Abstract
Ascorbic acid in a bentonite suspension was used as a model of a thermally preserved food system. The bentonite was packed in high barrier plastic trays and in metal cans and ascorbic acid retention was evaluated. Storage temperatures of 15, 25, 35 and 45 °C were used. After sterilization and during storage the plastic trays showed an overall better ascorbic acid retention. However, the rate constants for ascorbic acid degradation were higher in the trays than in the cans. The period for which the trays showed better ascorbic acid retention than the cans was shorter at higher storage temperatures. Ascorbic acid degradation rate constants in the trays showed lower temperature dependence (lower energy of activation) than in the cans and gave a good correlation with oxygen permeability of the trays at 25 °C.
