In good quality ice cream, milk fat. In cheap ice creams, carrageenan or guar gum or some other kind of sludge.
The reason why salt melts ice cream is the same as why it reduces the freezing lvl of water. It simply reacts with the ice seeing as the ice then gets a lower freezing point, the ice cream melts.
You need to have the salt in the ice around the chamber to ensure that the ice will stay as frozen as possible when freezing the ice cream. ;)
It is lower.
Salt acts as an antifreeze, reducing the melting/freezing point of the ice. This makes the salt & ice freezing mixture much colder than that of ordinary ice, causing the ice cream to freeze faster and with smaller crystals. An ice cream with smaller crystals feels smoother and creamier in the mouth.I use a compressor ice cream maker, which requires no salt & ice mixture as it has a built in electric powered freezer.
Rock salt is used because it causes the ice in the bucket to melt, but at the same time to be cold enough to freeze the ice cream inside of the canister. I am of course talking about the hand churned ice cream. If you didn't use salt, you would not be able to turn the canister to churn the ice cream mixture into a freezable substance.
Ice cream does become quite hard when held at the proper freezing temperature.
salt and ice are the freezing mixtures of ice.
Hard ice cream is...hard icecream!!!!

Yes. Ice-cream can burn your tongue if the ice-cream is really, really freezing cold.
by freezing it
A metal bowl keeps ice cream frozen the longest.
Normally, the ice cream out from machine (ice cream batch freezer) is about -6 degrees to -8 degrees. The best temperature for hard ice cream / gelato is about -18 degrees. Use one unit blast freezer for fast freezing ice cream. It can let the ice cream fast reach to target temperature to prevent crystallization. And the final step is storage ice cream in the display freezer, about -16 to -20 degrees. MEHEN FOOD MACHINE
Salt inhibits freezing (it makes foods have a higher freezing point), which helps the ice cream to remain soft enough to eat straight from the fridge.
To lower freezing point, making the ice cream mix in the container colder than freezing temperature so it freezes faster. Its much easier to make ice cream with a compressor freezer than a salt & ice freezer.
salt lowers the freezing point of water
Freezing is a physical process.
