EFFECT OF FREEZING ON DIFFUSION OF ASCORBIC ACID DURING WATER HEATING OF POTATO TISSUE.
Author(s) : GARROTE R. L., SILVA E. R., BERTONE R. A.
Summary
THE EFFECT OF FREEZING ON ASCORBIC ACID LOSSES DURING WATER BLANCHING OF POTATO CYLINDERS (DIAMETER = 10 MM ; LENGTH = 80 MM) AT 323, 338 AND 353 K (50, 65 AND 80 DEG C) WAS STUDIED AT DIFFERENT PERIODS OF TIME. THE APPARENT DIFFUSIVITIES OF ASCORBIC ACID DURING WATER BLANCHING WERE DETERMINED AT 323, 338 AND 353 K. THE ACTIVATION ENERGY OF THE DIFFUSION PROCESS WAS 12.58 KILOJOULE/MOL. ASCORBIC ACID APPARENT DIFFUSION COEFFICIENTS IN POTATO WITH PREFREEZING TREATMENT ARE HIGHER THAN THOSE FOR FRESHTISSUE. FREEZING PRODUCES STRUCTURE CHANGES.
