摘要：

To provide a method for easily or accurately detecting or predicting the occurrence timing of goby during roasting of coffee beans.SOLUTION: The goby detecting method of coffee beans according to the present invention comprises a sound measuring step of measuring a sound generated from coffee beans being roasted over time and a sound measuring step of measuring a sound included in a range of 5 kHz or more and 80 kHz or less And a gauze detecting step of detecting a gobase of coffee beans based on the sound pressure of the frequency of the coffee beans. It is preferable to start the sound measurement process from 2 minutes after the start of roasting. It is preferable to further have an initial carbon monoxide amount measuring step of measuring the amount of carbon monoxide generated from coffee beans being roasted at least until two minutes after the start of roasting.(FIG.【課題】コーヒー豆の焙煎に際し、ハゼの発生時期を簡易且つ正確に検知又は予測する方法を提供する。【解決手段】本発明に係るコーヒー豆のハゼ検知方法は、焙煎中のコーヒー豆から発生する音を経時的に測定する音測定工程と、音のうち５ｋＨｚ以上８０ｋＨｚ以下の範囲に含まれる範囲の周波数の音圧に基づいて、コーヒー豆のハゼを検知するハゼ検知工程と、を有する。焙煎開始２分後から、音測定工程を開始することが好ましい。少なくとも焙煎開始２分後まで、焙煎中のコーヒー豆から発生する一酸化炭素量を測定する初期一酸化炭素量測定工程をさらに有することが好ましい。【選択図】図４
