If so, it seems like the drying step of the experiment screws up the interpretation of the results. If not, conservation of species mass is violated somehow.
I looked at the chart, this is interesting.
The only thing I could think of, was that the water used was not entirely absorbed during cooking. So even the UA sample had excess water disposed of at the end.
They talk about the lid being open, but that seems not plausible for the amount shown.
