"Today, efficient preservation technology is not only applied in Beijing, but also radiates to 93 major cities across the country." Recently, Zhao Xiaoyan, director of the Agricultural Product Processing and Food Nutrition Research Institute of the Beijing Academy of Agriculture and Forestry, told reporters that this technology can extend the vegetable preservation period to 2-4 times its original value. "Our team has integrated various advanced technologies such as efficient pre cooling technology, packaging technology, and light preservation technology from vegetable production areas, ensuring the freshness of vegetables from the source." Zhao Xiaoyan said that the application of these technologies can not only effectively extend the freshness period of vegetables, but also maintain their nutritional components from being damaged, truly achieving the full process of freshness from the field to the hands of consumers. Specifically, efficient pre cooling technology in vegetable production areas can quickly reduce the temperature of vegetables after harvesting, effectively slowing down their respiration and metabolism rates, thereby extending their shelf life. Advanced packaging technologies, such as using modified atmosphere packaging and biodegradable packaging materials, can not only further extend the shelf life of vegetables, but also reduce environmental pollution. Light preservation technology can inhibit the growth of harmful microorganisms in vegetables and promote the synthesis of beneficial substances through specific wavelength light treatment. In addition, by combining the preservation technology of vegetable products with information technology, we have improved the quality control accuracy and intelligence level of the new e-commerce vegetable supply chain, improved storage and transportation efficiency, and ensured the quality of vegetables Zhao Xiaoyan said. Nowadays, this technology is widely promoted and applied in major vegetable production areas, e-commerce enterprises, industrial leading enterprises, specialized circulation enterprises, and farmer cooperatives, reducing vegetable loss, improving storage and transportation quality, enhancing circulation efficiency, and promoting the improvement of industry technology level. Zhao Xiaoyan is proud that the team's efforts have met the needs of consumers for diverse and high-quality fresh vegetables, while promoting the upgrading of the entire vegetable industry chain and providing strong support for increasing the income of vegetable farmers.
