Steam sterilization is a decontamination process that exposes spices to saturated steam under controlled pressure, temperature and time to reduce microbial loads, making product safe for EU food markets without the labelling obligations that irradiation carries.
In trade practice
Processors validate each product-specific cycle by demonstrating a defined log reduction in target organisms, typically using Salmonella as the reference pathogen. Buyers request a validation report and batch microbiological certificates covering total plate count, Enterobacteriaceae, yeasts and moulds. A common mistake is accepting a generic validation rather than one matched to the actual spice matrix and particle size. The process is assessed during BRC or FSSC 22000 audits.
In a specification
A purchase specification typically states the required post-treatment microbiological limits and demands a process validation report confirming the steam cycle parameters used for that product.
