| Abstract:
Consistency is a determinant factor in tomato products, since viscosity is an important cost factor in paste utilisation for formulation of final consumer products. Alcohol-insoluble solids, pulp content, acid-detergent fibre, and calcium. components known to be involved in consistency, were evaluated at different points of a tomato paste processing line under cold, hot, and high viscosity hot break conditions to determine how these components are affected by the different steps of paste manufacturing (cutting, breaking, pulping, evaporation). From this study it can be concluded that the conditions of breaking and pulping/finishing determine the changes in the fractions involved in paste consistency, whereas concentration affects aggregate formation and polymer chemistry. | |
