“…Gumus () also reported that the antifungal activities of spice and herb extracts were increased by irradiation at low doses (1.2 kGy) but decreased by higher doses (3–5.1 kGy). Conversely, Yamaoki and Kimura () found very little degradation of curcuminoids at the dose sufficient for microbial decontamination in turmeric powder.…”

Thyme, rosemary, black pepper, and cumin were packaged in 100% N 2 (MAP) or air (AP) and gamma-irradiated at 0, 6, or 14 kGy. The changes in antioxidant and antimicrobial activities of their essential oils and methanol extracts were determined. Irradiation decreased the total phenolic content of AP samples (except thyme). Irradiation increased the 2,2-diphenyl-2-picrylhydrazyl radical scavenging activity in thyme extract and cumin essential oil in AP, but it decreased the activity in cumin extract (MAP). Ferric reducing antioxidant power was increased in rosemary (MAP) and thyme (MAP and AP) essential oils and rosemary (MAP and AP) and black pepper (AP) extracts, whereas it was decreased in the thyme extract (MAP) by irradiation. Irradiation increased the b-carotene-linoleic acid bleaching based antioxidant activity in essential oils of thyme (AP) and black pepper (MAP), but it decreased the activity in cumin extract (MAP). Irradiation increased antimicrobial activities of thyme and cumin essential oils. Practical applications Gamma-irradiation is frequently used in sterilization of herbs and spices, but it may affect some of their quality attributes. The irradiation-induced changes in the quality depend on atmosphere (especially on O 2 level) during the treatment and thus can be controlled by modified atmosphere packaging (MAP). The effects of the combination of gamma-irradiation and MAP on antioxidant and antimicrobial properties of thyme, rosemary, black pepper and cumin are evaluated. Irradiation had an enhancing effect on the antioxidant and antimicrobial properties of the samples in most cases and can be applied under O 2 -free modified atmospheres.

“…To date, a single study has employed e-beam technology for sterilizing turmeric, utilizing doses spanning from 5 to 30 kGy [ 29 ]. The authors investigated the impact of these doses on the elimination of specific bacteria, the extraction of turmeric components, and the radiolysis of curcuminoids utilizing the high-performance liquid chromatography (HPLC) method.…”

Turmeric, known for its curcuminoid-rich rhizome, particularly curcumin, exhibits notable antioxidant and antiviral properties. The likelihood of microbial contamination necessitates finding reliable techniques for subjecting the sample to radiation from this plant-based raw material. One alternative is to expose curcumin to radiation (e-beam), which was carried out as part of this research. Confirmation of the lack of curcumin decomposition was carried out using HPLC-DAD/MS techniques. Additionally, using the EPR technique, the generated free radicals were defined as radiation effects. Using a number of methods to assess the ability to scavenge free radicals (DPPH, ABTS, CUPRAC, and FRAP), a slight decrease in the activity of curcumin raw material was determined. The analysis of the characteristic bands in the FT-IR spectra allowed us to indicate changes in the phenolic OH groups as an effect of the presence of radicals formed.

“…Here, we aimed to study the application of ionizing radiation to crude drugs and crude drug preparations as a countermeasure against microorganism contamination [8,9]. Many studies on the chemical and microbial qualities of irradiated herbs or medicinal plants have been reported [10][11][12].…”

Pharmaceutical products that mix natural raw materials are subject to unavoidable contamination with microorganisms from the environment and animals. This study focused on the effect of radiation on the quality of primary packaged pills, which are crude drug products. The pills, which were sealed in a sack for primary packaging laminated with polyethylene terephthalate, polyethylene, and aluminum foil, were irradiated by gamma rays or electron beam (EB). The survival counts of bacteria were reduced to 103 CFU/g or less by 6 kGy of irradiation. The counts of the spore-forming bacteria Bacillus megaterium, B. cereus, and Brevibacillus brevis in the pills were reduced to not over 100 CFU/g after 10 kGy irradiation. Although some of the cinnamaldehyde in the pills was oxidized to cinnamic acid, the decomposition of swertiamarin, berberine, glycyrrhizin, and cinnamaldehyde in the pills after 10 kGy irradiation were within the analytical accuracy by high-performance liquid chromatography. Gamma-ray or EB treatment at the final production of crude drug preparations was within the permissible standard value for the non-aqueous preparations for oral administration, with no statistically significant change in the indicator ingredients of crude drugs.
