Sources of Food Contamination

Sources of Food Contamination

Contamination of food by microbial agents and natural toxins poses significant risks to public health. These hazards can be introduced at various points across the food supply chain, ranging from environmental sources to processing and storage stages. Understanding these contamination pathways is critical for developing strategies to ensure food safety.Seafood is particularly vulnerable to contamination through both environmental exposure and microbial colonization. Toxins from harmful algal...

Key Elements for Plant Nutrition

Key Elements for Plant Nutrition

Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the atmosphere, the...

Agricultural Science
Computer Science
Food Science

Background:

Food fraud is a significant global issue, impacting consumer trust and economic integrity.
Accurate origin verification of agricultural products like bananas is challenging but crucial for supply chain transparency.
Existing methods for origin detection may not be sufficient for proactive fraud prevention at the cultivation stage.

Purpose of the Study:

To develop and evaluate an Artificial Intelligence (AI)-based proof-of-concept for detecting the country of origin of Cavendish bananas (Musa spp.).
To explore the utility of citizen science-generated imagery in conjunction with deep learning for agricultural product authentication.
To establish a foundational AI pipeline for proactive food fraud detection at the cultivation level.

Main Methods:

Utilized a dataset of 6000 citizen science images of Cavendish bananas sourced from iNaturalist.
Employed Convolutional Neural Networks (CNNs), specifically leveraging transfer learning with pre-trained models like MobileNetV1.
Implemented data augmentation techniques to address class imbalance and enhance model robustness.

Main Results:

The CNN model, particularly MobileNetV1, showed promising performance in distinguishing banana origins across six countries.
Achieved an average accuracy of 0.86 with Monte Carlo Cross Validation and 0.77 with 5-Fold Cross Validation.
The final selected model demonstrated a validation accuracy of 0.79, indicating significant potential for origin detection.

Conclusions:

This study presents a foundational proof-of-concept for AI-driven origin detection in agricultural products at the cultivation stage.
The findings suggest a promising new avenue for proactive food fraud detection using accessible imagery and advanced computational models.
The developed AI pipeline offers a scalable framework that can be further expanded and independently validated for real-world applications.
