An Austrian physicist has invented what he claims to be the world's first fat-free crisp. The physicist, Peter Schwarzhans, has developed a special system which uses heated air to dry crisps instead of frying them in oil, reports Ananova.com.
The entrepreneur hopes his invention will earn him a healthy slice of the £1.5 billion (€1.68bn) worldwide crisp market, despite the fact that his crisps are not made out of potatoes at all but sunflowers.
He said: "I tried it at first using potatoes but while producing something that looked like crisps, the taste was disgusting.""But then I started using the tubers of a north American sunflower. The results were remarkable. What I'd produced was something that looked like crisps, tasted just like them and which lasts just as long. Because they are made in hot air they stay fresh for weeks and remain crispy," he added.
The process has now been patented and Mr Schwarzhans says several major manufacturers are vying to put it into production.
