This study was carried out to know the substitute effect of Yacto (leaf mold compost) on popped rice hulls compost (PRHC) in Yang-jik nursery bed of Panax ginseng. PRHC was mixed with Yacto as 50:50 ratio, and 1 ~ 2% of the mixed oil cake, rice bran and urea were also added to promote decaying the mixed compost. The mixed compost made by PRHC and Yacto was showed that positive effect on the growth of ginseng seedling when it was mixed with 1% of oil cake and rice bran, and 2% of mixed oil cake. But addition to the 2% of urea in the mixture of PRHC and Yacto was not positive effect on the growth of ginseng seedling. Root yield of the mixed compost was similar to that of conventional compost by made 100% of Yacto. Therefore, the mixed compost can substitute for Yacto when PRHC and Yacto were mixed by 50:50 ratio and added 1% of oil cake and rice bran.

The white-spotted chafer, Protaetia brevitarsis (Coleoptera: Scarabaeidae), is an economically important insect in Korea. Traditionally, it has been regarded as a medicine for preventing liver-related diseases and suppressing liver cancer. Recently, this beetle was enlisted as a temporal food ingredient by Korean Ministry of Food and Drug Safety. Therefore, this beetle is focused as a one of the important insects that are commercially reared and sold in Korea. As the economic importance of this beetle is growing, the suitable rearing conditions are needed for more detailed investigation. In this study, we compared three temperature conditions and two food additives, rice chaff and soybean cake, for its effects on the body weight change of third instar larvae of P. brevitarsis. Temperature is a major environmental factor that has tremendous effects on rearing insects. In additions, rice chaff and soybean cake are byproducts of other agricultural activities. Therefore, it is easy to get, and the price is comparatively low. However, they still have meaningful amount of nutrients. With four different kinds of feed and three temperature conditions on the third instar larvae of beetles, the body weight change was tracked for 14 wk. We concluded that 27.5℃ is the optimal temperature to rear the third instar larvae among three temperatures (25, 27.5, and 30℃). Among four different feeds, conventional fermented oak saw dust with rice chaff and soybean cake was the best feed for larval weight gain during 14 wk. However, feed with soybean cake at 30 ℃ was the best condition for rearing P. brevitarsis larvae when temperatures and feeds were compared at the same time.

Ethanol production by the simultaneous saccharification and fermentation (SSF) of low-value rice wine cake (RWC) without cooking was investigated. RWC is the filtered solid waste of fermented rice wine mash and contains 53% raw starch. For the SSF, the RWC slurry was mixed with the raw-starch-digesting enzyme of Rhizopus sp. and yeast, where the yeast strain was selected from 300 strains and identified as Saccharomyces cerevisiae KV25. The highest efficiency (94%) of ethanol production was achieved when the uncooked RWC slurry contained 23.03% starch. The optimal SSF conditions were determined as 1.125 units of the raw-starch-digesting enzyme per gram of RWC, a fermentation temperature of $30^{\circ}C$, slurry pH of 4.5, 36-h-old seeding culture, initial yeast cell number of $2{\times}10^7$ per ml of slurry, 17 mM of urea as the nitrogen additive, 0.25 mM of $Cu^{2+}$ as the metal ion additive, and a fermentation time of 90 h. Under these optimal conditions, the ethanol production resulting from the SSF of the uncooked RWC slurry was improved to 16.8% (v/v) from 15.1% (v/v) of pre-optimization.

To encourage rice consumption, this study investigated the quality characteristics of fish cakes containing four different amounts (0%: control, 50%, 75%, 100%) of rice flour. The moisture and pH of fish cake dough and fat contents, color values, folding score, texture profiles and consumer acceptability of fried fish cakes containing rice flour were measured. There were no significant difference on moisture and pH of fish cake dough containing rice flour. There was significant decrease in terms of fat contents, folding score of the fish cakes with increasing rice flour(p<.05). While a and b values were increased, L value decreased significantly, as the ratio of rice flour increased(p<.05). Hardness, cohesiveness, gumminess and chewiness of fish cakes with rice flour decreased significantly (p<.05), but no significant difference in springiness. There were no significant differences in overall acceptance, appearance, flavor, color and taste between the control group and treatment groups(p<.05). Texture was decreased significantly as the rice flour increased(p<.05). This study suggests that adding fifty percent rice flour to fish cakes could be a good way to increasing rice flour without decreasing texture acceptability.

Physicochemical and sensory characteristics of pound cakes containing Angelica gigas NAKAI(Korean Angelica) with various levels of rice flour were investigated in this study. There were significant differences in the specific gravity of dough, and it had the lowest value of 0.848 in the control group. The weight of pound cakes was significantly increased by addition of rice flour, but the volume, specific volume and baking loss rate were significantly decreased by addition of rice flour. The moisture content and pH of pound cakes were found to increase with increasing rice flour content. DPPH radical scavenging activity of the control group was 51.02%, whereas pound cakes with rice flour ranged from 51.90~55.75%. The L value of brightness was increased, but a and b values were decreased significantly by addition of rice flour. In all of items of texture, the control group was higher than those of the pound cakes prepared with various levels of rice flour. Sensory evaluation scores in terms of appearance, flavor, taste, texture and overall preference for pound cakes showed that 50% and 75% substituted sample groups were higher than those of the other groups. The results of this study suggest that addition of 50~75% rice flour is the best substitution ratio for Korean Angelica pound cakes.
