Metabolite Changes during Postharvest Storage: Effects on Fruit Quality Traits.

Area of Science:

• Agricultural Science
• Biochemistry
• Food Science

Background:

• Postharvest storage of fruits leads to metabolic changes, impacting quality attributes like flavor and aroma.
• Current fruit industry practices focus on cold storage and controlled atmospheres, but underlying senescence mechanisms remain unclear.

Purpose of the Study:

• To provide an overview of metabolic changes during postharvest fruit storage.
• To highlight the role of metabolomic platforms in understanding fruit senescence and quality.
• To identify key metabolites influencing organoleptic and health-promoting traits.

Main Methods:

• Review of existing literature on postharvest fruit physiology and metabolic changes.
• Focus on metabolomic profiling of key compounds like volatiles, sugars, acids, polyphenols, and carotenoids.

Main Results:

• Metabolic shifts during storage significantly affect fruit quality, including flavor and aroma profiles.
• Metabolomics enables comprehensive profiling of metabolites crucial for fruit quality and health.
• Identification of specific metabolic pathways affected by senescence under storage conditions.

Conclusions:

• Metabolomic approaches are powerful tools for elucidating the biochemical basis of postharvest fruit senescence.
• Metabolic markers derived from metabolomics can inform chemical phenotyping, storage strategies, and marketing decisions.
