Ice cream and freezing point depression

Click For Summary
SUMMARY

The discussion centers on the impact of room temperature and surroundings on the ice cream-making process using zip loc bags and a salt/ice mixture. It concludes that while the environment does have some effect, the closed system created by the zip loc bags minimizes this influence, allowing ice cream to be made even in a warm room. However, extreme conditions, such as a sauna, may hinder the process.

PREREQUISITES
  • Understanding of freezing point depression
  • Familiarity with the principles of heat transfer
  • Knowledge of closed systems in thermodynamics
  • Experience with basic kitchen equipment, specifically zip loc bags
NEXT STEPS
  • Research the principles of freezing point depression in culinary applications
  • Explore thermodynamic concepts related to closed systems
  • Investigate alternative methods for making ice cream, such as using an ice cream maker
  • Learn about the effects of different salt types on freezing point depression
USEFUL FOR

Culinary enthusiasts, food scientists, educators teaching thermodynamics, and anyone interested in the science of ice cream making.

When you make ice cream using a couple of zip loc bags and a salt/ice mixture do the room and surroundings have any effect? Can you be in a warm room and still make the ice cream? Thanks.

Well the room and the surroundings always have some effect on the results of an experiment, but with the ziploc bags you are trying to achieve a closed system, in which no matter or heat can be transferred to the surroundings. The influence of the surroundings, in this case, is negligible. So, yes you can still make ice cream in a warm room, but it might be a little difficult in a sauna :smile: .
