By a flow equation resulting from Maxwell's relation, the equation of state is extended from zero to non-zero quark densities. The impact of the massive strange flavor is considered and implications for cold, charge-neutral deconfined matter in $β$-equilibrium in compact stars are given.REVTEX, 21 pages, 9 figuresHigh Energy Physics - Phenomenologytext
