“…This could be due to the microemulsification of TaEO, which might effectively activate the CAT enzyme system of loquat fruit. A similar effect of essential oils on CAT activity was reported for cherry tomato fruit [54]. POD is a key enzyme involved in the oxidative stress-induced enzymatic defense system [55].…”

Loquat is a nutrient-rich fruit with juicy and sweet pulp, but it is vulnerable to rot and deterioration without proper postharvest preservation measures. This study aimed to improve the postharvest quality of loquat by developing a microemulsion system based on an essential oil extracted from the Torreya grandis cv. Merrillii aril (TaEO), which has antimicrobial and antioxidant properties. An optimal TaEO microemulsion (TaEO-ME) was formulated, using a mixture of Tween-40 and Tween-80 as the surfactant, 1-butanol as the co-surfactant, and TaEO as the oil phase, with mass ratios of 9:1, 3:1, and 6:1, respectively. Two TaEO-ME formulations with 60% and 70% water contents were stable for 180 days at room temperature, with a mean droplet size below 12 nm and polydispersity index less than 0.24. They also exhibited higher stability and enhanced biological activities compared to free TaEO. Loquat fruit treated with TaEO-ME displayed a reduced decay index and lower membrane lipid peroxidation after 15 days of storage at 15 °C, as indicated by the lower malondialdehyde content and higher peroxidase activity. Moreover, the TaEO-ME treatment preserved the nutrient quality by maintaining the total phenolic compounds and ascorbic acid content. Our findings suggested that TaEO-ME can be used as a substitute for chemical preservatives to keep fruits fresh.

“…As previously said, the fruits are retained at room temperature, which may make water loss a major influence factor for weight loss. 41 The water evaporation of oranges was effectively reduced due to the encapsulation of CSCs. As expected, CSCs played a better barrier role in quality retention.…”

The packaging of fresh foods is increasingly focusing on biodegradable composites made from natural resources. Environmental worries about traditional plastics can be reduced by developing robust, eco-friendly biocomposites. Here, carboxymethyl chitosan (CMCS) was co-solubilized with cellulose to successfully fabricate highly transparent, sturdy composite films (CSCs). All composite films exhibited better thermal stability, high transparency, and robust mechanical strength due to physical cross-linking and hydrogen bonds between homogeneously dispersed CMCS and cellulose molecules. Particularly, compared to CSC-0, the tensile strength and elongation at break of CSC-3 were increased by 68.8 and 23.2%, respectively. Additionally, CSCs showed excellent barrier capacity and good antibacterial ability for suitable food packaging materials. These CSCs with excellent properties can be used to package fruit to reduce water loss from the fruit and increase its shelf life.

“…Recently, encapsulation of essential oils into O/W Pickering systems enhanced their compatibility with the CS membrane matrix and improved their dispersibility efficiently. 18 Another important factor is that the Pickering emulsions stabilize the controlled release of the oil phase while delaying limonene diffusion. Among various emulsion stabilizers, cellulose nano-materials extracted from the ubiquitous bioresources on earth offer a promising substitute for traditional surfactants to develop safe, sustainable and environmentally friendly Pickering emulsion systems.…”

Due to the perishable nature and limited shelf life, it is crucial to develop highly efficient techniques for fruit preservation while avoiding the use of environmentally hazardous materials. Herein, the ecofriendly oxidized cellulose nanofibers (OCNF) with an optimized solid content (1.0 wt %) was utilized to stabilize d-Limonene to form an oil-in-water Pickering emulsion. By incorporating the Pickering emulsion into chitosan (Cs) solution, fully biobased Cs/OCNF@d-Limonene coatings were successfully obtained via a simple solvent casting method. Thanks to the physical cross-linking and hydrogen bond reaction between OCNF and Cs matrix, the films exhibited high transmittance, high haze, exceptional mechanical properties, and the ability to effectively shield 96.5% UVB and 69.3% UVA radiation. Most importantly, the inclusion of d-Limonene exhibited a remarkable enhancement in the inhibition zones against E. coli and S. aureus, and an outstanding 72.5% improvement in antioxidation properties. These outstanding film properties make the Cs/OCNF@d-Limonene coatings ideal as conformal films for fruit protection, which can effectively reduce the fruit water loss rate, delay ripening, prevent oxidation and microbial invasion, and significantly extend the shelf life of fruits. The well-designed coatings present a promising, cost-effective, and sustainable alternative to conventional plastic packaging materials for fruit protection.
