An experiment was conducted to standardize the post harvest technology for Tinospora during the year 2006-07 at Medicinal Plants Unit, Horticultural College and Research Institute, TNAU, Coimbatore. The stems of 18 months old climbers were harvested and cut into pieces of different sizes (2.5, 5.0 and 7.5 cm) and subjected to sun drying in temperature ranging from 29 to 34°C during day time and...

Breadfruit (Artocarpus altilis) is a traditional staple crop grown for its starchy fruit throughout Oceania. This study therefore investigated the effect of maturity and different drying methods on some rheological and physicochemical properties of reconstituted breadfruit flour (Artocarpus altilis) (amala). Freshly harvested breadfruits (mature and immature) were washed in clean water to remov...

this study determined optimum conditions for drying pomegranate arils in a solar dryer. a cabinet solar dryer was used in active and mixed modes. the response surface method was employed with nine treatments (runs) and a control run (3 m/s air velocity and 2 cm in thickness) and five replications. the bryte cultivar was tested and samples were dried to approximately 10% moisture. drying time, v...

ABSTARCT: Solar drying is an integral part of rural life for various products, especially vegetable, fruits & spices which are produced in rural areas and have no scientific means of preserving such raw products. This paper is an attempt to review the solar drying process & solar dryers used for chilli drying worldwide which includes types of solar dryer, drying process & techno economical feas...

Investigations were carried out on quality changes in salted and dried horse mackerel (Megalaspis cordyla). Sun drying (T1) and mechanical drying (T2) process for fish cured with salt were selected for estimating their efficiency and effect during six months storage period. Sun dried fish showed mean value of moisture, protein, ash and fat as 27.83 %, 54.13 %, 12.95 %, 5.99 %, respectively, whi...

Orphanides A., Goulas V., Gekas V. (2013): Effect of drying method on the phenolic content and antioxidant capacity of spearmint. Czech J. Food Sci., 31: 509–513. The changes in total phenolics, hydroxycinammic acid derivatives, and antioxidant properties of spearmint after five drying treatments (convection oven drying, freeze-drying, microwave drying, and air drying with the sun exposure and ...

many parameters affect essential oil yield and chemical composition of aromatic plants. for obtaining the highest quantity and quality of essential oil, it is necessary to know the proper methods of drying and distillation. the aim of this research was to investigate the influence of drying and extraction methods on the yield and chemical composition of the essential oil of eucalyptus sargentii...

This study was done to determine the effects of different thermal drying methods (sun drying, microwave drying and hot air oven drying) on the total phenolic content (TPC), total anthocyanin content and the antioxidant properties of Vitex negundo (VN) tea. Significant decline (P < 0.05) in antioxidant properties of hot air oven drying shows that this method is not the best method to preserve an...

The effect of size reduction on the drying rate of cassava (Manihot sp.) and plantain (Musa paradisiacal) chips were analyzed comparatively through physical and statistical operations. In this study, duplicate cassava and plantain chips were used with varying thicknesses of 2mm, 4mm, 6mm and 8mm. The chips were subjected to natural sun drying with ambient temperature of 29C and artificial tray ...
