The invention discloses a steamed bread quality detection method. The method comprises putting a steamed bread sample to be detected into a determination end of a whiteness meter, determining and recording a whiteness value, taking a steamed bread sample to be detected, detecting and recording a specific volume, cutting a steamed bread sample to be detected to obtain small cubic pieces with the size of 5*5*5cm, detecting texture parameters of the small cubic pieces through a texture analyzer, taking a steamed bread sample to be detected and analyzing volatile substance components in the steamed bread through a solid phase extraction-gas chromatography / mass spectrography combined method. Through determination of the specific volume, the steamed bread size and shape are measured. Through determination of a whiteness value, a steamed bread color is obtained. Through determination of texture parameters, steamed bread hardness, taste and elasticity are measured. Through analysis of steamed bread volatile substance components, a steamed bread smell is measured. The detection method is simple and easy, has a high standardization degree and realizes objective steamed bread quality evaluation.
