1960年,我们测定了常用动物性食品中胆固醇的含量。测定方法:主要采用氏方法略加改进。要点即以胆固醇氯仿提取液在醋酸酐硫酸混合液作用下呈现之兰绿色与标准管比色(根据 Lierman—Burchakd 氏反应发展而来)。样品的选取与处理:自4—6只畜体的不同部位取少量动物组织,混匀,取0.5—1克或5—10克作为一个样本。每种食物取2—8个样本。牛奶则取10毫升为一个样本。 In 1960, we measured the cholesterol content of commonly used animal foods. Determination: The main method used to improve slightly. The key point is the blue-green and standard tube colorimetric (according to Lierman-Burchakd’s reaction) of the chloroform chloroform extract in acetic anhydride and sulfuric acid mixture. Sample Selection and Handling: Take a small amount of animal tissue from different parts of 4-6 carcasses, mix, take 0.5-1 grams or 5-10 grams as a sample. Take 2-8 samples for each type of food. Take 10 ml of milk as a sample.
