The effect of freeze-drying and gamma irradiation at 0.5, 1, and 2 kGy on the physicochemical composition (moisture, fat, ash, mineral, and chlorophyll contents), microstructure, total phenolic content, and antioxidant capacity of stevia leaves was investigated in the present study. The results obtained indicated that freeze-drying and gamma irradiation treatments caused significant reduction ( p ≤ 0.05) of moisture and fat contents in comparison with those of commercial leaves, while ash content was not significantly affected. Mineral composition was analysed. Among the analysed elements, potassium and iron levels were higher in the freeze-dried and irradiated samples, respectively. The microstructure was analysed using a scanning electron microscope. Micrographs revealed that a higher porous size structure was obtained by freeze-drying, and degradation of cell wall structure was more clearly visualized by irradiation at 2 kGy. However, the main functional groups were stable as confirmed by Fourier transform infrared spectroscopy analysis. The effects on chlorophyll content, phenolic profile, and antioxidant properties were evaluated before and after ten months of storage. In terms of chlorophyll contents, the freeze-dried leaves exhibited the highest content. Chlorophylls a and b decreased when storage progressed for freeze-dried leaves as well as for gamma-irradiated leaves. Both preservation methods gave significant advantages in increasing the total phenolic content and DPPH scavenging activity. Moreover, a significant increase of bioactive compounds and antioxidant activity was observed as the gamma irradiation dose increased. In addition, the storage time increased the amounts of polyphenols and DPPH scavenging activity. After 10 months of storage, gamma-irradiated leaves had the highest total phenolic content as well as the DPPH scavenging activity followed by freeze-dried leaves. The results indicate that freeze-drying and gamma irradiation at the studied doses could be effective postharvest methods for preservation of stevia leaf quality.

“…Irradiation process can solve the difficulties in storage of wholesale and buyer pack supplies during market dispersal and stock maintenance. Some studies indicate that electron beam (EB) irradiation 11,12 and gamma ray (GR) irradiation [13][14][15][16] are effective treatments for microbial decontamination of plant materials. Locey and Guzinski 17 stated that consumer preference is influenced by the color of red pepper powder.…”

“…The sensory attributes also remained unchanged up to a dose of 7.5 kGy during the entire storage period of 18 months. Recently Ramathilaga et al (Ramathilaga & Murugesan, 2011) have shown that electron beam irradiation did not change sensory properties of chyavanaprash, an Ayurvedic poly herbal formulation. The data obtained from sensory analyses thus further supports the results of microbiological analyses on the acceptability of the herbal drug stored up to 18 months.…”

Shelf life extensionQuality control a b s t r a c t Amritamehari churnam (AC) is an antidiabetic polyherbal formulation constituting of four herbal medicinal plants namely Phyllanthus emblica, Salacia reticulata, Tinospora cordifolia andCurcuma longa. The feasibility of using gamma irradiation at doses between 2.5 and 10 kGy to reduce microbial load and enhance shelf life of this formulation was investigated. The irradiated and non-irradiated products were stored at room temperature (25e32 C and 50 e85% R.H., 1.5 years). Acceptability of the irradiated product was assessed based on sensory, microbial, physical and chemical attributes as well as their antioxidant status. A dose 7.5 kGy was sufficient to maintain microbial quality within acceptable limit up to 18 months of storage. No significant differences in sensory properties were observed between the non-irradiated and irradiated sample. The applied dose did not cause any significant qualitative and quantitative changes in the chemical constituents, antioxidant activities as well as physical properties when measured by EPR spectroscopy.
