Food Safety
Killing of Microorganisms in Herbs
Safe steam sterilization for the highest food quality
The elimination of microorganisms in herbs is a crucial process in modern food production. Dried herbs are natural products and can become contaminated with microorganisms during cultivation, harvesting, drying, and transport. These include salmonella, enterobacteria, yeasts, and molds.
Imtech-Steri AG offers specialized solutions for the microbiological reduction of herbs -based on validated steam sterilization processes. The aim is to guarantee the highest food safety without impairing the sensitive aromatic properties of the herbs.
Why Is It Necessary?
Herbs are often used raw or only minimally processed in food products -for example, in spice mixes, ready meals, sauces, or marinades. Any existing microbial contamination can multiply further in the final product and poses a significant risk to both consumers and manufacturers.
The targeted killing of microorganisms in herbs serves:
Ensuring consumer safety by eliminating pathogens
Compliance with national and international food regulations
Meeting microbiological specifications for market access
Extending shelf life of the final product
Maintaining brand reputation and avoiding costly recalls
Steam Batch Sterilization
An effective method particularly suitable for dry products such as herbs, spices, seeds, or other plant ingredients.
Products are loaded into the sterilization chamber
Air is removed through a deep vacuum
Saturated steam is introduced at precisely controlled temperature
Steam penetrates the product achieving effective germ reduction
Rapid drying restores the original moisture content
Preservation of Aroma, Color and Structure
Herbs are characterized by complex essential oils, delicate aromatic compounds, and natural color pigments. The steam sterilization processes used by Imtech-Steri ensure an optimal balance between microbiological safety and product quality. Precise control of process parameters largely preserves the characteristic flavor of the herbs.
Validation and Documentation
In regulated markets, not only the killing of microorganisms is crucial, but also their verifiable documentation. Imtech-Steri supports customers with comprehensive validation packages.
