Inactivation of Lipase in Grains: Processing Methods, Kinetics, and Storage Stability.
Lipase activity in grains is a critical factor limiting the shelf-life of whole-grain flours and brans. Inside intact kernels, lipase and its substrates are separated by structural barriers. Once lipase is in contact with the substrate (triacylglycerols, TAGs) after milling, it hydrolyzes TAGs into free fatty acids (FF...
