	Depending on temperature and pressure settings, HPP can achieve either pasteurization-equivalent log reduction or go further to achieve sterilization, which includes killing of endospores. Pasteurization-equivalent HPP can be done in chilled temperatures, while sterilization requires at least 90 °C (194 °F) under pressure. The pasteurization-equiavalent is generally referred to as simply HHP (along other synonyms listed above), while the heated sterilization method is called HPT, for high pressure temperature. Synonyms for HPT include pressure-assisted thermal sterilization (PATS), pressure-enhanced sterilization (PES), high pressure thermal sterilization (HPTS), and high pressure high temperature (HPHT).[7]		Depending on temperature and pressure settings, HPP can achieve either pasteurization-equivalent log reduction or go further to achieve sterilization, which includes killing of endospores.
