Estimation of the Moisture Diffusivity and Activation Energy in Thin Layer Drying of Ginger Slices

In the present work, the effective moisture diffusivity and activation energy were calculated using an infinite series solution of Fick’s diffusion equation. The results showed that increasing drying temperature accelerated the drying process. All drying experiments had only falling rate period. The average effective moisture diffusivity values varied from 2.807x10 to 6.977x10m s over the tempe...

Effects of Drying and Blanching on the Retention of Bioactive Compounds in Ginger and Turmeric

Ginger and turmeric, members of the Zingiberaceae family, are widely used for their pungent and aromatic flavour in foods and also for their medicinal properties. Both crops are often grown by smallholders in mountain areas on rich former forest soils with no need for fertilizers and pesticides, fulfilling de facto the conditions of organic agriculture. They are consumed fresh or dried. Drying ...

Occurrence of ochratoxin A in black pepper, coriander, ginger and turmeric in India.

Ochratoxin A (OA) contamination of black pepper, coriander seeds, powdered ginger and turmeric powder was estimated using indirect competitive ELISA. Samples (1 g) were extracted with 0.5% potassium chloride (KCl) in 70% methanol (5 ml) and diluted subsequently to give two-fold to ten-fold step-wise dilutions in phosphate-buffered saline containing 0.05% Tween 20 and 0.2% bovine serum albumin (...

Drying of Ginger, Turmeric and Guduchi in solar-biomass hybrid drier

429 Zingiber officinale Rosc. (Ginger), Curcuma longa Linn. (Turmeric) and Tinospora cordifolia (Willd.) Miers. ex Hook. f. & Thoms. (Guduchi) are the important spices and herbs. Ginger and turmeric are widely grown in different regions of India and are commercially important edible spices. Guduchi, as a drug plant, has bulk demand in the market ranging from 300 to 500 tonnes of dry woody stems...
