Biodegradable Cellulose Film Prepared From Banana Pseudo-Stem Using an Ionic Liquid for Mango Preservation

Abstract

The excessive use and disposal of plastic packaging materials have drawn increasing concerns from the society because of the detrimental effect on environment and ecosystems. As the most widely used fruit packing material, polyethylene (PE) film is not suitable for long-term preservation of some tropical fruits, such as mangos, due to its inferior gas permeability. Cellulose based film can be made from renewable resources and is biodegradable and environmental-friendly, which makes it a promising alternative to PE as a packaging material. In this study, cellulose film synthesized from delignified banana stem fibers via an ionic liquid 1-Allyl-3-methylimidazolium chloride ([AMIm][Cl]) were evaluated as packing material for mangos preservation. The moisture vapor transmission rate and gas transmission rate of the synthesized cellulose film were 1,969.1 g/(m2⋅24 h) and 10,015.4 ml/(m2⋅24 h), respectively, which are significantly higher than those of commercial PE films. The high permeability is beneficial to the release of ethylene so that contribute to extend fruit ripening period. As a result, cellulose film packaging significantly decreased the disease and color indexes of mangos, while prolonged the storage and shelf life of marketable fruits. In addition, the cellulose film was decomposed in soils in 4 weeks, indicating an excellent biodegradability as compared to the PE plastic film.

Extraction, characterization, and fabrication of cellulose biopolymer sheets from Pistia stratiotes as a biodegradative coating material: an unique strategy for the conversion of invasive weeds into value-added products

“…Further their study reported that the moisture adsorption capacity of the plasticizers could be a key ingredient in determining the degradation rate of biopolymers (Reshmy et al, 2021). Similar pattern of biodegradation was reported with cellulose lms prepared from banana pseudo stem when subjected to weight loss analysis after soil burial method for a period of 4 weeks (Ai et al, 2021). Cellulose biodegradation was reported to produce harmless end products like methane, CO 2 and water, the methane produced can be harnessed and integrated for bioenergy generation using modern technologies (Sharma et al, 2020).…”

A method for the treatment of black tea waste: Converting it into liquid mulching film and solid mulching film

“…SMF lost 14.9% of its body weight on day 10 (Figure 8g) and the hue of the sample lightened as a result of the morphology of the buried sample. The weight loss rate of SMF was 24.2% in the following 30 days (Figure 8h), and due to microbial infection, the sample color further faded and brown spots formed on the surface 31 . At day 60 of degradation (Figure 8i), the surface of SMF had obvious voids and cracks.…”

Recent Advancements in Smart Biogenic Packaging: Reshaping the Future of the Food Packaging Industry

“…Numerous research studies have reported that using nanostructured cellulose fibers as a strengthening material in composite packaging can result in significant improvements in gas permeation properties, thermal stability, and biodegra- Furthermore, the hydrophilic inclination of the film, due to the presence of chitosan was overcome using silica, by tuning it to be hydrophobic, which is a desirable property in food packaging [20]. Compared to commercially available polyethylene, the cellulose-based film fabricated from delignified banana stem fibers by Ai et al [21] demonstrated higher gas and moisture permeability. The increased permeability aided ethylene release, thereby delaying the ripening of bananas and extending the storage period of mangoes.…”
