흰쥐에게 뽕잎을 4주동안 투여하여 장기능에 미치는 영향을 알아본 결과, 사료이용효율은 10% 투여구에서 14% 감소되었고, 장 통과시간은 1% 투여구에서 16%, 10% 투여구에서 21% 빨라졌다. 장의 길이는 1% 투여구에서 10%, 10% 투여구에서 11% 증가되었고, 장 통과속도는 1% 투여구에서 30%, 10% 투여구에서 40% 빨라졌다. 변의 pH는 대조구가 6.91인데 비해 1% 투여구는 6.07, 10% 투여구는 5.95로서 뽕잎 투여량이 증가함에 따라 변의 pH는 점차 낮아졌다. 변량은 1% 투여구에서 57%, 10% 투여구에서 91% 증가되었다. 변중의 무기성분 중에서 K의 함량이 50% 증가하였으나, 이는 뽕잎 중에 K함량이 많기 때문으로 생각된다. This experiment was carried out to investigate the effects of dietary mulberry leaf powder on gastrointestinal function of rats. Plot containing one and ten percent mulberry leaf powder was supplied with rats. The food efficiency ratio (FER) of rat fed with 10% mulberry leaf powder was decreased 14%. The transit time of rat fed with 1% and 10% mulberry leaf was faster 16% and 21% than that of control respectively. Intestine length was increased 10% and 11% at 1% and 10% dietary mulberry leaf respectively. The transit speed was faster 30% at 1% dieatry mulberry leaf than that of control. The pH of rat's feces suplied with mulberry leaf was lower than that of control. The amount of daily rat's feces fed mulberry leaf was much than that of control. As above results, we suggest that mulberry leaf was evaluated to improve the function of rat's gastrointestine.

In this study, matured silkworm hemolymph was studied for inhibitory effect on melanin formation, tyrosinase activities. A matured silkworm hemolymph mass purification method was developed and some of suppressing melanin formation effects were investigated, too. As a result, the advanced purification method was higher in yield rate than existing one by 53%. A free radical scavenging activity of hemolymph was higher than sericin on the market (IC50, 202.9 ± 33.1) and lower than vitamin C (0.57 ± 0.02) by 6.4 ± 0.3 μg/mL. An inhibitory effect on melanin synthesis was higher in hemolymph compared to Morus bark and arbutin by 9.15% and 11.56%, respectively. An inhibitory effect on tyrosinase activity was higher in hemolymph than Morus bark and lower than arbutin. Effect of hemolymph 45 μg/mL on suppressing of tyrosinase was almost 90%. Thus, these results suggest that hemolymph of matured silkworm may have beneficial properties as a material for cosmetics.

작잠 누에고치를 정련한 후 질산칼슘4수화물의 용융액을 사용하여 재생 작잠 실크피브로인 스펀지를 제조하였다. 작잠 실크피브로인은 280 nm에서 tyrosine 잔기 등에 기인한 흡광대를 나타내었다. 작잠 실크피브로인 스펀지를 에탄올 농도별로 처리한 후 구조 전이를 관찰한 결과 80%에탄올 처리시에는 β-sheet 구조(700 cm-1), α-helix 구조 (625 cm-1), 그리고 random coil (660 cm-1) 구조가 공존하는 것으로 나타났다. 또한 작잠 실크피브로인을 이용한 in vitro 상처회복실험 결과 실크피브로인의 첨가에 의하여 상처회복 효과가 인정되었다. Regenerated Antheraea pernyi silk sponge was prepared using calcium nitrate 4 hydrate melt and examined the conformational changes treated with aqueous ethanol solution. The conformation of silk sponges was changed from random coil structure to β-sheet and α-helix conformation with low ethanol concentration (50 ~ 70%). On the other hand, that of silk sponges with 80% ethanol treatment showed β-sheet (700 cm?1), α-helix (625 cm?1), and random coil (660 cm?1) specific peaks. Wound healing effect in vitro was observed by cytoslective wound healing kit. Therefore, regenerated Antheraea pernyi silk sponges might be used as promising wound dressing materials.

