Hyperspectral imaging, also known as chemical or spectral imaging, it is an emerging technology that combines traditional imaging and spectroscopy to obtain and analyze a large amount of spectral and spatial information from real scenes in the form of three-dimensional images. Compared with traditional imaging and spectroscopy, image processing and analysis are the core of hyperspectral imaging technology. In recent years, with the increasing demand for food quality and safety, hyperspectral imaging technology has been widely used in the safety inspection and quality control of various food production.

Principles of Hyperspectral Imaging Technology

Under the action of electromagnetic radiation sources in different wavelength ranges, each food has different ways of reflecting, scattering or absorbing energy due to its different chemical composition and physical structure, so each food has typical spectral characteristics. Among more and more food contaminants, food-borne microorganisms can cause chemical and structural changes of food in a short period of time. These changes can be detected based on the intensity of scattering or absorption of incident radiation by the food during the analysis process, and the presence of contaminants and their spatial distribution in the food sample can be determined.

Hyperspectral imaging technology is a non-destructive analysis technology, and has the advantages of accuracy, reliability, and speed. It is used to detect biological contaminants at different stages of food production, such as pathogenic microorganisms and spoilage microorganisms. CD BioSciences is a biotechnology company, we can use hyperspectral imaging technology to provide you with a series of food microbiological testing services to ensure the quality and safety of food. If you have any needs, please feel free to contact us.
