The comparison of the model predictions with literature data showed a similar trend in overestimating degradation at some processing steps (Table 3). For instance the mean predicted vitamin C loss at blanching was estimated at 58% while it did not exceed 28% in previous publications. Vitamin C losses during storage reported in previous works were very low, contrarily to the present work with both observations on the industrial and pilot processing lines, and with model predictions. Overall the prediction of vitamin C degradation in the green bean process was much higher than previously reported (88% vs. 45%). However Vitamin C concentrations recorded in the French Food Composition tables are comprised between 0 and 8 mg. 100 g−1 for drained canned green beans, with an average concentration given at 3.5 mg 100 g−1 (CIQUAL, 2013) and these values are in agreement with those predicted by the model, i.e. 4.4 mg 100 g−1 [0, 10.6] after sterilization or 2.3 mg 100 g−1 [0, 5.6] after a prolonged storage.
