본 발명은 셀레늄이 고함량 포함된 달걀 및 이의 제조 방법에 관한 것이다.The present invention relates to an egg containing a high content of selenium and a method for preparing the same.

종래 셀레늄(Selenium, Se)은 1860년 마르코폴로의 '동방견문록'에서 독성이 기록되면서 오랫동안 잊혀져 있었다. 동방견문록에 따르면 셀레늄의 과잉 섭취로 말의 털과 발굽이 빠지는 치명적인 증상이 나타났다고 보고 하고 있다. 그러다가 1960년대 셀레늄 결과 관련된 연구가 활발하게 진행되었고, 1973년에는 셀레늄이 동물 체내에서 노화방지 작용인 항산화작용을 하는 글루타치온 퍼옥시다아제 효소의 필수 구성 성분임이 밝혀지게 되었다. 셀레늄은 체내에서 유해한 자유 라디칼의 수준을 낮추는 작용을 하는, 항산화계의 적절한 기능에 필요하다. 1978년에서는 세계보건기구에서 셀레늄을 필수 영양소로 인정하기까지 되었다. 셀레늄(selenium; Se)은 인체의 세포 기능의 활성화에 필수적인 미네랄로 밝혀진(Schwars and Foltz, 1957) 이후 암(Clark et al., 1996)과 바이러스성 감염(Rayman, 2000) 등과 같은 질병의 예방과 치료에 효과가 있고, 가축의 경우 결핍되면 백근증, 간장염, 심장질환, 소화관 부종, 설사 등이 발생(Kim and Mahan, 2003; Eklow et al., 1981; Chen et al., 1981)하는 것으로 알려졌다.Conventional selenium (Se) has been forgotten for a long time as toxicity was recorded in Marco Polo's 'Reviews from the East' in 1860. According to the Oriental History, it is reported that excessive intake of selenium resulted in fatal symptoms of horse hair and hooves falling out. Then, in the 1960s, studies related to selenium results were actively conducted, and in 1973, it was revealed that selenium is an essential component of the glutathione peroxidase enzyme, which acts as an antioxidant, which is an anti-aging action in the animal body. Selenium is necessary for the proper functioning of the antioxidant system, which acts to lower the level of harmful free radicals in the body. In 1978, the World Health Organization even recognized selenium as an essential nutrient. Selenium (Se) has been found to be an essential mineral for the activation of cellular functions in the human body (Schwars and Foltz, 1957), and since then, it has been used in the prevention of diseases such as cancer (Clark et al., 1996) and viral infections (Rayman, 2000). It is effective in treatment, and in the case of livestock, if it is deficient, albinism, hepatitis, heart disease, digestive tract edema, diarrhea, etc. occur (Kim and Mahan, 2003; Eklow et al., 1981; Chen et al., 1981). known

이러한 생리적 기능을 가지는 셀레늄(Se)은 최근에는 각종 식물성의 식품, 즉 채소(vegetable), 마늘(gallic), 양파(onion), 버섯류(mushrooms) 등(Gerald and Combs, 2001)과 고기(meat; Knowles et al., 2004), 우유(Knowles et al., 2004; Grace et al., 2001; Shin et al., 1999) 등과 같은 축산물을 강화시키는 연구들이 다양하게 수행되고 있다.Selenium (Se) having such a physiological function has recently been used in various plant foods, such as vegetables, garlic, onions, mushrooms, etc. (Gerald and Combs, 2001) and meat; Knowles et al ., 2004) and milk (Knowles et al ., 2004; Grace et al ., 2001; Shin et al ., 1999), etc., various studies have been conducted to fortify livestock products.

