Natural germ reduction
BIOSTERIL ® has been operating its germ-reduction facilities in Ritschenhausen, Germany, since 1994. By means of a vacuum-steam-vacuum process, germ counts in dried foodstuffs can be reduced by several factors of ten in a natural, gentle way. This enables also the processing of certified organically grown produce.
Reduction of total germ count to completely safe levels
Eradication of pathogenic germs
Elimination of mould and yeast
Eradication of insects, larvae and eggs
Elimination of trace aggravators
BIOSTERIL ® is the market leader in this field and has accumulated extensive experience that enables it to achieve optimal results while preserving the sensory properties of the produce. Each year, the company degerms several thousand tonnes of tea, seeds, herbs, spices, dried mushrooms and dried vegetables, as well as raw ingredients for the pharmaceutical industry. Thanks to pinpoint temperature and pressure parameters, we can degerm your goods in a tailor-made fashion that meets your every need.Contact usContact us
Pilot unit for pre-trial measurements and development
Our pilot unit is built around a small-scale autoclave which enables us to conduct degerming tests and always determine the ideal set of parameters for treating highly delicate, price-sensitive produce. As a result, we can offer our customers the highest degree of certainty and safety. We would be pleased to conduct a trial degerming run on your behalf and draw up the optimal treatment programme for your produce.
