The rate of salt release in-mouth from salted potato crisps was evaluated. It was hypothesised that

a slow steady release of sodium would occur on chewing and hydration; to test this a crisp was chewed

and held in the oral cavity without swallowing for 60 s. Sodium release was measured over the entire

holding period, after 20–30 s a peak in salivary sodium levels was recorded. A similar trend was

observed with sensory perceived saltiness by trained panellists. The results suggest that a significant

proportion of the crisp’s salt flavouring is released in a pulse-type mechanism which would not be

encountered when the crisp is exposed to normal eating patterns and would result in the consumption

of a large proportion of unperceived sodium.
