The US FDA was enabled to certify a PATS process of low acid foods in 2009. HPP is mainly used in a commercial environment as an effective postlethality technology for prepacked meat products. The majority of the HPP commercial meat products belong to RTE food category. In the United States, Hormel Foods is using HPP mainly for the elimination of L. monocytogenes, since the United States Department of Agriculture (USDA) regulatory authority maintains a policy of zero tolerance. Pressure levels applied for the pasteurization of meats and meat products, range in an area of 400–600 MPa with short processing times of 3–7 min at ambient temperature.
In reality, heat transfer between the sample and the pressure-transmitting fluid or the pressure vessel during the come-up time and hold time will likely influence the measured sample temperature. 2, significant differences in the compression heating behavior were observed in foods with high oil/fat content such as vegetable oil, cheese, and mayonnaise, and foods with high water content such as milk. Foods with a high water content such as milk experienced a temperature increase with pressure change similar to that of water (the polar component), in the range of 3°C per 100 MPa.
