Post harvest handling of fruits Core Steps in Fruit Post-Harvest Handling • Harvesting & Maturity Assessment: • Fruits must be harvested at the proper maturity stage (physiological or horticultural maturity) using careful manual or mechanical techniques to prevent bruising, cuts, or punctures. • Pre-Cooling: • Removing "field heat" immediately after harvest slows down respiration, ethylene production, and microbial growth. • Common methods include room cooling, forced-air cooling, hydro-cooling, vacuum cooling, and package icing. • Cleaning and Washing: • Removing dust, latex, field soil, and residues using clean water or safe antimicrobial washes (such as chlorinated water or peracetic acid). • Sorting and Grading: • Eliminating damaged, diseased, or misshapen fruits (sorting), and categorizing the remaining produce by size, weight, color, and quality grade (grading). • Post-Harvest Treatments: • Waxing: Applying natural (carnauba, shellac) or synthetic coatings to reduce moisture loss (transpiration) and improve gloss. • Chemical / Heat Treatments: Using fungicide dips, hot-water treatments, or ethylene inhibitors (like 1-MCP) to control decay and manage ripening. • Packaging: • Packing fruits into corrugated fiberboard (CFB) boxes, plastic crates, or using modified atmosphere packaging (MAP) to provide physical protection and control humidity. • Storage and Transport: • Maintaining optimal temperature and high relative humidity (80–95%) in cold storage and refrigerated transport vehicles to preserve freshness.

To ensure optimal produce quality, harvest at the right maturity by assessing physiological readiness and handling gently to avoid damage. Protect quality during processing through consistent cooling, sorting, and grading, while wisely applying preservation methods. Finally, preserve freshness for market by using appropriate packaging, maintaining high humidity in storage, and ensuring refrigerated transport with careful temperature monitoring.
