Description
Esterase-Lipase test paper is a ready-to-use filter-paper assay for detecting lipases and esterases in milk products and many other foods. The method, originally developed by Prof. Purr in the 1970s and later refined, visualises enzymatic activity by forming an insoluble blue dye on the paper wherever hydrolysis or lipolysis proceeds under suitable conditions. Optimised chemistry has shortened reaction times by about fourfold versus earlier versions, supporting fast, practical screening. Simple handling and a clear colour readout make the strips efficient for industrial quality control of lipolytic spoilage in fats and fat-containing foods such as butter, bakery goods, dried milk products and dry soups. They can also indicate bacterial contamination on raw materials, apparatus or pipelines and help meet food-industry specifications that reference the Prof. Purr lipase-esterase test. Each pack contains 50 test papers from manufacturer Dinkelberg, suited to routine laboratory and production checks where rapid, recognised lipase activity detection is required without complex instrumentation.
This article is part of Test strips & indicator papers, in Test kits & water analysis.

What is this article?
Esterase-Lipase testing paper, 50/Pk Test paper for the detection of lipases and is the article on this page. Luminix Health distributes Dinkelberg for laboratory use. It sits in Test strips & indicator papers, inside Test kits & water analysis, in Lab chemicals.
A test strip or indicator paper changes colour when it meets an ion, a pH or another analyte. It is a fast, coarse reading. The scale printed on the pack is the only scale that strip may be read against. A wet finger contaminates a pH paper before the sample does.
A test kit turns a chemical question into a colour, a titre or a reading on a strip, so the operator does not have to assemble the method from separate reagents. A cuvette test is a ready optical cell. A strip is a field reading. The range printed on the kit is the range where the answer means something. Outside it, the kit is silent or wrong. The substances inside are on PubChem. Water measurement traces to NIST.
