EFFECT OF THE FREEZING RATE ON THE SORPTION ISOTHERMS AND RECONSTITUTION PARAMETERS OF FREEZE-DRIED BEEF.

Author(s) : TSVETKOV T. D.

Summary

FREEZING AT RATES OF 117 TO 160 K/MIN PROVIDES MATERIALS WITH A SPECIFIC SURFACE AREA WHICH INCREASES WITH THE FREEZING RATE. THERE IS NO AGREEMENT BETWEEN THE MEASUREMENTS OF SPECIFIC SURFACE AREAS MADE WITH WATER AND NITROGEN. THE WATER OF THE MONOMOLECULAR LAYER WAS DETERMINED AS A FUNCTION OF THE FREEZING RATE. REHYDRATION DEPENDS MARKEDLY ON THE FREEZING RATE. THE AUTHORS DEVELOPED A MATHEMATICAL EXPRESSION FOR THE ADSORPTION CURVES FOR WATER AND NITROGEN AND REHYDRATION CURVES.
