| 中文摘要: |
| 花生粕存在黄曲霉毒素B1（AFB1）易超标、非淀粉多糖含量高和蛋白质品质不佳等缺陷，利用微生物（枯草芽孢杆菌、酿酒酵母、乳酸片球菌）发酵结合复合酶制剂处理花生粕，可以综合改善其饲用品质。研究表明：处理后花生粕中AFB1的去除率为94.6%，非淀粉多糖含量由30%降低至10.5%，蛋白质含量由47.8%提高至61.5%，大分子蛋白明显降解为小分子蛋白，小肽含量由5.36% 提高至25.21%，必需氨基酸总量提高了19.67%，乳酸含量由0.7%提高至2.8%。经过生物技术法处理，花生粕的饲用品质得到了明显改善。 |
| 英文摘要: |
| Peanut meal has defects of aflatoxin B1(AFB1) easy to exceed standard, high content of non-starch polysaccharides(NSP), poor quality of protein, etc. Peanut meal was treated by microbial(Bacillus subtilis, Saccharomyces cerevisiae and Pediococcusacidilactici) fermentation combined with complex enzyme. The feeding quality of peanut meal was improved. The results showed that after treatment the removal rate of AFB1 in peanut meal was 94.6%, NSP content decreased from 30% to 10.5%, protein content increased from 47.8% to 61.5% and macromolecular protein obviously degraded into small molecule protein. The small peptide content increased from 5.36% to 25.21% and the total content of essential amino acid was improved by 19.67%. Additionally, the content of lactic acid increased from 0.7% to 2.8%. The quality of peanut meal was greatly improved by biotechnology treatment. |
