Mulberry being a foliage crop is grown extensively for feeding of silkworms and are also used for cattle feeding. These loaves are highly nutritious, which contain various mineral elements and bio-molecules such as carbohydrates, proteins, lipids and other essential amino acids, etc. In the present study, deproteinized mulberry leaf juice was used for preparation of the medium for cultivation of various types of microbes. Results revealed that deproteinized mulberry leaf juice medium is best for isolation of fungi, bacteria and actinomycetes and this medium can be substituted with synthetic media, which are haying the costly ingredients for isolation and identification of bacteria, fungi and actinomycetes. Further, this deproteinized mulberry juice medium can also be used in mass multiplication of useful/beneficial microbes to enhance soil microflora to improve soil fertility and to avoid root diseases. Perspective enterprises can take up the mass multiplication/large-scale production of useful microbes such as Trichoderma, Rhizobium, Pseudomonas and Bacillus to use in mulberry and in other agricultural crops using deproteinized mulberry leaf juice.

This study was carried out to investigate the quality characteristics of yellow layer cake mulberry powder. After making yellow layer cake with mulberry powder, water activity, crumb texture, crumb color, and sensory tests were investigated. After 1 day of storage, Aw of control with weak flour did not show any significant difference, whereas those with 1, 3. 5% mulberry powder showed a significant decrease in Aw. During storage, the Aw values of yellow layer cakes containing mulberry powder were consistent. Hardness, springiness, cohesiveness, and gumminess of the yellow layer cakes containing mulberry powder all decreased compared to those of control. Hardness, springiness, cohesiveness, and gumminess all increased with storage time. Further a higher percentage of mulberry powder was associated with a lower L value, but higher a value. b values were lower in the 1% and 3% mulberry powders, but 5% showed a slightly higher b value. An increase in storage time was associated with decreased L and b values and increased a value. The micrographs of yellow layer cakes with mulberry powder showed a slightly coarser porosity than that of controls. The results of the sensory test showed that the over-all acceptability of 1% mulberry powder cake was the best.

The purpose of this study was to assess the optimum coating ratio for rice, using various ratios of mulberry leaves extract, 1.0, 1.5, and 2.0%, and to determine the optimum ratio of added water, in proportion to the total weight of mulberry rice. The moisture content of the soaked rice, and the optimum water uptake rate, moisture content of the cooked rice, as well as its blue and color values, mechanical characteristics, internal structure and sensory evaluation, were analyzed. The statistical data analyses were completed using the SAS program. The results are summarized as follows: The moisture content of mulberry rice was less than that of raw rice. The average optimum water uptake of the soaked mulberry rice at the different water temperatures, 10, 20 and 30, was 20% of the total weight of the raw mulberry rice. As for the results of the sensory evaluation,; 140% water, in proportion to the total weight of raw mulberry rice, was judged to be the optimum. The average moisture content of the cooked mulberry rice was 45∼50%, but there was no significant difference in the various coating ratios. The blue value of the cooked mulberry rice awas highest on the first day of cooking. The L- and a-values decreased with increasing coating ratio, but the b-value increased under the same conditions. As for the mechanical characteristics,; the adhesiveness, hardness and springiness decreased during 2 days of storage. The internal structure of the mulberry rice, observed by SEM, showed a close structure on increasing the coating ratios of mulberry leaves extracts. It was concluded that the optimum coating ratio of mulberry rice and ratio of added water for cooking wereas 1.5 and 140%, respectively, in proportion to the total weight of raw mulberry rice.

