In addition to vitamins, calcium, other minerals, and
proteins obtained from milk products, modern research
has suggested healthful properties of fermentationderived
peptides and butyric acid found in some
dairy products (1, 2, 3). Moreover, organic acids are
relevant in dairy products for nutritional reasons and
because they contribute to the flavor and aroma. They
are the major products of carbohydrate catabolism of
lactic acid bacteria and nonstarter bacteria associated
with milk (4).
