  In this work interacting Umami Chaplygin gas has been studied in flat FRW
model of universe in context of it's thermodynamic and dynamical behaviour. In
particular, considering Umami fluid as dark energy interacting with dark
matter, irreversible thermodynamics has been studied both for apparent and
event horizon as bounding horizon in two separate cases. Also the model has
been investigated in purview of dynamical systems analysis by converting the
cosmological evolution equations to an autonomous system of ordinary
differential equations. With some restrictions on model parameter $\omega$ and
coupling parameter $\lambda$, some cosmologically interesting critical points
describing late time accelerated evolution of the universe attracted by
cosmological constant and accelerated scaling attractor in quintessence era
have been found to alleviate coincidence problem.
