“…Among the four treatment groups, the TSS content of the 0.2% HCS-ZnO nanoparticle composite coating treated group was relatively stable and significantly (p < 0 05) lower than that of the other groups. This result is in accordance with that of the earlier work [55,56].…”

Passion fruits are susceptible to numerous postharvest challenges including weight loss, ethylene production, peel shrinkage, microbial growth, and pulp liquefaction. To mitigate these issues, yellow passion fruits were treated with hydroxypropyl cassava starch zinc oxide (HCS-ZnO) nanoparticles at varying concentrations. Fruits were stored at 10°C for 42 days, and the treated fruits underwent periodic assessments for weight loss, electrical conductivity, reducing sugar, total soluble solids (TSS), titratable acidity, and peel color. The results showed that a 0.8% HCS-ZnO nanoparticle coating could significantly reduce the weight loss of passion fruit during storage. However, compared to other treatments, a 0.2% HCS-ZnO nanoparticle coating demonstrated superior preservation of physicochemical properties, delayed discoloration, slowed ripening, maintained cell membrane integrity (electrical conductivity 1337 μs/cm), and reduced nutrient loss (titrable acidity 3.35 g/100 mL, TSS 17.9%, reducing sugar 5.1 g/100 g) at 42 days of storage. This innovative approach holds promise for commercial application, offering a sustainable solution to mitigate postharvest losses of passion fruit. The study underscores the potential of HCS-ZnO nanoparticles as effective coatings to uphold fruit quality and extend shelf life, presenting compelling insights for future fruit preservation strategies.

“…Chitinases convert the chitin polymer into chitooligosaccharides (COS), which are then converted to N-acetyl-D-glucosamine units by the action of chitobiases [ 5 , 6 ]. COS have several important biological activities, such as antimicrobial, antioxidant, anti-inflammatory, angiotensin I-converting enzyme (ACE) inhibiting, immunostimulating, antitumor, and hypocholesterolemic activities, as well as the ability to enhance the absorption of iron and calcium [ 7 ]. Further, since chitinous waste is generated in abundance, its sustainable valorization is essential to prevent environmental pollution.…”

Chitinases are a large and diversified category of enzymes that break down chitin, the world’s second most prevalent polymer after cellulose. GH18 is the most studied family of chitinases, even though chitinolytic enzymes come from a variety of glycosyl hydrolase (GH) families. Most of the distinct GH families, as well as the unique structural and catalytic features of various chitinolytic enzymes, have been thoroughly explored to demonstrate their use in the development of tailor-made chitinases by protein engineering. Although chitin-degrading enzymes may be found in plants and other organisms, such as arthropods, mollusks, protozoans, and nematodes, microbial chitinases are a promising and sustainable option for industrial production. Despite this, the inducible nature, low titer, high production expenses, and susceptibility to severe environments are barriers to upscaling microbial chitinase production. The goal of this study is to address all of the elements that influence microbial fermentation for chitinase production, as well as the purifying procedures for attaining high-quality yield and purity.

“…Chitosan produce new functionalized derivatives via a grafting reaction [32]. The properties of grafted chitosan are determined by the side chains and the cross-liking agent [33]. Chitin threads are prepared to be used in absorbable suture fabrication, dressing, and biodegradable materials for human skin fiber growth [34].…”

Chitosan is produced by deacetylating the abundant natural chitin polymer. It has been employed in a variety of applications due to its unique solubility as well as its chemical and biological properties. In addition to being biodegradable and biocompatible, it also possesses a lot of reactive amino side groups that allow for chemical modification and the creation of a wide range of useful derivatives. The physical and chemical characteristics of chitosan, as well as how it is used in the food, environmental, and medical industries, have all been covered in a number of academic publications. Chitosan offers a wide range of possibilities in environmentally friendly textile processes because of its superior absorption and biological characteristics. Chitosan has the ability to give textile fibers and fabrics antibacterial, antiviral, anti-odor, and other biological functions. One of the most well-known and frequently used methods to create nanofibers is electrospinning. This technique is adaptable and effective for creating continuous nanofibers. In the field of biomaterials, new materials include nanofibers made of chitosan. Numerous medications, including antibiotics, chemotherapeutic agents, proteins, and analgesics for inflammatory pain, have been successfully loaded onto electro-spun nanofibers, according to recent investigations. Chitosan nanofibers have several exceptional qualities that make them ideal for use in important pharmaceutical applications, such as tissue engineering, drug delivery systems, wound dressing, and enzyme immobilization. The preparation of chitosan nanofibers, followed by a discussion of the biocompatibility and degradation of chitosan nanofibers, followed by a description of how to load the drug into the nanofibers, are the first issues highlighted by this review of chitosan nanofibers in drug delivery applications. The main uses of chitosan nanofibers in drug delivery systems will be discussed last.
