Objective
Ash is the inorganic residue remaining after incineration, often as part of the proximate analysis. This multistep analytical method outlines a procedure to determine the ash content of molasses, sugars, and syrups. A representative sample is placed in a previously ignited, cooled, and tared platinum crucible. The sample is dried at 100°C, olive oil is added, and the sample is incinerated at 525°C until white ash is obtained. The ash is moistened, redried, and re-ashed at 525°C to a constant weight. Crucible(s) are transferred and cooled in a desiccator and weighed. Due to the hydroscopic nature of ash, cooling time and sample load in the desiccator should be strictly controlled.
