Food Cold Chain Logistics Traceability and Vegetable Nutrition Measurement Based on the Internet of Things
Lutein and zeaxanthin are both oxygen-containing carotenoids, and their sources mainly depend on the dietary intake of vegetables and fruits. Lutein and zeaxanthin have the antioxidant function of filtering blue light, quenching singlet oxygen, capturing reactive oxygen free radicals, and preventing their damage to biofilms. In recent years, China's food cold chain market has developed rapidly, with an annual growth rate of more than 8%. The development prospect of food cold chain logistics has caused widespread concern in the industry. Food safety, freshness and pollution-free requirements have been raised. In order to ensure the safety, real-time and reliability of food quality, food cold chain logistics came into being. This article uses RFID technology that enables items to speak, and WSN technology, which is relatively mature today, and wireless communication technologies such as GPRS / GPS, which are combined with computer networks to achieve information in production, transportation, storage and distribution. Quick sharing, collaborative operation and quick response, so as to more effectively realize the cold chain logistics tracking and tracing in the transportation process.
