4Protection is a Sacco line of lactic acid bacteria to protect products from the development of unwanted microorganisms. 4Protection cultures are composed of 100% natural lactic acid bacteria that help to maintain the structural and sensory properties of products throughout their shelf life.

Hard cheeses are products with a relatively low water content (around 35%) and a very intense flavour, derived from long ageing processes (beyond 6 months).

Sacco System has developed specific lines of live cultures for the natural protection of hard and extra-hard cheeses, including Emmental, pecorino, Gruyère, Parmesan, Grana Padano and many more.
