英国农业生物技术公司Tropic开发的基因编辑香蕉近日获得英国环境、食品和农村事务部的营销许可1。这种香蕉采用CRISPR-Cas9技术减少褐变酶的生成，使其在剥皮后能够保持黄色外观一至两天1。根据Tropic公司的测算，这类非褐变香蕉有望减少食品浪费和供应链二氧化碳排放超过25%1，并可支持香蕉出口市场年度碳排放减少超过900万吨1。
英国政府研究表明，每天有140万个可食用香蕉被丢弃1。约30%的消费者因香蕉皮肤上的轻微瘀伤或黑点而将其丢弃1。Tropic公司已在包括日本、巴西和菲律宾等10个国家获得监管批准，该产品已在拉丁美洲进行种植1。
Britain's Department for Environment, Food and Rural Affairs has granted marketing authorization for gene-edited bananas developed by agricultural biotechnology company Tropic 1. The bananas, created using CRISPR-Cas9 technology, have been modified to reduce the production of browning enzymes, allowing them to maintain their yellow appearance for one to two days after peeling 1.
Tropic claims the non-browning bananas could reduce food waste and supply chain carbon dioxide emissions by more than 25 percent 1. The company estimates the innovation could support annual CO2 emission reductions exceeding 9 million tonnes across the banana export market 1. Government research indicates that 1.4 million edible bananas are discarded daily in Britain, with 30 percent of consumers throwing away bananas due to minor bruising or black spots on the skin 1.
The gene-edited crop has already secured regulatory approval in 10 countries, including Japan, Brazil, and the Philippines, and is currently being cultivated in Latin America 1. The approval follows the implementation of UK precision breeding regulations for plants in November, which apply solely to England 1.
