摘要：
In this work the rheological characteristics of tomato pastes obtained by both hot break and cold break method were evaluated. Results demonstrated that the products examined had a pseudoplastic behavior, which can be described by the power-law equation. Two mathematical models were proposed to calculate K (consistency coefficient) and n (flow-behavior index) as a function of the Bostwick values (Bk), Brix degrees (degrees Bx), and temperature. These models, in addition to easy and rapid analyses, were useful to estimate the essential rheological parameters for fluid dynamics dimensioning of production plants for tomato products.
