단핵균주 간 교잡을 통해 육성된 고품질ㆍ다수확 느타리버섯“청산”의 주요특성은 다음과 같다. 가. 균사생장적온은 27∼28℃이고 버섯발생 및 생육온도는 14∼17℃이다. 나. 갓색은 진회색이고 얕은깔대기형이며 발생형태는 다발형이다. 다. 대색은 백색이고 형태는 굵고 긴형이다. 라. 버섯의 균일성에 있어서 갓색과 갓형태의 이형개체 발생은 없었고, 배양기간에서도 지역간 균일한 결과를 나타내었다. 마. 균상재배 시 초발이소요일수는 20일 내외, 자실체 생육일수는 4일이며, 수량은 농가실증시험에 평균 38 kg/3.3㎡을 나타냈다. 바. 청산느타리버섯은 균사활력이 강하며 적정생육온도에서 진회색을 띄나 적정온도이상의 재배환경에서는 갓색이 회색으로 바뀌어 품질이 저하되므로 생육온도 관리에 주의하여야 한다. 사. 발이량이 많으므로 재배 시 환기조절에 주의하여야 하며 갓이 약해 부서지기 쉬워 수확 및 포장 시 특히 주의를 요한다.

The study was carried out to investigate interrelationships among the acid, peroxide, iodine, thiobarbituric acid values, and changes of fatty acid compositions of some vegetable oils added to soybean milk. A storage temperature of 100℃ was used for the oxidation of the oils, and to determine of variation of the chemical properties and changes of the fatty acid composition, all the samples were carried out in every 8 hours for 40 hours. The changes in fatty acid compositions of the vegetable oils were measured by high performance liquid chromatography. The results obtained were as follow; 1. The acid values of the fresh soybean, corn, and palm oils added to the soybean milk were 0.05, 0.12, and 0.06, whereas those of the oils stored for 40 hours were 0.08, 0.18, and 0.09, respectively. 2. The peroxide values of the fresh soybean, corn, and palm oils added to the soybean milk were 0.3, 1.0, and 0.3, whereas those of the oils stored for 40 hours were 1.1, 1.1, and 0.9, respectively. 3. The iodine values of the fresh soybean, corn, and palm oils added to the soybean milk were 132.7, 124.1, and 57.0, whereas those of the oils stored for 40 hours were 127.3 108.3, and 52.0, respectively. 4. The thiobarbituric acid values of fresh soybean, corn, and palm oils added to the soybean milk were 0.18, 0.05, and 0.02, whereas those of the oils stored for 40 hours were 0.25, 0.19, and 0.07, respectively. 5. The percent content of the major fatty acids of the soybean, corn, and palm oils freshly added to the soybean milk were 2.3%,2.5%,and 25.2%for palmitic acid, 3.2%,3.2%,and 4.8%for stearic acid, 39.7%, 40.7%, and 59.3% for oleic acid, 49.9%, 53.0%, and 10.5% for linoleic acid, and 4.7%, 0.4%, and 0.7% for linolenic acid, respectively. Those of the oils stored for 40 hours were 2.9%, 4,5%, and 36.7% for palmitic acid, 8.5%, 6.8%, and 7.0% for stearic acid, 37.8%, 38.8%, and 49.2% for oleic acid, 46.2%, 49.5%, and 5.8% for linoleic acid, and 4.2%, 0.1%, and 0.1% for linolenic acid, respectively. The fatty acid compositions changed significantly: the amounts of the unsaturated fatty acid decreased considerably. The rsults of the present study demonstrated greater stability of the palm oil as compared with the stability of soybean oil and corn oil added to the soybean milk.

This study was carried out to investigate the biological effects of organic soybean extracts. Cellular and molecular analysis was performed to determine anti-oxidative, anti-inflammatory, anti-apoptotic, and anti-inflammatory effects of soybean extracts. First, we obtained various solvent extracts of soybean such as water, ethanol, and methanol. Molecular and cellular analysis were performed with 0.1 ㎎/ml concentration of each solvent extracts. The results of anti-oxidative, antiinflammatory and anti-apoptotic effects of organic soybean extracts were prominent. However, organic soybean extracts were not observed in anti-allergic effects determined by releasing histamine from rat mast cell line, RBL-2H3. Conclusively, organic soybean suppress inflammatory responses. In addition, organic soybean could be applied as a functional food ingredient for treatment of chronic inflammation, asthma, and atopic dermatitis with enhanced anti-inflammatory activities.
