摘要
[Objective] To optimize solid state fermentation conditions of rapeseed meal and thus to reduce glucosinolates and neutral detergent fibers by mixed cultures of Aspergillus oryzae and Tnchoderrna viride. [ Method ] The optimal fermentation conditions were determined by single factor test and orthogonal design. [ Result J The optimum fermentation conditions are as following: inoculum weight ratio (Aspergillus oryzae vs Trichoderma vinde), 1:1 ; inoculum size, 30% ; water content, 40% ; fermentation time, 96 h; and fermentation temperature, 30℃. Under these conditions, glucosinolates were reduced by 90.71% and neutral detergent fibers were degraded by 20.65%. [ Condusion] In laboratory, solid state fermentation with Aspergillus oryzae and Trichoderrna viride can be used to produce high-quality rapeseed meal.
