Abstract
Foam measurements made with two instruments, the NIBEM-TPH foam
stability analyzer and the NIBEM-CLM foam cling analyzer, have been shown
to be consistent and good predictors of foam quality as perceived
judgmentally. The magnitude of the improvement to foam stability caused by
the additions of bitter acids, zinc, and propylene glycol alginate can be
clearly gauged by this instrumentation.

S�ntesis
Se ha demostrado que la utilizaci�n de dos instrumentos (la analizadora de
estabilidad de espuma NIBEM-TPH y la analizadora de adhesi�n de espuma
NIBEM-CLM) da una buena y consistente correlaci�n con la calidad de la espuma
tal como es juzgado visualmente. La magnitud de la mejora en la estabilidad de
la espuma por el uso de aditivos como cinc, �cidos amargos de l�pulo, y alginato
de propilen glicol puede ser verificada claramente por estos instrumentos.
