Method and device for digitally detecting quality of edible vinegar

Abstract

The invention discloses a method and a device for digitally detecting the quality of edible vinegar. The device comprises a sample container which is placed on the upper surface of a conveying belt, can move forwards along with the conveying belt and contains an edible vinegar sample, a vinegar color and state information acquisition component, a vinegar aroma information acquisition component and a vinegar taste information acquisition component are sequentially disposed at suitable positions, the sample container moves forwards and passes through the suitable positions, the vinegar color and state information acquisition component, the vinegar aroma information acquisition component and the vinegar taste information acquisition component respectively acquire color and state information, aroma information and taste information, the three types of information are fused to form a data matrix, a principle component factor is extracted from the data matrix to be used as an input vector of a judging model by means of principle component analysis, a multi-variable progression model between the principle component factor and edible vinegar sample grades evaluated by professionals is built by an artificial neural network, and digital information of the flavor and the quality of the edible vinegar to be tested can be obtained according to the built model. The method and the device have the advantages that objective, accurate and quantitative representation of the flavor and the quality of the edible vinegar is guaranteed, and integrity and completeness of the representation of the flavor of the edible vinegar are ensured.
