Acquisition device for near-infrared transmitted spectrum of vinegar and method for identifying vinegar origin

The invention discloses an acquisition device for a near-infrared transmitted spectrum of vinegar and a method for identifying a vinegar origin. The near-infrared transmitted spectrum of a vinegar sample is acquired by a detector in the acquisition device, and the acquired spectrum signals are transmitted to a microprocessor; and in the process of building a model, a qualitative judgment model is built by a mode recognition method, a correcting model which reaches the prediction accuracy is selected and introduced into the microprocessor, and the near infrared spectrum information of a predicating sample is mixed into the selected correcting model for calculation, and the origin information of the vinegar sample is obtained. The acquisition device provided by the invention is simple in structure, low in cost and convenient to take, and is capable of acquiring the near-infrared transmitted spectrum of the vinegar; and the method for identifying the vinegar origin provided by the invention identifies and researches the vinegar origin by a near infrared spectrum technology and the mode recognition method, thereby having the advantages of high recognition rate, fast analysis speed and greening analysis and the like.
