  • Recently, the incidence of cardiovascular diseases including high blood pressure and heart disease has increased with increased meat consumption in Korea. This study was performed to determine the optimal mixing ratio among ratios of 0, 1:0, 0:1, 1:1, 2:1, and 1:2 of mulberry leaf powder to mulberry fruit powder based on the anti-inflammatory effects. Then, the quality characteristics of the sauce for meat prepared with different mixing ratios (0, 1:1, 1:2, 1:3, 1:4, and 1:5) of mulberry leaf powder to mulberry fruit powder were assessed. The inhibitory effects of ML2MF1 (2:1 ratio of mulberry leaf powder to mulberry fruit powder) on NO and TNF-${\alpha}$ production were superior to those of other mixing ratios. With respect to color values of the sauce for meat prepared with different mixing ratio of mulberry leaf powder to mulberry fruit powder, as the mulberry fruit powder mixing ratios was increased, redness was increased but lightness and yellowness were decreased. The sensory evaluation of ML1MF5S (1:5 ratio of mulberry leaf powder to mulberry fruit powder) sauce for meat showed the highest score with respect to color, smell, taste, harmony with meat and the overall preference. In conclusion, as the mulberry leaf powder mixing ratio was increased, the anti-inflammatory activities were increased. But sensory evaluation scores were increased as the mulberry fruit powder mixing ratio was increased. Therefore, by performing further study, the method to increase mulberry leaf powder in the mixing ratio for improving the sensory evaluation should be provided.

  • 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.

  • The results of influence on the saccharification and $Sikhea$ by adding mulberry fruit in this study are as follows. pH was decreased with the amount of mulberry fruit increased during the saccharification period. A significant change was not found after 4 hours of saccharification. It is considered that 4-5 hours was proper for saccharification because brix increased by more than 1 brix per hour up to 4 hours while there were little change after 5 hours. L was decreased while a and b values were increased in the Hunter' value of mulberry fruit $Sikhea$. The DPPH free radical scavenging activities and SOD-like activity of mulberry fruit $Sikhea$ were increased as the addition quantity of mulberry fruit increased. Anthocynin color pigment in mulberry fruit has the inhibiting effect on microbes. The preferences of mulberry fruit $Sikhea$ were 10% < 30% < 15% < 20% < 0% < 25%, and less than 25% of mulberry fruit addition seems to be desirable. The addition of mulberry fruit will help decrease the amount of sugar to use in $Sikhea$ because the sugar level of $Sikhea$ increases with the addition of mulberry fruit. It will also improve the preference for Sihkea by giving it better color and sourness.

  • The current study examined the effects of freeze-dried mulberry fruit on disaccharidase activity in the small intestine and the lowering of blood glucose in streptozotocin (STZ)-induced diabetic rats. Sprague-Dawley male rats were randomly assigned to one normal and three streptozotocin (STZ)-induced diabetic groups. The diabetic groups were fed a mulberry fruit-free diet (DM-group), 0.3% mulberry fruit diet (DM-F group) or 0.6% mulberry fruit diet (DM-2F group). After they were fed the experimental diets for three weeks, diabetes was induced with an intraperitoneal injection of streptozotocin 50 mg/kg b.w before sacrificing 9 days later using the same experimental treatments. Analyses of anthocyanins, flavonoid and 1-deoxynojirimycin (DNJ) of lyophilized mulberry fruit were carried out and the major anthocyanins were rutin (142.5 mg), isoquercitrin (10.3 mg), quercetin (5.8 mg), morin (1.6 mg) dihydroquercetin (3.83 mg), cy-3-O-glucopyranoside (230.45 mg) and cy-3-O-rutinoside (131.5 mg) on the basis of 100 g dry weight. Total DNJ content was 2.39 mg/g dry weight of lyophilized mulberry fruit. Blood glucose level decreased in the diabetic mts fed the mulberry fruit supplement. The content of the liver glycogen increased in the diabetic mts fed the mulberry fruit supplement. Disaccharidase activity in the proximal part of the intestine, such as that of maltase, sucrase and lactase in the mulberry fruit supplementation groups, were lower than that of the DM group. These results suggest that mulberry fruit possess a suppressive effect on hyperglycemia, possibly by inhibiting the activity of disaccharidase in the small intestine of rats.

  • Semi-dried mulberry fruit can be distributed at room temperature and maintained its chewy texture and shape. It can be used for its own itself or food materials. We develop the honey coating semi-dried mulberry fruit manufacturing method through hot air dryer. After extracting the moisture from the thawing process, honey was coated and dried. Drying time for semidried mulberry fruit was shortened by manufacturing on the day of work without going through aging process. The first the mulberry fruit juice was separated from the frozen mulberry fruit at room temperature of the laboratory or in the dryer of $60{\sim}90^{\circ}C$, then the first dried by a hot air drier at $60^{\circ}C$ for 3 to 4 h. Next, it is coated with honey, which is equivalent to 20% weight of the first dried mulberry fruit, and then the second dried at a temperature of $38^{\circ}C$ for 20 ~ 30 h. The honey coating semi-dried mulberry fruit by above method was shiny on the surface and retained its shape. The moisture content was about 15% and it was confirmed that it could be stored at room temperature.

  • Using the relatively low-cost, far-infrared dryer inhibiting the destruction of a variety of physiologically active components of the mulberry fruit, we have studied to make semidry mulberry fruit that can be kept at room temperature for a long time. By adjusting the temperature of the far-infrared dryer step-by-step, we developed a semi-dry method of maintaining the shape of the mulberry fruit. In addition, by drying the coating of honey after removing the juice generated by the mulberry fruit thawing process improved the acceptability of the taste of fruit. We conducted heat treatment mulberry fruit into a $95^{\circ}C$ infrared dryer 5 hours to thaw the frozen mulberry fruit. After 10 to 20% of honey coating, the primary drying ($95^{\circ}C$, 5 hours) was implemented. then, the secondary drying was conducted after controlling the temperature of the far infrared dryer $60^{\circ}C$, for 10 hours. These manufacture process was able to obtain semi-dried mulberry fruit. Dry weight ratio and moisture content were around 25%, and around 16% level respectively. It was to enable long-term storage at room temperature. Therefore, it is suggested that the method of using the far-infrared drying machine to manufacture semi-dried mulberry fruit can be a way to improve the farm income if applied to the farm.

  • In relation to the global increase trend of obesity population, there is a demand for the development of foods having high functional activity by mass-extracting anti-obesity active substances using mulberry product such as leaf and fruit. Therefore, we evaluated the antiobesity efficacy according to varieties by using the mulberry leaves and fruit extracts. At the same time, high active varieties were selected. For this purpose, the effects of the extracts of the mulberry leaf and fruit on 3T3-L1 adipocyte differentiation were examined. As a result, in the case of mulberry leaves, the lipid accumulation inhibitory rate of 'Cheongolppong' was higher than that of the control at $500{\mu}g/ml$ treatment. And in the case of the extract of mulberry fruit, 'Daesim' showed the highest lipid accumulation inhibitory rate compared with the control at 50 times of diluted extract.
