Amongst Rhododendron arboreum, Kilmora (Berberis asiatica), Ghengharu (Crataegus crenulata) and Galgal (Citrus pseudolimon), the highest (51.06 mg/100 ml) ascorbic acid was recorded in Galgal followed by Kilmora. The total antioxidants were found maximum (19.88 mM TE/l) in Rhododendron followed by Kilmora (14.12 mM TE/l). In all the treatments, TSS and acidity of the blended squashes was found to increase and decrease significantly faster at ambient (18-20oC) conditions than low (4oC) temperature. The highest (12.5 mg/100 ml) ascorbic acid was recorded in T9 (Galgal juice) and lowest (5.0 mg/100 ml) in T1, (Rhododendron juice) T5, (Kilmora juice) T7 (Ghengharu juice) and T8 (Ghengharu 15% + Galgal (5% + Ginger 5%), which was found to decrease significantly during storage both at ambient and low temperature. The reducing and total sugars in the blended squashes increased significantly during storage at both conditions. The total antioxidants were maximum (5.00 mM TE/l) in T1 (Rhododendron juice), which reduced to 4.65 and 4.84 mM TE/l after 6 months storage at ambient and low temperature respectively. Out of 10 treatments tried, the blended squashes (T2 Rhododendron 15% + Galgal 5% + ginger 5%, T4 Rhododendron 10% + Ghengharu 5% + Galgal 5% + ginger 5% and T3 Rhododendron 15% + Ghengharu 5% + Galgal 5%) prepared in combination with Rhododendron petal juice had an edge over other treatments (T1, T5, T6, T7, T8, T9, T10) in the overall quality. The prepared products had a shelf life of 6 months at ambient conditions, whereas at low temperature the products may be stored for one year without any microbial spoilage. The cost of production of the prepared products calculated was as low as 38.33 to 50.00% compared to the similar products (mango squash) available in the market. © 2015, Horticulture Society of India.

Sufficient evidences of the health benefits of wild edible fruits and their proven role in human nutrition are available. A number of wild but potentially commercialized fruits are existing in Himalayan regions of India such as red fruited ‘bayberry’ (Myrica esculenta Buch. Ham. ex D. Don) and ‘Yellow Himalayan Raspberry’ (Rubus ellipticus Smith), are amongst highly valued edible fruits. It would be advantageous to assess the antioxidant properties of these plants for possible use in the elaboration of functional foods or for consideration as potential sources of natural antioxidants. In this study, total carotenoids, flavanol, total flavonoids, O-dihydric phenol, total phenolics and total antioxidant capacity (measured by CUPRAC method) of underutilized fruit crops bayberry and yellow Himalayan raspberry based health beverages (ready-to-serve, RTS) stored at 5±2 °C for 10 weeks, were investigated. After the first two weeks in refrigerated storage, the RTSs showed an increase in total phenolics and total antioxidant capacity. However, at the end of the 10-week storage period, all RTSs exhibited a significant decline in total phenolics and total antioxidant capacity. However, total carotenoids appeared to be less affected during storage compared with the other antioxidants. © 2016, National Institute of Science Communication and Information Resources (NISCAIR).
