SUMMARY

To calculate the heat required to dehydrate an apple by 90%, one must consider factors such as relative humidity and temperature. While dehydration can occur in low humidity environments without additional heat, applying heat accelerates the process. The discussion references the Backpacking Chef website as a resource for further information on dehydrating fruit effectively.

PREREQUISITES
  • Understanding of thermodynamics related to moisture removal
  • Knowledge of relative humidity and its impact on dehydration
  • Familiarity with temperature control in food processing
  • Basic principles of food preservation techniques
NEXT STEPS
  • Research the specific heat capacity of water to understand energy requirements for dehydration
  • Learn about the effects of relative humidity on the dehydration process
  • Explore methods for measuring and controlling temperature during dehydration
  • Investigate different fruit dehydration techniques and their efficiency
USEFUL FOR

Food scientists, culinary enthusiasts, and anyone interested in food preservation techniques, particularly those focused on dehydrating fruits.

I want to dehydrate a fruit, let say apple, how can I calculate the heat required to dehydrate its water content by 90%.

What data would I need to solve such problem, i.e Relative humidity, temperature etc.

I don't know that you actually need any heat at all. As long as the humidity is low, it should happen. I recently found a perfectly dehydrated chunk of apple under my couch. (I didn't try eating it, because the cat was playing with it, but it looked perfect.)
