SUMMARY

The discussion centers on the phenomenon of colored freezy pops turning clear when left outside in extremely cold temperatures, specifically at -20F. Participants noted that the freezy pops, stored in clear plastic, lost their color even after being brought to warmer temperatures. This change is attributed to the effects of extreme cold on the coloring agents used in the pops, which may not withstand such low temperatures. The inquiry highlights a lack of engagement compared to more abstract discussions, indicating a preference for lighter topics over scientific questions.

PREREQUISITES
  • Understanding of food science principles
  • Knowledge of temperature effects on food coloring
  • Familiarity with the properties of polymers in packaging
  • Basic concepts of phase changes in materials
NEXT STEPS
  • Research the impact of low temperatures on food coloring stability
  • Explore the chemical composition of common food dyes used in frozen treats
  • Investigate the properties of plastic materials used in food packaging
  • Learn about the effects of UV exposure on food products
USEFUL FOR

Food scientists, product developers in the frozen food industry, and anyone interested in the effects of temperature on food products.

So this last winter, my roommates and I left a bunch of freezy pops outside to get cold fast (the temp was -20F). They were in clear plastic and may have been exposed to the sun.

After about a day, we went to pick them up, and they had all turned clear. They stayed clear even when brought to warmer temps. Why might this be?

No idea. My freezy pops stay colored even when frozen. But I don't freeze mine to -20 either.
 
Why is it that a thread called "what is time?" got hundreds of replies, when my legitimate scientific inquiry gets one? :cry:

It's more interesting? :wink:
