The effect of different pH levels (3.4 to 7.0) on 5-formyltetrahydrofolic acid (5-CHOH₄PteGlu) stability during thermal (80-110°C) and high pressure thermal (100-800 MPa/65-70°C) processing was studied. The results showed that (i) the degradation of 5-CHOH₄PteGlu during treatments (in the presence of ascorbic acid) was due to not only oxidation but also a conversion to 5,10-methenyltetrahydrofolic acid (5,10-CH=H₄PteGlu); and (ii) multiple response analysis was successfully applied to describe the kinetics of 5-CHOH₄PteGlu degradation during thermal and/or high pressure processing.
