ABSTRACT:
The invention relates to a process for preparing an anti-freeze peptide and to the peptides obtained from bacteria from an aqueous low-temperature environment, such asMarinomonas proteaand aPseudomonasspecies. These anti-freeze peptides can suitably be incorporated in frozen food products such as frozen vegetables and frozen confectionery such as ice-cream.
