Impact of Milk Preacidification with CO2 on the Aging and Proteolysis of Cheddar Cheese*
|
ABSTRACT
To determine the influence of milk preacidification with CO2 on Cheddar cheese aging and proteolysis, cheese was manufactured from milk with and without added CO2. The experiment was replicated 3 times. Carbon dioxide (approximately 1600 ppm) was added to the cold milk, resulting in a milk pH of 5.9 at 31°C in the cheese vat. The starter and coagulant usage rates were equal for the control and CO2 treatment cheeses. The calcium content of the CO2 treatment cheese was lower, b...
