“…However, the range of the significantly decreased L * value for control from 0 to 10 days is 65.21 ± 0.75 to 34.69 ± 0.15 and for coated sample from 65.81 ± 0.75 to 52.23 ± 0.64, respectively. Also, decreasing in the lightness ( L * value) indicates the browning of cut apples (Monteiro Fritz et al, 2019 ; Morais et al, 2019 ). Moreover, decreasing in the redness ( a * value) suggests an increase in the hue values.…”

In recent years, the demand and market for minimally processed fruits are increasing worldwide. Fresh‐cut apples are extremely sensitive to environmental factors including oxygen, temperature, and microorganisms in resulting the browning of apples. Therefore, in this study, different concentration of blended edible‐coating solution was prepared using Aloe vera and carboxymethyl cellulose (1:1, 1:2, 2:1, 3:3, 3:2, 4:2, 2:4, 3:4, and 4:3, respectively). Lease particle size (101.74 ± 0.67 nm) of the coating solution was observed with 3% A. vera and 2% carboxymethyl cellulose (CMC). Afterward, the shelf life of the apples was evaluated for 10 days at refrigeration condition. Results showed that a significant difference was found in weight loss of coated (6.42%–10.26%) and uncoated apples (8.12%–15.32%) for 2–10 days. Moreover, the titrable acidity of the cut apples increased during the storage time. Rheological data emerged that the viscosity of the coating solution decreases with the increasing temperature from 0 to 50°C. Fourier transform infrared spectroscopy data confirmed the presence of hydroxyl group (–OH), C=O, C–O, and N–H banding in the A. vera, CMC, and blend‐coating solution. The blend solution indicated excellent antimicrobial efficiency. Total phenolic content of coated and uncoated apples at 0 day was 737.55 mg GAE kg−1 for uncoated and 717.88 mg GAE kg−1, respectively. Whereas, aerobic and psychrotrophic bacteria counts for edible coated apples significantly lower than control apples. For coated apples, aerobic and psychrotrophic bacteria counts were 1.59 ± 0.84 and 1.25 ± 0.49 log CFU g−1 were 4.26 ± 0.67 and 2.68 ± 0.22 log CFU g−1 at 10th day, respectively. Overall, it can be inferred that blend of A. vera and carboxymethyl cellulose could be used as a nontoxic potential anti‐browning and antimicrobial component for the enhancement of the shelf life and additional nutritional value of fresh‐cut apples.

“…The formulations that offer more advantages are the active coatings [ 153 ]. Several materials, such as CaCl 2 , CaCO 3 , and calcium pectate, have been reported to prevent fruit softening, postpone senescence, and increase shelf life [ 162 ]. Figure 9 shows a schematic picture of edible CMC/calcium salt coatings used to prevent fruit surface oxidation, softening, and senescence.…”

The increase in the population rate has increased the demand for safe and quality food products. However, the current agricultural system faces many challenges in producing vegetables and fruits. Indiscriminate use of pesticides and fertilizers, deficiency of water resources, short shelf life of products postharvest, and nontargeted delivery of agrochemicals are the main challenges. In this regard, carboxymethyl cellulose (CMC) is one of the most promising materials in the agriculture sector for minimizing these challenges due to its mechanical strength, viscosity, wide availability, and edibility properties. CMC also has high water absorbency; therefore, it can be used for water deficiency (as superabsorbent hydrogels). Due to the many hydroxyl groups on its surface, this substance has high efficacy in removing pollutants, such as pesticides and heavy metals. Enriching CMC coatings with additional substances, such as antimicrobial, antibrowning, antioxidant, and antisoftening materials, can provide further novel formulations with unique advantages. In addition, the encapsulation of bioactive materials or pesticides provides a targeted delivery system. This review presents a comprehensive overview of the use of CMC in agriculture and its applications for preserving fruit and vegetable quality, remediating agricultural pollution, preserving water sources, and encapsulating bioactive molecules for targeted delivery.

“…[70] Moreover, global fruit and vegetable trade has its own set challenges, such as, retaining the quality and freshness of fruits and vegetables travelling long distances, and ensuring safety and swift movement of fresh fruits and vegetables through the supply chain. [71] Application of edible coatings might therefore be considered as an interesting strategy to preserve the freshness and extend the shelf-life of fresh fruits and vegetables during long distance trading, thereby enhancing profitability and growth of fruit and vegetable trade sectors. Considering the significant share of international fruit and vegetable trade as well as the aforementioned challenges, the cost feasibility and industrial applicability of edible coating application on fresh fruits and vegetables will be discussed in this section.…”

As the world population is expected to rise to nearly eleven billion by 2050, a concomitant rise in the demand for fresh fruits and vegetables (FFV) is expected. FFV are highly perishable and constitute 20% of the global food wastage with nearly 30% of the losses occurring at the postharvest (PH) phase. This represents a challenge to ensure food and nutrition security for future generations. A proposed solution is the use of edible coatings incorporating natural ingredients that have the potential to reduce PH losses. Rising consumer demands for healthy, safe and sustainable food have translated to a greater acceptance of natural edible coatings. Edible coatings are hydrocolloid-based layers often applied to the surface of FFV to confer physical protection as well as extending shelf-life and consumer attraction. Although there has been extensive research on edible coatings, their widespread use has been limited due to a number of challenges such as a lack of standards and regulations, limited market research on consumer opinion and purchase intent, difficulties in scaling-up for industrial application and environmental sustainability concerns. This article attempts to shed light on the drivers fostering, as well as barriers impeding, commercial uptake of edible coatings in the FFV industry.
