“…At wave number 872, 1400, and 1640 cm -1 , transmittances were reduced because of the hemicellulose removal after acid pretreatment, although these peaks remain constant in the PGA milling and MFC centrifugation, which generally alters not chemical structures but surface morphologies. Counterintuitively, CO stretching vibration at 1030 cm -1 increased by higher cellulose concentration [ 25 ]. Therefore, HMFC has the highest peak at this wavenumber because centrifugation increases the solid concentration of MFC.…”

Microfibrillated cellulose (MFC) is a valuable material with wide industrial applications, particularly for the food and cosmetics industries, owing to its excellent physiochemical properties. Here, we prepared high-solid microfibrillated cellulose (HMFC) from the centrifugation of Gelidium amansii -derived MFC right after fibrillation. Dispersion properties, morphology, and structural changes were monitored during processing. HMFC has a five-fold higher solid concentration than MFC without significant changes to dispersion properties. SEM images and FTIR spectra of HMFC revealed a stable surface and structure against centrifugal forces. HMFC exhibited 2,2′-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging activity, although it could not scavenge 2,2-diphenyl-1-picrylhydrazyl (DPPH). Moreover, HMFC inhibited the generation of LPS-induced excessive nitrite and radial oxygen species in murine macrophage RAW264.7 cells. Additionally, HMFC suppressed LPS-induced Keap-1 expression in the cytosol but did not alter iNOS expression. HMFC also attenuated the UVB-induced phosphorylation of p38, c-Jun N-terminal kinase (JNK) 1/2, and extracellular-signal-regulated kinase (ERK) 1/2, as well as the phosphorylation of c-Jun in the immortalized human skin keratinocyte HaCaT cells. Therefore, the application of centrifugation is suitable for producing high-solid MFC as a candidate material for anti-inflammatory and anti-oxidative marine cosmeceuticals.

“…Their research demonstrated that incorporating CNC into a Hestrin-Schramm medium (HSM) can effectively increase the crystallinity of BNC. [204] According to their findings, when the concentration of CNC added to the medium ranged from 0.1 % to 1 %, there was a notable improvement in the CI of BNC, which increased from 51 % to 60 %. This increment indicates that the introduction of CNC into the BNC synthesis environment can have a substantial impact on the structural properties of the resultant BNC, specifically enhancing its degree of crystallinity.…”

Rising global food prices and the increasing prevalence of food insecurity highlight the imprudence of food waste and the inefficiencies of the current food system. Upcycling food by‐products holds significant potential for mitigating food loss and waste within the food supply chain. Food by‐products can be utilized to extract nanocellulose, a material that has obtained substantial attention recently due to its renewability, biocompatibility, bioavailability, and a multitude of remarkable properties. Cellulose nanomaterials have been the subject of extensive research and have shown promise across a wide array of applications, including the food industry. Notably, nanocellulose possesses unique attributes such as a surface area, aspect ratio, rheological behavior, water absorption capabilities, crystallinity, surface modification, as well as low possibilities of cytotoxicity and genotoxicity. These qualities make nanocellulose suitable for diverse applications spanning the realms of food production, biomedicine, packaging, and beyond. This review aims to provide an overview of the outcomes and potential applications of cellulose nanomaterials derived from food by‐products. Nanocellulose can be produced through both top‐down and bottom‐up approaches, yielding various types of nanocellulose. Each of these variants possesses distinctive characteristics that have the potential to significantly enhance multiple sectors within the commercial market.
