Quantitative estimation of aflatoxin and pesticide residues from turmeric (curcuma longa) as obtained in the selected area of Chamarajanagara and Mysuru districts, Karnataka

Abstract

Chamarajanagar and Mysuru are the major turmeric (curcuma longa) cultivated districts in Karnataka state. The present study was carried out in the different villages such as Badanaguppe, Kariyanakatte, Doddarayapete, Jyothidowdanapura, and Hebbasuru villages of Chamarajanagar district and Nagawala, Kodi, Sannegowdacolony, Belikere and Yelwala villages of Mysore district, Karnataka. During the cultivation of turmeric the farmers are used the pesticides in each steps, for high yielding purpose. This study was revealed that to measure the amount of pesticides present in the final product. Aflatoxin is produced by the fungi aspergillusflavus and it having properties of nephrotoxic, teratogenic, carcinogenic, and immunosuppressive. It can be determined by the reliable method like HPLC (column symmetry C-18; 4.6X250 mm) used with detection by florescence (excitation 364 nm, emission 465 nm). Like that the organophosphors also determined by GC (column summery RTX-5; 30m) the level can be indicated in ppb and ppm respectively.
