Bakery products

With CDR FoodLab® you can determine easily and quickly, without the use of solvents, the percentage of alcohol contained in bakery products and baked goods and syrup, the alcoholic solution used on the product as a preservative and antibacterial.The test allows you to measure the alcohol content in baked and wet products, up to 10% vol.

Determination of Alcohol Content in Bakery Products and Baked Goods

CDR FoodLab® is the chemical analyzer for quality and process control that allows you to determine a wide range of parameters of many foods, animal feeds and pet foods. 

Endpoint analysis. Analysis time: [uni]. Are possible test sessions with several samples, up to 16 for CDR FoodLab® and 3 tests for CDR FoodLab® Junior.<h3>Sample treatment</h3>Bakery products: Crumble the finished product, weigh 5 grams in a container and add 100 grams of distilled water. Mix thoroughly the mixture and centrifuge at 5000 rpm for about 3 minutes.&nbsp; Syrup:&nbsp;Make a dilution 1:100 of the sample using the proper dilution kit.

Method

The increase of the absorbance, measured at 366 nm (end-point) is directly proportional to the concentration of ethanol in the sample.

Test Principle

The CDR FoodLab® results are reliable as they are correlated to those once obtained by the reference method. The graph below shows the great correlation between CDR FoodLab® and the reference method.<figure class="image"><img src="https://s3-foodlab.s3.eu-central-1.amazonaws.com/Alcol_7126169bb7.jpg" alt="Calibration curve with the reference method of the analysis of the alcohol content in baked goods.
