Fuente: WIPO "tomato" The present disclosure provides methods for maintaining freeze-thaw stability of emulsion-based products during preservation at subfreezing temperature and subsequent warming. The method includes isochoric freezing of an emulsion-based product in a fluid using an isochoric chamber at a subfreezing temperature over a preservation time, where the emulsion-based product maintains freeze-thaw stability during the preservation at the subfreezing temperature. Devices for performing the methods are also provided.
