Lipase-catalyzed modification of milk fat: A promising way to alter flavor notes of goat milk products

The rancid and tart off-flavor of goat milk limits the popularization of its associated products. In this study, a two-step enzymatic catalysis method was proposed to generate new aromatic notes that could alter the negative flavor perception of goat milk products. The goat milk fat was first hydrolyzed to prepare fatty acids (FFAs) as substrates, and then esterification was carried out for the synthesis of esters with pleasant notes. In the...
