长期保存牡蛎样品中脂溶性贝类毒素的检测方法
摘要：
本发明公开长期保存牡蛎样品中脂溶性贝类毒素的检测方法，该方法包括如下步骤：(1)待测样品预处理；(2)提取样品游离脂肪酸；(3)游离脂肪酸三氟化硼甲酯化后气相色谱检测；(4)结果校正。本发明采用校正的三氟化硼甲酯化方法对留存牡蛎样品中脂溶性贝类毒素进行校正性检测的方法，提供了一种可以通过检测留存贝类样品中贝类毒素含量来获得原产样品中毒素准确含量的方法。通过有效校正，使即时的检测值准确反应留存样品原始真实的贝类毒素含量，可获得准确的数据信息以支持回溯性研究。
摘要（英）：

The invention discloses a determination method of lipid soluble saxitoxin in a long-term-preserved oyster sample, and the method comprises the following steps: (1) sample pretreatment; (2) extracting of free fatty acids in the sample; (3) boron trifluoride methyl esterification of the free fatty acids, and gas chromatography detection; and (4) result correction. The determination method uses a corrected boron trifluoride methyl esterification method for corrected detection of the lipid soluble saxitoxin the preserved oyster sample, and a method for obtaining the accurate content of toxins in an original production sample by detection of the saxitoxin in the preserved oyster sample is provided. Through effective correction, a real-time detection value can accurately reflect the original content of the saxitoxin in the preserved oyster sample, accurate data information can be obtained, and the retrospective study can be supported.
