Leveraging RegNet and CBAM for precise detection of honey adulteration using thermal image analysis
Honey adulteration is a significant challenge with health and economic consequences. This research introduces a novel AI-driven approach using thermal imaging to classify honey adulteration levels. Traditional methods are slow and costly. We developed an adaptable AI model, integrating RegNet and CBAM, that achieves high accuracy (100% for pure and 1% adulteration, 98% for 3%, 97% for 5%) across various honey types, offering rapid and versatile detection. This innovative method enhances quality control and consumer confidence in natural bee products.
Executive Impact: Driving Precision and Efficiency
Our advanced AI solution for honey adulteration detection offers unparalleled precision, rapidly identifying adulterated products with high confidence. This not only safeguards consumer health and trust but also significantly reduces the operational costs and time associated with traditional, labor-intensive quality control methods. By integrating thermal imaging with a scalable, attention-enhanced deep learning model, enterprises can deploy a robust, versatile system that adapts to diverse honey varieties and adulteration levels, ensuring the integrity of their supply chain and market reputation.

Core Technologies
The system's backbone, RegNet, ensures scalable and precise feature extraction, handling complex thermal imaging data with high efficiency. The integration of CBAM further enhances this by applying dual-attention mechanisms (channel and spatial) to focus on the most informative temperature-related attributes and locations within each image, crucial for detecting subtle adulteration indicators.
Robust Performance Across Adulteration Levels
The model demonstrates strong performance, particularly for pure honey and highly adulterated samples. While mid-range adulteration levels present a greater classification challenge, the overall accuracy and precision highlight its reliability for quality control.

While some spectroscopy-based methods show higher accuracy, our thermal imaging approach offers a cost-effective and pragmatic solution with a strong balance of precision and recall, suitable for real-world applications without requiring specialized laboratory equipment.
Enhanced Interpretability with Grad-CAM++
To ensure transparency and trust in AI decisions, we utilized Grad-CAM++ visualizations. These heatmaps highlight the specific areas in thermal images that most influenced the model's classification, demonstrating how the AI discerns purity from contamination.
Case Study: Visualizing Adulteration Detection
Grad-CAM heatmaps reveal how the CBAM-enhanced RegNet model identifies honey adulteration. For pure honey, attention is uniform, indicating consistent thermal distribution. With low adulteration (e.g., 1%), the model shows dispersed attention, sensitive to minor thermal variations. As adulteration increases (e.g., 20%), the heatmaps show concentrated focus on specific regions, corresponding to significant temperature changes induced by glucose addition. This visual evidence validates the model's ability to identify contamination via distinct thermal fluctuations, offering a clear and interpretable framework for quality control in the food industry.
Acknowledged Limitations & Future Work
While robust, our model has certain limitations that guide future research and development directions.
Current Constraint: Melissopalynological Analysis
A significant limitation is the absence of melissopalynological analysis, the benchmark for floral source verification. Due to insufficient specialist experience and equipment, this method was impractical. We sourced honey from accredited cooperatives to ensure authenticity, but acknowledge that quantitative validation via melissopalynology would further strengthen provenance claims. Future studies will incorporate this testing for wider applicability.
Future Opportunities: Expanding Scope
Expanding the model's applicability to other honey varieties and bee-derived goods (e.g., royal jelly) is a key future direction. Evaluating its effectiveness in real-world, complex processing contexts and enhancing its ability to identify supplementary types of adulteration will further increase its value for the apiculture sector, making it an even more comprehensive quality control solution.
