Determination of the fiber content of food
Fibers play an important role in human nutrition. The fiber content is generally determined by means of the classic AOAC 985.29 total crude fiber analysis (the so-called Prosky method) and the AOAC 991.43 total crude fiber analysis (applicable for the determination of total crude fiber content in grain, beans, vegetables and fruits and complies with the German "Official analysis procedure L00.00-18 for the determination of total fiber content" in acc. with § 64 LFGB).
Both methods subject the sample to a series of enzymatic digestions that simulate the actual digestion process that takes place in the human and animal digestive system. They calculated the undigested residues that remain at the end of the analysis.
behrotest® temperature controlled water bath with magnetic stirrer
The behrotest® temperature controlled water bath with magnetic stirrer WBMR is used for the simulation of enzymatic digestions, exactly according to these methods. With the multiple digestions of sample copies/duplicates at predefined temperatures using various enzymes (a-amylase for gelification, protease to remove proteins, amyloglucosidase to remove starch). Uninterrupted and even sample mixing (shaking) ensures that the samples do not overheat.
