Response of post-harvest dipping on shelf-life and quality of guava (Psidium guajava L.) fruits under cold storage


Author(s): N Nasima, V Swaminathan, J Rajangam and K Venkatesan

Abstract: The present study was carried out to examine the effectiveness of post-harvest treatments on storability, physical and biochemical changes in guava (Lucknow-49) fruits at cold storage. Freshly harvested guava fruits were dipped for 5 minutes with, calcium chloride (1.0%), calcium nitrate (1.0 and 2.0%), Benzyl adenine 50ppm and these combinations along with control. Dipped fruits were kept in plastic crates under cold storage (8±2ºC and 90-95% RH) and evaluated different time intervals for various quality attributes. Among these, T4 - Ca(NO₃)₂ 2.0% treatment was found to be superior in extending the shelf life (28.33 days) as it showed lowest physiological loss in weight (8.56%), retained greater firmness (16.96 pound force), total Soluble Solids (8.19ºBrix), maintain titrable acidity (0.47%), total sugars (7.10%) followed by Benzyl adenine 50 ppm compared to all other treatments. However, Ca (NO₃)₂ 2.0% treated fruits exhibited longer shelf life and better maintenance in fruit quality during cold storage.
