Color, sensory and textural attributes of beef frankfurter, beef ham and meat-free sausage containing tomato pomace

The present investigation focuses on the textural properties, sensory attributes and color changes of beef frankfurter, beef ham and meat-free sausage produced by different levels of bleached tomato pomace. The texture and color profile were performed using an instrumental texture analyzer and colorimeter. The findings indicated that tomato pomace-added sausages had higher water holding capacity (WHC) compared to that of commercial samples. The frankfurters containing 5 and 7% (w/w) tomato pomace had the highest redness (a*), chroma (C*) and color differences (6,E) values, while the meat-free sausages containing 7% (w/w) tomato pomace had significant (p < 0.05) values for lightness (L*) and yellowness (b*). Furthermore, there were no significant (p > 0.05) color differences between beef ham samples (with and without tomato pomace). A significant progression in the textural hardness and chewiness of systems containing tomato pomace was observed as well as higher sensory scores by panelists. According to sensorial evaluations, bleached tomato pomace improved the consumer acceptability and preference. (C) 2014 Elsevier Ltd. All rights reserved.
