[Nonesterified fatty acids and the titrable acidity of breast milk. Consequences for collection conditions in milk bans].
The study of breast-milk samples, fresh or after storage, shows that the titrable acidity (expressed in degrees Dornic) is directly correlated with their nonesterified fatty acid concentration. Those fresh samples which contain a high activity of lipoprotein lipase can develop in situ lipolysis. The resulting elevated titrable acidity may lead to consider these samples as unsuitable for infant nutrition. These results suggest that collection and storage of breast-milk have to be reassessed in order to avoid in situ lipolysis.
