but breakage of the membrane has not been reported.
On the other hand, a study of goat milk found that lipoprotein lipase
was somewhat resistant to pressurisation (Buffa, Guamis,
Pavia, & Trujillo, 2001); however, similar studies have not been
done in human milk, which contains, not only lipoprotein lipase,
but also bile salt-stimulated lipase. Therefore, we consider that
this point warrants further research. In addition, because free
fatty acids are known to be more susceptible to oxidation than
are fatty acids contained in triglycerides, the analysis of the free
fatty acids profile of human milk, before and after each treatment,
would give us valuable information, not only on the quality of the
processed product but also on its shelf life.
