Recent Advances in Postharvest Techniques and Technologies for Preserving the Fresh Quality of Pineapple (Ananas comosus) – A Review

Background: Pineapple (Ananas comosus) is a tropical fruit widely appreciated for its distinctive aroma and sweet flavor. It is highly demanded globally due to its nutritional value and health-promoting properties. Despite its importance, pineapple faces postharvest challenges such as rapid deterioration, susceptibility to physical damage, and microbial spoilage. Objectives: This review aims to provide a comprehensive overview of existing techniques and technologies used to preserve the postharvest quality of pineapples, focusing on their applications, effectiveness, and significance to the pineapple industry. Methods: The review examines fundamental studies related to various preservation methods, including controlled atmosphere storage, modified atmosphere packaging, edible coatings, and cold storage. These methods were evaluated based on their potential to prolong shelf life and maintain pineapple quality. Results: The analyzed techniques demonstrated effectiveness in maintaining fruit quality by reducing deterioration, microbial spoilage, and moisture loss. Controlled and modified atmosphere storage helped delay senescence, edible coatings provided a protective barrier, and cold storage slowed physiological degradation. Combining preservation strategies often resulted in enhanced postharvest performance. Conclusion: Implementing appropriate postharvest technologies is essential for maintaining pineapple quality, minimizing losses, and supporting sustainable production. Consolidating current knowledge highlights critical areas for future research and innovation, aiming to improve postharvest practices and ensure consistent supply of high-quality pineapples.
