Abstract

The preliminary results show that microwave-generated low pressure air plasmas could be a very efficient method for the decontamination of spices since the population of a microorganism (Bacillus subtilis) commonly found in black pepper (Piper nigrum L.) was significantly reduced on test substrates in a very short period of time. Based on the experimental results, a laboratory apparatus was developed for the sterilisation of spices.
