Vinegar

With CDR WineLab®&nbsp;the determination of the fermentable sugars in the wine and must is based on the OIV method, but it is easier and faster. In addition, the reagents have a 18-month stability, while those under the OIV method just over 1 month.CDR made available a new fermentable sugars test, which allows to determine, in addition to the value of glucose and fructose, also the value of sucrose.CDR WineLab® sugar analysis is based on the reference method OIV-MA-AS311-02.&nbsp;This analysis can also be performed on wine vinegar.&nbsp;

<h3>Three different kits for the determination of fermentable sugar</h3><ul><li>Fermentable Sugar&nbsp;GF (Glucose-Fructose) With this kit you can determine the total amount of fermentable sugars: Glucose + Fructose</li><li>Fermentable sugars GFS (Glucose-Fructose-Sucrose) With this kit you can determine the total amount of fermentable sugars: Glucose + Fructose + &nbsp;Sucrose</li><li>Glucose-Fructose With this kit you can determine the&nbsp;value of glucose and fructose separately</li></ul>Fermentable Sugar&nbsp;GF Test type: End Point. Time testing: [uni] minutes

Method

Fermentable sugars GFS Test type: End Point. Time testing: [uni] minutes

Glucose-Fructose Test type: End Point. Time testing: [uni] minutesAre possible test sessions with several samples, up to 16 for CDR WineLab® and 3 tests for CDR WineLab® Junior.<h3>Sample treatment</h3>Wine is analyzed as it is. If necessary (sparkling or fermenting wine), the sample shall be degassed using the specific ultrasonic bath. In case of tests performed on must, the sample shall be first centrifuged or filtered. Dilute the sample if required by the method.

Test Principle

The calibration curve of CDR WineLab®, obtained using reference methods, confirms the excellent linearity of the system over the whole testing range.<figure class="image"><img src="https://s3-foodlab.s3.eu-central-1.amazonaws.com/total_85c9e2c26b.webp" alt="Fermentable sugars Wine: Correlation curve CDR WineLab® method - HPLC method.
