“…The plasma was generated with N 2 . The yield of chitin was found to be higher (37.6%) for 6 min treatment of plasma compared to 3 and 1.5 min (25 and 33.2%, respectively) treatment ( Borić et al., 2018 ). It is reported to be an effective and sustainable form of pre-treatment for removing invaluable compounds.…”

Uncontrolled decomposition of agro-industrial waste leads to extensive contamination of water, land, and air. There is a tremendous amount of waste from various sources which causes serious environmental problems. The concern in the disposal problems has stimulated research interest in the valorization of waste streams. Valorization of the wastes not only reduces the volume of waste but also reduces the contamination to the environment. Waste from food industries has great potential as primary or secondary feedstocks for biopolymer production by extraction or fermentation with pre-treatment or without pre-treatment by solid-state fermentation to obtain fermentable sugars. Various types of waste can be used as substrates for the production of biomaterials but recently more focus has been observed on the agro-industrial wastes which have a high rate of production worldwide. This review collates in detail the different food wastes used for biopolymer, technologies for the production and characterization of the biopolymers, and their economic/technical viability.

“…The chitin content can widely vary between different sources, ranging from 16–23% in lobster shells, 25–30% in crab shells and 34–49% in krill shells to 18–38% in cockroach cuticles, 22–64% in butterfly cuticles, 20–44% in silkworm, 8–43% in mushrooms cell walls, 8–27% in mold cell walls and 1–3% in yeast cell walls [ 33 ]. Whereas crustacean exoskeletons are not usually employed by the food industry and are considered waste [ 35 ], and chitin from fungi is also often extracted from residues [ 36 ], chitin from insects can be ingested together with other nutrients because they are usually consumed as whole insects or parts of whole edible insects including ingredients derived from them such as meals/flours [ 4 ]. As consumer acceptance in developed countries remains one of the barriers to their use as an entire food [ 37 ], the inclusion of insects as flours or other forms of food, for example, cookies, energy bars, hamburgers and sandwich spreads, among others, is promising [ 38 ].…”

The human gut microbiota has been revealed in recent years as a factor that plays a decisive role in the maintenance of human health, as well as in the development of many non-communicable diseases. This microbiota can be modulated by various dietary factors, among which complex carbohydrates have a great influence. Although most complex carbohydrates included in the human diet come from vegetables, there are also options to include complex carbohydrates from non-vegetable sources, such as chitin and its derivatives. Chitin, and its derivatives such as chitosan can be obtained from non-vegetable sources, the best being insects, crustacean exoskeletons and fungi. The present review offers a broad perspective of the current knowledge surrounding the impacts of chitin and its derived polysaccharides on the human gut microbiota and the profound need for more in-depth investigations into this topic. Overall, the effects of whole insects or meal on the gut microbiota have contradictory results, possibly due to their high protein content. Better results are obtained for the case of chitin derivatives, regarding both metabolic effects and effects on the gut microbiota composition.

“…Recently, our group proposed a unique solvent-less highly efficient option using the plasmabased methodology to pre-treat the crustacean shell waste, while allowing an intensified protein removal. This renewable electricity-based separation can serve as a scalable green alternative to the conventional chemical deproteinization step applying unrecyclable mineral bases [13]. Another alternative is the selective extraction of chitin with deep eutectic solvents (DES), since these have already shown great potential as dissolution media for some hardly soluble biopolymers, including cellulose, lignin and starch [14][15][16].…”

AbstractThis study provides a complete evaluation of a sustainable zero-waste process for the recovery of added value biomaterials from the abundant shrimp shell biomass waste using natural deep eutectic solvents (NADES). The process parameters for the fractionation of α-chitin, minerals and protein was followed using on-line measurements. Furthermore, the quantitative analysis of isolated chitin, minerals and solvent waste streams were examined. The dominant fractionation mechanisms are explained through the analysis of the liquid and solid fractions. Four of the most promising, and commercially available, NADES consisting on mixtures of Choline Chloride-Lactic Acid (CCLA), Choline Chloride-Malonic Acid (CCMA), Choline Chloride-Urea (CCUR) and Choline Chloride-Citric Acid (CCCA), were tested. The highest chitin extraction yield obtained was < 90% using CCLA, leading to purity higher than 98%. Moreover, it is possible to recycle this particular NADES several times, while having no loss in the shrimp shell fractionation capability.
