Aircraft
[This is] the same aircraft we took in to ZZZ and landed with MAIN PITCH TRIM INOP.  Upon landing; the FO thought he smelled an odor. During taxi; we both started to smell a roasting burning smell. We turned off pack 1 and it dissipated. When we arrived at the ramp; I smelled another burning smell. We turned off pack 2 and it went away again.  After troubleshooting with maintenance; we could not get it to reproduce. Captain recommended replacement all packs and ductwork or investigate more into why a burning smell is such a common issue.
EMB-145 LR flight crew reported a burning smell event upon landing and taxi-in; which dissipated when the Pack 1 was turned off. Maintenance action was assigned.
