研究不同生长阶段白玉菇菌糠的营养成分及其发酵饲料的制备工艺条件。结果表明，白玉菇第3潮采摘后菌糠营养成分最为丰富，粗蛋白含量最高、粗纤维含量最低，是一种潜在的动物饲料原料来源。通过响应面分析法中Plackett-Burman试验设计，筛选出对白玉菇菌糠发酵效果影响显著因素作正交试验。结果表明，白玉菇菌糠发酵饲料制备最佳工艺条件为白玉菇菌糠??玉米粉8??1、发酵温度30℃、乳酸菌??酵母菌1??2、菌液接种量2.5%。发酵后，白玉菇菌糠粗蛋白、无氮浸出物显著提高，粗纤维显著降低。此外，菌糠香味明显改善、pH下降、乳酸含量提高，菌糠感官品质得到较大改善。

This article aims to analysis the nutritional composition of spent white Hypsizygus marmoreus substrate in different growth stage and optimize its technological conditions for fermentation feed preparation. The results showed that the spent white Hypsizygus marmoreus substrate after third tide picking had the most abundant nutritional, and it had the highest crude protein content, the lowest crude fiber content, which was a potential source of animal feed raw materials. The Plackett-Burman design of response surface methodology was used to select the factors for further orthogonal test, and these factors significant influence spent white Hypsizygus marmoreus substrate fermentation. The orthogonal test results reveled that the optimal technological conditions for fermentation feed preparation of spent white Hypsizygus marmoreus substrate included spent white Hypsizygus marmoreus substrate:corn flour 8:1, fermentation temperature 30℃, lactic acid bacteria:yeast 1:2, inoculum size 2.5%. After fermentation, the crude protein and nitrogen free extract in spent white Hypsizygus marmoreus substrate was increased significantly, the crude fiber was decreased significantly. In addition, the sensory qualities of the spent mushroom substrate were improved, including the improved aroma, decreased pH and the increased content of lactic acid.
