浙江发生的“泰国越南毒龙眼事件”被媒体报道后,引起了国内外广泛关注。二氧化硫作为一种非常有效的果蔬食品保鲜剂,在生产上已被广泛使用。近年来,国内外不少研究者开始研究二氧化硫结合冷藏保鲜龙眼的技术,泰国龙眼采后二氧化硫处理技术已面向生产,而我国还处于试验阶段。华南农业大学和广东省农科院果树所共同合作,在国内较早研究了龙眼采后二氧化硫保鲜作用及其残留量问题。他们经过长 Occurred in Zhejiang, “Thailand, Vietnam, poisoned longan incident,” was reported by the media, aroused widespread concern at home and abroad. As a very effective fruit and vegetable food preservative, sulfur dioxide has been widely used in production. In recent years, many researchers at home and abroad have started to study the technology of combining sulfur dioxide and refrigerating and preserving longan. The post-harvest sulfur dioxide treatment technology of longan in Thailand has been oriented to the production and our country is still in the experimental stage. South China Agricultural University and Guangdong Provincial Academy of Agricultural Sciences fruit trees work together to study earlier in the domestic longan post-harvest sulfur dioxide preservation and its residual capacity issues. They are long
