A healthier version of the classic sausage roll could eventually become a reality as Scottish researchers develop a plant-based alternative to traditional pastry fats.Scientists at Heriot-Watt University in Edinburgh, Scotland, recently reached a new milestone toward making a healthier sausage roll without sacrificing flaky pastry by moving their experiment from the lab to their food industry partner's kitchen, the university announced in a news release."By taking innovative food science out of the lab into the kitchen and testing it with everyday consumers, it has the potential to make the nation's favorite snacks healthier and make a genuine difference to our health and wellbeing," said Stephen Euston, a professor working on the pastry research.CLICK HERE TO DOWNLOAD THE FOX NEWS APPSausage rolls are a British favorite that consist of seasoned sausage meat baked in puff pastry."Around 10-15 million sausage rolls are sold a week in the UK, and the bestselling version contains 11 to 12.4 grams of saturated fat," Euston said."That's more than 60% of the recommended daily limit for adults."Sausage rolls are popular in the United Kingdom, but they typically contain high amounts of saturated fat.
