Potential of cold plasma pretreatment for preserving biochemical attributes and ensuring the microbiological safety of saffron stigma.

Saffron, similar to numerous other agricultural commodities, is susceptible to microbial contamination during cultivation and postharvest handling. Cold plasma treatment has emerged as an effective method for microbial inactivation while preserving food quality. The aim of this research was to preserve the color integrity and minimize the presence of microorganisms in dried saffron stigma by implementing cold plasma pre-treatment.
