The postharvest life of the blueberry begins before harvest

Is it possible to predict, prior to harvest, how long the fruit will retain its quality?

• The Pre-Harvest Shelf-Life Score® proposes integrating crop data to estimate the commercial shelf-life potential of blueberries.

• This approach expands upon standard post-harvest checks and aims to better guide decision-making for each batch.

Analysis

Blueberry quality assessment does not begin when the fruit enters the packing house. By that stage, aspects of its future performance have already been determined in the field. The question is how to leverage this pre-harvest information to anticipate how the fruit will behave during storage and distribution.

This is the premise explored by Paula Del Valle in her article on the Pre-Harvest Shelf-Life Score®, published by My Blue Project. The proposal encourages looking beyond post-harvest checks such as firmness, size, Brix levels, dehydration, and decay and integrating pre-harvest variables into the assessment of each batch.

This concept is particularly relevant for a supply chain where fruit may reach the market looking perfect yet lack the ability to maintain its quality throughout the journey. A better understanding of the fruit's potential prior to harvest would allow for earlier risk assessment and the adjustment of management and marketing decisions.

From Assessment to Prediction

The Pre-Harvest Shelf-Life Score® proposes a shift in approach: using crop data to move beyond measuring current quality toward estimating its future evolution. The goal is not to replace post-harvest analysis, but to complement it with a broader understanding of the fruit's journey.

This perspective can also help explain why seemingly similar batches behave differently after harvest. By linking pre-harvest data with post-harvest outcomes, the supply chain can establish more precise criteria for planning management and determining commercial destinations.

This raises a question for the industry: if commercial shelf life begins to take shape before harvest, what field data should be systematically incorporated into decision-making? Paula Del Valle explores this topic in her article for My Blue Project.
