Interlaboratory testing of Insent e-tongues.

Abstract:

:The first interlaboratory testing of electronic taste sensing systems was performed within five participating centers, each working with the Insent (Insent Inc., Atsugi-Shi, Japan) e-tongue. Preparation of the samples for the comprised four experiments, shipping of the samples and evaluation of the results was performed at the University of Duesseldorf. The sensitivity (in this case the difference between lowest and highest sensor response) and slope of the regression line values, obtained within Experiment 1 and 2, have been found to serve as applicable evaluation criterions for interlaboratory comparability. Modified sensor responses could be attributed to aged sensors, but did not influence the results of either Experiment 3, dealing with the evaluation of film formulations, or Experiment 4, dealing with the evaluation of minitablet formulations, in a great amount. Presented PCA Score and Loading Scatter Plots as well as Euclidean distance patterns based on the raw sensor responses confirmed the comparable performance of Insent e-tongues of the participating centers.

  • Mini-tablets versus pellets as promising multiparticulate modified release delivery systems for highly soluble drugs.

    abstract::Whether mini-tablets (tablets, diameters ≤6mm) belong to single- or multiple-unit dosage forms is still questionable. Accordingly, Pharmacopoeial evaluation procedures for mini-tablets are lacking. In this study, the aforementioned points were discussed. Moreover, their potential for oral controlled delivery was asses...
