Description

Technical Field

[0002] In the past few decades, food safety and quality have always been one of the focuses of people's attention. With the intensification of globalization and the increasing complexity of the food supply chain, ensuring the safety, quality and authenticity of food has become increasingly important. Traditional food testing methods often require complex laboratory operations and time-consuming sample processing processes, which limits their applicability in real-time monitoring and large-scale applications. Therefore, spectral-based food quality testing devices have emerged. This device uses optical principles and spectral analysis technology to quickly and accurately evaluate the quality, composition and safety of food without tedious sample preparation and laboratory testing. By analyzing the interaction between food samples and light, this device can detect the chemical composition, color, freshness, contaminants and authenticity of food, providing an important reference for food production and consumption.
