| Abstract: | The paper reports on a method for the detection of nanocellulose (NC) in consumer products by making use of a combination of (a) liquid-liquid extraction with an ionic liquid, and (b) size characterization by asymmetric flow field-flow fractionation (AF4) coupled to multi-angle light scattering (MALS) and refractive index (RI) detection. Both AF4 and MALS are viable tools for characterizing the size of the nanofibers. Sample preparation is easy, and the extraction efficiency of the method is 80.9 ± 1.8% (n = 5). It was applied to the detection of NC in toothpaste and coconut foodstuff to verify the practicability of the method. Graphical abstract Nanocellulose (NC) monitoring from coconut products and toothpaste and its size characterization by liquid-liquid extraction and asymmetric flow field-flow fractionation equipped with multi-angle light scattering and refractive index detection (AF4-MALS-RI). |
