1. Article Details

Hot Water Treatment Enhances Quality and Storage Life of Sapota Fruit (Cv. ‘Cricket Ball’) During Cold Storage. This study investigated the influence of hot water treatment (HWT) on the postharvest quality and storage life of sapota cv. “Cricket Ball” during cold storage at 15 ± 1°C. Four temperature-time combinations (52°C for 5 min, 52°C for 10 min, 55°C for 5 min, and 55°C for 10 min) were evaluated and compared with untreated fruits. The researchers assessed physical, physiological, biochemical, and antioxidant-related parameters throughout storage. The results showed that HWT at 52°C for 5 minutes was the most effective treatment, reducing weight loss, decay incidence, respiration rate, ethylene production, and firmness loss while enhancing antioxidant compounds and extending shelf life up to 18 days.

2. Novelty

The novelty of this research lies in its comprehensive evaluation of hot water treatment effects on sapota fruit, particularly the “Cricket Ball” cultivar, which has received limited attention in postharvest studies. Unlike earlier studies that mainly focused on physical quality changes, this work simultaneously examined physiological responses, biochemical characteristics, antioxidant compounds, and consumer acceptability. The study also identified a specific optimum treatment (52°C for 5 minutes) and demonstrated its effects on delaying ripening and maintaining fruit quality. Additionally, the inclusion of regression analysis to explain quality variations adds a modern analytical dimension to the research.

3. Impact

The study has significant scientific, economic, and practical impact. Scientifically, it improves understanding of how thermal treatments influence fruit metabolism, ripening behavior, and antioxidant retention. Economically, extending the shelf life of sapota to 18 days can reduce postharvest losses, improve market distribution, and increase profitability for farmers, traders, and retailers. The findings also benefit consumers by preserving nutritional quality and maintaining desirable sensory characteristics during storage. Overall, the research provides valuable information for improving the postharvest management of highly perishable tropical fruits.

4. Originality

The originality of the study stems from its integrated approach to evaluating fruit quality, storage behavior, and functional compounds under different hot water treatment regimes. The research combines conventional postharvest measurements with antioxidant profiling and predictive statistical modeling, offering a more complete understanding of treatment effects. The focus on a commercially important sapota cultivar and the identification of a precise, non-chemical treatment strategy further enhance the originality of the work. The study moves beyond simple shelf-life evaluation by establishing relationships between physiological processes and fruit quality maintenance during storage.

5. Experimental Rigor

The study demonstrates strong experimental rigor through the evaluation of multiple hot water treatment combinations and comparison with untreated control fruits. A wide range of parameters, including physical, physiological, biochemical, and antioxidant attributes, were monitored during storage. Measurements such as weight loss, firmness, respiration rate, ethylene production, decay incidence, total soluble solids, sugars, phenols, flavonoids, ascorbic acid, and antioxidant capacity provided a comprehensive assessment of fruit quality. Furthermore, the application of multiple linear regression analysis strengthened the reliability of the findings by quantitatively explaining the relationships among storage quality variables.

6. Sustainability Impact

The research has notable sustainability implications because it proposes a non-chemical and environmentally friendly method for extending fruit shelf life. Hot water treatment reduces dependence on synthetic postharvest chemicals and fungicides, thereby minimizing chemical residues and environmental contamination. By reducing postharvest losses and decay, the technology contributes to improved food security and more efficient utilization of agricultural resources. The treatment also requires relatively simple equipment and low energy inputs, making it a sustainable option for fruit handling and storage systems.

7. Applicability

The findings have high practical applicability for farmers, packing houses, fruit processors, exporters, and cold storage operators. Hot water treatment at 52°C for 5 minutes is easy to implement, cost-effective, and compatible with existing postharvest operations. Since the treatment successfully maintained fruit quality and extended shelf life to 18 days, it can facilitate long-distance transportation and marketing of sapota fruits. The technology is particularly useful in tropical and subtropical regions where postharvest losses of sapota are a major challenge.

8. Significance and Future Scope

The study is significant because it provides a scientifically validated solution to one of the major constraints in sapota production—its short storage life. The results establish hot water treatment as an effective technology for maintaining quality, reducing spoilage, and enhancing nutritional value during storage. Future research can explore the underlying molecular and biochemical mechanisms responsible for the observed responses, evaluate the technology under commercial-scale conditions, and investigate its combination with other postharvest treatments such as edible coatings, modified atmosphere packaging, or controlled atmosphere storage. Such studies could further improve the storage potential and market value of sapota and other tropical fruits.
