Menachot 80: Are the Loaves Obligated as the Thanksgiving Offering is Obligated?

Today's daf discusses why a lost thanksgiving offering cannot be replaced, while if the accompanying loaves are lost, they are replaced.  The loaves are secondary to the sacrifice. 

Perhaps one is only not required to replace the lost sacrifice?  Rashi says that it is permitted to replace the thanksgiving offering.  Masechet Pesachim (13a) discusses this issue as well.  In that case, it is determined that the loaves are attached to the sacrifice, and so they cannot be sanctified.  Instead they lose their holy status and can be sold and eaten. 

The Tsfat Emet speaks about the specific words used to sanctify the loaves.  If the owner says "these are the loaves that accompany the thanksgiving offering" and then the owner sets the loaves aside, then the loaves continue to be his obligation.  Those same loaves can be attached to a replacement thanksgiving offering.
