Salt is NOT added to the ice cream, it is added to the ice in manual ice cream freezers to reduce the melting temperature if the ice, making it colder than 32F speeding up the freezing of the ice cream in the container inside the ice cream freezer.A compressor ice cream freezer does not need ice and salt and is much less trouble to use.
Ice is added to decrease the melting point of ice cream.
The Salt lowers the temperature I made home made ice cream but never used salt for it.
Salt is put in the ice around the actual ice cream so that the ice doesn't melt.Actually the salt is added to the ice in the ice cream maker to make the ice melt FASTER, thus getting colder and speeding up the freezing of the ice cream.Use of a compressor ice cream machine makes use of the ice & salt mixture unnecessary.
The salt is not "in" the ice cream, rather is added to the ice that surrounds the ice maker bucket to aid in chilling.
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. ;)
because it keeps the ice colder for longer
Salt is added to ice because it makes the ice melt faster, and melting ice absorbs more heat (from the ice cream batter) than non-melting ice does. The faster the ice absorbs heat, the faster your ice cream gets done.
Salt has the effect of making the ice colder. Therefore, the ice cream becomes colder too. Salt is added to ice to lower the temperature of the ice/water mixture. Without the salt, the temperature would not fall below 0 degrees Celsius, which is needed to make ice cream. The freezing point of salt water is below that temperature and thus allows the cream to partially freeze, a necessary part of making ice cream.
salt lowers the freezing point of water
Added salt lower the frezing point of water; this is important for the use as an deicing material or for ice cream preparation.
there is salt in homeade ice cream because if u use ice, the salt has to melt the ice to make the ice cream. :-)
