Abstract
The present paper deals with the modified mothod of vitamin E determination in milk, based on Emmerie-Engel's method. The method consists of the extraction of the fat-soluble substances in milk, the sulfuric acid hydrolysis of the extracts and the colorimetric determination. With this method, the recovery of α-tocopherol was 96.3 per cent and the experimental error was ±3.88 per cent. Vitamin E contents in cow's milk were 123 to 207μg per 100ml, and in human milk, were 297 to 1098μg per 100 ml.
