Fermentable sugars analysis in cider

CDR CiderLab: the analysis system for cider to perform quality and process controlsWith CDR CiderLab the determination of the fermentable sugars in the cider 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.

The Analyzers CDR CiderLab for determining Fermentable Sugars in Cider

The system is supplied pre-calibrated and ready for use.
Results are expressed in accordance with the reference method.
The reagents have a shelf-life of 18 months
The analytical methods are simple: the system does not require an equipped laboratory or skilled staff.

Two different kits for the determination of fermentable sugar

  • Fermentable Sugar GF (Glucose-Fructose)
    With this kit you can determine the total amount of fermentable sugars: Glucose + Fructose 
  • Fermentable sugars GFS (Glucose-Fructose-Sucrose)
    With this kit you can determine the total amount of fermentable sugars: Glucose + Fructose +  Sucrose


Test type: End Point.
Time testing: one test 6 minutes – 50 Test/hour.
Are possible test sessions with several samples, up to a maximum of 16.
It is also possible to standardize the system using samples with a known value.

Calibration curve

The calibration curve of CDR CiderLab, obtained using reference methods, confirms the excellent linearity of the system over the whole testing range.

Test Principle

Glucose + Fructose + ATP + NAD+reazionezuccherivino ADP + gluconate 6-P + NADH

The glucose and fructose present in the sample are determined enzymatically and therefore are not influenced by the presence of the remaining reducing sugars. The Redox reaction is read at 366 nm (end-point) and the value is directly proportional to the concentration of glucose and fructose in the sample.

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.

Fermentable Sugar GF (Glucose-Fructose)

Code *300384:10 test

Code *300380 : 100 test

Fermentable sugars GFS (Glucose-Fructose-Sucrose)

Code *300815: 10 test

Code *300810 : 100 test (10 buste da 10 test)

Reagent shelf-life 18 months

Processing – Sample Volume – Measuring Range

Cider: use as is or diluted.

Test Measuring range
(g/L of glucose)
Resolution Repeatability
Sugars (glu,fru) [0.1-18 g/L] 0,1 – 18 0,1 0.2
Sugars (glu,fru)[15-350 g/L] 15 – 350 1 3
Sugars (glu,fru, suc)[15-350 g/L] 30 – 350 1 3

*use the appropriate dilution kit for sucrose

To increase the range of measurement repeat the analysis with half of the sample volume and multiply the result by 2. The measuring range can change depending on the absorbance of the cider.
