For a gentle dimensioning of a pasteurization plant the knowledge of the kinetic figures is important. Activation energy, reaction order and pre-exponential factor of the L-ascorbic acid degradation in a model solution, apple, orange and black currant juice were determined. Lines of equal effects, which indicate different time-temperature combinations for the degradation, could be derived and compared with the lethal effect on microorganisms. The activation energies were located in the area of 25 to 44 kJ/mol for all samples except of orange juice (74 kJ/mol) in the range of 40-90 ?C with a zeroth reaction order. Based on these values, the lines of equal effects showed a lesser degradation at higher temperatures and shorter holding times even in the typical setting range of pasteurization plants.","lang":"eng"}],"article_type":"original","_id":"5418","type":"scientific_journal_article","issue":"7/8","year":"2020","publication_identifier":{"issn":["0723-1520"],"eissn":["1613-2041"]},"date_created":"2021-04-08T05:51:47Z","doi":"https://doi.org/10.23763/BrSc20-13katsch","quality_controlled":"1","place":"Nürnberg","language":[{"iso":"eng"}],"date_updated":"2024-07-19T12:41:52Z","department":[{"_id":"DEP4023"},{"_id":"DEP4018"},{"_id":"DEP1308"}],"publisher":"Fachverlag Hans Carl GmbH"}
