High-yield and high-activity black fungus dry powder as well as preparation and preparation method thereof

The invention provides high-yield and high-activity black fungus dry powder as well as a preparation and a preparation method thereof, and belongs to the technical field of biology. The invention provides black fungus dry powder which is obtained by the following steps: adding water into dry black fungus, performing soaking, performing heating, performing shredding, grinding the dry black fungus into thick liquid, and performing spray-drying or freeze-drying to obtain the black fungus dry powder. Compared with the prior art, the black fungus dry powder prepared by the technical scheme has the advantages that the yield is obviously increased, and the digestive tract reaction caused by oxytetracycline is improved. 本发明提供了一种高收率、高活性黑木耳干粉及其制剂与制备方法，属于生物技术领域。本发明提供一种黑木耳干粉通过以下方法获得，即将干黑木耳加水泡发后，加热后切丝，磨浆，喷雾干燥或冻干，得黑木耳干粉。利用本发明技术方案制得的黑木耳干粉在得率和改善土霉素所致消化道反应方面与现有技术相比，均有显著提高。
