Adhesion measurements between two blocks of alginate
gel were conducted in air, in distilled water and in a 1M
calcium chloride solution. The top half of the gel rod was
glued (instant super glue 5000—Magic, Australian Adhesives)
to the probe of the Texture Analyser while the
bottom half was glued to either the lower platform of the instrument (experiments in air) or the beaker containing
the water/calcium chloride solution (experiments in wet
environments).
