Valorisation of vine shoots for the development of cellulose-based biocomposite films with improved performance and bioactivity

Characterization of cardinal vine shoot waste as new resource of lignocellulosic biomass and valorization into value-added chemical using Plackett–Burman and Box Behnken

“…To the best of our knowledge, and according to the recent literature on lignocellulosic biomass from vine shoot waste, it has been used as natural resources of bioactive compounds such as production of lactic acid and lignin [26], resources of phenolic and antioxidant [27,28], cellulose nanocrystals [29], oligosaccharides [30], biobutanol [31], bioethanol [32,33] and bio-composite films [34].…”

Pilot plant scale-up of the production of optimized starch-based biocomposites loaded with cellulosic nanocrystals from Posidonia oceanica waste biomass

“…335 ºC, which has been typically reported to cellulose degradation (Benito-González et al, 2018). In the case of the less purified nanocrystals (NANO F2A), an additional degradation step took place, as indicated by the appearance of a small shoulder at lower temperatures (250-280 ºC), which has typically been assigned to the presence of hemicelluloses (Benito-González, Jaén-Cano, et al, 2020). On the other hand, the degradation step occurring at high temperatures (400-550 ºC) can be attributed to the degradation of lipidic components naturally present in P. oceanica leaves (Benito-González, López-Rubio, Martínez-Abad, et al, 2019) and still remaining in the produced nanocrystals (since the Soxhlet treatment was not applied).…”

“…These have also been exploited to improve the properties of other biopolymer matrices, such as poly(lactic acid) (PLA) (Fortunati et al, 2015;Martínez-Sanz, Lopez-Rubio, & Lagaron, 2012), polyhydroxyalkanoates (PHAs) (Martínez-Sanz, Vicente, Gontard, Lopez-Rubio, & Lagaron, 2015;Martínez-Sanz et al, 2014;Martínez-Sanz et al, 2016), polyisoprene (Siqueira, Abdillahi, Bras, & Dufresne, 2010) and pea starch (Cao, Chen, Chang, Stumborg, & Huneault, 2008), but their production at industrial level should be also tested (Reid, Villalobos, & Cranston, 2017). Furthermore, despite most of the works available on the literature are focused on achieving a complete purification of cellulose from its raw source, a greener simplified method giving rise to less purified cellulosic nanocrystals (containing other components such as hemicelluloses and lipids) has been recently reported, that apart from providing advantages in terms of production costs and environmental impact, also led to improved performance of the derived packaging materials as compared to pure cellulose nanocrystals (Benito-González, Jaén-Cano, López-Rubio, Martínez-Abad, & Martínez-Sanz, 2020;Benito-González, López-Rubio, Gavara, & Martínez-Sanz, 2019;Benito-González, López-Rubio, Gómez-Mascaraque, & Martínez-Sanz, 2020). The reduction on the required purification steps, decreasing the energy and time consumption, can also minimize the economic gap between biopolymers and conventional fossil-fuel derived plastics currently produced at industrial level.…”

Approaches in Animal Proteins and Natural Polysaccharides Application for Food Packaging: Edible Film Production and Quality Estimation

“…The production of films from carboxymethylcellulose (CMC) and cellulose nanocrystals (CNC) is quite common. Cellulose nanocrystals or nanocellulose is a highly crystalline material with improved thermal, mechanical, and barrier properties, and is obtained by acid hydrolysis [ 301 ]. It is noted that the nanofiber of CMC has a negative charge and forms a film in the hydrogel state due to ion crosslinking [ 302 ].…”
