  • The purpose of this study was to investigate the characteristics of macaroons prepared using natural color materials (Opuntia ficus-indica var. saboten (Re-N), mulberry leaf (Gr-N), pumpkin (Ye-N), and cocoa powder (Br-N)) and corresponding artificial food colorants (red (Re-A), yellow (Ye-A), green (Gr-A) and brown (Br-A)). The moisture content of macaroons prepared using natural color material was higher compared to the macaroons prepared using artificial food colorant. DPPH and ABTS radical scavenging activity was similar in both types of macaroons. Lightness and redness of Re-N, Gr-N, Ye-N, and Br-N macaroons were lower than Re-A, Gr-A, Ye-A and Br-A macaroons. Yellowness of Re-N was higher because of the browning reaction. The texture profile analysis revealed lower hardness when natural color powder was employed. In the sensory evaluation, overall acceptability was not significantly different between natural colored and artificial colored macaroons. As a result, macaroons with the natural color material were softer and showed higher antioxidative activity, however, organoleptic properties were not much different when compared with macaroons with artificial colors. Apparently, it is stated that more studies on the development of macaroons with more enhanced physical functionality and good taste using natural materials should be performed.

  • Studies were carried out to report breeding procedure and characteristics of Fb, a strain of silkworm with abnormal food habit polyphagous. Selection was continued up to the 14th generation toward higher incidence of cabbage leaves feeding variants. In the autumn of 1992(7th generation), selected strain were subjected to severe selection by feeding them on artificial diet that did not contain mulberry leaf powder. The results were clearly positive and reached to higher than 95% of cabbage feeding in the 14th generation. This strain was first discovered by feeding cabbage leaves, but later they were observed to eat some kind of plants like lettuce, Chinese cabbage, radish, beet, apple, persimmon, pear, etc. As described above the procedure, cabbage feeding trait was clearly heritable. The strain responsible for this traits was named Fb.

  • Microbiological populations and the sterility of commercial powdered products treated with gamma irradiation at 0~10 kGy were investigated before using them as ingredients for a non-cooked Saengsik product. We evaluated a total of 14 powdered products: 8 powdered cereals, 3 powdered tubers, and 3 powdered leafy vegetables. The total numbers of bacterial populations in non-irradiated powdered cereals, tubers, and leafy vegetables were 2.7~6.9, 5.6~6.0, and $5.3{\sim}6.8\;log\; CFU{\cdot}g^{-1}$, respectively. Moreover, coliform bacteria were not indicated in adlay, millet, germinated brown rice, soybean, and mulberry leaves powder within detection limit ($2.0\;log\; CFU{\cdot}g^{-1}$). The number of Bacillus cereus exceeded $3.0\;log\; CFU{\cdot}g^{-1}$ (the maximum limit for Saengsik products) in all samples, excluding perilla seeds, buckwheat, barley, oat, potato, and Jerusalem artichoke powder. However, a dose of 6 kGy of gamma irradiation reduced the microbiological populations in all samples, and all the powdered products met the microbial requirements for Saengsik products. Futhermore, it was confirmed that all microorganisms in the 9 powdered products, except fermented brown rice, sweet potatoes, and 3 leafy vegetables, were sterilized by 10 kGy of gamma irradiation.

  • The intent of this research is to acquire some basic informations about formulation of the viral pesticide, Hyphantria cunea nuclear polyhedrosis virus and its virulence under field condition. The nuclear polyhedrosis virus was formulated as wettable powder using spreader, sticker and U.V. protector. The formulated product and aqueous virus were diluted with water at the concentration of 1${\times}$106PIB/ml and sprayed on mulberry leaves in the field. The leaves were fed with 3rd instar larvae of H. cunea to determine the inactivation period of the viral pesticides. The aqueous virus was completely inactivated on 5th day after spray, while the formulated one showed a spare mortality to the larvae even on 20th day after spray. In field application test, The fromulated and aqueous virus were sprayed on individual mulberry tree and 3rd instar laevae of H. cunea were fed on the trees. The mortality of the larvae one day after spray of the formulated and aqueous virus were about 50% and 40%, respectively. The formulated virus exhibited a persistent virulence to the larvae up to 9th day after spray, which the mortality was approximately 30%. The residual virulence of the formulated and aqueous virus was extended up to 4th day and 2nd day after spray, respectively.

