Abstract: A study was conducted to observe the effect of heat shrinkable films on shelf-life and quality of Assam Lemon [Citrus limon Burm.f.] stored under ambient conditions. Fully mature green Assam Lemon fruits collected from Orchard of the College of Horticulture & Forestry, Pasighat were subjected to three treatments viz. T₁(Individual Shrink wrapping), T₂(Shrink Wrapping in trays), T₃(Control treatment) and were stored in ambient condition (29-32^oC temperature with 55-78% relative humidity). Observations on PLW, TSS, titratable acidity, sensory quality, colour and marketability were recorded. Results revealed that heat shrinkable films influenced the quality parameters of Assam Lemon during storage. However, considering the physical and quality parameters, it was found that T₁(Individual Shrink wrapping) was the superior treatment having high marketable fruits, low physiological loss in weight (3.924%), better retention of colour, TSS(4.23^oBrix), titratable acidity(4.93%) with better sensory score as compared to T₂ (Shrink Wrapping in trays) and T₃ (Control treatment). The investigation revealed that Lemons could be stored up to 30-35 days when individually packed in heat shrinkable films with least PLW while maintaining the fruit quality at the same time under the ambient room temperature which can be recommended for Assam Lemon growers.
