Ash Content Determination: A cleaned flat bottom flask silica disc was held for about one minute. It was then transferred to a dessicator to cool down and then weighed. 50cm3 of the ginger sample was taken into the dish and the total weight was obtained. The silica dish and the sample were heated gently on a bursen burner in a fumed cupboard until the smoke ceased. It was then transferred to a muffled furnace heated to about 500°C. The temperature was maintained for about 4hours to ensure that the whole carbon was burnt away. The furnace was switched off and silica dish removed, covered immediately and placed inside a dessicator to cool and then weighed.
