Summary In this work, we evaluated the effectiveness of the automation capability offered by the ANKOM TDF Dietary Fibre Analyzer to automate the current manual practice of fibre analysis (AOAC Method 991.43). Further, we also validated the automated fibre analysis via cross‐checking with fibre analysis by the manual operation using fruit‐, grain‐ and nut‐based samples. Automated fibre analysis showed relative standard deviations ( TDF : 13.8%; IDF : 17.2%; and SDF : 24.6% at 95% CI reported by the AOAC in the method 991.43) that are consistent to the manual methods. Thus, this current work serves as a valuable assessment of a novel filtration system with disposable filter bag developed by ANKOM Technology. The new instrumentation automates the enzymatic‐gravimetric processing by eliminating several laborious, time‐consuming manual operations, saving over 50% of analyst time that converts to 60% overall cost savings and improved laboratory productivity, efficiency and safety. Industry‐wide adoption of such instrumentation not only reduces the analysis cost but also harmonises the fibre amounts reported among the global food and beverage industry.
