“…To understand the interaction of ingested boscalid with food products along the GIT microenvironment and to devise a strategy to modulate the interactions to eliminate the ingested boscalid, we employed cellulose nanofibers (CNFs).

Exploitation of nature-derived materials is an important approach to promote environmental sustainability. Among these materials, cellulose is of particular interest due to its abundance and relative ease of access. As a food ingredient, cellulose nanofibers (CNFs) have found interesting applications as emulsifiers and modulators of lipid digestion and absorption. In this report, we show that CNFs can also be modified to modulate the bioavailability of toxins, such as pesticides, in the gastrointestinal tract (GIT) by forming inclusion complexes and promoting interaction with surface hydroxyl groups. CNFs were successfully functionalized with (2-hydroxypropyl)-β-cyclodextrin (HPBCD) using citric acid as a crosslinker via esterification. Functionally, the potential for pristine and functionalized CNFs (FCNFs) to interact with a model pesticide, boscalid, was tested. Based on direct interaction studies, adsorption of boscalid saturated at around 3.09% on CNFs and at 12.62% on FCNFs. Using an in vitro GIT simulation platform, the adsorption of boscalid on CNFs/FCNFs was also studied. The presence of a high-fat food model was found to have a positive effect in binding boscalid in a simulated intestinal fluid environment. In addition, FCNFs were found to have a greater effect in retarding triglyceride digestion than CNFs (61% vs 30.6%). Overall, FCNFs were demonstrated to evoke synergistic effects of reducing fat absorption and pesticide bioavailability through inclusion complex formation and the additional binding of the pesticide onto surface hydroxyl groups on HPBCD. By adopting food-compatible materials and processes for production, FCNFs have the potential to be developed into a functional food ingredient for modulating food digestion and the uptake of toxins.
