A detection method for water-injected meat based on near-infrared spectroscopy

Abstract

The invention discloses a near infrared spectrum based water-injected meat detecting method, and belongs to the technical field of food detection. The detecting method comprises the following steps: acquiring infrared spectrum of a sample, obtaining a relative moisture content of the sample through measurement and calculation, then preprocessing the spectroscopic data, obtaining a target matrix, dividing the matrix into a calibration set and a prediction set, in accordance with samples in the two data sets, the corresponding spectroscopic data and the obtained relative moisture content through calculation, establishing a regression prediction model, evaluating the prediction accuracy of the model, repeating the steps for many times, at last determining the optimal preprocessing method and the best prediction model. The equipment for executing the detecting method is simple in structure; the detecting operation is simple and direct, and the detecting process is quick; the method is nondestructive, the detected sample is not required to be specially processed, and an operator is not required to understand specialized knowledge; the near infrared equipment and the assorted device are high in cost performance, suitable for being carried because of the small size, and suitable for popularization in the market; the method can be used for meat finished product markets and further for industrial production lines.

Description

technical field [0001] The invention belongs to the technical field of food detection, and in particular relates to a water-injected meat detection method based on near-infrared spectroscopy. Background technique [0002] The problem of water-injected meat in the Chinese market has a long history. For a long time, consumers have mostly selected meat based on experience, and there is no authoritative standard to judge and distinguish water-injected meat from normal meat. The water-injected meat disrupts the market order, and because a large amount of water is injected into the meat, consumers fall into the trap of weight fraud and suffer economic losses. In addition, the water injected into water-injected meat has not been metabolized by organs, which is fundamentally different from the inherent water in meat. The source of this water is unknown, and there are serious health risks, which pose a threat to the health of consumers. [0003] All in all, the problem of water-inje...
