how to determine ash content
food ash content determination
A gravimetric method for the determination of ash was collaboratively studied in 14 laboratories. The food is ashed at 550 °C to constant weight and the ash is determined by weighing. Seven samples of various food commodities with estimated ash contents varying between low and high (0.07-8.0 g/100 g) were included in the study.
The ash content is a measure of the mineral content and other inorganic matter in biomass . using the average total solids content as determined by the LAP “Standard Method for the Determination of Total Solids in Biomass”. 100 Weight x % Total solids ODW = air dry sample. 3. 11.2. Calculate and record the percentage ash on an ODW basis.
