Analog rice made with legumes has more minerals than analog rice made only with maize, as measured by ash content, because legumes naturally contain more minerals than maize.
Mechanism
Synthesis from 1 study
Legumes have more minerals than corn, and when you make fake rice with them, those minerals don’t burn up — they stay behind as ash. So the fake rice with legumes ends up with more ash because it started with more minerals.
Most probable mechanism
When you mix legumes with corn to make fake rice, the legumes bring in more minerals like calcium and iron. When the fake rice is burned in a lab test, those minerals don’t burn away — they turn into ash. So more legumes mean more ash because there’s more mineral stuff left behind.
Legumes contain higher concentrations of inorganic minerals (e.g., calcium, phosphorus, magnesium, iron) compared to maize.
During ash content measurement, organic compounds in the sample are combusted and volatilized, leaving behind inorganic mineral residues.
The increased mineral mass from legume inclusion results in higher residual ash content in the final analog rice product.
