科技日报北京1月11日电 (记者瞿剑)记者11日从中国农科院获悉,最新农业行业标准《饲料中37种霉菌毒素的测定液相色谱串联质谱法》发布,并将于4月1日起实施。由该院农业质量标准与检测技术研究所饲料质量安全检测与评价创新团队制定的该项标准,是全球首个饲料中霉菌毒素高通量检测标准;其成功研发并发布,扩大了我国饲料及畜产品中霉菌毒素监测范围,提升了风险发现能力。

团队首席、中国农科院质标所研究员苏晓鸥介绍,饲料及农产品中霉菌毒素污染是一个全球性问题,给农业生产和食品安全带来严重挑战。霉菌毒素由于种类多、结构差异大以及样品基质复杂等原因,多类毒素高通量检测一直是产业瓶颈。目前,检测标准和文献报道方法多为单一或单类霉菌毒素检测。

团队着眼于饲料中多种霉菌毒素同时污染的现实问题,从基础理论入手,历时5年攻关,在大量实验数据基础上,提出多重机制杂质吸附原理,研制出适合饲料基质中5类37种霉菌毒素同时净化的杂质吸附型净化柱,解决了样品基质干扰严重、兼顾不同种类危害物结构及理化性质差异巨大等两个关键技术难题,样品净化时间从40分钟以上缩短至两分钟以内。基于多重机制杂质吸附净化柱制定出农业行业标准《饲料中37种霉菌毒素的测定液相色谱串联质谱法》,是目前世界上饲料中霉菌毒素“一次提取、一次净化、一次上机”同步测定数量最多的标准方法。应用该方法参加2016年度欧盟、2018和2019年度亚太地区饲料原料霉菌毒素同步检测国际实验室能力验证,结果全部满意。

该项研究授权国家发明专利1项,在国内外刊物上发表研究论文3篇;形成的多重机制杂质吸附净化技术已向有关生物技术企业转让,实现了产、学、研的深度融合。
