Abstract

The invention discloses a device and a method for detecting quality of a beef sauce seasoning liquid. The method comprises the following steps: detecting each specimen of qualified beef sauce seasoning liquids by a sensor array to obtain m signal-to-noise ratio spectrum characteristic value noise widths, and defining the average value of the signal-to-noise ratio spectrum characteristic value noise widths as a threshold value Thr; obtaining the signal-to-noise ratio spectrum characteristic value noise width sigma of a beef sauce seasoning liquid sample A; calculating a dynamic classification parameter delta of the beef sauce seasoning liquid sample A by using a nonlinear self-calibration dynamic classification model; and judging whether the beef sauce seasoning liquid sample A is qualified or unqualified by a computer. The device and the method have the characteristics of capabilities of detecting the quality of the beef sauce seasoning liquid accurately and providing reliable data support for a manufacturer to manufacture beef sauce with stable quality.

Description

technical field [0001] The invention relates to the technical field of food quality detection, in particular to a quality detection device and a detection method for beef sauce seasoning liquid that can accurately detect the quality of beef sauce seasoning liquid and provide reliable data support for manufacturers to produce beef paste with stable quality. Background technique [0002] At present, artificial sensory evaluation methods are generally used for food quality, but human sensory organs are easily disturbed by the environment, individual differences of judges and subjective factors, thus reducing the accuracy of evaluation results. And artificial sensory methods are not suitable for evaluating toxic substances. Although instrumental analysis methods represented by chromatography can qualitatively and quantitatively analyze food odor components, this method generally has shortcomings such as time-consuming, high cost, expensive equipment, and toxicity, and is not sui...
