澱粉糖工業用液體糖化酶
介紹
The product is produced by mixing a carefully optimized proportion of glucoamylase and pullulanase coming from submerged fermentation of Aspergillus niger and Bacillus subtilis, respectively. The combination of glucoamylase with ingredientary pullulanase makes saccharification more efficient by avoiding limit dextrin and by-product formation, and therefore saving processing cost while producing more glucose.

單位的定義
1單位糖化酶等於在40℃、pH 4.6下1h內水解可溶性澱粉得到1mg葡萄糖的酵素量。
1單位普魯蘭酶等於在pH 5.8、50℃下1分鐘內從普魯蘭多醣中釋放出1μmol還原糖（以葡萄糖計算）所需的酵素量。
機制
普魯蘭酶是異澱粉酶的一種，可以選擇性水解普魯蘭多醣、澱粉和寡糖中的α-1,6-糖苷鍵，從而使支鏈澱粉的完全水解成為可能。當與葡糖澱粉酶一起使用時，它會透過降解 α-1,6-糖苷鍵加速糖化並增加葡萄糖產量。
反應參數
| 參數 | 範圍 |
| 活動溫度 | 30℃-65℃ |
| 最佳溫度 | 58℃-64℃ |
| 活性pH值 | 3.5-6.0 |

Application Rate
The recommended application rate is 0.35-0.6公斤 糖化溫度60-63℃、pH 4.3-4.5時每噸乾澱粉酶製劑用量。起始劑量為 0.45公斤 per ton of dry starch is recommended under most conditions. However, the optimal application rate depends on the specific process parameters and should be determined by testing different application rates.
包裹
包裹： 1公斤/袋.
貯存
密封保存於乾燥陰涼處，避免陽光直射。輕微的沉澱是可以遵循的，因為它不會影響產品的性能。
保存期限
12個月 置於乾燥陰涼處。
安全
Enzyme preparations are proteins that may induce sensitization and cause allergic type symptoms in susceptible individuals. Prolonged contact may cause minor irritation for skin, eyes, or nasal mucosa. Any direct direct skin contact should be avoided. If irritation or allergic response for skin or eyes develops, please consult a doctor.
