Die Wechselwirkung zwischen Stärke und Reaktivfarbstoffen . Eine neue Untersuchungsmethode in der Stärkeforschung. Teil I. Handelsübliche Farbstoffe, ihre Wechselwirkung mit Stärken und ihre Anwendung in der Stärke‐Mikroskopie

Reaction of Starches with Reactive Dyes. A New Technique for the Investigation of Starches. Part I Reactive dyes can be used for the microscopical detection of damaged or structurally altered starch granules. Stainings of high intensity and contrast can be obtained. The dyes, e. g. of the Levafix E‐type, are chemically bonded to the starch granules and therefore the stainings are permanent. In contrast to the chemical reaction with starches the sorption properties of reactive dyes are similar to those dyes used up until now in starch staining.
