“…A similar result was reported by Kavitha et al, 2015, who studied the effect of gamma irradiation (0.25 to 1.0 kGy) on antioxidant. The study revealed that irradiation treatment induced a significant enhancement in flavonoid content and superoxide anion radical activity and DPPH radical activity.…”

The effects of electron beam irradiation (5, 10 and 15 kGy) on shelf-life and major plant metabolites of an Ayurvedic medicinal plant Desmodium gangeticum was evaluated. Its root possesses incredible medicinal effects; hence powdered root sample (choorna) was subjected to radiation processing and thereby shelf-life extension. The root sample was found to possess an appreciable amount of phenolic and flavonoid compounds. Processing with radiation did not produce prominent changes in the phenolic content of samples even after storage for up to 12 months. In contrast, Calcium content was increased significantly (p < 0.05) on radiation processing wit 5 kGy and 15 kGy. Microbial status revealed that the untreated sample was acceptable only up to 4 months. A dose-dependent reduction in the microbial count resulted in all the radiation processed samples. Treatment with doses of 10 kGy and 15 kGy reduced the colony count to nil immediately after irradiation. Irradiation with 15 kGy kept the sample completely sterilized up to 2 months of storage and was acceptable even 12th month of storage. GC-MS analyses identified compounds with pharmacological importance such as methyl palmitate, mome-inositol, Neophytadiene, etc. Although, a slight change in mineral composition and phytochemicals were observed it could effectively decontaminate the medicinal herb and increase the shelf-life with minimum loss of major metabolites compared to other conventional methods of processing.

“…Ber fruit powder has free radical (DPPH) capacity of 90.50% as shown in Table 1. These findings are in resemblance with Kavitha and Kuna (2014) who formulated ber RTS beverage. Likewise,ber juice vinegar was formed and due to its high antioxidant activity it was called as functional vinegar (Vithlani and Patel 2010).…”

Efforts were made to formulate an antioxidant rich, low sugarburfi. The burfi was enriched with different levels of ber fruit powder (5%, 10% and 15% w/w) and coconut sugar (28% w/w). Sensory scores revealed that burfi with 10% ber powder had highest overall acceptability. The optimizedber powderburfi was compared with market samples and control burfi and the physicochemical property, antioxidant activity and total phenolic content varied significantly(P<0.05). Addition of ber powder significantly(P<0.05) increased iron content, vitamin C content, antioxidant activity and total phenolic content of optimized burfi followed by the effect of coconut sugar incorporation. The addition of coconut sugar showed significant (P<0.05) decrease in total sugar content. From the study, it was concluded that the incorporation of berpowder and coconut sugar was a great success and will be helpful for developingother value added dairy confectioneries.

“…Figure 3 showed that the pineapple flesh antioxidant system in terms of ascorbic acid and total phenolic content was not affected by gamma irradiation. Several reports confirm that enhanced antioxidant defense combats the oxidative stress induced by abiotic stressors such as UV radiation (Li et al, 2010;Kumari, Singh, & Agrawal, 2010) and gamma irradiation (Kavitha et al, 2015). An increase in phenolic compound biosynthesis and accumulation frequently occurs in plant tissues as a reaction to biotic and abiotic stresses (Dixon & Paiva, 1995).…”

Gamma irradiation is used as a phytosanitary treatment for tropical fresh fruit from some producing countries. An experiment was carried out to study the effect of gamma irradiation and season of harvest on the quality ‘Pattavia’ pineapple fruit. Fruit harvested in the summer and the rainy cool (winter) seasons were exposed to gamma radiation at dose levels of 0 and 400–600 Gy from a 60 Cobalt source and the fruit stored at 13°C and 90% RH for up to 21 days. Gamma irradiation did not affect the ratio of TSS/TA, antioxidant content, or ascorbic acid concentration. However, gamma irradiation did delay color development and also induced internal browning over 50% of flesh discolored in fruit stored for 14 days, especially harvested winter fruit. Moreover, harvesting fruit in different seasons had a significant effect on fruit quality after harvest and during stimulated sea shipment storage. The result showed that gamma irradiation can be used as a phytosanitary treatment with minor changes in eating quality. However, the internal browning was greater if fruit were stored longer than 1 week at 13°C.
