DSM has expanded its Dairy Safe cheese biopreservation portfolio with a new range of phage-robust culture rotations.

DSM has added four new culture rotations to the portfolio to offer a more robust system, which it claims will help manufacturers effectively manage bacteriophages (phages) and overcome spoilage issues in cheese.

Insufficient management of phages can lead to fermentation delays and production slow-down, which can contribute to increased food loss and have a detrimental impact on cheese flavour, yield and texture.

The cultures are used in a rotation system with several phage alternatives, which the company says ensures consistent quality and performance among all rotations, while also delivering acidification, flavour and assured bioprotection against late blowing and spoilage.

The cultures – which are suitable for all types of milk – protect cheeses without the need for preservatives, enabling manufacturers to meet clean label and sustainability demands.

Dairy Safe has been on the market for more than 30 years and joined DSM's cheese cultures portfolio of biopreservation solutions after it acquired CSK Food Enrichment in 2019.

Christian Hemmer, business manager of cheese at DSM, said: “The expansion of our high-quality cultures comes at a time when the industry is actively seeking phage alternatives to build a robust rotation system that ensures consistency of supply and consistent quality and performance among all rotations.

“Our cultures also help the dairy industry towards its sustainability goals by reducing waste through late blowing defects. The easy-to-use cultures – combined with DSM’s end-to-end expertise and “one-stop-shop” portfolio of solutions – mean our customers can produce delicious, high-quality cheese that meets diverse consumer preferences.”
