Interpretive Summary:

Technical Abstract: Apple fruit has become a staple fruit commodity in many markets worldwide, making year-round availability crucial to retail chains. Consequently, apple storage practices have become increasingly sophisticated to meet rising quality expectations of fresh taste and a blemish free appearance. Modern storage regimes reduce overall fruit metabolism and maintain the consistency of many traits associated with good quality. However, cold storage in both air and under hypoxic conditions can also provoke a variety of both internal and external browning disorders when genetic susceptibility and other mitigating factors are conducive. Current understanding of metabolic processes related to various storage related disorders highlights the complexity of the underlying genetic and metabolic interplay that provokes and governs their development. New –omics-based techniques such as untargeted metabolic and gene expression profiling have now been employed to determine metabolic components and pathways involved in processes leading up to and beyond disorder development. Results indicate the involvement of some metabolic players and reveal opportunities to exploit our improved understanding to develop risk assessment tools as well as optimize and/or target storage conditions to reduce disorder risk while retaining fresh fruit quality.
