Objective
Ash is the inorganic residue remaining after incineration, often as part of the proximate analysis. This analytical method outlines a procedure to measure the ash content of farina and semolina. A sample is placed in a previously ignited, cooled, and tared porcelain crucible and then incinerated at 600°C for at least 2 hr. Crucibles are transferred and cooled in a desiccator, and the weight loss is used to determine the percentage of ash. Due to the hydroscopic nature of ash, cooling time and sample load in the desiccator should be strictly controlled.
