Advancements in Apple Storage: New Technologies in Controlled Atmosphere Systems

Biblioteca Horticultura has published a new technical article titled “Apple Storage: Advances in Controlled Atmospheres”, presenting the latest innovations in apple preservation through controlled atmosphere (CA) technology. Authored by Dr. Alicia Namesny, Manager of SPE3, the publishing house behind Poscosecha.com, Postharvest.biz, Tecnología Hortícola, Actual FruVeg and Biblioteca Horticultura, the study delves into key strategies such as Dynamic Controlled Atmosphere (DCA) and Ultra-Low Oxygen (ULO) Atmospheres, both essential technologies for extending fruit freshness and quality.

Key Developments in Controlled Atmosphere Storage

Since the pioneering studies of Kidd and West in the 1920s, CA storage has continuously evolved, integrating advanced methodologies such as 1-methylcyclopropene (1-MCP), which has proven effective in reducing postharvest losses and maintaining product quality year-round.

This article examines several critical factors influencing apple preservation, including:

• Comparison between regular cold storage and controlled atmosphere storage.

• Evaluation of alternative refrigerants for enhanced efficiency.

• Consumer perception of apples stored under controlled conditions.

• CA strategies for transportation and adjustments for DCA systems.

• Quality and firmness analysis of varieties like Red Delicious, Cosmic Crisp®, Jazz, Isadora, and Rubinstep.

• The impact of ethylene and climate change on the development of physiological disorders.

Storage in the Context of Climate Change

Throughout 2024, various scientific conferences have emphasized the urgency of refining apple preservation techniques, especially in light of climate change. Recent studies have reported an increase in the incidence of lenticel blotch pit and other physiological disorders, highlighting the need for more rigorous postharvest monitoring and control strategies.

An Essential Resource for the Horticultural Industry

This article serves as a key reference for producers, researchers, and industry professionals seeking to optimize storage strategies and improve overall fruit quality.

Additionally, it includes commercial insights on leading companies specializing in controlled atmosphere facilities and postharvest treatments for apples, featuring industry leaders such as Ilerfred, Isolcell and Janssen PMP, known for their innovative solutions in postharvest management.
