Scientists at the Institute of Food Research, Norwich, UK, examined the growth of polymer mass of polygalacturonic acid-based multilayers using a range of acoustic and optical techniques.
The comparative study showed that the different techniques give quantitatively different results when used to measure what is nominally the same quantity (multilayer hydrated mass and polymer mass).
