Pasteurizing eggs in their shells is achieved through a technique that uses precise time and temperature zones within water baths. [ 14 ] [ 15 ] Pasteurizing eggs in their shells can also be achieved through a process that involves treatment with ozone and reactive oxygen species under high and low pressures, followed by replacement with an ...
Because apple juice is acidic, typically with a pH of 3.4, it can be pasteurized for less time or at lower temperatures than many other juices. For this purpose, the U.S. Food and Drug Administration recommends the following thermal processing times and temperatures in order to achieve a five- log reduction of Cryptosporidium parvum as this ...
