Purpose: This study investigated quality characteristics and retarding retrogradation of sponge cake added beetroot powder. Methods: Sponge cakes were prepared using 0%, 2%, 4%, 6%, and 8% of beetroot powder. The specific capacity, baking loss, and dough yield were calculated. Moisture content and pH were also measured. Color values were assessed using a color measurement spectrophotometer. The retarding retrogradation was calculated employing the Avrami equation. Results: The specific capacity increased in parallel to the addition of beetroot powder's elevation, but baking loss significantly decreased. The dough yield was high in 6% and 8% additions however moisture content did not differ. The pH was increased in 0-4% additions. L and b-values significantly decreased according to the level of beetroot powder. For retarding retrogradation, a 4% addition had the effect of delaying the sponge cake's staling. Conclusion: These results suggested that the beetroot can be considered a good material to improve the quality characteristics, sensory properties, and after the addition of 4% of beetroot powder was able to delay staling. Therefore, so it is assumed to improve the sponge cake shelf life.

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.

Baked black soybean has great nutritional value, so it is a great potential ingredient in cake. To find an acceptable ingredient ratio, baked black soybean powder was to wheat flour in different experimental groups. The control was pure wheat flour, and the experimental groups had 0 (control), 10%, 20%, 30%, and 40% baked black soybean powder added. The baked black soybean powder consists of moisture (4.88%), crude protein (34.46%), crude fat (11.35%), crude ash (4.84%), and carbohydrates (44.47%). The specific gravity, spreadability, and baking loss increased with an increase in the amount of baked black soybean powder, but specific volume decreased. The 'L' and 'b' chromaticity values of a sponge cake decrease with increased amounts of added baked black soybean powder. The texture becomes more hard and stuff with added baked black soybean powder, but springiness decreases. A sensory test found the best experimental group to be that of 20% powder added.

Baking properties of Korean domestic wheat flour supplemented with pine pollen powder were investigated. Farinographic characteristics showed that the addition of pine pollen increased water absorption without any changes in dough development time and stability of dough in comparison with control. A higher gelatinization temperature and a lower maximum viscosity of dough on amylogram were observed with pine pollen powder addition. The addition of pine pollen powder showed decrease in redness and increases in lightness and yellowness of bread crumb. A significant increase in bread volume was observed as the pine pollen powder added more. Springiness. cohesiveness and resilience of bread were increased by pine pollen powder. Sensory evaluation of bread showed that the addition of pine pollen powder, especially at the level of 1%, enhanced color, mouth feeling, bleak and appearance without significant reduction of overall acceptability.

We evaluated chemical, sensory and mechanical properties of breads containing different amount of Paecilomyces japonica powder to provide the basic informations for the development of functional bread. The pH of dough with 2% Paecilomices japonica powder was the highest but the pH of dough with 3% Paecilomices japonica powder was the lowest. Baking loss rate of bread added 3% Paecilomices japonica powder was the lowest but that of bread added 1% Paecilomyces japonica powder was the highest in that. The result of sensory evaluation showed that bread added 1% Paecilomices japonica Powder was significantly more preferable in chewiness, mouth feel, texture quality and overall quality. Sensory properties of softness, wheat flour odor, moisture, and mouth feel were positively correlated with the acceptability. Mechanical properties of hardness and chewiness had negative correlation with sensory properties, but springiness, gumminess and brittleness had positive correlation with those. The results of various measurements and evaluations showed that the quality of bread containing the Paecilomices japonica powder could be well accepted organoleptically. And this in turn proves the possibility of functional bread by use of Paecilomices japonica.

This study investigated the quality characteristics of waffles added with coconut powder. Coconut powder was substituted into waffles at 0, 5, 10, 15, 20, and 25% weight amounts based on the total weight of wheat flour. The viscosity of batter tended to increase as the ratio of coconut powder increased whereas the measures of spreadability were not significantly changed. Baking loss rates tended to increase as the ratio of coconut powder increased while moisture contents were not significantly changed. The L-value and b-values decreased gradually while a-value increased. Among the textural characteristics hardness, springiness, chewiness, and gumminess tended to increase in proportion to the amount of coconut powder while cohesiveness and resilience were not significantly changed. The results of the sensory evaluation show that waffles made with 20% coconut powder were the most preferable in appearance, flavor, taste, texture, and overall acceptability.

In this study, Astragalus membranaceus powder was added (3, 6, 9%) during yeast bread preparation and its effect on product quality was examined. The results showed that the dough pH increased as the Astragalus membranaceus powder content increased. However, dough volume during fermentation did not differ significantly among the samples. Bread volume decreased (p<0.001) with an increasing amount of Astragalus membranaceus powder. Also, as the Astragalus membranaceus powder content increased, the Hunter’s color ‘L’ value of the crust decreased and the ‘a’ value increased, and for the crumb, the ‘L’ value decreased and the ‘a’ value increased. Textural property analysis indicated that hardness increased with an increasing amount of Astragalus membranaceus powder. However, up to the 6% level, there were no sensory attribute differences among the samples.

This study investigated the quality characteristics of the white pan breads with garlic powder. Three different powder concentration levels of 1%, 2% and 3% were added to flour to make the breads. The contents of moisture and crude fat of the breads added with garlic powder were lower than that of control group. However, ash content was not significantly different among groups. The pH increased with increasing garlic powder concentration. The weight of breads increased with increasing garlic powder concentration, while the volume and baking loss rate of breads decreased. In color values, with increase of garlic powder concentration, L value decreased, but a and b values increased. The water activity in the breads decreased by increasing garlic powder concentration was the highest in the control group. In the texture analyzer measurement, hardness of the breads increased with increases of garlic powder concentration, but springiness decreased. In the results of sensory evaluation, the quality of the 1% garlic powder breads showed the highest in taste, flavor and overall acceptability. The color, appearance, mouth feel and texture of the breads decreased with the increasing garlic powder content. From the results of this study, the white breads with 2% garlic powder content was shown to have the best quality.
