Crates of freshly harvested produce in a dim packhouse

Agritech

A large share of what a farm grows never reaches a plate. Most of that loss happens after harvest, in the days between the field and the shelf, and it is a materials problem as much as a logistics one.

Edible coatings for shelf-life extension

NilTech’s agritech branch develops food-grade edible coatings applied to fruit and vegetables after harvest. The coating is a nano-scale layer that slows moisture loss and gas exchange — the two mechanisms behind most spoilage — while remaining easily washable and safe to eat if it is not removed.

Development has concentrated on berries and cucumbers: two categories with short windows, high waste and very different surface behaviour, which makes them a demanding pair to solve together.

Objectives

  • A coating that measurably extends shelf life across produce with different surface chemistry

  • Food-grade throughout, and removable with plain water

  • Application compatible with existing post-harvest handling, without a new processing step

  • No detectable effect on taste, texture or appearance

Achievements

  • Coating system developed and applied to berries in trials

  • Second surface chemistry validated on cucumbers

  • Washability established as a fixed design constraint, not an afterthought

  • Food-grade formulation maintained throughout development

  • Application method matched to existing packhouse handling

Next milestones

  • Shelf-life extension measured by category

  • Independent food-safety testing

  • Regulatory classification, market by market

  • Grower trials on berries and cucumbers

  • Cost-per-tonne modelling against current losses

  • First grower and packer partners

Programme

  • Disciplines: Nanotechnology, Advanced Materials

  • Stage: validated in trials, preparing for pilot deployment

  • Target categories: soft fruit, salad vegetables
