Novel, clean seaweed preservation method

TResearch Spring 2024

Technology

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

Value propositions

  • Twenty-six 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

 Development stage

  • Efficacy proven at pilot field scale (10kg fresh seaweed) with industry engagement — and scaled up from lab-scale trials
  • Published Patent filed at EPO – ”Method of preserving seaweed” EP4268609

Opportunity to engage

  • This innovative, cost-effective solution to extending the shelf-life of freshly harvested seaweed would benefit harvesters, seaweed processors and ultimately consumers
  • Teagasc is seeking engagement with seaweed harvesters as potential licensees to validate and commercialise this technology
