EU approves Delvo Nis, extending shelf life of liquid egg products
External influences and inherent contaminants limit the shelf life of liquid egg products. The recent approval of DSM's Delvo Nis by EU authorities for use in liquid egg products, offers opportunities to extend the shelf life of these products.
Nisin is a natural preservative and has been used in the food industry for more than 50 years. Delvo Nis by DSM Food Specialties is a product formulation based on active Nisin. In liquid egg Delvo Nis will prevent the growth of food poisoning spore forming bacteria, like Listeria monocytogenes and Bacillus cereus, of which typically 1% survives the pasteurization treatment.
Refrigerated temperatures provide ideal growth conditions for these bacteria, which pose a threat later in the food chain. Delvo Nis can increase the safety of food processors’ products, delivering high quality and safe scrambled eggs, omelets or pancake mix to the end consumer. Moreover the use of Delvo Nis in egg applications can help food processors, allowing milder thermal treatments, improving textural properties and maintaining appropriate shelf life.
