Advances in apple packaging: a review

Area of Science:

• Horticulture
• Food Science
• Agricultural Engineering

Background:

• Apples (Malus domestica) are a globally significant temperate fruit crop belonging to the Rosaceae family.
• As a climacteric fruit, apples undergo post-harvest metabolic changes, leading to susceptibility to spoilage and economic losses.
• Effective packaging is essential for preserving apple quality and extending shelf life during storage, distribution, and transport.

Purpose of the Study:

• To highlight the critical role of apple packaging in mitigating post-harvest losses.
• To review conventional and non-conventional packaging techniques used for apples.
• To emphasize the importance of packaging in maintaining apple quality throughout the supply chain.

Main Methods:

• Review of existing literature on apple packaging technologies.
• Categorization of packaging methods into conventional (e.g., wooden boxes, crates) and non-conventional (e.g., modified atmosphere packaging, active packaging, edible coatings).
• Analysis of the primary and secondary functions of packaging in the context of apple preservation.

Main Results:

• Packaging significantly protects apples from external damage and environmental factors.
• Conventional packaging methods provide basic containment, while advanced techniques offer enhanced quality preservation.
• Non-conventional methods like Modified Atmosphere Packaging (MAP) and active packaging show potential for extending shelf life.

Conclusions:

• The selection of appropriate apple packaging is vital for reducing post-harvest losses and ensuring market quality.
• Advanced packaging solutions offer improved protection and shelf-life extension compared to traditional methods.
• Continued research into innovative packaging is necessary to meet the demands of global apple distribution.
