Abstract

The invention discloses a device and a method for detecting varieties of beef sauce seasoning liquid. The method comprises the following steps: firstly, dividing n types of beef sauce seasoning liquids into m beef sauce seasoning liquid specimens with equal mass; secondly, detecting each specimen of each sample by a sensor array sequentially to obtain n threshold values of Thr1, Thr2, ..., Thrn which are related to the varieties of the beef sauce seasoning liquids; thirdly, detecting a beef sauce seasoning liquid W to be detected so as to obtain the signal-to-noise ratio spectrum characteristic value noise width sigma of the beef sauce seasoning liquid W; fourthly, calculating a dynamic classification parameter delta of the beef sauce seasoning liquid W by using a nonlinear self-calibration dynamic classification model; and finally, determining that the variety of the beef sauce seasoning liquid W is variety j by a computer. The device and the method have the characteristics of capability of quickly and accurately differentiating the varieties of the beef sauce seasoning liquids.

Description

[0001] The invention relates to the technical field of food flavor detection, in particular to a variety detection device and detection method of beef sauce seasoning liquid capable of quickly and accurately distinguishing types of beef sauce seasoning liquid. Background technique [0002] At present, artificial sensory evaluation method is generally used for food flavor, 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 suitable for on-site detection. [0003] Chinese patent authorization announcement number: CN101769889A, a...
