Animal milk is a multicomponent colloidal dispersion that contains fat globules and proteins dispersed in an aqueous continuous phase dissolved sugars minerals. The rapid increase demand production of plant milks, i.e., the plant-based alternatives to animal driven by lactose intolerance, allergens, religious, cultural, environmental, health choices or concerns. Many challenges for emulating milk's physicochemical, functional, sensory attributes can be translated as problems related characterization analysis flow behavior, motivating this study. Only few studies characterize shear rheology almost none show extensional milks (cow goat) (soy, almond, rice, coconut, pea, oat). We find two have rate-independent viscosity responses similar Newtonian fluids. In contrast, except rice milk, display thinning. pinching dynamics response employing dripping-onto-substrate (DoS) protocols we shown are suitable formulations such constant thinning but no measurable elasticity viscoelasticity. last stage pinching, appeared inertiocapillary, power law, elastocapillary whereas displayed viscocapillary response. distinct illustration measurement protocols, discussion role particles, drops, macromolecules presented three key contributions study, aimed at facilitating formulation design more nutritious sustainable future milks.