500L의 바이오리액터에 상기 표 2의 각각의 시약을 넣고 잘 혼합한다. 가성소다 또는 황산을 이용하여 pH 6.0∼ 6.5로 조정하여 멸균한다(멸균조건: 121℃, 40분). 배지가 30℃로 냉각되었을 때 클린부스내에서 미리 배양된 상기 효모, 고초균 시드를 접종한다. 이 과정에서 멸균필터를 통하여 산소를 지속적으로 공급한다. 확대배양을 위한 배양온도는 30℃로 유지하여 48시간 배양하여 발효사료를 제조하였다. 배양 전후에 무기 셀레늄의 원소와 유기셀레늄의 원소의 양을 ICP-MS를 이용하여 측정하였다. 측정결과 첨가된 무기셀레늄 원소는 유기셀레늄 원소로 84% 전환된 것을 확인하였다. 유기셀레늄의 형태는 셀레노메티오닌(selenomethionine) 또는 셀레노시스테인(selenocysteine)의 형태로 존재하고 있었다.Put each reagent in Table 2 above in a 500L bioreactor and mix well. Sterilize by adjusting the pH to 6.0-6.5 using caustic soda or sulfuric acid (sterilization conditions: 121°C, 40 minutes). When the medium is cooled to 30° C., the yeast and Bacillus subtilis seeds previously cultured in a clean booth are inoculated. During this process, oxygen is continuously supplied through the sterilization filter. The culture temperature for the expansion was maintained at 30 °C and cultured for 48 hours to prepare a fermented feed. The amounts of inorganic selenium elements and organic selenium elements before and after incubation were measured using ICP-MS. As a result of the measurement, it was confirmed that the added inorganic selenium element was converted to organic selenium element by 84%. The form of organoselenium existed in the form of selenomethionine or selenocysteine.

[실시예 2] 발효 사료 산란계 투여 시험[Example 2] Test for administration of fermented feed laying hens

상기 실시예 1를 통하여 제조된 발효사료와 미강을 중량비 1:1로 혼합하여 미강 발효사료 복합제를 제조한 후, 양계용 사료 대비 상기 미강 발효사료 복합제를 20:1의 비율로 잘 혼합하여 산란계 투여용 사료조성물을 제조하였다. 경기도 광주 유정란 생산농장에서 약 10,000마리의 양계닭을 대상으로 2주일 동안 상기 사료 조성물을 산란계의 평균 일일 사료 섭취량 기준으로 100 ~ 120g 으로 투여하였다. 2주후 생산된 계란 30개를 한국식품연구원에 의뢰하여 셀레늄의 양을 측정하였다. 시험분석 결과 2차례의 분석결과 결과 유정란에서 0.5mg/kg으로 셀레늄을 포함하고 있음을 확인하였다. 대조구인 일반계란의 경우에는 0.25 내지 0.27 mg/kg이 포함되어져 있어서, 유정란에서 셀레늄의 양이 185% 이상 증가된 것을 확인하였다. 셀레늄의 일일권장량을 0.70mg/kg으로 보았을 때, 다른 식품에서 섭취되는 것에 더하여 본 발명에 따른 계란(계란이 1개에 왕란의 경우 68 g 이고, 중란이 44- 52 g이고, 소란 44 g 이하임) 하나를 더 먹음으로서 1일일권장량을 보충할 수 있다. After preparing a rice bran fermented feed complex by mixing the fermented feed and rice bran prepared in Example 1 at a weight ratio of 1:1, the rice bran fermented feed complex was well mixed in a ratio of 20:1 to the feed for poultry and administered to laying hens. For a feed composition was prepared. The feed composition was administered in an amount of 100 to 120 g based on the average daily feed intake of laying hens for about 10,000 poultry chickens at a fertilized egg production farm in Gwangju, Gyeonggi-do for 2 weeks. After 2 weeks, 30 eggs produced were requested to the Korea Food Research Institute and the amount of selenium was measured. As a result of the test analysis, it was confirmed that 0.5 mg/kg of selenium was contained in the fertilized egg as a result of two rounds of analysis. In the case of normal eggs as a control, 0.25 to 0.27 mg/kg were included, so it was confirmed that the amount of selenium in fertilized eggs was increased by more than 185%. When the daily recommended amount of selenium is 0.70 mg/kg, eggs according to the present invention in addition to those taken from other foods (one egg is 68 g for a king egg, 44-52 g for a medium egg, 44 g or less for a small egg) Im) You can supplement the daily recommended amount by eating one more.
