Ice cream is a delicious and wholesome nutritious frozen food made by freezing a pasteurized mix with agitation to incorporate air and ensure uniformity of consistency. In present investigation, ginger-a natural herb was used as a flavoring agent in ice cream. Ice cream mix was exposed to a temperature much lower than freezing temperature for freezing. Freezing rate and therefore the freezing time is the most fundamental properties during freezing phenomena. The present investigation was taken up to quantify the variations of thermal properties viz specific heat, thermal conductivity, enthalpy with various levels of flavoring material i.e. ginger juice. The formulae of the previous investigators were used either directly or with some modifications for calculations of various freezing and thermal properties. After statistical analysis it was revealed that changes in freezing properties were non-significant while changes in the thermal properties were significant.
