“…4. It is evident that the diffractograms of HSC and HSM exhibited sharp peaks at around 18° and 22.5° 2 θ angles; these peaks were attributed to the diffraction planes of 110 and 002 33,34 such are typical of cellulose I crystal form; moreover, there was no doublet in the main peak at 2 θ (22.5°). The crystallinity index of HS was found to be 24.74 %, this value increased in HSC to 59.03 %, and 59.17 % in HSM, suggesting an increase in the intra-and intermolecular hydrogen bonding, which occurs as amorphous HS is transformed into cellulose I.…”

“…This modification may have broken the reticulation of HSC. 46 The higher water holding capacity of HSC over HSM suggests the possible use of HSC in food applications requiring moisture retention as low-calorie bulk ingredients 34 , whereas HSM may have potential applications in fields such as paper and pulp, water treatment (adsorbents), and pigments, where low moisture retention is required. Water holding capacity of materials is dependent on several factors such as inherent chemical and physical structure.…”

“…34 Aside the functional groups, both HSC and HSM have a network-structure, which is much more compact in the case of HSC than in HSM; thus, from their network-structure, they also have the tendency of being able to trap metal ions.…”

Grafting of ethylenediamine onto Hibiscus sabdariffa cellulose was achieved via the simple reaction mechanism. The modified Hibiscus sabdariffa cellulose (HSM) and unmodified Hibiscus sabdariffa cellulose (HSC) were characterized using Fourier transformed infrared (FTIR) spectroscopy, elemental analysis, scanning electron microscopy (SEM), X-ray diffraction (XRD), particle size distribution, zeta potential, thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC). Both HSM and HSC were also analysed for their water holding capacity, oil holding capacity, swelling capacity, and heavy metal adsorption capacity. The particle size distribution of HSC was found to be monomodal, while that of HSM was bimodal. HSM performed better than HSC in terms of oil adsorption capacity and metal adsorption capacity especially for Pb 2+ and Cd 2+ ions. HSM also performed better than some reported cellulosic materials found in literature. These properties exhibited by HSM present it as a potential resource in the food industry and in treatment of heavy metal contaminated water.

Functional and engineered colloids fabricated from edible materials have recently gained a lot of interest for futuristic applications in the field of foods for purposes ranging from microstructure development to delivery of healthpromoting bioactives to manipulation of food-body interactions. This review tackles a very ambitious task of discussing the current understanding of functional colloids within the framework of foods. Physicochemical attributes of several novel complex colloids fabricated from natural, and often, underutilized edible materials are clearly and comprehensively reviewed in this paper. This review not only provides a scientific insight into the advances made in the field of colloid-based food structuring but also touches on the exciting future opportunities in this promising multidisciplinary field.
