The purpose of the present investigation was to investigate the applicability of BTTT to sesame oils obtained from different parts of India and thereby examine the influence of geographical variations on bellier turbidity temperature test (BTTT) and assessing the purity of sesame oil available in markets of India using (BTTT). In the present work, the sesame oils used for analysis, such as sesame cooking oil (21.9) (smc, Alfa green), sesame oil(20.7) (sm, Appu black),gingelly oil(20.9) (gg, Shakti) and sesame oil(19.9)(sm1, Kabira) exhibited BTT in the range of 19.9 to 21.9 0C. The result have demonstrated the reproducibility through the analyzed data. Hence It is observed that sesame oil fulfils BTTT values as per Regulation (Food Products and Standards) 2011 of Food Safety Standards and Act 2006. The standard mean error is in between 0.06-0.12 in case of BTT. The present research paper are evaluate and assessing the purity of edible cooking sesame oil of different brands obtained from different parts of India and thereby examine the influence of geographical variations on bellier turbidity temperature test (BTTT). The sesame oils used for analysis, such as sesame cooking oil (21.9) (smc, Alfa green), sesame oil(20.7) (sm, Appu black), gingelly oil(20.9) (gg, Shakti) and sesame oil(19.9)(sm1, Kabira). The evaluation has been carried out for the purity of sesame oils using BTTT as qualitative tool. The BTTT values are exhibited in the range of 19.9 to 21.90C. It is observed that all the sesame oils are to pass the BTTT values as per the specifications of sesame oils. In case of BTT, The standard mean error is in the range of 0.06-0.12.
