Determination of Anthocyanins in Wine and Must

CDR WineLab analysis system fast, simple to use and reliable for determining multiple parameters in wine and mustAnthocyanins are chemical compounds present in the peel of grapes, whose color changes depending on the acidity of the surrounding environment. They are part of the polyphenol group.

The method of CDR WineLab®, that is based on the same principle of the Glories method, simplifies and speed the procedure of extraction and the analytical process. In this way is possible to esteem the extraction of the antocyanes from the must directly in wine cellar without the necessity of executing the determination in an equipped laboratory with skilled staff. The time required for the extraction is about 1 hour. The reading is immediate.

Anthocianins In Must with CDR WineLab Correlation with Cyanidin Glucoside Reference Method

Test Principle

The total anthocyanins present in wine and must, in a very acid environment (pH 1), develop a specific color whose intensity, measured at 505 nm (end-point), is directly proportional to the concentration in the sample expressed in mg/L.

Reagent test Kits

The reagents are packaged in foil pouches containing 10 tubes useful to perform 10 analyses.

This is the minimum package that allows the use of CDR systems even to those who need to make a few analyses, thus not wasting reagents.

There are also boxes of 100 tests, however, packaged in 10 bags of 10 tubes containing the reagent.
