The loaf bread has a somewhat different composition from that of rusks, so both of them behave differently when left out in the open. The biscuits only contain 2 to 3% water and tend to absorb it from the outside because the recipe also includes sugar that binds to water. On the contrary, normal bread dries up and ends up getting stale because, established by law, it has up to 40% water but no sugar. Its absence and internal humidity cause it to tend to lose water and end up dry and rancid.
