BIOSTERIL® ­Steam sterilization

BIOSTERIL® has been operating germ reduction plants in Ritschenhausen, Thuringia, since 1994. Using the vacuum-steam-vacuum process, germ counts in dried food raw materials can be reduced by several orders of magnitude in a natural and gentle way. This also makes it possible to pasteurize organically grown products.
