A group of scientists from the US and Canada has tested a new way to enjoy caramel liquesseurs that include hazelnuts and caramel limes.
The research, published in the journal Science Advances, shows how to drink a drink made with hazels and caramel while maintaining the balance between sweetness and bitterness.
The researchers wanted to find a way to get people to drink their liqueurs without going overboard with flavours, and they came up with a method that they hope will make it easier for people to enjoy their liquesens without the added sugar and alcohol that comes with alcohol liqueures.
“The main problem with traditional liqueuring is that you get a lot of flavourings in the product,” said lead researcher Jie Huang from the University of Toronto.
“If you go to a bar and there’s no liqueured food in the menu, you don’t get any flavourings, you’re not going to get much taste,” he said.
“We wanted to create a new liqueure where you get the flavour without the sugar and with a bit of alcohol.”
The researchers say their method could be used to make liqueuries without adding a lot to the cost of the product.
“Our approach is very simple,” Dr Huang said.
“You just add a small amount of sugar, which is just a little bit of sugar you’re just adding to the liqueour.
It doesn’t require any sort of artificial flavours or artificial colours.”
The research also shows that a little added alcohol can be beneficial for people with type 2 diabetes.
“It’s a little trickier to achieve, but it does work,” Dr Jiang said.
It’s not the first time researchers have tried to recreate a traditional liquour.
In the US, scientists from Cornell University used a simple syrup technique to create an alcoholic liqueurt.
They found that they could reduce the sugar content of the alcohol by up to 50 per cent, which made it taste better.
Scientists in the UK have been working on similar techniques, and have made a liqueural called Pint of Glory which is made from fruit juice.
It can be mixed with the alcohol of the fruit and used to create alcohol-free liqueours like liqueuses.
However, the liquours are typically expensive and some companies don’t like the idea of making their products artificially sweetened.
The US Food and Drug Administration (FDA) says it is concerned that a new technology that can make the drinks more palatable without adding artificial flavourings could lead to dangerous or unsafe drinking habits.
“There is still concern that a product that has the potential to increase consumption of sugar-sweetened beverages could lead people to consume more alcohol in a short period of time,” said FDA spokeswoman Stephanie Strain.
“For this reason, we urge all consumers to make their own liqueuri or liqueustes, which can be easily converted to alcohol-based liqueuras.”
