The present investigation, entitled “Studies on post-harvest application of chemicals and packaging materials on ripening and shelf-life of banana (Musa paradisiaca L.) cv. Grand Naine”, was conducted during 2024-2025 at the Processing Laboratory, Department of Fruit Science, Pt. K.L.S. College of Horticulture and Research Station, Rajnandgaon, Mahatma Gandhi Udyanikee Evam Vanikee Vishwavidyalaya, Durg (C.G.). The study revealed that the physico-chemical and sensory attributes of banana were significantly influenced by post-harvest treatments. Among the treatments, T₈ [CaCl₂ (5%) + Polyethylene bag (LDPE 200 gauge)] recorded the highest values for total soluble solids (21.65 ºBrix) and ascorbic acid (4.15 mg/100 g pulp), while the lowest acidity (0.52%) was observed under the same treatment. In terms of sensory evaluation, T₈ also received the highest scores for appearance (8.75), flavour (8.92) and taste (8.92). Thus, treatment T₈ proved superior in maintaining quality and extending shelf-life of banana up to 20 days after storage under ambient conditions.
