Tikhur (East Indian Arrowroot) (Curcuma angustifolia Roxb.): The Starchy Root of Versatile Nutrition
摘要
Curcuma angustifolia is part of the ginger family, Zingiberaceae, which also includes familiar spices like ginger and turmeric. It is native of Indian subcontinent. It has around 50 types and 1000 species and is distributed throughout central, southern, and eastern India, but most commonly reported from the Northeast and Western Coastal Plains and hills of India. Curcuma angustifolia is a relatively obscure yet significant source of starch. It is also known as white turmeric or narrow-leaved turmeric or East Indian arrow-root. Curcuma angustifolia is propagated via rhizomes, which serve as the main reservoir for its nutritional and medicinal properties. In Chhattisgarh, it is locally known as ‘tikhur’. Tribal people in Chhattisgarh, Orissa, and north-eastern India cultivate Curcuma angustifolia for starch. The rhizomes and starch of Curcuma angustifolia (Tikhur) possess medicinal properties, including acting as an appetizer, alleviating burning sensations and stomach discomfort, assisting in kidney stone removal, and providing relief for ulcer patients. It has been reported that Tikhur starch is a rich source of carbohydrates, lipids, proteins, essential nutrients, and minerals. When mixed with water or milk, the starch powder serves as a nourishing, filling meal, especially beneficial for newborns and growing children. Additionally, beverages containing Tikhur starch can act as a nutritious supplement alongside breast milk. It is consumed during fast and festive occasions. Consumption increases during summer season in the form of herbal drinks due to their cooling effect, which prevents body from heat strokes. The starch of Curcuma angustifolia is widely used in food production due to its excellent thickening, gelling, and water-retaining characteristics. The rhizome, easily digestible and highly valued in dietary use, has yet to be fully explored or utilized for industrial applications. Despite its potential, the starch of Curcuma angustifolia has not received significant attention in the food industry. This chapter deals with the nutritional, medicinal importance, and production potential of this crop.
