Abstract
A substrate composition for reaction with an enzyme, comprising carrier particles and a substrate adsorbed thereto and being characterized in that the carrier consists of polyvinylchloride. Polyvinylchloride of emulsion type is particularly preferred. A preferred substrate is tricaproin which is enzymatically split by lipase enzyme. The use of the substrate composition as a substrate component in enzymatic time-temperature indicating devices is also disclosed.
Claims15
A pulverulent enzymatic substrate composition which composition comprises a water-insoluble hydrophobic enzymatic substrate adsorbed on a particulate polyvinyl chloride free of plasticizer and wherein the polyvinyl chloride has an average grain size of at most 0.5 mm, said substrate making up 1-30% by weight of the composition.
