In the latter case, the high cold price created by the straight contact with the incredibly cold cryogenic fluid provides increase to development of extremely small ice crystals, which have a soft and smooth appearance. Pre-aeration Gelato contains up to 60% of air (by quantity), which is generally added within the ice cream SSHE.

Pre-aeration of the ice lotion mix in this means can have an impact on structure characteristics of the end product such as suppleness as well as stiffness10. The small air cells created have been found to have a substantial impact on the perception of creaminess and also smoothness and enhance the shape retention of the ended up ice cream throughout distribution.

Improved air cell circulation, melt-down time and storage space stability have been claimed. While procedure developments have been sluggish to arrive in the gelato company, there is now solid proof that such growths are important to the evolution of the market.
