Gas analysis for food safety is a critical technology to ensure food quality and safety, monitoring the risk of spoilage during storage and transportation by accurately detecting gas components inside packaging (such as oxygen, carbon dioxide, and volatile organic compounds). The device employs a high-precision sensor array combined with intelligent algorithms to analyze the proportion of headspace gas components in real-time, achieving ppm-level data accuracy. The casing is made of explosion-proof stainless steel with corrosion-resistant seals, adapting to various food packaging environments. Its advantage lies in fast detection speed and precise results, enabling early warning of microbial contamination or oxidative spoilage. Widely used in shelf-life assessment of meat, fruits, vegetables, baked goods, and dairy products, it helps enterprises optimize packaging processes, extend product shelf life, and reduce food waste.
