초록

최근 다양한 언론매체 및 국내외 연구논문들을 통해 꽃송이버섯의 기능성이 부각되고 있다. 이에 꽃송이버섯의 농가 대량재배 일반화를 위하여 최적톱밥 입자크기 및 ${\beta}$-glucan 함량이 높은 재배법 연구를 수행한 결과 T7 (1~2 mm 25%, 2~4 mm 50%, 4 mm 이상 25%) 배지와 같이 입자크기가 일정비율로 혼합된 배지에서 $11.5{\pm}1.0$ cm/44 days로 비교적 우수한 균사생장을 보였으며 자실체생산 역시 대조구보다 높은 $142.9{\pm}17.7g$의 생중량으로 상품성이 있는 꽃부분이 85%의 비율을 차지하였다. 배지조성 조건에 따른 ${\beta}$-glucan 함량은 모든 자실체에서 꽃부분에 비해 기부가 1.4~2.4배의 높은 함량을 보였고 이 중 이스트 300 ppm이 첨가된 PCF300 (미송 + 옥수수분말 + 소맥분 + 이스트 300 ppm) 배지의 꽃송이버섯 기부가 59.5%로 가장 높은 ${\beta}$-glucan 함량을 나타냈다. 그러나 꽃부분에서는 비교적 낮은 33.0%의 함량을 보여 꽃부분의 ${\beta}$-glucan 함량을 높일 수 있는 추가적인 연구가 필요할 것으로 사료된다. 따라서 본 연구결과를 토대로 꽃송이버섯 재배시 T7조건인 1~2 mm 미송톱밥 25%, 2~4 mm 미송톱밥 50%, 4 mm 이상 미송톱밥 25%의 비율로 톱밥입자 크기를 조절한후 옥수수분말과 소맥분을 첨가하여 배지조제후 이스트 300 ppm첨가하면 ${\beta}$-glucan 함량이 높은 꽃송이버섯 생산이 가능할 것으로 사료된다.

Functional effects of cauliflower mushroom (Sparassis latifolia) have been magnified by various media and internal and external research papers, recently. So, optimum condition of wood chip particle size and cultivation method of high ${\beta}$-glucan content for bulk cultivation generalization of cauliflower mushroom farms researched. As a result, T7 (1~2 mm 25%, 2~4 mm 50%, over 4 mm 25%) media as mixed media of certain ratio of particle size, showed excellent growth at $11.5{\pm}1.0$ cm / 44 days. Also, production of fruit body found higher than control and marketable pileus part took 85% ratio. The ${\beta}$-glucan content at media composition condition showed 1.4~2.4 times higher content in stipe part than pileus part. Also, PCF300 medium found 59.5% highest ${\beta}$-glucan content in stipe part. While ${\beta}$-glucan content showed 33.0% low content in pileus part. Therefore it needed additional study that ${\beta}$-glucan content improved in pileus part. In conclusion, production of high ${\beta}$-glucan content cauliflower mushroom was possible by T7 condition (wood chip particle size: 1~2 mm 25%, 2~4 mm 50% and over 4 mm 25%, composition: corn powder, flour and 300 ppm yeast).
