“…The biodegradation of PVA film was at 61%. Given the fact that PVA is a biodegradable synthetic polymer, it exhibits high microbes' activity during the soil burial degradation process 46 . The degradation degree of PVA/CS blend was higher than that of PVA film after 30 days of burial in the soil.…”

The food industry's ever‐increasing need to substitute synthetic packaging materials has led to the development of eco‐friendly alternatives with improved physical and mechanical properties. The main objective of this work relates to the effect of adding different weight fractions (1, 3 and 5 wt%) of cellulose nanocrystals (CNC) and cellulose nanofibrils (CNF) on the morphological, thermal, structural, biodegradable and mechanical properties of PVA/Chitosan (CS) bio‐nanocomposites. The DSC and FTIR results reveal that PVA and Chitosan are compatible due to the strong interactions via hydrogen bonding, which are also proved by the tensile test. The water solubility test indicates the biodegradability of nanocomposites. Furthermore, CNF have significantly enhanced the mechanical properties of PVA/CS. Hence, PVA/CS/CNF nanocomposites can be efficiently utilized for bio‐based packaging materials, where good mechanical properties are prime requirements.

“…Modified chitosan is widely used in biomedical engineering, agriculture, food, and other fields. [ 120 ] To date, chitosan has achieved numerous gene transfection at mammalian cell levels (e.g., primary chondrocytes [ 121 ] and epithelial cells [ 122 ] ) and animal levels. [ 123 ] Besides, chitosan nanoparticles are also widely used in plant science.…”

Plant genetic engineering is essential for improving crop yield, quality, and resistance to abiotic/biotic stresses for sustainable agriculture. Agrobacterium‐, biolistic bombardment‐, electroporation‐, and poly(ethylene glycol) (PEG)‐mediated genetic‐transformation systems are extensively used in plant genetic engineering. However, these systems have limitations, including species dependency, destruction of plant tissues, low transformation efficiency, and high cost. Recently, nanotechnology‐based gene‐delivery methods have been developed for plant genetic transformation. This nanostrategy shows excellent transformation efficiency, good biocompatibility, adequate protection of exogenous nucleic acids, and the potential for plant regeneration. However, the nanomaterial‐mediated gene‐delivery system in plants is still in its infancy, and there are many challenges for its broad applications. Herein, the conventional genetic transformation techniques used in plants are briefly discussed. After that, the progress in the development of nanomaterial‐based gene‐delivery systems is considered. CRISPR‐Cas‐mediated genome editing and its combined applications with plant nanotechnology are also discussed. The conceptual innovations, methods, and practical applications of nanomaterial‐mediated genetic transformation summarized herein will be beneficial for promoting plant genetic engineering in modern agriculture.

“…Cellulose nanocrystals (CNC) and microcrystalline cellulose (MCC) are cellulose derivatives extracted by strong acid hydrolysis (Mu et al., 2019). CNC has been extracted from sources such as wood (Chen et al., 2015), mango (Cordeiro et al., 2014; Dey et al., 2021), apple (Melikoğlu et al., 2019), and rice straw (Perumal et al., 2018). Similarly, extraction of MCC from groundnut shells (Trache et al., 2016), soybean hulls (Merci et al., 2015), and jute (Jahan et al., 2011).…”

The inclusion of cellulose nanocrystals (CNC) and microcrystalline cellulose (MCC) during extrusion processing of corn starch (CS) is presented in this study. Blends were prepared by incorporating CNC and MCC at different concentrations, 1%, 3%, 5%, and 10% w/w in CS. The crystallinity index (CrI) of CNC and MCC was determined using X-ray diffraction, and the chemical functionality of CNC, MCC, and CS was studied using Fourier transform infrared spectroscopy. The pasting properties of the blends were studied using Micro Visco-Amylo-Graph before extrusion. The blends were preconditioned to 18 ± 0.5% (w.b.) moisture and extruded using a twin-screw extruder at 200 and 250 rpm at 140 • C. CS-CNC's expansion ratio (ER) values were 2.95 to 3.35 and 2.72 to 3.22 for MCC. CNC's CrI and particle size were significantly lower than MCC, allowing CNC-based extrudates to have ER values similar to the control even at high CNC concentration (≤10% w/w). This study demonstrated that fiber with particle size <100 µm can be added in direct-expanded product formulations at high concentrations without negatively influencing the extrudate texture while offering increased nutritional value. K E Y W O R D Scellulose fibers, direct-expanded products, extrusion expansion, extrusion processing, starch Practical Application: This study gives insight into the potential application of cellulose nanocrystals and microcrystalline cellulose in manufacturing direct-expanded extruded products, providing high fiber content without compromising the product quality. This knowledge could also be translated into manufacturing other food products such as breakfast cereals, pasta, and bread.
