This study was carried out to investigate the physicochemical and antioxidant properties of fermented milk with addition of hot water extract of Cordyceps militaris grown upon Tenebrio molitor. The general components of Cordyceps militaris grown upon Tenebrio molitor are moisture 10.85%, crude protein 18.44%, crude fat 2.07%, crude ash 5.46%. The DPPH radical scavenging activities of different solvents were the highest (74.81 EDA%) with hot water extract sample. The acidity of fermented milk was high with increasing amount of extracts. The pH of fermented milk reached 4.60-4.66 after 4 h of fermentation, and the number of lactic acid bacteria was highest (11.70 log CFU/mL) with 1% fermented milk. The moisture content of fermented milk showed no significant difference. In addition, contents of crude protein were not significantly different according to addition amount. Regarding Hunter's color values, L value decreased as the amount of extract increased, whereas a value and b value increased. The content of free amino acid increased with increasing amount of extract. The DPPH free radical scavenging ability and ABTS free radical scavenging ability of fermented milk were significantly different as the addition amount of extract increased. In the sensory evaluation, fermented milk containing 1% of extract showed the highest preference.

Countries of the world are competing for the collection and utilization of genetic resources, which is a resource of valueadded industrialization. We are building database of silkworm and mulberry resources with morphological, genetic characteristics data etc. Moreover, recent bioactive compound has been receiving increasing attention. So we analyzed 1-deoxynojirimycin(1-DNJ) content as a this item in addition to the basic information using 363 strains(varieties) of mulberry genetic resources. They were grown under the same environment and conditions. Mulberry leaves were collected and then freeze-dried and powdered for 1-DNJ test. As a result, 1-DNJ mean content of 363 mulberry strains was 0.176±0.077%, and the coefficient of variation (CV) was 43.5%. The variation between the strains was greatly severe. Among the tested strains, 'C1D89/29' was showed the highest content of 0.47%, whereas 'Pumbo 24' and 'Turkey E' were showed the lowest content of 0.05% respectively. The content of 1-DNJ of 16 mulberry varieties for silkworm rearing were compared. Average concentration was 0.17±0.04%, and the coefficient of variation (CV) was 22.8%. Variation among cultivars was not significant. Finally we selected 1-DNJ high-containing 11 strains. They are as follows. 'C1D89
