Pre-aeration of the gelato mix in in this manner can have a result on structure qualities of the end product such as suppleness and also stiffness10. The tiny air cells formed have been located to have a substantial effect on the understanding of creaminess and smoothness and enhance the shape retention of the finished gelato during distribution.

Boosted air cell distribution, melt-down time and also storage space security have actually been claimed. While process advancements have actually been slow-moving to show up in the gelato business, there is now firm proof that such growths are critical to the evolution of the sector.
