省產糙薏仁膨發產品的沖泡性質研究 1 2 須文宏 黃俊儒 1. 國立宜蘭技術學院食品科學系副教授 2. 國立宜蘭技術學院食品科學系講師 摘 要 本實驗利用單軸擠壓機及膨發鎗對糙薏仁進行膨發實驗。單軸擠壓機部份顯示，須配合50%比例之玉 米粉混合方能有良好之膨發產品，但擠壓產品的沖泡性均不理想。以膨發鎗進行糙薏仁膨發，發現膨發壓 力與產品形狀完整與否有密切關連，壓力較小時，膨發產品形狀不完整，膨發壓力越大，形狀則愈趨完 整，實驗結果亦顯示，膨發槍製品磨粉後之沖泡性較佳。 關鍵詞：擠壓、膨發槍、糙薏仁、即食食品、沖泡性 Research in Pouring Capability of Puffing Crude Adlay Products 1 2 Wen-Hung Hsu , Jin-Ru Huang 1. Associate Professor of Department of Food Science, National Ilan Institute of Technology 2. Instructor of Department of Food Science, National Ilan Institute of Technology Abstract Crude adley half-products were made by single-screw extruder and puffing gun in this study. In the single- screw extruder experiments, there’s impossible to extrude with pure crude adley. As mixing with corn powder (50%), desirable extrusion half-products could be produced. The extrudates are not suitable as the basis of pouring products. For the puffing gun procedure, the shape of puffing crude adley was greatly influenced by puffing pressure. The higher puffing pressure was, the better shape was. The pouring capability of puffing products was better..
