ICE CREAM THAT MELTS SLOW

 

Every  body    loves  ice cream  but  there  is  a  problem ,it  melts   so  fastly   that  some times  it  drips   off  the  hands .Now    a  new  ingredient   developed   by  scientist   in  Scotland   could  mean   that  ice cream  lovers   can  enjoy  their  teats  longer  before   they  melt.
A  naturally occurring protein can be used to create ice cream which stays frozen for longer in hot weather.
The scientists estimate that the slow-melting product could become available in three to five years.
The development could also allow products to be made with lower levels of saturated fat and fewer calories.
 The development could also allow products to be made with lower levels of saturated fat and fewer calories.
Teams at the Universities of Edinburgh and Dundee have discovered that the protein, known as BsIA, works by binding together the air, fat and water in ice cream.
It is also said to prevent gritty ice crystals from forming - ensuring a fine, smooth texture.
 Prof  Cait  Mac Phee, of the University of Edinburgh's school of physics and astronomy, who led the project, said: "It's not completely non-melting because you do want your ice cream to be cold. It will melt eventually but hopefully by keeping it stable for longer it will stop the drips."

The team developed a method of producing the protein - which occurs naturally in some foods as friendly bacteria.
Prof MacPhee said it works by keeping oil and water mixed together, stops air from escaping and coats the ice crystals in ice cream which stops them from melting so quickly. 
 According  to Prof  MacPhee , it  is a natural protein already in the food chain. It's already used to ferment some foods so its a natural product rather than being a 'Frankenstein' food.
"By using this protein we're replacing some of the fat molecules that are currently used to stabilize these oil and water mixtures so it can reduce the fat content, but it shouldn't taste any different.
 She said it also had the prospect of reducing the sugar content and could be used in other foods such as chocolate mousse and mayonnaise to help reduce the calories.
The researchers believe using the ingredient could benefit manufacturers too as it can be processed without impacting on performance and can be produced from sustainable raw materials.
