“…They have several uses in food, medicines, cosmetics, and other commercial items. They are also commonly employed in 3D printing, where they serve several purposes [191,192]. The properties of ink are vital in 3D printing; specifically, 3D printing ink requires a well-regulated viscoelastic response (such as high viscosity and shear thinning behaviour) [193].…”

Cellulose, a linear polysaccharide, is the most common and renewable biopolymer in nature. Because this natural polymer cannot be melted (heated) or dissolved (in typical organic solvents), making complicated structures from it necessitates specialized material processing design. In this review, we looked at the literature to see how cellulose in various shapes and forms has been utilized in conjunction with microfluidic chips, whether as a component of the chips, being processed by a chip, or providing characterization via chips. We utilized more than approximately 250 sources to compile this publication, and we sought to portray cellulose manufacturing utilizing a microfluidic system. The findings reveal that a variety of products, including elongated fibres, microcapsules, core–shell structures and particles, and 3D or 2D structured microfluidics-based devices, may be easily built utilizing the coupled topics of microfluidics and cellulose. This review is intended to provide a concise, visual, yet comprehensive depiction of current research on the topic of cellulose product design and understanding using microfluidics, including, but not limited to, paper-based microfluidics design and implications, and the emulsification/shape formation of cellulose inside the chips.

The Use of Nanocellulose in Edible Coatings for the Preservation of Perishable Fruits and Vegetables

2021

The usage of edible coatings (ECs) represents an emerging approach for extending the shelf life of highly perishable foods, such as fresh and fresh-cut fruits and vegetables. This review addresses, in particular, the use of reinforcing agents in film-forming solutions to tailor the physicochemical, mechanical and antimicrobial properties of composite coatings. In this scenario, this review summarizes the available data on the various forms of nanocellulose (NC) typically used in ECs, focusing on the impact of their origin and chemical or physical treatments on their structural properties (morphology and shape, dimension and crystallinity) and their functionality. Moreover, this review also describes the deposition techniques of composite ECs, with details on the food engineering principles in the application methods and formulation optimization. The critical analysis of the recent advances in NC-based ECs contributes to a better understanding of the impact of the incorporation of complex nanoparticles in polymeric matrices on the enhancement of coating properties, as well as on the increase of shelf life and the quality of fruits and vegetables.

“…Considering their global availability, there is great interest in the conversion of lignocellulosic biomass into the derivative products of cellulose [9]. Cellulose has remarkable characteristics such as tensile strength, elasticity, durability, and in addition to high water absorption and retention capacity, and biodegradability, it is neither toxic nor allergenic; because of these properties it is considered a high potential bio-based material, with versatile applications in wastewater treatment [10], packaging [11,12], food industries [13][14][15], drug delivery systems [16], and tissue engineering [17].…”

Surface Modification of Cellulose from Oat Hull with Citric Acid Using Ultrasonication and Reactive Extrusion Assisted Processes

et al. 2021

This study aimed to produce modified cellulose extracted from oat hulls by an esterification reaction with citric acid (CA) employing ultrasonication and reactive extrusion assisted processes. Modified samples were characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (DRX), scanning electron microscopy (SEM), wettability, oil and water absorption capacities, water adsorption capacity, and thermal stability. From FTIR results it can be observed a new band for all modified samples at 1735 cm−1, confirming the esterification. The morphology and crystallinity pattern of fibers were not affected by esterification, and crystallinity indexes ranged from 43% (unmodified cellulose) to 44–49% in modified samples. Both groups of samples, obtained by ultrasonication and reactive extrusion, showed decreases in water absorption capacities (1.63–1.71 g/g) compared to unmodified cellulose (9.38 g/g). It was observed an increase in oil retention capacity from 1.80 g/g (unmodified cellulose) to 4.57–7.31 g/g after esterification, and also the modified samples presented higher affinity by a non-polar solvent in the wettability test. The new properties of modified cellulose expand its use in the industry and prove that ultrasonication and reactive extrusion can be used to obtain esterified cellulose, being eco-friendly, simple, and convenient processes with short reaction times.
