米曲霉发酵对棉籽壳饲用品质的影响米曲霉发酵对棉籽壳饲用品质的影响
旨在改善棉籽壳的饲用品质,研究了米曲霉TM-1发酵对棉籽壳中棉酚和纤维类物质降解、蛋白质品质提升和有益代谢产物积累的影响。结果显示:米曲霉发酵后棉籽壳中棉酚含量由645.3 mg/kg降低为137.2 mg/kg,降解率达到78.7%;发酵后棉籽壳结构松散,空隙较大,且木质素、纤维素、半纤维素、中性洗涤纤维和酸性洗涤纤维含量均明显下降,表明影响棉籽壳消化利用的结构屏障被有效降解;发酵后棉籽壳中总酸和8种有机酸含量均显著增加,其中苹果酸含量提高了49.2倍,达到734.0 mg/100 g;发酵后棉籽壳中粗蛋白质含量由12.5%增加至15.5%,酸溶蛋白占比由4.8%上升到13.5%,分子质量在...
