Zusammenfassung:To provide roast nut in which POV in storage is increased and quality deterioration is suppressed and shelf life is improved.SOLUTION: The production method (1) of fat-containing nut comprises a step for immersing roast nuts in melted fat, a step for reducing pressure of fat in which the roast nuts are immersed, and a step for increasing pressure of the fat in which the roast nuts are immersed. The production method of fat-containing nut described in (1) is configured so that, (2) absolute pressure for reducing pressure of the fat in which the roast nuts are immersed, is in a range from air pressure to 0.005 MPa. The production method of fat-containing nut described in (1) or (2) is configured so that (3) absolute pressure for increasing pressure of the fat in which the roast nuts are immersed, is in a range from air pressure to 0.5 MPa.SELECTED DRAWING: None 【課題】従来より保存中のPOV上昇および品質劣化を抑制し保存性が向上したローストナッツを得ることを目的とする。【解決手段】(1)融解した油脂にローストナッツを浸漬する工程と、ローストナッツが浸漬した油脂を減圧する工程と、ローストナッツが浸漬した油脂を昇圧する工程を有する、油脂含有ナッツの製造方法。(2)ローストナッツが浸漬した油脂を減圧する絶対圧が、大気圧〜0.005MPaであることを特徴とする、(1)に記載の油脂含有ナッツの製造方法。(3)ローストナッツが浸漬した油脂を昇圧する絶対圧が、大気圧〜0.5MPaである事を特徴とする、(1)または(2)に記載の油脂含有ナッツの製造方法。【選択図】なし
