Mulberry fruit powder was substituted for wheat flour in pound cake recipes in amounts of 0%(control), 5%, 10%, 15%, and 20%. We measured the specific gravity of the dough, specific loaf volume, dough yield, baking loss, moisture content, pH, color, identified the texture, and conducted a sensory evaluation for each pound cake. Moisture content increased according to the amount of mulberry fruit powder, but specific gravity, dough yield, and pH decreased. Specific loaf volume and baking loss increased as the amount of mulberry fruit powder increased, but not considerably. The chromatic 'L' and 'b' values were reduced as more mulberry fruit powder was added to more pound cake, While the chromatic 'a' value increased. Texture hardness, springiness, gumminess and chewiness decreased as the pound cake contained more mulberry fruit powder. Cohesiveness did not show any considerable differences beteeen the cakes. A sensory evaluation showed a high preference for the pound cake made with 10% mulberry fruit powder.

This study examined the quality characteristics of cookies prepared with mulberry leaf powder (0, 1, 3, 5, and 7%) substituted for flour. The pH of the cookie dough decreased significantly in response to the addition of all levels of mulberry leaf powder. The spread factor of the cookies also increased significantly with increasing mulberry leaf powder content added to the cookies recipe. In addition, the Hunter's color L and a values decreased significantly with increasing mulberry leaf powder content, whereas the b value increased. According to hardness measurements, the substitution of 1~7% mulberry leaf powder resulted in increased hardness compared to the control. Moreover, the DPPH free radical scavenging activity of the cookies was increased significantly (p<0.05) with increasing levels of mulberry leaf powder. The sensory evaluation revealed cookies containing 3% to have the highest scores.

The purpose of this study was to analyze the physiological activity and antibiosis of mulberry powder by extract method. The total phenol content of mulberry powder extracted with methanol was 82.9 mg/g, while that of powder extracted with water was 46.9 mg/g. Extractions with methanol were therefore more effective than with water. The total flavonoid contents of mulberry powder extracted with methanol was 13.0 mg/g, while that of powder extracted with water was 9.4 mg/g. Also, the nitrite-scavenging ability of mulberry powder was lower than ascorbic acid and BHT. The SOD-like activity of mulberry powder extracts, natural antioxidant, and artificial antioxidant at 5 mg/mL arranged in order of decreasing concentration were ascorbic acid (98.3%) > BHT (88.1%) > water extract (9.8%) > methanol extract (3.0%). And, the OH radical scavenging activities of mulberry powder extracts and natural antioxidant at 5 mg/mL in order of decreasing concentration was ascorbic acid (97.0%) > methanol extract (46.2%) > water extract (35.8%). The antimicrobial effects of mulberry powder extracted with methanol could be detected on Bacillus cereus ($10,000{\mu}g/disc$) and Staphylococcus aureus ($10,000{\mu}g/disc$).

Mulberry pomace, a by-product obtained from mulberry juice, has not been utilized as a food material for food processing. In this study, the quality characteristics and antioxidant activities of chocolate to which mulberry pomace has been added were evaluated. Freeze-dried mulberry pomace was added to white chocolate at the level of 0, 0.5, 1.5 or 2.5%, and then the white chocolate ganache was put between two layers of dark chocolate. The moisture content and sweetness were not significantly different among treatments, but reducing sugar content was increased, according to the amount of mulberry pomace powder. The Hunter color L(lightness) and b(yellowness) values decreased, according to the mulberry pomace powder amount, whereas the a(redness) increased. The hardness increased according to the mulberry pomace powder amount. Total phenol and flavonoid contents increased, according to the mulberry pomace powder amount. Antioxidant activities(DPPH and hydroxyl radical scavenging activities) also increased, according to the mulberry pomace powder amount. The result of the sensory intensity test revealed that the scores of color, mulberry taste, hardness and chewiness were the highest in the 2.5% mulberry pomace powder added chocolate. Sensory preference test results showed that chocolate added with 1.5% mulberry pomace powder had the highest scores in color, flavor, taste, texture and overall preference. It is suggested that chocolate to which mulberry pomace powder has been added may be a functional chocolate, with high antioxidant activity.

The purpose of this study was to investigate the quality characteristics of sponge cake with various amounts of mulberry leaf powder in place of flour. The specific gravity of kneading was maintained at the different amounts of added mulberry leaf powder, which increased at ratios of 5, 10, 15, and 20 percent. The crumb decreased greatly when flour rather than mulberry leaf powder was used. As the amount of mulberry powder increased, red and yellow color decreased in both the crumb and crust. The volume and symmetry indices of the sponge cake slightly decreased when the amount of mulberry powder increased. However, uniformity was not significantly different between the samples. The specific volume of the cake decreased when the amount of the mulberry leaf powder increased. In addition, mulberry leaf powder increased the degrees of hardness and gumminess of cake, but did not show any differences for the cohesiveness and springiness of the cake texture. In the consumer acceptability test, the most favorable taste and odor were attained at the 10 percent level of mulberry leaf powder.

Mulberry leaves Julpyun(a traditional Korean rice cake) was prepared by adding Mulberry leaves powder in the ratio of 0%, 3%, 6% and 9% of rice flour, and tested for inorganic nature, physical function, chromaticity, and rheological properties. As the ratio of mulberry leaves powder increased, both the amounts of major inorganic ingredients, calcium, magnesium, and sodium, and the amounts of minor inorganic ingredients, iron, copper, and zinc, were increased proportionally. Thus, one way to increase the amounts of inorganic ingredients appeared to add mulberry leaves powder. In physical function test, control cake(0% mulberry leaves) showed the highest value in appearance and the value decreased as the amounts of mulberry leaves increased. In color, 3%-mulberry leaves-Julpyun gave the highest value followed by 0%, 6%, and 9%-Julpyun in order. The values of texture and moisture were decreased as the ratio of mulberry leaves powder increased. In rheometer test, 9%-mulberry leaves Julpyun showed the high values in hardness, cohesiveness, and brittleness. Therefore, as the amounts of mulberry leaves powder increased, the amounts of inorganic ingredients increased, but the value of physical function test decreased. 9% mulberry leaves Julpyun has the highest value of rheometer test.

This study was conducted to investigate the effect of mulberry leaf powder on the antioxidant activity and the quality characteristics of maejakgwa (a Korean traditional cookie). Maejakgwa was prepared with different amounts of mulberry leaf powder (in ratios of 0, 3, 6, 9 and 12% to the flour quantity). The antioxidant activity was estimated by DPPH free radical scavenging activity and the total phenol content in mulberry leaf powder and maejakgwa. For analyzing the quality characteristics, bulk density and the pH of the dough, moisture contents, color, texture profile analysis and sensory evaluations were measured. The total phenol contents, DPPH free radical scavenging activity, bulk density of the batter and the a values of maejakgwa significantly increased with increasing mulberry leaf powder, whereas the pH of the batter, L values and b values of the maejakgwa significantly decreased with increasing mulberry leaf powder content. Finally, the results of the acceptance test indicated that maejakgwa containing 6% mulberry leaf powder had the highest scores. From these results, we suggest that mulberry leaf is a good ingredient for increasing consumer acceptability as well as the functionality of maejakgwa.
