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.

Keywords: bitter acids, foam, instrumental, measurement, perception, propylene glycol alginate, zinc

 

Síntesis
Se ha demostrado que la utilización de dos instrumentos (la analizadora de estabilidad de espuma NIBEM-TPH y la analizadora de adhesión de espuma NIBEM-CLM) da una buena y consistente correlación 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, ácidos amargos de lúpulo, y alginato de propilen glicol puede ser verificada claramente por estos instrumentos.

Palabras claves: ácidos amargos, espuma, instrumentos, medición, percepción, alginato de propilen glicol, cinc
