Ultra-weak photon emission: a nondestructive detection tool for food quality and safety assessment
A new aspect covering interactions between cells and their surroundings via electromagnetic waves was introduced by applying ultra-weak photon emission (UPE). The UPE originates from the relaxation of electronically excited species resulting from oxidative metabolic processes and oxidative stress associated with reactive oxygen species (ROS). The ROS plays a critical role in the quality of foods, and their determination is of extreme importance. The ROS and the intensity of the UPE have significantly correlated. The UPE can be effectively monitored by specific instruments such as photomultiplier tube and charged-coupled devices. The current review is devoted to providing an overview of the quality of food products by the aid of UPE via evaluating the correlations between UPE and food quality indices. In this regard, the UPE can be utilized in food quality as a real-time, noninvasive, and nondestructive technique without complex instruments. However, the implementation of the UPE method for evaluation of food quality needs further investigations.
期刊介绍:
''Quality Assurance and Safety of Crops & Foods'' is an international peer-reviewed journal publishing research and review papers associated with the quality and safety of food and food sources including cereals, grains, oilseeds, fruits, root crops and animal sources. It targets both primary materials and their conversion to human foods. There is a strong focus on the development and application of new analytical tools and their potential for quality assessment, assurance, control and safety. The scope includes issues of risk assessment, traceability, authenticity, food security and socio-economic impacts. Manuscripts presenting novel data and information that are likely to significantly contribute to scientific knowledge in areas of food quality and safety will be considered.
''Quality Assurance and Safety of Crops & Foods'' provides a forum for all those working in the specialist field of food quality and safety to report on the progress and outcomes of their research.
