The present invention provides a manufacturing method for grain puffed food. After crushing and adjusting humidity of a grain material, a gelatinized semi-finished product is formed by a processing method of extruding and puffing. The gelatinized semi-finished product is then baked to reduce water. After the gelatinized semi-finished product is solidified by cooling, the solidified semi-finished product is placed into a warming mixer to be mixed with food grade salt and stirred at a high temperature for secondary maturation. After stirring, the solidified semi-finished product is sieved to remove the food grade salt and bad components thereof. The remained semi-finished product after sieving is cooled to become the final product of grain puffed food. The present invention can improve taste of traditional grain food and avoid starch aging phenomenon. Therefore, the grain puffed food not only can be eaten directly, but also can be processed with other miscellaneous food to become diversified cereal nutritious food.一種五穀類膨化食物之製造方法,首先將一五穀原料經過粉碎與調濕之後,再以擠壓膨化的加工方式成形出一糊化半成品,接著烘烤糊化半成品降低水份,等到冷卻形成一固化半成品之後再放到加溫拌攪機內混合食用級鹽巴一起進行高溫拌攪而二次熟化,在拌攪完成之後進行過篩處理,藉以去除食用級鹽巴及不良品,其餘順利完成過篩的部分在冷卻之後即為五穀類膨化食物的成品,本發明可以改善傳統五穀類食物的口感與避免澱粉老化現象,因此除了可以直接食用之外,也可以拿來跟其他雜糧類食物一起加工成多樣化的穀物營養食物。