Chiffon cakes with 2, 4, 6, 8, or 10% of mulberry powder were made. Specific gravity and batter stability of chiffon cake batter were measured. And moisture content, color, height, weight, texture of chiffon cakes were measured. Consumers also evaluated the chiffon cakes for their liking. Specific gravity of control batter was 0.5 and there were no significant differences between control and chiffon cakes with 2, 4, 6, and 8% of the mulberry powder. The sample with 10% mulberry powder had specific gravity of 0.64 and it was significantly higher compared to the control. Stability of the batters were measured using Turbiscan and the control was the least stable whereas the batter with 2% mulberry powder was the most stable. The moisture content and weight of the cake did not differ between the control chiffon cake and cakes with mulberry powder. The height of the cake was the highest for the control cake at 7.56cm, but the differences between control, and samples with 2, 4, 6, and 8% mulberry powder were not significant. The sample with 10% mulberry powder had lower height of 6.55cm. 'L', 'a', and 'b' values of crust decreased significantly with increased content of mulberry powder. Crumb color('L' and 'b' values) decreased as mulberry powder content increased, while the 'a' value increased. Hardness significantly decreased as mulberry content increased. However, fracturability and springiness did not differ between control and sample cakes. Resilience of the control and sample cakes prepared with 2% mulberry powder were lowest, and resilience increased significantly as the amount of mulberry powder increased beyond 4%. Control cake was preferred overall by consumers, while the color, softness, and flavor of mulberry powder prepared cakes(particularly 2% powder) were specifically preferred. Mulberry flavor and astringency increased as the amount of mulberry powder increased, while sweetness did not change. The intensity of the egg flavor significantly decreased as the amount of mulberry powder increased. Intensity ratings of off-flavor did not differ among control and sample cakes. We recommend the addition of 2~6% mulberry powder to the recipe for chiffon cake.

The function of mulberry leaves and the quality of muffins including mulberry leaves were examined. The electron donating ability of both a water and ethanol extract was 40% for both at 100 ppm, 62 and 72% at 500 ppm, and 77 and 83% at 1,000 ppm respectively. These experiments showed good oxidized substance activity. The SOD-like ability of the water and ethanol extracts at 1,000, 500, and 300 ppm was 49% and 55%, 33% and 39%, and 28% and 33% respectively. These results show that the ethanol extract had higher SOD-like ability than that of the water extract. The nitrite scavenging abilities of 1,000 ppm of the mulberry leaf water extract and ethanol extract at pHs of 1.2 and 3.0 were 40.5 and 47%, and 20 and 22% respectively. The Hunter lightness value tended to be lower as the amount of added mulberry leaves increased compared to the contrast set, so the lightness level with a 7% addition was the lowest. The contrast set was the highest for redness and added mulberry leaves tended to decrease redness at 3% but tended to increase it again with additions >3%. The b-value (yellowness) showed a similar tendency as redness. Adding Mulberry leaves tended to decrease the contrast set to the lowest level, then values increased slowly to a peak at 5% added mulberry leaf and then decreased thereafter. Strength and hardness were less after increasing added mulberry leaf. Cohesiveness, springiness, gumminess and brittleness, decreased at up to 5% added mulberry leaves but the 7% addition showed the same level as the contrast set. The mulberry leaves muffins were less preferred to the contrast set in appearance and color. However, the mulberry leaf muffins were preferred to the contrast set in taste and flavor but the result was not significant. Overall the quality of the muffins with 3% added mulberry leaves was preferred over the 1% added mulberry leaf muffins.

상지(桑紙)는 우리나라에서 많이 사용된 종이였음에도 불구하고 문헌에 그의 원료에 대한 기록이 거의 없다. 양잠의 원료로서의 중요성 때문이기도 하지만 닥나무와 비슷한 형태때문일 것으로 생각된다. 특히 양잠에 유리한 수종(樹種)으로 개량되면서 종이의 원료로서의 중요성을 점차 잃어서 현재는 생산되지 않는 전통종이 가운데 하나다. 본고에서는 뽕나무의 인피를 사용하여 전통상지(傳統桑紙)를 만들고 저지(楮紙)와 함께 그 물성(物性)을 비교하여 보았다. 그 결과 섬유의 형태면에서는 섬유의 길이와 넓이의 비율이 475이며, 화학적 조성에서도 리그닌의 함량이 닥나무보다 적었으므로 종이의 원료로서 매우 우수하였다. 종이의 물성도 저지와 큰 차이가 없었다. 또 종이의 보존성을 시험한 결과 $105^{\circ}C$로 72시간, 144시간을 가열한 환경에서는 상지가 저지와 비교하여 불리하였으나, 자외선이 24시간, 100시간, 200시간 조사된 환경에서는 시간이 경과될수록 변화의 폭이 적었다. 즉 오랜기간이 경과될수록 상지는 덜 노화되며, 외관상으로도 열화가 많이 진행되지 않는 훌륭한 종이임이 밝혀졌다. 특히 실험에 사용한 상피(桑皮)가 개량종임을 감안한다면, 조선조나 그 이전에 만들어진 상지는 더 품질이 좋았을 것으로 사료된다.
