Abstract
This invention discloses a mycelial composite packaging material based on Ganoderma lucidum strains and its preparation method, belonging to the field of packaging material technology. The method includes five-stage subculturing activation of Ganoderma lucidum strains using PDA medium, preparation and inoculation of soybean straw substrate, primary mold culture, secondary sealed culture, and gradient drying treatment. This invention ensures high viability and stability of the strains through five-stage subculturing, promotes free mycelial growth and surface mycelial film formation through secondary sealed culture, further improving the structural integrity and mechanical strength of the material and avoiding yellowing caused by surface water droplet accumulation. The gradient drying process effectively avoids Maillard reactions and surface scorching, while also effectively reducing shrinkage during the drying process, significantly improving the overall performance of the Ganoderma lucidum mycelium and soybean straw composite material.
