Abstract: To provide a processed grain product enabling manufacturing of a softened processed grain product for individuals who are elderly or who have difficulty in chewing or swallowing that maintains a post-threshing or post-polishing shape. The processed grain product according to the present invention is a processed grain product wherein the post-threshing or post-polishing shape is maintained, wherein a portion of the starch that is included in the processed grain product gelatinized, and that includes an externally derived degrading enzyme in a state that has enzymatic activity, and wherein the water content is less than 15%.

Abstract: In a state where food ingredients, degradative enzymes, and liquid seasonings are housed and sealed in a hard vessel, it has become possible to develop food products packaged in the hard vessel for normal temperature distribution or chilled distribution by a method of carrying out all of the steps inside the hard vessel, which method comprises carrying out an enzyme impregnation step and an enzymatic reaction step by heating and carrying out an enzyme deactivation step and sterilization step by continuous heating; or by a method of carrying out, after introducing the degradative enzyme into the food ingredient, some steps of enzymatic reaction step, enzyme deactivation step, and sterilization step inside the hard vessel.
