Recrystallization inhibition assessed by splat cooling and optical recrystallometry.

Levels of recrystallization have been measured by two distinct techniques; a splat cooling assay and a new device, an optical recrystallometer, which measures the change in light transmittance through a frozen sample. Both techniques indicate the presence of recrystallization inhibitors in a grass extract and in other samples. The advantages of each method of measuring recrystallization are discussed.
