Oleogels are semi-solid materials containing a large fraction of liquid oil entrapped in a network of structuring molecules. In the food industry, these formulations can be used to mimic fats and to deliver bioactive compounds. In the last decade, there has been increasing interest in these structures, not only from a scientific point of view, i.e., studying new molecules, methodologies for gelification, and new structures, but also from a technological point of view, with researchers and companies exploring these structures as a way to overcome certain challenges and/or create new and innovative products. One of the exciting applications of oleogels is the delivery of functional molecules, where the incorporation of oil-soluble functional compounds can be explored not only at the macroscale but also at micro- and nanoscales, resulting in different release behaviors and also different applications. This review presents and discusses the most recent works on the development, production, characterization, and applications of oleogels and other oleogel-based systems to deliver functional molecules in foods.

“…Cristalline nanocelullose has been successfully included in the films of both chitozan (polysaccharide derived from glucan units) and alginate, giving rise to effective interactions and improving the tensile strength [84]. On the other hand, packaging of carboxylated nanocellulose-based hydrogel from lignocellulosic materials has been employed as carrier of pH-sensitive dye for detecting freshness in food products [92]. Despite the enormous advances in studies about nanomaterials as reinforcements, supplementary research is needed in order to facilitate the inclusion of this nanostructure to the polimeric matrix; improve theoretical models to predict mechanical, chemical and thermal properties; and to reduce production costs for these nanocellulose-based struc-tures.…”

The isolation of nanocellulose from different agricultural residues is becoming an important research field due to its versatile applications. This work collects different production processes, including conditioning steps, pretreatments, bleaching processes and finally purification for the production of nanocellulose in its main types of morphologies: cellulose nanofiber (CNF) and cellulose nanocrystal (CNC). This review highlights the importance of agricultural wastes in the production of nanocellulose in order to reduce environmental impact, use of fossil resources, guarantee sustainable economic growth and close the circle of resource use. Finally, the possible applications of the nanocellulose obtained as a new source of raw material in various industrial fields are discussed.

“…For example, a sugarcane-based nanocellulose hydrogel was developed in the form of a pH-responsive freshness indicator that changes color when meat deteriorates. The concept is illustrated in Figure 13 , showing the formation of the Zn 2+ -nanocellulose network prepared by induced gelation of carboxylated CNFs from cellulose filaments [ 44 ]. The nanocellulose hydrogel was used as a carrier for a pH-responsive dye and as a sorbent for CO 2 to improve the color sensitivity of the hydrogel.…”

Nanomaterials obtained from sustainable and natural sources have seen tremendous growth in recent times due to increasing interest in utilizing readily and widely available resources. Nanocellulose materials extracted from renewable biomasses hold great promise for increasing the sustainability of conventional materials in various applications owing to their biocompatibility, mechanical properties, ease of functionalization, and high abundance. Nanocellulose can be used to reinforce mechanical strength, impart antimicrobial activity, provide lighter, biodegradable, and more robust materials for packaging, and produce photochromic and electrochromic devices. While the fabrication and properties of nanocellulose are generally well established, their implementation in novel products and applications requires surface modification, assembly, and manufacturability to enable rapid tooling and scalable production. Additive manufacturing techniques such as 3D printing can improve functionality and enhance the ability to customize products while reducing fabrication time and wastage of materials. This review article provides an overview of nanocellulose as a sustainable material, covering the different properties, preparation methods, printability and strategies to functionalize nanocellulose into 3D-printed constructs. The applications of 3D-printed nanocellulose composites in food, environmental, and energy devices are outlined, and an overview of challenges and opportunities is provided.
