Using the linear Ali Das Vagenas GUP, which alters both the phase-space measure and the single-particle dispersion relation, the corresponding deformed particle current is constructed and its flux across a freeze-out hypersurface is evaluated. The resulting invariant spectrum acquires a momentum-dependent correction governed by a single dimensionless function that enhances high-momentum modes. For a static, homogeneous hypersurface the full expression can be written in closed analytic form, and the structure of the correction allows straightforward implementation in blast-wave-type models. The result is also directly relevant to holography-informed heavy-ion modeling, where gauge/gravity duality constrains the strongly coupled plasma dynamics but the conversion to hadron spectra is still performed through a Cooper-Frye freeze-out map.  Our findings demonstrate that Planck-scale deformations of quantum mechanics can leave characteristic imprints on freeze-out observables, opening a novel avenue for constraining GUP scenarios with heavy-ion data. https://jhap.du.ac.ir/article_2074_9c60f4357530cc8907b90779f2a16a42.pdf
