Cúrcuma: planta medicinal, condimentar e de outros usos potenciais

Abstract: A cúrcuma (Curcuma longa L.), espécie originária do sudeste asiático, é considerada uma preciosa especiaria. Com a proibição do uso de pigmentos sintéticos nos principais países da América do Norte e Europa, têm sido procuradas alternativas naturais. A cúrcuma, além de sua principal utilização como condimento, possui substâncias antioxidantes, antimicrobianas e corantes (curcumina) que lhe conferem possibilidade de emprego nas áreas de cosméticos, têxtil, medicinal e alimentício.

“…Turmeric oleoresin is the organic extract obtained from the turmeric rhizomes (Curcuma longa L.), a tropical plant native from southern Asia. The phenolic pigment called curcumin, which is a bright yellow dye very susceptible to light and unstable at high pH, is the major turmeric pigment (Cecilio Filho et al 2000). Turmeric oleoresin undergoes oxidative degradation: several of their pigments decompose upon exposure to oxygen; hydroxyl groups are converted to unstable ketones, which, in turn, decompose into colorless compounds of short chains (Kshirsagar et al 2009).…”

“…Commonly used as a spice and natural food dye, turmeric powder is obtained from C. longa rhizomes, which, after drying and processing, result in a bright yellow powder valued as a natural food dye. The use of natural dyes by the food industry has increased recently, in part due to laws restricting the use of artificial food colorants in many countries (Antunes and Araújo, 2000;Cecílio-Filho et al, 2000). Consequently, turmeric has become an important ingredient in a variety of industrialized products such as sauces, mustards, dry seasonings, baking mixes, processed cheese, dry soups, beverages, and confections (Sasikumar, 2005).…”
