() is widely recognized for its bioactive compounds and associated health benefits. However, due to its delicate nature, conventional chilled storage often results in the rapid degradation of valuable compounds, leading to loss of nutritional value and overall quality. This study integrated and evaluated comprehensive strategies: three gas-conditioning and two light-based preservation methods for maintaining both quality and nutritional integrity during 12-day chilled storage at 4 °C. The results revealed that vacuum packaging significantly inhibited weight loss (3.49%) compared to in the control group (10.77%) and preserved sensory quality ( < 0.05). UV-based interventions notably suppressed polyphenol oxidase and tyrosinase activities by 36.4% and 29.7%, respectively ( < 0.05). Modified atmosphere packaging (MAP) with 80% N and 20% CO (MAP-NCO) maintained higher levels of cordycepin (1.77 µg/g) and preserved energy charge above 0.7 throughout storage. The results suggest that MAP-based treatments are superior methods for the chilled storage of , with diverse advantages and their corresponding shelf lives associated with different gas compositions.
（某物质）因其生物活性化合物及相关健康益处而广受认可。然而，由于其性质脆弱，传统冷藏储存往往会导致有价值的化合物迅速降解，从而造成营养价值和整体品质的损失。本研究整合并评估了综合策略：三种气体调节和两种基于光照的保鲜方法，用于在4℃下12天的冷藏储存期间维持品质和营养完整性。结果显示，与对照组（10.77%）相比，真空包装显著抑制了重量损失（3.49%）并保持了感官品质（P<0.05）。基于紫外线的干预措施分别显著抑制了多酚氧化酶和酪氨酸酶活性36.4%和29.7%（P<0.05）。含有80%氮气和20%二氧化碳的气调包装（MAP-NCO）在整个储存过程中保持了较高水平的虫草素（1.77μg/g），并将能荷保持在0.7以上。结果表明，基于气调包装的处理方法是（某物质）冷藏储存的优越方法，具有不同的优势及其与不同气体组成相关的相应保质期。
