Abstract

© 2019 Institute of Food Technologists®Abstract: This study evaluated consumer acceptance and purchase intent (PI) for bread formulated with dried tomato pomace powder (DTPP). DTPP was used to substitute 5 or 10% by weight for a 50/50 mix of white and whole-wheat flour used in a control bread. Consumers (n = 231) evaluated sensory attributes and PI on the breads, which were produced and presented as slices from a typical commercial sandwich loaf. Before answering PI questions, panelists were presented with information regarding the DTPP ingredient. Some received information on nutritional quality, some on sustainability impact, some both, some neither. This approach allowed the impacts of those messages on PI to be tested, along with impact of liking, price, and other factors. PI was analyzed using a fractional logistic model. Statistically significant differences were observed in several sensory attributes, some favoring the DTPP ingredient with overall liking very similar for the 5% DTPP and control bread samples. Price and overall liking were highly significant variables effecting PI. DTPP proved to be an excellent ingredient to replace a portion of wheat flours to improve nutritional value of bread products. Practical Application: This study shows that dried tomato pomace powder (DTPP) has potential application as an ingredient, since it improved nutritional content, appearance, and color appeal of wheat bread. Furthermore, food producers who are considering the use of byproducts in their product formulations should be encouraged by the finding that informed consumers were as willing to purchase the bread with the ingredient, as they were to purchase a typical comparable sandwich bread without it. Furthermore, both a nutrition message and a sustainability message can increase PI for the bread containing the byproduct relative to their PI toward the control bread.
