Abstract

This study analyzed the effects of different nitrogen sources in substrate composition on the growth of Pleurotus ostreatus, as well as the subsequent changes in flavor and antioxidant activity. The T2, composed of poplar sawdust, beet pulp, cotton seed dregs, and cotton seed coat in a ratio of 40:20:20:20, exhibited the highest yield at 156.6 g. The total polyphenol content and ABTS and DPPH radical scavenging activities were 8.25 mg GAE/g, 70%, and 49%, respectively, showing higher radical scavenging activity compared to the Control and T1. Additionally, varying nitrogen content resulted in distinct aroma patterns and is presumed to influence taste profiles such as sourness, umami, and saltiness.

본 연구는 느타리 병재배시 배지 조성에 따른 질소원 차이가 자실체 생육과 그에 따른 향미 변화 및 항산화 활성에 미치는 영향을 분석하였다. 포플러 톱밥, 비트펄프, 면실박, 면실피 40:20:20:20로 혼합한 T2에서 156.6 g으로 높은 수량성을 보였으며, 총 폴리페놀 함량 및 ABTS, DPPH 라디칼 소거 활성은 8.25 mg GAE/g, 70%, 49%로 Control과 T1에 비해 높은 라디칼 소거 활성을 나타냈다. 또한, 질소함량에 따라 각기 다른 향기 패턴을 나타내며 변화를 나타내는 것 뿐만 아니라 신맛, 감칠맛, 짠맛 등 맛 패턴에 영향을 미치는 것으로 추정된다.
