this could be the reason why samples did not show statistical dif- ferences in the studied parameters sugar content in control snacks, are more likely to suffer browning reactions or caramelization reactions as reported by Sacchetti et al.
(2004) who observed this behavior in chestnut flour extruded products, where they observed that a higher sugar content in the mixtures, darkest products are obtained, attributed to the Maillard and caramelization reactions carried out during ex- trusion process.
