Increasing the colour stability of potato flakes with FORTIUM® R-WS20 Liquid Natural Rosemary Extract

This study demonstrates how FORTIUM® R-WS20 Liquid, a natural rosemary extract, effectively stabilizes the colour of potato flakes during ambient storage. Untreated flakes faded within two months, while those treated with FORTIUM R-WS20 retained their yellow colour for at least six months. The study also shows a clear dose-response benefit, with 1200 ppm offering greater protection than 800 ppm.

You will learn:

  • Natural plant extract like rosemary extract can effectively preserve the visual quality of food products.
  • Shelf life extension is achievable without synthetic additives, supporting clean label goals.
  • Colour retention is critical for consumer appeal in dehydrated and processed foods.
  • Dose optimization matters—higher concentrations of FORTIUM R-WS20 Liquid deliver stronger protection.
