Anti-rancidity protection for traditional sausage products. An all-natural rosemary preservative for anti-rancidity protection of fresh traditional merguez and chipolatas sausages, VivOX 4 is an oil-soluble, water-dispersible product that can increase shelf life while keeping typical organoleptic characteristics and microbial stability. Merguez and chipolatas are fresh-type sausages made out of beef, pork, chicken and/or lamb. Due to high-fat content they are highly sensitive to oxidation and can rapidly undergo unwanted organoleptic changes, including rancidity. By adding the allergen-free preservative, the shelf-life of these sausages can be extended by 65-80% in comparison to unprotected sausages, while maintaining original taste and flavour components. The preservative outperforms gold standards for these types of sausage products, i.e. citric and ascorbic acid.
