Innovative post-harvest technologies are in demand to meet the requirements of farmers and agricultural industries to ensure global food security and to avoid food wastage, Edible coatings that can prevent food spoilage and/or enhance shelf life have taken on increasing importance, Aloe vera, known for its antioxidant and antimicrobial properties, has been proposed as an active ingredient that can be incorporated into the biodegradable film, nanocomposite films by solvent casting, transparent films , Aloe vera was confirmed in various spectroscopic studies, which clearly show reduction in light transmittance for the nanocomposite films containing Aloe vera. The contact angle study showed an increase in hydrophobicity initially. Maximum tensile strength was obtained with 0.25 ml of Aloe vera, the potential use of nanocomposite solution as edible films was demonstrated in green chillies, which showed lower weight loss after 3 days when compared with uncoated chillies. In the first phase of this study, chitosan/nanocellulose nanocomposites enriched with Aloe vera have been proposed as a potential edible food coating material, bio based antibacterial coatings, Edible films or coatings based on natural polymers or biopolymers cause no environmental issues, as they are biocompatible and obtained from agricultural and animal products like proteins, gums, lipids, etc.,these improve the quality of food by limiting the migration of moisture, lipids, flavors /aromas, and colors between food components, carrying active ingredients (e. g., antioxidants, antimicrobials, flavour), and improving the mechanical integrity or handling characteristics, Chitosan based films were produced by blending with biopolymers such as polysaccharides or proteins, by adopting solution-casting, layer-by- layer, extrusion, and other techniques, Nanocellulose has gained increasing interest for a wide range of applications in different fields of engineering due to its renewability, anisotropic nature, excellent mechanical properties, good biocompatibility, tailorable surface chemistry, and interesting optical properties, It is a natural nanoscale product, and it also possesses characteristics like special morphology and geometrical dimensions, crystallinity, high specific surface area, rheological properties, liquid crystalline behavior, alignment and orientation, mechanical reinforcement, barrier properties, surface chemical reactivity, biocompatibility, biodegradability, lack of toxicity, etc., Aloe vera extract is tasteless, odorless, and colorless, and, therefore, it can be used in edible coating as an additive, Aloe vera based coating was used for enhancement of storage life and quality maintenance of papaya fruits due to its antifungal activity, aloe vera Inner gel extract of Aloe vera was shown to be effective against Gram positive and Gram negative bacteria, Aloe vera gel was an effective coating material for peach fruits during cold storage period. The coating was effective against weight loss and colour change, Strawberries coated with banana starch-chitosan and Aloe vera gel showed decreased decay rates under commercial refrigerated conditions and shelf life was found to increase up to 15 days.
