The top and bottom temperature of the oven on the baking characteristics of rice bread were affected by the baking time. When the top and bottom temperature of the oven at 200 and 140℃, and 200 and 170℃, the baking time was 20 min. When the top and bottom temperature of oven at 140 and 170℃, the baking time was 40 min. When the top and bottom temperature of the oven were 170 and 170℃, the shape of the rice bread indicated the largest volume, high appearance and a round shape. The results of this study revealed that the replacement of rice flour with 1.5% yeast, 60 min of fermentation time, and the top and bottom temperature of oven at 170-170℃ are effective for rice bread.

The aim of this study was to optimize the best recipe to make acorn bread containing milk as a functional food. The color value, textural, and sensory properties of the acorn bread added with 10~40% ratio of milk were measured to develop the best recipe. As a result, the L-value of color increased with the amount of milk added, but the a- and b-values decreased. As the textural measurement, the hardness increased with increasing milk added. Cohesiveness and springiness decreased, but the gumminess and brittleness increased with the addition of 20% milk, and decreased with further addition. The sensory evaluation revealed color, taste, and overall acceptances to have high scores at 20% addition of milk. Softness and chewiness were good at 10% addition. During the storage periods at room temperature, the L- and b-values increased with the addition of milk, whereas a-value decreased. In freezer storage, the L-value increased with milk content added, but the a- and b-values decreased during the storage periods. The textural properties increased during the storage at room temperature. The addition of milk decreased the cohesiveness and springiness, but the gumminess and brittleness increased significantly after one day storage. In freezer storage, all textural properties increased significantly during the storage periods, but the hardness decreased after two days storage. With the increasing amount of milk added increased the cohesiveness, springiness, and the gumminess except for four days, but decreased hardness and brittleness after two days storage. Therefore the addition of milk in acorn bread improved the textural properties significantly.

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.

In this study, bread was prepared using various amount of ‘Fuji’ apple juice, and quality and antioxidant properties investigated. Bread was prepared with water, butter, yeast, salt, sugar, wheat flour, skim milk powder and 10, 20 and 30% (w/w) ‘Fuji’ apple juice. Leavening ability and pH of dough were also investigated. Volume, pH, specific volume, baking-loss rate, chromaticity and texture were investigated as quality properties, whereas the total polyphenol content, ABTS and DPPH radical scavenging activity as the antioxidant properties of bread containing various amount of apple juice. The pH and leavening ability of dough were observed to decrease with increasing amount of apple juice. In the quality properties of bread, pH, volume, specific volume, and baking-loss rate decreased. Regarding chromaticity and texture of bread prepared with increasing amount of ‘Fuji’ apple juice, L (bright) values at crust and crumb of bread decreased, while hardness, chewiness and gumminess increased. Total polyphenol content increased with increasing amount of apple juice, while DPPH and ABTS radical scavenging activities showed no significant differences. Consequently, these results support the possible use of apple juice for baking foods in food industry, as addition of apple juice enhances the quality and antioxidant properties of bread.

This study was conducted to evaluate the characteristics of bread and the rheology of flour dough containing jochung. In the farinogram test, the addition of jochung changed water absorption, development time and mixing tolerance index for making bread As the amount of jochung increased, the water absorption, mixing tolerance index decreased and the development time increased. In the extensograph test, the degree of extension decreased with increasing of jochung content whereas degree of resistance was enhanced with addition of jochung. After fermentation treatment, the volume of the dough with 20% sucrose were less than that of the dough containing 20% of jochung. The dough with 5% jochung showed the lowest dough raising power compared to the other doughs. The bread consisting of 15% jochung showed the highest volume of loaf and specific volume. Therefore, high quality of bread can be achieved by adding jochung instead of sucrose for making bread.

The baking properties of rice bread with polydextrose (3, 6, and 9%), enzymes (0.006, 0.009, and 0.018%) and egg (1.32 and 2.64%) were investigated. The specific gravity and color (L, a, b) of the dough, as well as the appearance, color (L, a, b) and texture of the rice bread were analyzed. The springiness, chewiness, gumminess (p<0.01) and hardness (p<0.001) of the rice bread tended to increase as the amount of added polydextrose increased. Replacement of rice flour with hemicellulase, glucose oxidase and fungal amylase are effective for producing rice bread. Replacement of rice flour with 0.009% glucose oxidase and 0.006% fungal amylase had a significant effect on increasing the volume and decreasing the hardness of the rice bread (p<0.001). Replacement of rice flour with 1.32% egg white also had a significant effect on increasing the volume and decreasing the hardness of the rice bread (p<0.001). These results suggest that replacement of rice flour with 0.009% glucose oxidase and 0.006% fungal amylase, and 1.32% egg white are effective for producing rice bread with good volume and hardness.
