Water Fraction Effect in the Rheological Behavior of Jalapeno Pepper Pulp

摘要

The shear stress increased with increasing shear rate and decreasing water fraction of jalapeno pepper pulp. Jalapeno pepper pulp behaved as a pseudoplastic fluid and the Herschel-Bulkley and Sisko models described well the shear stress-shear rate behavior, with coefficients of determination greater than 0.999. The parameters of Herschel-Bulkley model, yield stress, consistency index, and behavior index increased as the water fraction of the jalapeno pepper pulp decreased.