Antheraea pernyi silkworm is one of typical wild silkworms, which spins a tawny color cocoon. The cocoon has been used as a resource for textile material due to strong chemical stability and good mechanical properties. In this study, to increase the solubility efficiency of A. pernyi silk fibroin, the composition of dissolution solvent were examined. Calcium chloride tertiary system, normally used for dissolution of Bombyx mori silk fibroin, does not act on A. pernyi silk fibroin. Calcium nitrate system dissolves A. pernyi silk fibroin, and calcium nitrate ethanol system do more easily than calcium nitrate system. Amino acid composition of A. pernyi silk fibroin obtained after dissolution is mainly composed of alanine, glycine, and serine. A. pernyi silk fibroin would be used for non-textile applications near future.

In order to evaluate the protective effects of extracts of Mori cortex radicis on carbon tetrachloride induced hepatotoxicity, glutamic oxaloacetic transaminase, glutamic pyruvic transaminase, lactic dehydrogenase, malondialdehyde values and glutathione S-transferase activity were measured in ICR mice. The activities of serum aminotransferase and the hepatic content of lipid peroxide after carbon tetrachloride-treatment were markedly increased than normal control but those levels were significantly decreased by the treatment of butanol fraction of Mori cortex radicis mathanol extract. Glutathione S-transferase activity was decreased by carbon tetrachloride than control, but that also inhibited by the treatment of butanol fraction of Mori cortex radicis methanol extract. These results demonstrate a possible hepatoprotective role of extracts of Mori cortex radicis against CCl4-induced hepatoxicity in vivo.

장수풍뎅이 유충은 쌍별귀뚜라미와 갈색거저리 및 흰점박이꽃무지 유충과 함께 국내 식품의약품안전처의 식품공전에 일반식품원료로 등록되었다. 이에 곤충에 대한 종합적인 관리 시스템 개발이 요구되고, 이와 함께 양질의 곤충을 대량생산하기 위한 위생적이고 안전한 식용곤충 전용 먹이원 개발 등과 관련된 연구를 지속적으로 수행할 필요가 있다. 식품가공 부산물은 단백질, 지질, 무기질 및 기타 여러 가지 생리활성 물질을 함유하고 있어 가축등 동물 사료의 대체 에너지원으로 활용되고 있다. 따라서 본 연구에서는 감귤박, 비지박, 대두박, 맥주박 등 4종의 식품가공 부산물을 첨가한 먹이원 급여에 따른 장수풍뎅이 유충에 미치는 효과를 비교하였다. 장수풍뎅이 3령유충에 10% 맥주박을 첨가한 먹이원을 급여했을 때 가장 높은 생존율을 보였고, 유충의 무게 또한 대조구 대비 약 26% 증가된 것으로 나타났다. 유충기간에 있어서도 10% 맥주박을 첨가했을 때 약 120일로 대조구보다 28일 이상 단축되는 것을 확인하였다. 뿐만 아니라 10% 맥주박 첨가 실험구의 용무게와 용화율이 가장 높게 나타나는 것으로 보아 맥주박이 장수풍뎅이 사육용 사료 소재로서 충분히 활용될 가치가 있을 것으로 생각된다. 더불어 맥주박은 시중에서 쉽고 저렴하게 구매할 수 있어 곤충사육 농가에서 손쉽게 활용할 수 있으며, 식품가공 부산물을 친환경적으로 처리하고 식용곤충을 안전하고 경제적으로 사육하는 데 도움이 될 것으로 기대된다. Edible insects have recently been increasingly promoted as a source of protein. As the number of farms rearing these insect increases, it is important to develop safe and nutritious feed sources to improve their commercial quality. The aim of the current study was to determine the effect of food by-products as feed supplements for the Korean rhinoceros beetle, Allomyrina dichotoma, which has been registered as a general food ingredient in Korea. We compared the effects of waste citrus peel, soybean curd cake, soybean oil meal, and brewers’ dried grain on the growth of third instar larvae of A. dichotoma. Groups of larvae were fed with fermented sawdust and nine different combinations of the above by-products and the effects on their growth were measured until pupation. The highest survival rate was with feed supplemented with 10% brewers’ dried grain (66.7%, p<0.05), and these larvae were also 26% heavier (p<0.05) than the control group that received no supplementation. In the 10% brewers’ dried grain group, the larval period of third instar was shortened by almost 28 days (p<0.01) compared to the control group. Of all the groups, only that which was fed the brewers’ dried grain supplement showed more than a 90% pupation rate (p<0.05). Therefore, brewers’ dried grain may be useful as a source of feed for A. dichotoma.

