A Study on Extraction of Plant Based Bio Colours

Authors: P.Vijetha, R. Venkata Nadh, K. Ramesh Naidu, T.Swapna Sundari

Most of the synthetic colours are carcinogenic. Many natural colours are thought to play- a significant role in preventing or delaying the onset of many diseases. Optimized conditions were arrived for the extraction of plant based biocolours based on the literature survey. In the present study, extraction of bixin from annatto seeds was carried out using ethyl acetate and ethanol. A pure bixin is obtained by precipitating from petroleum ether. A simple method for preparing butter colour from annatto seeds is tested using castor oil and groundnut seed oil. Lycopene was extracted from tomatoes using ethyl acetate as a solvent and further purified by successive recrystallisation from ethyl acetate and ethanol. A stable oleoresin of lycopene was prepared in soybean oil. Purity of extracted colours is established from spectral studies.
