The natural sources like fruits and vegetables are observed to have a rich source of nutrients, ecofriendly pigments and antioxidant etc. Along with it the peels of these sources which are regarded as waste are exploring the current environmental aspects on various applications. These natural colorant are efficiently processed by a simple aqueous extraction method. The analysis showed that the beetroot has a good source of betacyanin pigments that are found to be a water – soluble compound. The sample were subjected to various ranges of temperature, pH and other optimization study. It was kept in various range of temperature (RT – 110⁰), varied length of heating time (1- 10 min) and different range of pH (2 – 9). This was then further used to analyze and checked for its best obtained betacyanin content for its appropriate extraction and application. The study also enhances about the stability of the pigments by its best determined method. The analysis shows the best findings with a optimal conditions and stability for its future analytical applications. The aim of the study is to provide a efficient traditionally obtained natural dye that has various environmental friendly pigments and of higher values.

Keywords : Natural Source, Eco- Friendly, Pigment, Betalain, Betacyanin, Beta- Vulgaris, Traditional Colorant.
