Gamma irradiation effects on microbial and qualitative properties of rosehip (Rosa canina L.) fresh fruit during storage
Fruit of rosehip (Rosa canina L.) has high economic, medicinal, and nutritional values. Rosehip is rarely consumed fresh due to limitations of seasonality and short shelf life. They are usually processed, which affects the nutritional and sensory characteristics of rosehip products. Radiation processing along with storage at 4 °C is a way to increase safety and prolong fresh rosehip durability. Rosehip fruits were harvested at enough maturity stage, irradiated at doses of 0 (control), 0.5, 1, and 1.5 kGy, and stored at 25 and 4 °C for 60 days. Gamma irradiation at 1 kGy caused an increase in weight loss during storage for 60 days at 25 °C. Microbial counts, total phenolic contents (TPC), total anthocyanin contents (TAC), ascorbic acid contents (AAC), DPPH• scavenging activity, total colour difference (∆Eh), and sensory properties were acceptable in the sample irradiated at 1 kGy and preserved for 60 days at 4 °C. The amounts of acidity, pH, and total soluble solids (TSS) were not significantly different from the control. Gamma irradiation at 1 kGy and thereafter storage of the irradiated fruit at 4 °C are suggested as minimal processing and storage conditions of rosehip fresh fruit (RFF) for 60 days.
