Current heating regimens for pasteurizing apple cider do not account for chlorine exposure in the wash water. The energy level applied did not affect any of the measured quality attributes.Įxposure of Escherichia coli O157:H7 to chlorine before heat treatment results in increased production of heat shock proteins. All treatments significantly changed the colour of apple juice and the sequence in which the technologies were applied affected colour significantly (P<0.05). When the technologies were applied individually the maximum reduction achieved was 2.7 and 4.9logCFU/mL (for TS (H) and PL (H) respectively), while most of the combined treatments achieved reductions in the vicinity of 6logCFU/mL, showing an additive effect for both technologies when acting in combination, regardless of the sequence applied. The effect of the resulting four energy levels and sequence (PL+TS and TS+PL) was studied. ![]() The juice was also processed by TS (24kHz, 100μm) at 40☌ for 2.9min (L) or 50☌ for 5min (H), corresponding to 14J/ml energy inputs, respectively. Two PL (360μs, 3Hz) treatments were selected and the juice exposed to energy dosages of 4.03J/cm2 (‘low’ (L)) and 5.1J/cm2 (‘high’ (H)) corresponding to 51.5 and 65.4J/mL, respectively. Selected quality attributes (pH, ☋rix, colour (L, a, b, ΔE), non-enzymatic browning (NEBI) and antioxidant activity (TEAC)) were also evaluated pre- and post-processing. It does not store any personal data.Pulsed light (PL) and Thermosonication (TS) were applied alone or in combination using a continuous system to study their effect on Escherichia coli inactivation in apple juice. ![]() The cookie is set by the GDPR Cookie Consent plugin and is used to store whether or not user has consented to the use of cookies.
