You can use the variable instead.

So instead of:

alias foo="echo test"

use:

foo="echo test"

then execute it either by command substitution or eval, for instance:

find . -type f -exec sh -c "eval $foo" \;

or:

find . -type f -exec sh -c "echo `$foo`" \;

Here is real example which is finding all non-binary files:

IS_BINARY='import sys; sys.exit(not b"\x00" in open(sys.argv[1], "rb").read())'
find . -type f -exec bash -c "python -c '$IS_BINARY' {} || echo {}" \;
