中文摘要:
      目的 了解我国食品检测实验室的大豆粉中转基因成分的检测能力。方法 国家认可委组织实施了大豆粉中转基因成分的检测能力验证工作。15个省、市、自治区的37 家实验室参加了本次能力验证。本研究介绍了本次能力验证的实施过程, 包括方案设计、样品制备、一致性稳定性试验、结果统计等, 并对能力验证结果进行了分析。结果 实验室检测结果满意率为94.60%, 样品检测结果一致率为98.90%。结论 参加能力验证的绝大多数实验室可以准确检测大豆粉中转基因成分, 具备了分子生物学检测转基因食品的能力。
英文摘要:
      Objective To understand the capability of Chinese food inspection laboratories for detecting genetically modified component in soybeans. Methods China National Accreditation service for Conformity Assessment(CNAS) organized the proficiency test (PT) for detecting genetically modified component in soybeans. 37 laboratories from 15 provinces/cities/municipals took part in the PT. In this paper, the implementation process of the PT was described, including project design, sample preparation, homogeneity and stability test, results statistic and analysis, etc. Results There were 94.60% laboratories and 98.90% samples showing satisfactory results. Conclusion Most laboratories taking part in the PT had good competence in analyzing genetically modified component in food with molecular biology.
