“…The application of A. vera as a coating agent prevents the degradation of chlorophyll and the accumulation of lycopene in the ripening stage. In addition, the A. vera coating act as a barrier to air and moisture, thus decreasing the respiration rate of fruit [63,64].…”

Aloe vera is widely used to manufacture medicinal products, cosmetics, and hair treatments. The polysaccharide components in A. vera gel can be used as ingredients for edible films or coatings. The edible film can also be applied to fresh fruits and vegetables using the coating principle. Tomatoes are one of the fruit commodities that can be maintained in terms of quality during storage using an edible coating. This study aims to determine the effect of an edible coating made from A. vera on tomatoes’ physical, chemical, and organoleptic properties during storage. The A. vera gel was prepared and used for coating the tomatoes, and the tomatoes were then stored for twelve days. The analysis was conducted every three days, and a comparison with non-coated tomatoes was performed for tomatoes’ physicochemical and organoleptic properties. The results show that the application of A. vera as a coating agent could prolong the shelf life of tomatoes, as described in the ability to decrease moisture content and weight loss. The coated tomatoes had lower titratable acidity value, pH, and total soluble solid contents than the non-coated tomatoes. From the organoleptic test, the non-coated tomatoes were preferred by the panelists for color, but the glossiness, skin appearance, and texture of the coated tomatoes were preferred. The coating process could maintain the hardness of tomatoes and prevent the production of phenolic compounds, flavonoids, and lycopene; thus, the antioxidant activity could be conserved.

“…A controlled atmosphere (CA) of 2 kPa O 2 + 5 kPa CO 2 at 6 • C significantly delayed scale yellowing, rot, and chlorophyll degradation and maintained fruit firmness and soluble solids, according to Ho P et al [24]. Scale yellowing was reported in pitaya harvested at eight ripening stages and stored at room temperature for 5 days; the reduction in chlorophyll content in scales was negatively correlated with a sharp increase in chlorophyllase, chlorophyll degradation, peroxidase (POD), and demagnesium chlorophyllase activities [31].…”

Highly prized for its unique taste and appearance, pitaya is a tasty, low-calorie fruit. It has a high-water content, a high metabolism, and a high susceptibility to pathogens, resulting in an irreversible process of tissue degeneration or quality degradation and eventual loss of commercial value, leading to economic loss. High quality fruits are a key guarantee for the healthy development of economic advantages. However, the understanding of postharvest conservation technology and the regulation of maturation, and senescence of pitaya are lacking. To better understand the means of postharvest storage of pitaya, extend the shelf life of pitaya fruit and prospect the postharvest storage technology, this paper analyzes and compares the postharvest quality changes of pitaya fruit, preservation technology, and senescence regulation mechanisms. This study provides research directions for the development of postharvest storage and preservation technology.

“…The chitosan-and κ-carrageenan-based composite coating was more effective in retaining the chlorophyll content and nutritional quality of dragon fruit when combined with GA 3 or MeJA pretreatment. This composite coating, combined with hot water treatment, controlled the diseases by regulating H 2 O 2 accumulation and antioxidant enzyme activities and maintained the overall quality of dragon fruit [66]. Moreover, fruit dehiscence during ripening is a crucial postharvest problem in "Chanthaburi II" durian, a new hybrid cultivar of Thailand.…”

Fruits, particularly tropical fruits, have a high moisture content, distinct morphological characteristics, and physiological changes, all of which contribute to their high rate of perishability. Nonetheless, their organoleptic and nutritional qualities make them one of the most important horticultural products. Fruit coating, which imitates natural packaging, is a postharvest solution that is practical and cost-effective for a variety of applications, including on-shelf display, transportation, and storage in support of the supply chain of fruits and vegetables. Gas and moisture permeability, microbiological resistance, and esthetic enhancement are the coating functions. Using modified materials and procedures, edible coatings for fresh and freshly cut fruits are currently being developed. Edible coatings infused with essential oils or volatiles may help to prevent disease resistance while also providing consumers with a fragrant preference. When considering how to advance fruit coating technology when agricultural wastes are the primary source of new coating materials, composite coatings, nanoparticles, encapsulation, and multiple-layer coatings all hold a great deal of promise. Future research may center on the optimal material for particular fruits during the logistics phase.
