THE PRODUCTION & VARIETIES OF TURMERIC

The botanical name of Turmeric is Curcuma longa. There are many varieties of Turmeric, the most important commercial spice crop in India, which is the largest producer, exporter and consumer of Turmeric. Other producers include Thailand, Central and Latin America and South East Asian countries. Around 133 species of Curcuma have been identified worldwide. The three feet plant produces both flower and a rhizome (a stem found underground).

The good quality rhizome is judged by its clean, smooth skin and uniform colours. Rhizome looks like ginger and comes as fingers, bulbs and splits. While fingers are secondary branches, bulbs and splits are cut halves before curing. Rhizome is processed into powder or oleoresin (Turmeric extracts).

Turmeric harvest happens 7 - 10 months after planting, depending on the soil. Rhizome bunches are carefully dug out, cleaned and then cured or processed or stored for planting later. Before drying, rhizomes are cured, wherein they are boiled until soft. Turmeric powder is made after peeling the skin of the tuber and drying it completely. After the production of Turmeric, during the processing stage, Turmeric usually loses its essential oils. Whole fingers of Turmeric are grinded fresh for best flavour.
