Abstract

The challenges of post-harvest losses in fruit includes inadequate infrastructure and storage facilities, leading to spoilage and reduced shelf life, impacting both farmer’s livelihoods and food security. The aim of the study is to extend the shelf life of strawberry using silver nanoparticles (Ag-NPs). The experiment was carried out using four treatments (T1-1000 ppm silver nitrate for 5 minutes, T2- 2000 ppm silver nitrate for 5 minutes, T3- 30 ppm silver nanoparticles for 5 minutes, T4- 60 ppm silver nanoparticles for 5 minutes) with three replications. Traits used for analysis are Total Soluble Solids, Total Sugars, Reducing sugars, Non -reducing sugars, Titratable acidity, Vitamin C, Physical hydrogen, Fruit weight, Fruit firmness and physiological loss in weight. The readings were recorded on 3rd, 6th and 9th day of storage after treatment. Correlation analysis was conducted between the biochemical and physiological parameters. The experimental results found that high significant and positive correlation was observed between Vitamin ‘C’ and Physiological Loss Weight (0.406*). Fruit firmness showed positive and high significant association with total soluble sugars (0.382*), total sugars (0.501**) and reducing sugars (0.390*). Interestingly, fruit weight had a significant correlation with reducing sugars (0.422*) and firmness (0.648**).

Conclusion

In the present study strawberry fruits treated with silver nanoparticles showed positive correlation with Total sugars, Total soluble solids, Reducing sugars, Fruit firmness, Titratable acidity, Physiological Loss of Weight and vitamin ‘C’ on 9th day of storage. Therefore, it is concluded that coating with silver nanoparticle enhances the quality parameters with increase in shelf life of strawberry.
