Embodiment

[0044] Infrared spectroscopy is a qualitative and quantitative analysis technique for specific components of objects based on the principle that specific structures such as atoms and molecules inside objects have different absorption characteristics for electromagnetic waves. It has the advantages of fast, non-destructive, and simple, and is widely used in agricultural product testing. Currently, it is widely used in tea, honey, glucose wine, rice, olive oil, and meat products. The invention mainly combines the infrared spectrum technology with the method of building a model, so that the adulteration of livestock meat, such as pork, beef, mutton, etc., can be detected and identified.

[0045] A method for identifying adulteration of livestock meat applied to origin traceability, such as figure 1 shown, including the following steps:

[0046] S1: Prepare multiple sample sets of different meats, each sample set includes multiple samples;

[0047] S2: separately collect the ori...

Abstract

The invention discloses a meat adulteration identification method and apparatus applied to origin traceability. The method comprises the following steps: S1: respectively preparing a plurality of different meat sample sets, wherein each sample set comprises a plurality of detection samples; S2: respectively collecting an original spectrum of each detection sample in S1; S3: calculating a mahalanobis distance of each detection sample and a mahalanobis distance threshold value of each meat, obtaining a singular point sample according to the mahalanobis distance of each detection sample and the mahalanobis distance threshold value of the corresponding meat, removing the singular point sample from the sample set of each meat, and obtaining corresponding residual sample sets; S4: preprocessing the original spectrum of all detection samples in the plurality of residual sample sets; and S5: randomly classifying all detection samples in the plurality of residual sample sets into a correction set and a detection set, and establishing an identification model for the detection set by virtue of a modeling method. By adopting the method and apparatus, the adulteration identification of different meats can be realized.

Description

technical field [0001] The invention relates to the field of meat identification, in particular to a method and device for identifying adulterated meat. Background technique [0002] In real life, there are many meat adulteration incidents in the market, making the safety of meat products at the forefront, attracting controversy and attention. For example, from 2014 to 2015, an investigation was conducted on the adulteration of beef and mutton and its products in Guangdong Province: Among the 50 samples tested, 10 adulterated meat products were detected, with a total adulteration rate of 20.0%. It can be seen the severity of adulteration in the domestic meat market. Incidents of food fraud, adulteration, and shoddy food not only seriously endanger the health and interests of consumers, but also affect the development of related enterprises and the public's trust in domestic food safety. For example, pork is used as beef and mutton. [0003] Therefore, it is imminent to qu...
