“…Compared with traditional esterification of anhydride or acyl chloride, ethylene ester-based esterification is a mild acid-free reaction. Following similar train of thought, Zhang and co-workers [ 48 ] obtained laurate hemicellulose (LHs) via transesterificaion of hemicellulose with vinyl laurate, using ionic liquid 1-ethyl-3-methylimidazolium acetate as the reaction medium. The introduction of hydrophobic chain greatly improved the solubility of LHs.…”

Globally increasing environmental awareness and the possibility of increasing price and dwindling supply of traditional petroleum-based plastics have led to a breadth of research currently addressing environmentally friendly bioplastics as an alternative solution. In this context, hemicellulose, as the second richest polysaccharide, has attracted extensive attention due to its combination of such advantages as abundance, biodegradability, and renewability. Herein, in this review, the latest research progress in development of hemicellulose film with regard to application in the field of food packaging is presented with particular emphasis on various physical and chemical modification approaches aimed at performance improvement, primarily for enhancement of mechanical, barrier properties, and hydrophobicity that are essential to food packing materials. The development highlights of hemicellulose film substrate are outlined and research prospects in the field are described.

“…Currently, many academic and industrial studies are focused on biodegradable materials in order to replace fossil oil based products, decrease plastic pollution and more broadly safeguard the environment and pay close attention to a sustainable development. (Maaloul, Arfi, Rendueles, Ghorbal, & Diaz, 2017;Nechyporchuk, Belgacem, & Bras, 2016;Lins, Bugatti, Livi, & Gorrasi, 2018;Zhang, Xiao, Chen, Wei, Liu, 2020). The use of agricultural by-products coming from nuts and almonds has been deeply studied (Demirba , 2002;Pirayesh & Khazaeian, 2012): besides of the pruning and other residuals coming from the fields, shells and hulls are the main by-products of the processing of almonds.…”

Lignocellulosic fibres and microcrystalline cellulose have been obtained by simple alkaline treatment from softwood almond (Prunus dulcis Miller (D.A.) Webb.) shells constituting a large agro industrial waste in our territory. The materials have been characterized for the relative composition of lignin and holocellulose, applying a 13C CPMAS NMR spectroscopy methodology. The fibrous material allowed the manufacture of a handmade cardboard obtaining an ecological material suitable for packaging purposes. These fibers along with the obtained microcrystalline cellulose can represent a new fate for the almond shells that are mainly used as firewood.

“…Through continuous research, the utilization of hemicellulose has become possible [ 11 , 12 , 13 ]. Hemicellulose film as packaging material is essentially still in the research stage, although preliminarily applications have been found, e.g., as cover film to keep pepper fresh [ 14 ].…”

“…For example, the contact angle of the hemicellulose film after the citrate esterification and cross-linking can reach 87.5° [ 29 ], and the grafting-modified hemicellulose film has a contact angle as high as 81° [ 30 ]. In addition, the water vapor permeability of lauric acid hemicellulose film [ 14 ] and borate cross-linked hemicellulose film [ 31 ] decreased significantly, and even reached the level of traditional barrier films [ 32 ]. Epoxides have received extensive attention in food packaging materials, and preliminarily applications have been found [ 33 , 34 ].…”

Barrier Film of Etherified Hemicellulose from Single-Step Synthesis

et al. 2020

Hemicellulose with good biodegradability and low oxygen permeability shows great potential in food packaging. However, its strong hydrophilicity leads to its poor moisture resistance, which hinders its wider application. In this paper, a near-hydrophobic hemicellulose was obtained by using single-step synthesis from poplar powder via etherification modification with epoxy chloropropane. This proposed approach has the advantage of avoiding the destruction of hemicellulose structure by secondary alkali-hydrolysis, which was what usually occurred in traditional etherification procedures. The feasibility of using epoxy chloropropane as an alkylation reagent to etherify hemicellulose was confirmed, and the reaction mechanism was elucidated. Contact angle test, thermogravimetric analysis, oxygen transmittance test, and infrared spectrum analysis showed that the barrier property and thermal stability of etherified hemicellulose films have been significantly improved. At an epoxy chloropropane/wood powder ratio (volume/weight) of 2/3 (mL/g), the epoxy hemicellulose films contained the most epoxy groups and displayed the best performance, i.e., tensile strength of 14.6 MPa, surface contact angle of 71.7° and oxygen transmission coefficient of 1.9 (cm3·µm)/(m2·d·kPa), showing great promise as barrier film in food-packaging.
