“…In this context, lignin, the most abundant polyphenol in nature, is increasingly becoming one of the main protagonists since it is recovered in large amounts as a low-cost waste from pulp and paper industry and biorefinery [48]. The low environmental impact of lignin extraction and purification technologies has been reported and discussed, focusing on the expected benefits of lignin as a high added value material [49][50][51]. Current and potential application of lignin has been reviewed [52][53][54][55][56], focusing on power fuel and syngas production (Fischer-Tropsch synthetic fuels), material science and fine-chemicals, specialties, and commodities preparation [57,58].…”

Green, biocompatible, and biodegradable antioxidants represent a milestone in cosmetic and cosmeceutical applications. Lignin is the most abundant polyphenol in nature, recovered as a low-cost waste from the pulp and paper industry and biorefinery. This polymer is characterized by beneficial physical and chemical properties which are improved at the nanoscale level due to the emergence of antioxidant and UV shielding activities. Here we review the use of lignin nanoparticles in cosmetic and cosmeceutical applications, focusing on sunscreen and antiaging formulations. Advances in the technology for the preparation of lignin nanoparticles are described highlighting structure activity relationships.

“…Water content and water activity of cocoa shell samples in the sample that was not treated with HVED. Brahim et al (2017) concluded that high-energy shock waves produced during HVED treatment had induced fragmentation of cellulose. Freeze-dried samples had the lowest water content, but there was no significant difference between cocoa shell mixed with water (WFCS)…”

Cocoa shell is a by-product of the chocolate industry, which is generated in large quantities (700 thousand tons worldwide every year) (Rojo-Poveda et al., 2020). This by-product is rich in insoluble and soluble fibers, proteins, and fat, with a similar fatty acid composition as cocoa butter (Okiyama et al., 2019). In addition, it has a high content of methylxanthines and phenolic components (Barišić, Flanjak, Križić, et al., 2020). Many scientists are investigating the possibilities of using the cocoa shell in food production. There are already studies of the addition of milled cocoa shell in snack products (Jozinović et al., 2019) and functional beverage (Rojo-Poveda et al., 2019) and the addition of soluble dietary fibers obtained from the cocoa shell with the enzymatic process in muffins (Martínez-Cervera et al., 2011) and bread (Collar et al., 2009).The main obstacle to using the cocoa shell in the production of food products is that it contains undesirable components. These components are present because of cocoa bean processing where the cocoa shell is in contact with external pollution. Because of that,

“…Finally, the reported US and HVED were effectively combined with chemical treatments, i.e., NaOH sol. or organosolv (ethanol/water 65% v/v, +1% H 2 SO 4 20%) for RapS delignification (Brahim et al, 2017) [81].…”

Residual biomass from agri-food production chain and forestry are available in huge amounts for further valorisation processes. Delignification is usually the crucial step in the production of biofuels by fermentation as well as in the conversion of cellulose into high added-value compounds. High-intensity ultrasound (US) and hydrodynamic cavitation (HC) have been widely exploited as effective pretreatment techniques for biomass conversion and in particular for cellulose recovery. Due to their peculiar mechanisms, cavitational treatments promote an effective lignocellulosic matrix dismantling with delignification at low temperature (35–50 °C). Cavitation also promotes cellulose decrystallization due to a partial depolymerization. The aim of this review is to highlight recent advances in US and HC-assisted delignification and further cellulose recovery and valorisation.
