摘　　要：采用黑曲霉为菌种,通过单因素试验,获得了苹果渣发酵的适宜工艺条件:尿素添加量为7%,料水比1∶1,温度30℃,发酵时间5d,接种量1%,pH值自然。在已确定的工艺条件的基础上,进行了工业化模拟试验。结果表明,当发酵料层厚度为5mm、动力通风时,发酵产物真蛋白含量达到14.09%,蛋白质含量明显提高。With Aspergillus.niger strains,the optimal condition for the fermentation of pomace into feeding-protein was obtained:the amount of carbamide was 7%. the ratio of water to material 1:1,cultivate temperature 30℃,cultune time 4～5d.inoculant volume 1% and nature pH. In addition,the conditions of mass-productiion were simulated. The results showed that 5mm thickness of medium with motorized aeration was the better condition.The content of pure protein reached14.09%.the nutrition value of protein was improved greatly.
