在大多数热带国家，以碳水化合物为基础的农产品产量很大。广泛利用当地淀粉作物将带来各种经济和生态优势。当地的淀粉作物可以成为农村工业发展的催化剂，并最终开拓新市场。将使用较低剂量的冷淀粉水解酶制剂Stargen™ 002从典型的印度尼西亚淀粉（可食用美人蕉、竹芋、西米和甘薯）的潜在葡萄糖产率与玉米和马铃薯的潜在葡萄糖产率进行比较。当原料西米和甘薯淀粉的质量分数分别为40%（w/v）时，水解24 h后，葡萄糖当量产率分别达到88.4 g/L和86.3 g/L，而玉米淀粉为89.6 g/L。而竹芋和食用美人蕉的含量要低得多（分别为53.3 g/L和39.7 g/L）。这项研究表明，西米和甘薯淀粉可能提供有趣的替代玉米淀粉在冷水解转化淀粉为葡萄糖的过程。
In most tropical countries, carbohydrate-based agricultural products occur in large quantities. Wider utilization of local starch crops will offer various economic and ecological advantages. Local starch crops can be a catalyst for rural industrial development and eventually open up new markets. The potential glucose yield from the typical Indonesian starches (edible canna, arrowroot, sago, and sweet potato) using lower dosage of cold-starch hydrolyzing enzyme preparation Stargen™ 002 was compared with that of corn and potato. The glucose equivalent yield reached 88.4 g/L and 86.3 g/L after 24 h of hydrolysis when 40% (w/v) raw sago and sweet potato starches were used, respectively, as compared to corn starch (89.6 g/L). While arrowroot and edible canna gave much lower amounts (53.3 g/L and 39.7 g/L, respectively). This study demonstrates that sago and sweet potato starches may provide interesting alternatives to corn starch in a cold hydrolysis conversion process of starch into glucose.
