Abstract
The aim of this study was to determine the levels of folic acid in Brown Swiss and Simmental cows’ milk by the competitive ELISA method. Brown Swiss and Simmental cows’ milk samples were collected from two dairies between February and August 2017 (20 samples from Brown Swiss and 22 samples from Simmental). The average level of vitamin B9 in Brown Swiss milk was approximately 3.27 ± 1.23 μg/100 g, while for Simmental it was around 2.99 ± 0.88 μg/100 g. In the milk mixture, the mean folic acid level was 3.13 ± 1.07 μg/100 g. There was no statistical difference between breeds in terms of folic acid levels in cow's milk. It was concluded that milk is not a sufficient source to meet the daily folic acid needs of adults in Turkey. Keywords : Dairy cattle breeds, folic acid, raw milk
Highlights
Folic acid, a natural form of folate, is a water-soluble vitamin in the B group of vitamins (Anonymous, 1998; Shils et al, 2005; Bailey & Gregory, 2006)
Folic acid taken with food is absorbed via its passage along the intestinal mucosa after being hydrolyzed in monoglutamate form in the intestines
It is estimated that the total folic acid content in human metabolism is between 10 and 30 mg
Summary
A natural form of folate, is a water-soluble vitamin in the B group of vitamins (Anonymous, 1998; Shils et al, 2005; Bailey & Gregory, 2006). It is estimated that the total folic acid content in human metabolism is between 10 and 30 mg. Half of this amount is stored in the liver and the other half is found in blood and other tissues (Shils et al, 2005; Bailey & Gregory, 2006)
