I have friends who are chemical engineers for GE and they all said that while there are chemicals that can do what I needed, they are hard to manufacture with.</P><P>As for the comment on adding things to the food, no you wouldn't. When the wrapper for the sticker is opened the oxidation process starts and with the ambient temperature as the process that inhibits or accelerates the reaction.Mon, 20 Feb 2006 08:18:18 GMTBRoddahttp://forums.vcfodder.com/Topic362-83-1.aspxWhat technology exists to do this? Does this require adding something to the food that will interact with the sticker over time?Sat, 18 Feb 2006 18:42:45 GMTBen Rowlandhttp://forums.vcfodder.com/Topic362-83-1.aspxMood ring...

It does this by having the rate of change of the chemicals that make up the sticker decay in direct relation to the temperature. That means food might be green for months in the freezer, but only hours in a hot car.</FONT></P><P class=MsoNormal style="MARGIN: 0in 0in 0pt"><o:p><FONT face="Times New Roman" color=#000000 size=3> </FONT></o:p></P><P class=MsoNormal style="MARGIN: 0in 0in 0pt"><FONT face="Times New Roman" color=#000000 size=3>The process starts when the wrapper is opened and the strip gets the oxygen it needs to begin the reaction. The sticker has a weak adhesive so it can be easily removed from storage containers or it can just be thrown out with aluminum foil.</FONT></P><P class=MsoNormal style="MARGIN: 0in 0in 0pt"><o:p><FONT face="Times New Roman" color=#000000 size=3> </FONT></o:p></P><P class=MsoNormal style="MARGIN: 0in 0in 0pt"><FONT face="Times New Roman" color=#000000 size=3>Needless to say I know some of the problems with this; it’s why I’m fine with posting it here.
