The HYFFI project


The first EU funded project that CyberColloids participated in was aimed at developing new, low molecular weight (LMW) agar and alginates for potential for use in health & wellness products; to screen them in vitro for beneficial effects on gut microflora and SCFA (short chain fatty acid) production and to validate selected candidates in vivo for prebiotic efficacy.


19 different LMW products were produced by CyberColloids and screened in vitro by the University of Reading, UK. 2 were chosen for in vivo evaluation at the University of Ulster, UK. CyberColloids participation in the project enabled the SME partners to develop new capability in the production of LMW products for use in the food, horticulture and animal feed sectors.
