NDF = nopal dietary fiber; PPJ = prickly pear fruit jam; (+) presence, (-) absence; QE, quercetin equivalents. * N × 6.25. Data are the means ± SD of three separate experiments. a Bar significantly different (p < 0.05) from - NDF - PPJ. b P < 0.05 for bar + NDF + PPJ vs +NDF - PPJ. c P < 0.05 tortilla + NDF vs - NDF.
