Innophos is promoting its sodium-free leavening agent Cal-Rise following positive trials on texture, taste and nutrition when used in reduced-sodium tortillas.

The study, carried out for Innophos at the University of Nebraska, evaluated the performance of various sodium-free and low sodium leavenings compared to their traditional SAPP (sodium acid pyrophosphate) and SAS (sodium aluminum sulfate)-based counterparts.

"Formulating with Cal-Rise achieved a dramatic reduction in sodium levels; used as a 1:1 replacement for traditional leavening systems, it enabled a 15-25% cut in sodium content while boosting calcium content," said Innophos. "Finished product height, flexibility and rollability were also very similar among all the samples, although Cal-Rise improved rollability in whole grain tortillas at 30 days."
