The applicability of anhydrous milkfat fractions in edible films and coatings was determined through moisture barrier, penetrometer, and stress-relaxation testing. Industrial milkfat fractions were compared along with tripalmitin:anhydrous milkfat blends which simulated milkfat fractions having different melting points. The water vapor permeability (WVP) was determined gravimetrically using a modified ASTM...
The activity of chymosin, plasmin, and Lactococcus
lactis enzymes (cell envelope proteinase, intracellular
peptidases, and glycolytic enzymes) were determined
after 5-min exposures to pressures up to 800 MPa.
Plasmin was unaffected by any pressure treatment.
Chymosin activity was unaffected up to 400 MPa and
decreased at 500 to 800 MPa....