가축사료를 첨가한 먹이원의 급여가 부식성 식용곤충의 생육에 미치는 영향

송명하(Myung-Ha Song),이희삼(Heui-Sam Lee),박관호(Kwanho Park) 한국생명과학회 2018 생명과학회지 Vol.28 No.5

곤충은 식량·기능성 소재·농업자재 등 미래의 농업자원으로 유망하며, 지속적인 시장성장이 예상되고 있다. 또한 갈색거저리 유충, 쌍별귀뚜라미, 흰점박이꽃무지 및 장수풍뎅이의 유충이 일반식품원료로 인정됨에 따라 식용곤충에 대한 관심이 높아지고, 이에 대량생산을 위한 사육기술의 표준화 및 먹이원 개발에 관한 연구가 요구되고 있다. 본 연구는 흰점박이꽃무지와 장수풍뎅이 유충의 발육촉진 효과를 확인하기 위해 애견사료 및 양돈사료와 같은 시판 중인 가축사료와 밀기울을 첨가한 발효톱밥을 이용하였다. 밀기울 첨가 처리구는 흰점박이꽃무지와 장수풍뎅이의 생존율과 증체율이 현저히 낮은 수준으로 곤충 먹이원의 소재로 사용되기에 부적합한 발육양상을 보였다. 애견사료 및 양돈사료를 첨가한 먹이원을 급여하였을 때 흰점박이꽃무지와 장수풍뎅이 모두에서 유충의 생존율 및 증체율이 높고 유충기간이 단축되는 것으로 나타났다. 특히, 애견사료 5% 첨가 조건에서 흰점박이꽃무지 유충의 증체율은 초기 무게와 대비하여 179.2%로 가장 높았고, 장수풍뎅이 유충의 증체율은 애견사료 2.5% 첨가 조건에서 299.9%로 가장 높았다. 또한, 애견사료 2.5% 첨가 사료를 급여했을 때 흰점박이꽃무지와 장수풍뎅이의 유충기간은 약 67일과 116일로 기본 발효톱밥을 급여한 대조구에 비해 40일 이상 짧게 조사되었다. 따라서 가축사료는 부식성 식용곤충에 우수한 발육 효과를 나타내는 곤충 먹이원의 소재로서 활용될 수 있을 것으로 기대된다. The insect industry is a promising agricultural resource and expected to grow steadily. In Korea, Gryllus bimaculatus and the larvae of Tenebrio molior, Protaetia brevitarsis, and Allomyrina dichotoma were listed as general food ingredients. As interest in these edible insects increases, rearing techniques and nutritious food sources are needed for mass production. In this study, wheat bran, dog feed, and pig feed were investigated for their effects on the larval growth of P. brevitarsis and A. dichotoma. When fermented sawdust with 30% wheat bran was used, the larval survival rate of P. brevitarsis and A. dichotoma (p=0.244341 and p=0.007966, respectively) and growth rate (p=0.001400 and p=0.000051, respectively) were significantly lower than those of the control (fermented sawdust with no supplement). Therefore, fermented sawdust with a high density of wheat bran was inappropriate for both insects. When fed fermented sawdust with 2.5 or 5% of dog and pig feed, the survival rate and growth rate of the larvae were higher than those of the control. Interestingly, the maximum larval weight with 2.5% dog feed was increased by 3.35±0.10 g and 32.59±0.79 g for P. brevitarsis and A. dichotoma, respectively. In addition, the larval period of both was shorter than that of the control by 40 days or more. Therefore, it is considered that animal feed can be used as a feed source for these edible insects.
