SUMMARY

The discussion centers on the phenomenon where hot milk, when placed in a cool solution, tastes like water after some time. Participants clarify that osmosis is not the cause since a glass jar is impermeable. Instead, the heating process may cause milkfat to separate from the liquid, altering the taste perception. This suggests that temperature and fat content play significant roles in flavor changes.

PREREQUISITES
  • Understanding of basic food chemistry
  • Knowledge of milk composition, including milkfat
  • Familiarity with the principles of heat transfer
  • Concept of taste perception and sensory analysis
NEXT STEPS
  • Research the effects of temperature on milk composition
  • Explore the science of emulsification in dairy products
  • Study sensory analysis techniques for flavor perception
  • Investigate the role of fat in taste and mouthfeel
USEFUL FOR

Food scientists, culinary professionals, and anyone interested in the chemistry of food and flavor perception.

When a closed jar of hot milk is dipped in a cool solution and tasted after some time then why does it taste like water at the bottom.
 
Physics news on Phys.org
i don't know about it exactly.
 
I've never experienced this phenomena, but a glass jar is not permeable, so it wouldn't be osmosis. It could simply be that heating the milk forces the milkfat out of solution/suspension.
