Abstract
Purpose
The purpose of this study was to examine sensory attributes, physiochemical characteristics and consumer preference of drop sugar cookies prepared using high-amylose maize resistant starch (HAMRS) as a replacement for 10%, 20% and 30% of all-purpose (AP) flour as compared to a control made with 100% AP flour.
Design/methodology/approach
A balanced complete block experimental design was used to evaluate the eating quality of the resistant starch enriched cookies using a consumer panel. Consumer preference for the appearance, flavor, texture, moistness and overall acceptability of cookies was assessed. Diameter, height, spread ratio, hardness, moisture, pH, density, surface color and nutrient composition of cookies were analyzed.
Findings
Compared with the control cookies, the HAMRS cookies had lower diameters, higher, heights, reduced spreads, reduced % moisture losses and lower densities (p < 0.001). TA.XT Plus Texture Analyzer showed the HAMRS cookies had a softer texture than the control cookies (p < 0.0001). Evaluation of surface color showed no significant difference in lightness between the control and the HAMRS cookies. The HAMRS cookies were preferred over the control for appearance, texture and moistness in sensory evaluation with 42.5% of panelists choosing the 20% HAMRS replaced cookies as their overall preference. The 20% and 30% HAMRS replaced cookies qualify to be labeled as a “good source” and “excellent source” of fiber, respectively.
Practical implications
This data demonstrates that replacement of up to 30% of AP flour with HAMRS improves eating quality and dietary fiber content of sugar cookies. Our results show that HAMRS has good potential for developing high fiber cookies with minimal adverse impact on physical characteristics and notable improvements in sensory attributes and nutritional value.
Originality/value
To the best of the authors’ knowledge, this is the first study that has reported on the functionality, consumer preference and nutritional value of cookies enriched with a HAMRS that is available to consumers in the form of flour.
