Abstract

The presence of cholesterol in cleaned up fish tissue extracts has been established by gas-liquid chromatography and confirmed by mass spectrometry. It was found both in extracts cleaned up by gel permeation chromatography and in those extracts prepared by the AOAC method for nonfatty foods. It is not normally observed in routine residue analyses because selective gas chromatographic detectors such as electron capture are commonly used.

摘要

通过气液色谱法已确定了净化后的鱼组织提取物中胆固醇的存在,并通过质谱法进行了确认。在通过凝胶渗透色谱法净化的提取物以及采用AOAC法针对非脂肪食品制备的提取物中均发现了胆固醇。在常规残留分析中通常不会观察到胆固醇,因为通常使用诸如电子捕获等选择性气相色谱检测器。
