AI Technical Summary
Existing volatile organic compound (VOC)-based detection systems are mainly used to determine whether grains and foods are contaminated or to accurately detect the amount of fungi, but there is a lack of methods for accurately detecting aflatoxin B1 (AFB1) through VOCs.
A compact intelligent gas sensing and detection system for AFB1 was designed by using a dual-branch convolutional neural network (DB-CNN) to analyze the temporal dynamics and spatial characteristics of fungal metabolic VOCs data. The system extracts gas fingerprints through parallel convolutional channels, enabling high-precision quantitative analysis of AFB1.
It enables accurate differentiation between corn, peanuts, wheat and other grains infected with Aspergillus flavus and high-precision quantitative analysis of AFB1. It supports wireless transmission and is suitable for dynamic real-time monitoring of fungal contamination in the food supply chain, providing early warning and quality control.
