Pistachio nuts could provide a caffeine-free and healthy alternative to the popular hot coffee, say researchers.
The search for a caffeine-free coffee has often proven less than fruitful, with versions of the drink which lack not just caffeine’s kick, but flavour. Now, a team at University of York claims to have found a possible solution in a type of pistachio nut.
The researchers claim that carefully roasted, the fruit of the Pistacia terebinthus tree, which is much smaller than normal pistachios, could offer all the flavour of coffee, with none of the kick - as well as being significantly cheaper.
According to them, pistacia has the same chemical “signature” as real, caffeinated, coffee - meaning it can be made to have the same taste and aroma.
The researchers found that when they roasted the Pistacia terebinthus nuts for 20 minutes at 200 degrees they started to show a volatile chemical profile similar to roasted coffee beans, ‘The Daily Telegraph’ reported.
