Conclusion
In the present study, the formation of 5-HMF, F, 3H2P and FA
generated during conventional or ohmic heating processing were
investigated in chunky fruit desserts. Results revealed that accumulation
of 5-HMF and F was in relation with the severity of
heating (conventional vs. ohmic) applied to such fruit products
during processing. Conversely, the production of 3H2P and FA
mainly depended on AA oxidative degradation reactions rather
than thermal degradations, as they were similarly formed in both
heating treatments. The potential presence of DHA in fruit desserts
could help to confirm the role of the oxidative pathway in losses of
AA, provided this compound was stable enough to be determined
in the processed apple-derived desserts.
