We have a new home and a new refrigerator. The refrigerator is plugged into a standard outlet and on the same circuit is one GFCI. While using a hand mixer on the GFCI outlet the circuit breaker – not the GFCI – tripped twice and that, of course left us with no power to the refrigerator – until we reset the breaker. We figured the mixer was the problem although we didn't understand why the circuit breaker tripped and not the GFCI. We just aren't comfortable with a situation where we could leave for a few days and come back to a dead refrigerator. Question one is, in new construction these days is the general practice of providing a refrigerator its own circuit no longer an issue? Question two is if the mixer was the problem why wouldn't it trip the GFCI before tripping the circuit breaker?

Refrigeration equipment may be served from another circuit aside from the kitchen circuits but it is not required.
As to why it is tripping the breaker, I think you apparently have too much on one circuit and the addition of the mixer put it over the top. A GFCI trips if current is diverted outside the normal circuit path and the breaker trips if the normal circuit is overloaded. You may have had the microwave or another appliance running with the fridge and mixer.
Moving the fridge to its own circuit would make good sense in this case.
