Characterization of Changes in Composition and Physicochemical Properties of Casein Micelles from Raw Milk to Buttermilk
<p>It is well-documented that buttermilk has poor coagulation properties due to changes that occur to the casein micelles during the butter-making process. These modifications are generally attributed to the pasteurization of the cream upon which interactions between the proteins are promoted. It …

Screening Listeria monocytogenes from bulk tank milk and in-line milk filter samples for the routine monitoring of the dairy farms
Increased consumption of raw milk has been observed among the urban population in Europe along with an increasing consumer interest in foods that are less processed and locally produced. Raw milk and raw milk products have been associated with listeriosis caused by Listeria monocytogenes. These new …

Inhibition of Psychrotrophic Bacterial Growth in Refrigerated Milk by Addition of Carbon Dioxide
<p>The advent of on-farm refrigerated storage for raw milk in the late 1940's and its subsequent adoption by North American dairyman 'during the next 20 years essentially eliminated spoilage of milk by lactic acid bacteria. However, refrigeration does not prevent growth of all microorganisms …
