“…Therefore, some researchers have combined an acid and glycerol to produce chitin. Hong et al [32] used a glycerol and HCl co-solvent to achieve demineralization and deproteinization at low temperature for one-step production of chitin from lobster shells. Although HCl was used in this method, the acid amount was lower than that required for the conventional method.…”

Chitin biomass, a rich renewable resource, is the second most abundant natural polysaccharide after cellulose. Conversion of chitin biomass to high value-added chemicals can play a significant role in alleviating the global energy crisis and environmental pollution. In this review, the recent achievements in converting chitin biomass to high-value chemicals, such as 5-hydroxymethylfurfural (HMF), under different conditions using chitin, chitosan, glucosamine, and N-acetylglucosamine as raw materials are summarized. Related research on pretreatment technology of chitin biomass is also discussed. New approaches for transformation of chitin biomass to HMF are also proposed. This review promotes the development of industrial technologies for degradation of chitin biomass and preparation of HMF. It also provides insight into a sustainable future in terms of renewable resources.

“…Therefore, the thermal stability of the DES 100-1 and pristine chitin was studied using TGA and the DTG analysis, as shown in Figure 4b. The thermal stability of chitin is affected by its crystallinity, molecular weight, particle size, and source [3,4,6,62]. The start decomposition temperature (T start ), onset decomposition temperature (T onset ), and maximum weight-loss rate temperature (T max ) were 198, 343, and 389 • C for pristine chitin and 210, 340, and 386 • C for DES 100-1 , respectively.…”

“…Chitin, which consists of poly-β-(1-4)n-acetyl-D-glucosamine, is the second most abundant biopolymer in nature after cellulose. It can be obtained from renewable marine sources (i.e., sponges) [1] as well as different feedstock, such as crustacean shells [2][3][4][5], spiders [6][7][8] and insect cuticles [6], and some cell walls of fungi and diatoms [9], in which it plays an important role in the skeleton of these biological structures. Chitin has many appealing characteristics, such as nontoxicity, sustainability, biocompatibility, and biodegradability, and it has attracted notable attention during recent years.…”

“…Numerous studies have been conducted to extract or optimize the extraction conditions of chitin from a variety of sources [3][4][5][6]22,23], but only few solvents can be used for dissolving or dispersing chitin for further processing [24]. However, when the size of chitin is reduced to nanoscale, it readily disperses in water under acidic or even neutral conditions [25].…”

Efficient Hydrolysis of Chitin in a Deep Eutectic Solvent Synergism for Production of Chitin Nanocrystals

A deep eutectic solvent (DES) derived from ferric chloride hexahydrate and betaine chloride (molar ratio of 1:1) was used as hydrolytic media for production of chitin nanocrystals (ChNCs) with a high yield (up to 88.5%). The synergistic effect of Lewis acid and released Brønsted acid from betaine hydrochloride enabled the efficient hydrolysis of chitin for production of ChNCs coupled with ultrasonication with low energy consumption. The obtained ChNCs were with an average diameter of 10 nm and length of 268 nm, and a crystallinity of 89.2% with optimal synthesis conditions (at 100 °C for 1 h with chitin-to-DES mass ratio of 1:20). The ChNCs were further investigated as efficient emulsion stabilizers, and they resulted in stable o/w emulsions even at a high oil content of 50% with a low ChNC dosage of 1 mg/g. Therefore, a potential approach based on a DES on the production of chitin-based nanoparticles as emulsifiers is introduced.

“…The use of melt-blending techniques is, however, environmentally benign, costeffective, best for mass production and toxin-free since it does not require the use of a solvent unlike in the electrospinning process. Besides, processing PLLA via melt-blending helps in pores formation necessary for cell differentiation and proliferation [8] in any biological system. The melt-blending method was used to produce polymer composites with both organic and inorganic reinforcements with enhanced mechanical properties.…”

The struggle in osteosynthesis continues with the search for more biocompatible materials to replace metallic scaffolds. Poly(L-lactic) acid (PLLA), a biopolymer, was processed via melt-blending technique by blending chitosan and Ti-6Al-2Sn-2Mo-2Cr-0.25Si powders with it in varying compositions at 290 oC. The microhardness values, compressive moduli and fracture toughness of the reinforced PLLA improved significantly while the resulting composites were found to be less tough than the unreinforced PLLA. Compressive moduli obtained were much lower than the modulus of cortical bone. They were, however, mechanically compatible with the properties of cancellous bone.
