LIPOMEC: towards a better understanding of ruminant milk lipolysis through an integrative biology approach in milk and mammary gland
Résumé
Lipolysis is defined as fat-breakdown through the hydrolysis of triglycerides, the major component of milk fat. Short-chain fatty acids consequently released in milk are responsible for rancid flavor, unacceptable for consumers, in milk and dairy products. In addition, the presence of partial glycerides impairs milk functional properties such as foaming and creaming abilities. Thus, milk lipolysis represents an important criterion to assess milk quality. Spontaneous lipolysis results from a complex interplay between farming practices, animal physiology and animal genetics. However, changes in milk fat breakdown differ markedly between cow (Vanbergue et al., 2018) and goats (Chilliard et al., 2014), whereas ewe milk lipolysis is poorly understood. LIPOMEC, funded both by the French National Research Agency (ANR-19-CE21-0010) and dairy stakeholders (APIS-GENE), is the first large-scale integrative project to study the lipolytic system in the milk and mammary gland in the three dairy species.
