Boob Scoop: Some mothers may notice their expressed milk will have a “soapy” appearance and a taste/smell that becomes sour-smelling rather quickly after being stored. This results from an excess of the enzyme lipase in their milk and only affects a small percentage of mothers. Lipase is responsible for breaking down the fat in breastmilk. If there is an excess of Lipase, then the fat gets broken down too quickly after being expressed, and results in the soapy appearance and sour smell described above. The milk is not harmful and most babies are not bothered by the mild change. However, the longer the milk sits in room temperature, the more apparent the taste/smell becomes to the baby, which of course, may result in more aversion.
