  • To investigate the detoxificative effect of tea, five kinds of tea(mulberry, anaerobic treated mulberry, green, barly tea and corm tea) were selected and determined their dotoxication activities for Cd and Pb in drinking water. The effect of tea on the removal of Cd and Pb were increased proportionally to the contents of teas. Anaerobic treated mulberry leaf tea showed stronger detoxication activity than the others. In drinking water contaminated with Cd, the removal effect of Cd was high 27% by anaerobic treated mulberry leaf tea and 14% by mulberry leaf tea as compared to green tea. Also, in drinking water with Pb, the removal effect of anaerobic treated mulberry leaf tea was the best among five kinds of tea. Pretreatment method on the removal effect of Cd was better than post-treatment method in the treatment method.

  • 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.

  • 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.

  • As the modern medicine develops, the physique and average life span are increasing. In proportion to that, modern diseases of adult people such as cancer, obesity, arteriosclerosis, cardiac disorder become great social issues. In the meantime, as the development of a new diet brings a new attention, the study is designed to examine the availability of functional food by adding Korean traditional food, soybean Dasik, mulberry leaf. For this study, mulberry leaf was added 0, 5, 10, and $15\%$ respectively to soybean Dasik in proportion to the total weight of soybean power. These are compared with the soybean Dasik itself in relation to the nutritional composition, sensory evaluation, and mechanical characteristics. The results of the research were as follows. Nutritional composition showed that mulberry leaf soybean Dasik increased Na, Ca, K, crude fiber, and ash. As for the result of sensory evaluation of mulberry leaf soybean Dasik, the followings were turned out to be good : color - $10\%$, mulberry leaf smell - $5\%,\;10\%,\;15\%$, bitterness - $5\%,\;10\%$, softness and moistness - $0\%,\;5\%,\;10\%$, and sweetness and overall quality - all the added food group. As the test results of mechanical characteristics, mulberry leaf soybean Dasik showed statistically significant difference only in the hardness, especially high on $5\%,\;10\%,\;and\;15\%$. There were no significant differences in other characteristics. In color, mulberry leaf soybean Dasik showed that L, a and b values decreased as the percentage of addition of mulberry leaf went up. Therefore, the appropriate amount of addition for the production of mulberry leaf soybean Dasik was $5\~10\%$ mulberry leaf in proportion to the weight of soybean power.

  • The in vivo digestibility of mulberry leaves (Morus alba) and the effects of the partial replacement of cotton seed with fresh mulberry leaf in rations on the performance of growing Vietnamese cattle was investigated. For the in vivo digestibility trial, twenty castrated rams of Phanrang breed (a local prolific breed) with an initial weight of 23-25 kg, were first assigned to four groups according to weight and then randomly assigned to one of four dietary treatments to determine digestibility of nutrients in mulberry leaves (M. alba), natural Bermuda grass (Cynodon dactylon), elephant grass (Pennisetum purpureum) and buffalo grass (Panicum maximum cv. TD 58). All forages were cut and chopped daily before being offered (at 120% maintenance) to the sheep. In the feeding trial, 20 Laisind (Vietnam yellow cows${\times}$Red Sindhy bulls) crossbred bulls averaged 18 month old and 184 kg were used to investigate the effect of partial replacement of cottonseed in the diet by mulberry leaves on live weight gain and feed conversion rate. The experiment was a randomized complete block design with four levels of fresh mulberry leaves which varied from 0 to 15% of total dietary dry mater and five animals per treatment over an 84 day period. The in vivo digestion trial showed the superior quality of mulberry leaves compared with the grasses. Chemical analysis indicated that mulberry leaves had the highest CP and the lowest NDF contents (22.3 and 31.1% DM, respectively) among the four forages tested. Digestibility of DM and OM of the mulberry leaf (66.4 and 71.8%, respectively) was also the highest but that of CP (58.2%) and NDF (58.4%) was the lowest of the four forages evaluated (p<0.05). Consequently, the ME value and therefore net energy (NE) and unit feed for lactation (UFL) values of the mulberry leaves, which was estimated from chemical composition and digestibility values, were the highest among the forages investigated in the present study. Results of the feeding trial showed no treatment effect on average daily gain (ADG) of the cattle. The values were 554, 583, 565 and 568 g/d for animals in the diets of 0, 5, 10, and 15% mulberry leaves inclusion, respectively. Total DM intake of the animal was not affected by the treatment when expressed as kg/animal/d. However, when adjusted for metabolic weight of the animal the DM intake was reduced (p<0.05) as whole cottonseed was replaced by mulberry leaves in the ration. When the level of mulberry leaves in the ration increased from 5 to 15% of dietary DM at the expense of whole cottonseed, CP and ME intakes of the cattle were significantly decreased (p<0.05) and the feed to gain ratio reduced by 8 to 14% as compared with the control diet (p<0.05). Mulberry leaf is a good feed ingredient for ruminants because of its high level of crude protein and high digestibility of nutrients and energy. Mulberry leaves can be efficiently used as a source of protein supplement to replace cottonseed, a more expensive animal feeds ingredient, in the diet for Vietnamese cattle.
