Three major processes for the refinement of crude carrageenan namely, freezing, isopropanol, and KCl process were developed and evaluated.

Some physical and chemical properties of the product of the different processes were compared to commercial products used as microbiological solid media.

Results have shown that purified carrageenan, having properties similar to that of commercial products, can be locally produced from crude carrageenan. Different processes and parameters can be employed to produce carrageenan with properties that suit the users’ needs. The product of the developed KCl process that used 1.00% (w/v) crude carrageenan and 1:0.5 (w:w) ratio of crude carrageenan to KCl is a probable substitute to imported commercial products used as microbiological solid media.
