| Abstract | The specific heat, thermal conductivity and thermal diffusivity of fish paste mixed with different percentages of cassava flour were determined experimentally. The variables were moisture content, sample temperature and bulk density. Chemical composition of the sample used like protein, moisture content, fat, ash and carbohydrate were also determined. The specific heat values of fish paste based on the method of mixtures were found to be dependent on both the temperature and moisture content of the sample. The generalized equations develop in terms of temperature and moisture content showed that effect of moisture content was more predominant. The specific heat of fish paste varied linearly with moisture content at any given temperature. Thermal conductivity values of fish paste determined with probe method increased linearly with an increase in either its moisture content and temperature at different levels of cassava flour added. The influence of moisture content on thermal conductivity values was more pronounced throughout the experimental range. Thermal diffusivity was determined by transient cooling using the approach of Baird and Gaffney (1976) and Fourier's analysis. Barid and Gaffeney suggested method yielded relatively lower magnitude of thermal diffusivity values with small standard error than Fourier's analysis. However, both method appeared to be satisfactory in general. |
