Okra mucilage F, a product of the fruits ofHibiscus esculentus(okra), is a water-soluble, 1.7‐million‐molecular‐weight glycoprotein which produces viscous, shear‐thinning, and viscoelastic solutions in water. Power‐law exponent for okra solutions decreases and viscosity at unit shear rate increases as polymer concentration increases. Limiting viscosity number of okra in water decreases tenfold as the shear rate at which viscosity is measured increases from 1 to450 s−1.
