ẢNH HƯỞNG CỦA CƠ CHẤT NUÔI TRỒNG ĐẾN NĂNG SUẤT NẤM ĐẦU KHỈ (Hericium erinaceus) VÀ LỰA CHỌN CHẾ ĐỘ SẤY NGUYÊN LIỆU PHÙ HỢP

Monkey head mushroom (Hericium erinaceus) is a medicinal mushroom with high therapeutic value; however, research on its cultivation and processing in Vietnam remains limited compared to other mushrooms such as lingzhi or wood ear mushroom. This study aimed to evaluate the effects of cultivation substrates and drying conditions on the yield and quality, respectively, of H. erinaceus. The results demonstrated that substrate composition significantly influenced mycelial growth and fruiting body formation. Notably, strain He-2 did not form fruiting body primordia on substrates lacking sawdust. The substrate formulation containing 89% sawdust, 10% rice bran, and 1% CaCO3 yielded the highest biological efficiency (51.80%), followed by the formulation with 20% cotton waste, 69% sawdust, 10% rice bran, and 1% CaCO3 (51.28%). Regarding drying conditions, the suitable condition was identified as drying at 35°C with 75% ventilation for the first 12 hours and 25% thereafter, which effectively preserved polysaccharide content and total amino acids. These findings contribute to the development of an improved cultivation and processing strategy for enhancing both productivity and medicinal quality of H. erinaceus
