Purdue's Philip Nelson banked tomato harvests in sterile tanks

Philip Nelson grew up working at his family's tomato canning plant in Morristown, Indiana, where the operation lived and died by a few frantic weeks each year: tomatoes ripened on a schedule set by the weather, not by the factory, and everything the plant could turn into paste, sauce or juice had to be processed in that short window before the crop spoiled. The rest of the year, expensive canning equipment sat mostly idle.

The available fixes all pushed cost in the wrong direction: build enough processing and freezer capacity to handle the full harvest peak, and pay for that capacity to sit unused most of the year; or accept that some of the crop would spoil before it could be processed, and eat the loss.

Sterilized the bulk, half-finished crop and stored it in sealed tanks, so the harvest became inventory instead of spoilage, letting the plant run steadily year-round.

Sterilizing bulk product and all contact surfaces kills spoilage pathogens before storage.

Stored material stays sealed until needed, so timing shifts to inventory, not capacity.

Room-temp storage avoids costly refrigeration, making large-scale banking economical.

Scalable tanks and bags let harvests be stored near farms and shipped to factories anywhere.

When supply is bursty but demand is steady, bank the intermediate material, not the finished product.

The technology decoupled harvest timing from manufacturing timing at a scale nobody had previously needed: bulk aseptic tanks scaled to over a million gallons, and by the 2000s a Brazilian producer, Citrosuco, was shipping up to 8 million gallons of orange juice at a time across the Atlantic in aseptic tanks built into cargo-ship hulls.