  • We investigated the effect of dietary mulberry leaf powder (MP) on loperamide-induced constipation in rats. Male Sprague-Dawley rats were given MP in their diets at a concentration of 0% 5% and 10% for 33 days. Rats were divided into 4 groups: normal diet group (NOR), normal diet and loperamide treated group (MPL0), 5% MP and loperamide treated group (MPL5), and 10% MP and loperamide treated group (MPL10). Constipation was induced by subcutaneous injection of loperamide (1.5 mg/kg body weight/day) for the final 5 days of the experiment Supplemental MP had no effect on the food efficiency ratio, but it reduced body weight gain and food intake in a concentration dependent manner. Administration of loperamide decreased food intake. MP had a concentration-dependent effect on decreasing total cholesterol, LDL-cholesterol, and triglycerides and on increasing HDL-cholesterol. Loperamide had no significant effect on serum lipid profiles. Loperamide decreased the number and wet weight of fecal pellets and fecal water content MP increased the number and wet weight of fecal pellets and fecal water content in a dose-dependent manner. In addition, MP increased gut transit time and transit speed, and the guts of mts treated with MP plus loperamide were longer than those of mts treated with loperamide alone. These results indicate that MP is an effective treatment for constipation.

  • In Korea, there are many kinds of functional foods to manage diabetes, however, they have not been evaluated or investigated systematically. The purpose of this study was to investigate the status of recognition and intake of functional foods among diabetic patients. The study subjects were 307 patients(male 135, female 172), who diagnosed with type 2 diabetes at Seoul National University of Bundang Hospital. Questionnaire survey was done from July to October, 2004 for the characteristics of patients and factors related to the use of functional foods. The mean age of the subjects was 64$\pm$10.2 years, and the mean duration of disease was 9.5$\pm$8.90 years. Approximately 49.8% of the subjects had experience to use functional foods at least once in past. Total number of functional foods used were 56 types. Red ginseng was used most frequently(27.9%), then followed by Silkworm powder(13.6%), Vitamin supplements(10.4%), Mulberry tree(7.1%), Cordyceps sinensis(6.8%) and Ginseng(4.2%). Functional foods were introduced by their friends.relatives(38.4%), family(29.1%), internet(13.9%), and the mass media(10.6%). Among respondents, 94.7% took functional foods with conventional diet therapies(diet, exercise and medication). The purpose of functional food use was to control blood glucose level(49.0%), to relieve fatigue and improve stamina(19.9%), to treat and prevent a disease(17.2%) and to help blood circulation(7.9%). Upon the question of further recommendation of functional foods to others, 74.8% of the subjects answered negative response. However, 12.6% of the subjects showed the further intention of using new product. Therefore, to guide the appropriate use of functional foods for diabetic patients, diabetic educator should provide the knowledge of the efficacy of functional foods and the desirable guidelines.

  • This study has been carried out to investigate the effect of protein components of a diet on the increasing of larval body weight and diet efficiency, as well as the amylase activity of larval digestive juices during the 5th instar. Defending on the amounts of soybean meal as a protein source, the six different kind of artificial diets containing mulberry leaf powder fed to the larvae. The results obtained may be summarized as follows: 1. As the protein components of the diet were increased, the amount of increased larval body weight was also increased. 2. As the protein components of the diet were increased, both the cocoon weight and cocoon layer weight were also increased. 3. As the protein components of the diet were increased, both the amount of diet digested and coefficient of digestibility were also increased. 4. As the protein components of the diet were increased, the diet efficiency of larvae were also increased. 5. But the experimenters could not observe any correlation between the increase of protein components of a diet and the amylase activity of the digestive juices.

  • The mulberry silkworm, Bombyx mori has been one of the most important domestic animals which have provided with silk fibers for weaving fabrics and a food for a protein and lipid source. In addition, various health improvement effects of diverse silkworm larval powders were reported. Recently we found that steamed and freeze-dried mature silkworm larval powder (SMSP) generated using white-jade (also known as Backokjam) silkworm variety extended healthspan and increased resistance to Parkinson's disease in animal models. Because the colors of cocoons in silkworm varieties were caused by altered signal transduction pathways transporting phytochemicals from intestinal lumens to silk glands, we performed the proximate, amino acid, mineral, carbohydrates, fatty acid, and cholesterol composition analyses of SMSPs of 3 silkworm varieties which were weaving light yellow, golden, and red cocoons. Although most of nutrient compositions among 3 SMSPs were similar, there were significant differences in certain amino acids, minerals, and fatty acid compositions. Red silk silkworm (RS)-SMSP had higher contents of crude proteins and total amino acids than other SMSPs. In addition, the ratio of n-3/n-6 unsaturated fatty acids were higher than the other SMSPs. In contrast Golden silk silkworm (GS)-SMSP had higher ratio of potassium/sodium than the other SMSPs. These nutrient analysis results suggested that 3 SMSPs might have common and unique health improvement effects. Thus, further studies in the functionalities of the 3 SMSPs will reveal unknown their health improvements effects.
