求生物工程专业英语翻译
Application in maltose syrup production
The hydrolysis of dextrins was carried out with -amylase from barley. Two pullulanase dosages were used: 1.42 and 0.36 U/g-dextrins.When dextrins were only hydrolyzed by -amylase, the reducing sugars concentration at 22.5 h of saccharification time was 172 g/l. If the pullulanase is used before the saccharification step by -amylase,
higher reducing sugars levels can be obtained.With 1.42 U/g-dextrins, at 22.5 h of saccharification time, the concentration of reducing sugars was increased of 14% and with 0.36 U/g-dextrins the increase was of 6.5% 。
These results are dued to the mode of action of the -amylase. Indeed the -amylase can neither hydrolyze the -1,6 glucosidic linkages nor bypass these linkages. This leads to an accumulation of high DP material referred to as -limit dextrins, residues
containing -1,6 glucosidic branch points.

麦芽糖浆生产中的应用。糊精水解的进行伴随大麦α-淀粉酶。普鲁兰酶用量分别用两种：1.42和0.36单位/克糊精。当糊精只被α-淀粉酶水解。还原糖22.5小时糖化时间浓度为172克/升。如果普鲁兰酶使用在被淀粉酶糖化前，更高的还原糖量可以被获取。用1.42单位/克，糊精的糖化时间在22.5小时，还原糖含量增加了14％，用0.36单位/克糊精则增长6.5％。
这些结果是预期到了淀粉酶的作用方式。事实上，α-淀粉酶水解既不能-1,6糖苷的联系，也没有绕过这些联系。这导致了物质积累的高聚合度被称为限制糊精，残留物含有-1,6糖苷分支点。
应该是α淀粉酶，有些翻译不通。
