摘要
早籼稻谷及其糙米体外消化试验结果揭示 ,添加非淀粉多糖 (NSP)复合酶制剂使早籼稻谷干物质、粗蛋白、粗脂肪和粗纤维的体外消化率分别提高了 16 .2 9%、9.10 %、10 .11%和 92 .0 7% ,使糙米中上述营养物质的体外消化率分别提高了 2 7.4 6 %、2 6 .4 1%、2 0 .6 7%和 7.16 % ,达极显著水平 ;使早籼稻谷和糙米中各种氨基酸体外消化率显著提高 ,幅度分别为 9.4 8%～ 4 0 .79%和 7.93%～ 4 1.74 %。添加NSP复合酶制剂使早籼稻谷和糙米体外消化过滤液中葡萄糖含量分别增加了 6 9.39%和 88.5 1% ,总氨基酸含量分别增加了 11.5 2 %和 11.83%。
The digestive experiment in vitro showed that, non- starch polysaccharide (NSP) enzymes significantly increased the digestibility of dry matter, crude protein, ether extract and crude fiber in early rice grain by 16.29%, 9.10%, 10.11% and 92.07% and in brown rice by 27.46%, 26.41%, 20.67% and 7.16%, respectively. The digestibility of amino acid in early rice grain and in brown rice were increased by 9.48-40.79% and 7.93-41.74%, respectively. Moreover, NSP enzymes could enhance glucose and total amino acid content by 69.39% and 88.51% and by 11.52% and 11.83% in digestive filtration solution of rice grain and brown rice, respectively.
