#### Abstract

Rheological behaviors of red pepper paste acre investigated with rotational viscometer at $25{\sim}55^{\circ}C$ and the following results were obtained. 1. At shear rate of $0.323{\sim}1.653\;sec^{-1}$, red pepper paste was found to be a thixotropic food product which showed pseudoplastic proper ties and also exhibited a yield stress and time dependent characteristics. 2. At a shear rate of 0.978 $sec^{-1}$, flow behavior index, consistency index and yield stress were 0.597, 192.3 dyne $sec^s/cm^{2}$, and 91 dyne/$cm^{2}$ respectively. 3. Variation of consistency of red pepper paste with time was found to be decayed by a second order kinetic equation and thereafter nearly time independent. 4. Variation of consistency of red pepper paste with temperature was found to follow Andrade's equation and the activation energy as calculated on the basis of this equation was $1.03\;kcal/g{\cdot}mole$.
