“…Avocado membrane structure is made up of mainly cellulose and hemicellulose, as well as pectins; hydrolysis and depolymerization of these structures by enzymes such as polygalacturonase and pectin methylesterase results in fruit softening (Bower and Cutting, 1988). Dhalsamant et al (2017) reported that the use of modified atmosphere packaging with O 2 (2%) and CO 2 (10%) delayed ripening and softening in mango fruit. In this study, it could be argued that coating fruit with GA 15% + M, CMC 1% + M, and GA 10% + M resulted in a modified atmosphere with reduced O 2 and increased CO 2 levels, causing a reduction of enzymatic activities in coated avocados compared with uncoated avocados.…”

This study investigated the efficacy of edible gum arabic (GA) and carboxymethyl cellulose (CMC) containing moringa (M) leaf extract as postharvest treatments for maintaining organoleptic quality and controlling Colletotrichum gloeosporioides on ‘Maluma’ avocado fruit. For the quality study, after the fruit was dipped into the treatments: GA 10%, GA 15%, GA 10% + M, GA 15% + M, and CMC 1% + M and uncoated fruit served as control, the fruit were then stored at 5.5 °C [95% relative humidity (RH)] for 21 days, and moved to ambient conditions at 21 ± 1 °C (60% RH) for 7 days to simulate retail condition. Quality parameters that were evaluated include mass loss, firmness, and color changes (L*, a*, b*, respectively), and sensory quality attributes, such as taste, color, mouthfeel, odor, and overall acceptability. Fruit quality study results showed fruit coated with GA 15% + M and CMC 1% + M had lower mass loss (3.66%), retained firmness (62.37 N), and color changes [L* (30.85), a* (−2.33) and b* (7.14)] compared with other treatments. In this biofungicidal study on antimicrobial properties of extracts, treatments against fungi strains using an in vitro test were investigated, which showed treatments of moringa leaf extract, GA 10% + M, and GA 15% + M suppressed radial mycelial growth of C. gloeosporioides by 30%, 28%, and 33%, respectively. In conclusion, our study demonstrated that GA 15% + M and CMC 1% + M retained fruit firmness and lowered weight loss and suppressed mycelial growth of C. gloeosporioides on ‘Maluma’ avocado fruit. These edible coatings could therefore be an alternative organic postharvest coating treatment and could potentially be commercialized as a new organic biofungicide for the avocado fruit industry.

“…Film packaging with an modified atmosphere has been widely used in fruit and vegetable storage (Wilson et al, 2019). Modified atmosphere packaging maintains a balance between fruit respiration and the air permeability of packaging films, which forms a microenvironment with high CO 2 but low O 2 so that inhibits the metabolism of fruits and vegetables and retains freshness for extended shelf life (Dhalsamant et al, 2017;Chen et al, 2019). However, as the primary packaging materials, gas permeability of PE films is limited.…”

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.

“…Modified atmosphere packaging (MAP) is a novel technology that can control gas composition inside the package to maintain freshness and extend the shelf life of fruits and vegetables. − Highly respiring produce requires modification of the O 2 and CO 2 levels in packaging. Gas composition changes within the packaging film depend on various factors such as the weight of the produce, respiration rate, package size, and gas permeability of the film. − By controlling the gas composition, MAP effectively reduces the respiration rate and dehydration of fresh fruits and vegetables, thus retarding deterioration and extending the shelf life. − Plastic films with an oxygen transmission rate (OTR) of over 10,000 cm 3 /m 2 ·d can induce a desirable modified atmosphere within fresh produce packaging throughout the storage period …”

This study focused on improving the mechanical properties of the poly(butylene succinate) (PBS) film by incorporation of poly(butyrate adipate terephthalate) (PBAT). At 20 wt % PBAT, elongation in the transverse direction improved by 373% while maintaining high tensile strength (27 MPa) and Young's modulus (262 MPa). The PBS80/PBAT20 composite film exhibited optimized mechanical properties. The absorbance coefficient of microperforated film at 980/cm for the 80PBS/ 20PBAT mix, corresponding to the 10.2 μm CO 2 laser wavelength, was 65/cm, indicating high film capability to absorb energy from the CO 2 laser. The introduction of microholes enhanced the gas permeability of the PBS/PBAT film. As fluences increased from 187 to 370 J/cm 2 , there was a notable increase in microhole area in 80PBS/20PBAT film from 19,375 to 46,421 μm 2 . Concurrently, the gas transmission rate for a singular hole increased from 45 to 210 cm 3 /d for the oxygen transmission rate (OTR) and from 115 to 220 cm 3 /d for the CO 2 transmission rate (CO 2 TR). For mango packed in microperforated 80PBS/20PBAT films, the O 2 levels inside the package gradually dropped and remained at 14.2% in PBS80/PBAT20-MP1 (OTR ∼ 68,900 cm 3 /m 2 •d) and 16.7% in PBS80/PBAT20-MP2 (OTR ∼ 131,900 cm 3 /m 2 •d), while CO 2 content increased to 6% for PBS80/PBAT20-MP1 and 4% for PBS80/PBAT20-MP2 throughout 33 days. On day 2 of storage in the nonperforated package, O 2 content dropped to 2% while CO 2 content rose to 22%. Mango packed in the 80PBS/20PBAT film package exhibited an unsatisfactory freshness quality due to the detection of a fermentative odor on day 5 of the storage period. Total soluble solids, color, and weight loss of mango remained stable during storage in all microperforated films. Results demonstrated that the mango shelf life was significantly extended by 35 days using 80PBS/20PBAT-MP1. Laser perforation offered a practical method for improving gas transmission rates (OTR and CO 2 TR) of 80PBS/20PBAT film for mango packaging.
