Area of Science:

Food Science
Computer Vision
Artificial Intelligence

Background:

Meat adulteration poses significant risks to consumers and market integrity.
Current authentication methods often require specialized equipment, limiting accessibility.
The prevalence of fake meat products, such as duck-based "lamb" or "beef" slices, is a growing concern.

Purpose of the Study:

To develop a customer-friendly, non-destructive method for detecting meat adulteration.
To enable rapid authentication of meat slices using readily available technology.
To address the market impact of fraudulent meat products.

Main Methods:

A convolutional neural network (CNN) architecture, MTx-Net, was designed for efficient image analysis.
The MTx-Net incorporates techniques like residual connections, depth-wise convolution, dropout, and batch normalization.
A large dataset of 77,956 meat images was collected for training and testing.

Main Results:

The developed method achieves high accuracy in authenticating meat slices.
99.38% accuracy was recorded for lamb slice authentication.
98.20% accuracy was achieved for beef slice authentication.

Conclusions:

A novel, mobile phone-based system can effectively detect meat adulteration.
The MTx-Net model provides a rapid and non-destructive solution for consumers.
This approach enhances food safety and consumer trust in the meat market.
