“…Some of the studies reviewed in this paper rely on theoretical calculations or do not report the total amount of fiber in their results (Fuckerer et al, 2015; Jiang et al, 2005; Koegelenberg & Chimphango, 2017; Michniewicz et al, 1992; Mohebbi et al, 2018; Sahin et al, 2019; Zhang et al, 2019). Moreover, even when gravimetric enzymatic methods are used, outdated methods related to the first definition of fiber, such as AOAC 985.29 (Barros & Franco, 2022; Han et al, 2021; Lazaridou et al, 2022; Magallanes‐Cruz et al, 2020; Paesani et al, 2021; Segundo et al, 2017; Zhang et al, 2019) and 991.43 (Caggia et al, 2020; Irigoytia et al, 2022; Miller & Bianchi, 2017; Sharma et al, 2018), are still widely used. This can lead to inconsistencies in the data, making it challenging to compare results among studies.…”
