Flow Properties of Chinese Yam Pulp and its Serum

Abstract

This study was conducted to investigate the flow behaviors of Chinese yam pulp and its serum with a concentric cylinder visco-meter.
Both pulp and serum showed a power law fluid behavior at shear rates ranging from 0.1-20 s^-1. Activation energy of the serum was 1182cal/mol. In addition, serum showed a time dependency, and marked shear decay was observed at shear rates of more than 1.02 s^-1.
