IT has been found that coffee seeds contain small amounts of certain vitamins, among which niacin prevails in higher proportion.

In order to determine the possible effect on niacin content of varying environmental conditions under which coffee is grown, as well as of the different methods of processing, two sets of specially prepared samples were analysed.
