Determination of Alcohol Content in Bakery Products and Baked Goods
The test allows to measure alcohol by volume (ABV) in bakery products and syrup, up to 10 % vol.
Method
Sample treatment
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.
Syrup: Make a dilution 1:100 of the sample using the proper dilution kit.
Principle of the test
Ethanol, in an alkaline environment, is oxidized 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 proportional to the concentration of ethanol in the sample.
