Effects of preservation at temperatures between -1 and -4 deg C on the shelf life of pastries.

Conséquences d'une conservation entre -1 et -4 deg C sur la durée de vie des pâtisseries.

Author(s) : BERGIS H., BEAUFORT A., RUDELLE S.

Summary

The microbiological quality of pastries stored at temperatures within a range of 0 deg C and their freezing point, then at temperatures above 0 deg C simulating sales presentation, was investigated. Two types of pastry can be distinguished: those with a freezing point under -4 deg C and those with a freezing point within the -1 et -4 deg C range. The microbiological quality of pastries stored at -1 deg C varies according to the type of pastry. Preservation at this temperature does not enable the shelf life to be extended significantly. However, where pastries were stored at -4 deg C, the microbiological quality remained stable throughout the 8-week storage period. Assessment of the organoleptic properties of these pastries showed that these properties remained stable following a 2-week storage period.
