“…So, to fulfill the demand for commercial production, interest has been raised to develop synergy between different processes. In this context, the chemical pretreatment followed by enzymatic hydrolysis has illustrated significant enhancement in COS and GlcNAc production (Trung et al, 2020 ). Pretreatment of chitin before enzymatic hydrolysis not only decreases the crystallinity of the polymer but also makes the substrate readily accessible to the enzyme.…”

Chitooligosaccharides (COS) and N-acetyl glucosamine (GlcNAc) are currently of enormous relevance to pharmaceutical, nutraceutical, cosmetics, food, and agriculture industries due to their wide range of biological activities, which include antimicrobial, antitumor, antioxidant, anticoagulant, wound healing, immunoregulatory, and hypocholesterolemic effects. A range of methods have been developed for the synthesis of COS with a specific degree of polymerization along with high production titres. In this respect, chemical, enzymatic, and microbial means, along with modern genetic manipulation techniques, have been extensively explored; however no method has been able to competently produce defined COS and GlcNAc in a mono-system approach. Henceforth, the chitin research has turned toward increased exploration of chemoenzymatic processes for COS and GlcNAc generation. Recent developments in the area of green chemicals, mainly ionic liquids, proved vital for the specified COS and GlcNAc synthesis with better yield and purity. Moreover, engineering of COS and GlcNAc to generate novel derivatives viz. carboxylated, sulfated, phenolic acid conjugated, amino derived COS, etc., further improved their biological activities. Consequently, chemoenzymatic synthesis and engineering of COS and GlcNAc emerged as a useful approach to lead the biologically-active compound-based biomedical research to an advanced prospect in the forthcoming era.

“…15 A number of studies have been performed to reduce the amount of hydrochloric acid required to achieve <1% residual ash content. [16][17][18][19] It was found that traditionally used concentrations of HCl (3-7%) are in a large excess and much lower concentrations are sufficient. Depending on the thickness of shells and particle size, as well as whether deproteination is performed prior to demineralization, the concentration of HCl may be further reduced.…”

“…CH is a natural, sustainable and biocompatible material with exciting and unique antimicrobial properties, and is used in the pharmaceutical industry, for food packaging, and in environmental conservation [ 30 , 31 , 32 ]. The activity of CH is due to its reactive amino and hydroxyl functional groups, but it is frequently blended with other polymers [ 33 ]. The resistance of bacteria and fungi to chemicals is a major challenge in the treatment of infections, leading to the need for new materials with anti-bacterial properties.…”

The recent interest in food biopackaging is showing an increasing trend, especially in the development of antimicrobial coatings and films. The focus of this study is to assess the potential application of ginger (Zingiber officinale) essential oil (GEO) to polysaccharide films based on chitosan (CHf) and their utilization as an active edible packaging. The films were characterized by different instrumental techniques, and data indicated significant differences (p < 0.05) in the chemical composition of the samples. Forty-seven active compounds from ginger rhizomes were identified in the examined essential oil by gas chromatography mass spectrometer (GC-MS). Fourier transforms infrared spectra (FT-IR) confirmed an interaction between the hydroxyl groups of the phenolic compounds of the essential oil and the amine groups of the bioactive matrix, as shown by the peaks at wavenumbers 1639 cm−1 and 1558 cm−1. X-ray diffraction data suggested a lower crystallinity in the CHf due to the addition of GEO. Differential scanning calorimetric (DSC) analysis revealed that the CHf possessed high thermal stability, especially when different concentrations of GEO were added. The bioactive CHf showed distinct activity against both Gram-positive and Gram-negative bacteria, such as Staphylococcus aureus, Bacillus subtilis, Streptococcus sp., Escherichia coli, Salmonella sp., and Pseudomonas aeruginosa, thus improving the antimicrobial activity to these films. The results provide a comprehensive insight into the importance of films with incorporated EOs as novel types of active food packaging. Antimicrobial food packaging is one of the most promising kinds of active packaging, and acts to reduce, inhibit, or retard any microorganism growth that could contaminate packaged food items.
