There are various established methods as pasteurization. Heretofore, only the kinetic figures of microbial inactivation were considered but not those of reaction impairing the chemical quality. For a gentler processing, knowledge of the kinetics of relevant chemical conversion reactions is necessary. 5-(Hydroxymethyl)-furfural (HMF) formation and the color change of juices are important attributes. The non-isothermal Rhim method was used to determine the activation energy and pre-exponential factor for HMF formation in different juices and an isothermal method for the reaction order. Values for the activation energy from 133 to 303 kJ/mol were obtained with a zeroth reaction order. A correlation between HMF and the color change could be found. Based on the kinetic figures, lines with equal effects for the chemical changes and for the lethal effect on microorganisms were calculated. Time-temperature settings for the gentlest treatment could be found."}],"type":"scientific_journal_article","status":"public","doi":"https://doi.org/10.1515/ijfe-2020-0324","article_type":"original","issue":"9","citation":{"mla":"Katsch, Linda, et al. “Kinetic Studies of 5-(Hydroxymethyl)-Furfural Formation and Change of the Absorption at 420 Nm in Fruit Juices for the Improvement of Pasteurization Plants .” International Journal of Food Engineering , vol. 17, no. 9, 2021, pp. 703–13, https://doi.org/10.1515/ijfe-2020-0324.","chicago":"Katsch, Linda, Frank-Jürgen Methner, and Jan Schneider. “Kinetic Studies of 5-(Hydroxymethyl)-Furfural Formation and Change of the Absorption at 420 Nm in Fruit Juices for the Improvement of Pasteurization Plants .” International Journal of Food Engineering 17, no. 9 (2021): 703–13. https://doi.org/10.1515/ijfe-2020-0324.","din1505-2-1":"Katsch, Linda ; Methner, Frank-Jürgen ; Schneider, Jan: Kinetic studies of 5-(Hydroxymethyl)-furfural formation and change of the absorption at 420 nm in fruit juices for the improvement of pasteurization plants .
