VEGEMITE flavoured chips are about to hit supermarket shelves in the latest evolution of Australia's famous spread.

After nine months of secret taste testing, flavourists from Smiths Chips and Kraft have created a crinkle-cut chip that tastes just like the national spread - only crunchy.

The companies believe the odd pairing, which creates a buttery-tasting chip with a tangy Vegemite aftertaste, could be a winner when it goes on sale next month.

The idea for a Vegemite-tasting chip was hatched at Coles headquarters in Glen Iris, where product developers brought Kraft and PepsiCo executives together to create the fast food match.

Smiths had already come up with wacky flavours such as Heinz Big Red and pizza.

They also produced a limited-edition gravy flavour after a national campaign by 2DayFM radio stars Andy Lee and Hamish Blake to find the people's chip.

A national marketing campaign for the Vegemite flavour was ready to roll out later this month, but details of the new chip leaked to The Sunday Telegraph last week.

Vegemite is one of Australia's most popular foods, with more than 22 million jars sold each year.

The new Vegemite crinkle cut chip will be sold for 12 weeks from October 6, but only at Coles stores.

Despite Vegemite's salty reputation new Vegemite flavoured chips have one of the lowest sodium counts on the market

with an average of 583mg of sodium per 100g - almost half the sodium content of Salt and Vinegar.
