Determination of Alcohol Content in Bakery Products and Baked Goods

CDR FoodLab®: the analysis system to perform a complete quality control on bakery products, snacks and spreads.

With CDR FoodLab® you can determine easily and quickly the alcohol percentage of the bakery products and baked goods in order to verify the compliance with the law.

Moreover, with CDR FoodLab® it is possible to determine the alcohol concentration of the alcoholic solutions used as preservative and antibacterial agent.

The Analyzers CDR FoodLab® for a complete quality control on bakery products, baked goods, snacks and spreads.

The system is supplied pre-calibrated and ready for use.
Results are expressed in accordance with the reference method.
The analytical methods are simple: the system does not require an equipped laboratory or skilled staff. You can perform the test even at production line.

Test Principle

Ethanol + NAD+ Test principle of alcohol analysis in wine Acetic Aldehyde + NADH
Ethanol is oxidized in an alkaline environment through an enzymatic reaction and converted in acetic aldehyde in presence of NAD+, which in turns produces NADH. The increase of the absorbance, measured at 366 nm (end-point) is directly proportional to the concentration of ethanol 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.

Code *300606: 10 tests

Code *300608: 100 tests

The reagents have a shelf-life of 6 months

Sample Processing 

Finished product: add to a defined amount of grinded product the quantity of distilled water indicated in the method that brings the alcohol in solution. After an easy centrifugation you obtain a limpid solution that can be analysed.

With the CDR system, you can perform your tests in total autonomy

Neither skilled staff nor a dedicated external laboratory is needed to use our systems. CDR FoodLab® optimizes traditional testing methods, making them faster and easier, while guaranteeing accuracy standards in line with the reference methods.

Analytical kit

CDR FoodLab® Analysis Systems use disposable pre-vialed reagents specifically developed by the research laboratories of CDR. The use of pre-vialed reagents and the analytical procedures allow:

  • a sample preparation that is quick and easy, when needed at all;
  • making analytical procedures extremely fast and easy;
  • removing all needs for complex calibration procedures.

Reagents come in aluminum packages containing 10 test tubes each to perform 10 tests (or packages for 100 tests containing 10 single packages of 10 test tubes each).

Just a few steps and results are yielded right away

Just a few steps will suffice to carry out your analysis in a rapid way in total autonomy. The system is composed of both the analyzer based on photometric technology and a kit of low toxicity, pre-vialed reagents, developed by CDR.

CDR FoodLab® is cost-effective because it does not require the use of expensive equipment and does not entail maintenance, assistance or calibration costs.
