Abstract
Sulfur dioxide (SO2) and its derivatives (SO2-3 and HSO-3) are ubiquitous in the environment and our daily life, closely related to human life activities. As an important additive, SO2 serves functions including bleaching, sterilization, anti-corrosion, color protection, antioxidant, and others during the processing and storage of food and pharmaceuticals. Additionally, SO2 can regulate the antioxidant enzyme system in human cells, increasing resistance against oxidative stress damage. However, excessive SO2 in the human body can strongly stimulate the digestive tract, causing nausea, vomiting, and abdominal pain, and may trigger allergic reactions including asthma and headaches. Furthermore, long-term intake can damage digestive and respiratory health. Therefore, developing rapid detection technology for the timely monitoring of SO2 content in food, pharmaceuticals, and living organisms is one of the means to ensure food safety and physical health. This paper summarizes the construction and recognition detection mechanism of SO2 probes based on fluorescence technology, and introduces the rapid detection application progress of SO2 in food, pharmaceuticals, and biological systems, and summarizes the advantages and limitations of the current probes.
