Efficient Seaweed Preservation Method

VALUE PROPOSITION

Teagasc researchers have developed a novel clean two-step method to preserve freshly harvested seaweed, for an extended period, prior to further processing. This could provide additional value add opportunities in seaweed product development, while potentially significantly reducing drying and labour costs for harvesters.

OPPORTUNITY

This innovative cost effective solution to extend the shelf-life of freshly harvested seaweed, would benefit harvesters, seaweed processors and ultimately consumers. We are seeking seaweed harvesters as potential licensees to validate and commercialise this technology.

DEVELOPMENT STAGE

Efficacy proven at pilot field scale (10kg fresh seaweed) with industry engagement scaled up from lab scale trials

IP Status: Published EPO Patent -”Method of preserving seaweed” EP4268609 A1

ADVANTAGES

- 26 weeks shelf life extension for fresh seaweed
- This two-step method involves blanching and storage in a unique chemical-free preserving solution
- Alleviation of harvesters time pressures and expensive drying, by allowing storage of fresh stock immediately after harvesting
