Vertical axis sterilizing time, liquid food filling rate sterilizing time becomes constant without depending on headspace gas volume in the graph showing the relationship of the head space gas and the amount of the sterilizing time of the horizontal axis represents each of the head space gas amount performing sterilization by sliding unconstrained pouch was sealed and filled in a flexible pouch contents.縦軸が殺菌時間、横軸がヘッドスペースガス量をそれぞれ表す殺菌時間とヘッドスペースガス量の関係を示すグラフにおいてヘッドスペースガス量に依存することなく殺菌時間が一定となる充填率で流動性食品内容物を可撓性パウチに充填し密封した後パウチを非拘束状態で摺動式殺菌を行う。
