Folates’ thermal degradation in spinach and green beans purees. The left part of the graph represents the thermal degradation of total folates expressed as folic acid in
mg/kg of fresh weight at 45 C (A), 65 C (B) and 85 C (C) in spinach under atmospheric oxygen conditions. The right part of the graph represents the thermal degradation of
total folates (mg/kg of fresh weight) at 45 C (D), 65 C (E) and 85 C (F) under atmospheric oxygen conditions in green beans. Empty lozenges correspond to data from batch 1
and empty squares represent data from batch 2.
