Abstract

Food preservative plays a very important role in food industry. Sodium Benzoate is one of the most frequently used chemical food preservative. The present work deals with the study of Resistivity (RL) of Sodium Benzoate. A low frequency Time Domain Reflectometry (TDR) unit was developed and used for the study. In the present work aqueous solution of preservative is prepared with freshly collected distilled water. Eleven different molar solution were kept at four different (25oC, 35oC, 45oC and 55oC) temperature. Computer controlled water bath unit was used to maintain the temperature. It had been found that Resistivity (RL) of Sodium Benzoate is inversely proportional to the temperature as well as molar concentration.
