Zusammenfassung:To provide a retort sterilization method capable of sterilizing by selecting a uniform sterilization temperature by numerically expressing conditions for effectively performing sterilization without damaging quality of food products from a packaging form, size of a packaging container and etc., according to a kind of the food product.SOLUTION: In a retort sterilization method for individually packaged products, depending on the heat transfer property and packaging form of the contents to be packaged, from three variables of a target Fo value (unit: minutes), a product thickness H and a come-up time (CUT) for retort sterilization, a function for calculating a reference sterilization temperature that indicates a minimum CV value (unit: minutes) is created, and an executing sterilization temperature is set within a temperature range of the reference sterilization temperature ±5°C calculated from the function to perform the retort sterilization.SELECTED DRAWING: None 【課題】食品の種類に応じて、包装形態、包装容器の大きさなどから食品の品質が損なわれずに殺菌を効果的に行う条件が数式化され、画一的な殺菌温度を選定して殺菌を行うことが可能なレトルト殺菌方法を提供する。【解決手段】個装容器詰製品のレトルト殺菌方法において、 包装される内容物の熱伝達性及び包装形態に応じて、レトルト殺菌に際しての目標Fo値(単位:分)、製品厚みHおよびカムアップタイム(CUT)の3つの変数から極小CV値(単位:分)を示す基準殺菌温度を算出するための関数を作成し、該関数から算出された基準殺菌温度±5℃の温度範囲に実行殺菌温度を設定してレトルト殺菌を行うことを特徴とする。【選択図】 なし
