Determining the acid insoluble ash in food products is a critical process in the food industry.
It helps assess the quality and purity of food products by identifying the amount of inorganic, non-digestible material present.
Here are the five key steps typically followed to determine acid insoluble ash in food products.
1. Sample Preparation
The food sample is first ground into a fine powder.
This ensures uniform heating and complete combustion.
Any moisture present in the sample is dried to prevent spattering during the heating process.
2. Weighing the Sample
The powdered sample is weighed accurately.
Usually, the weight is between 1 to 10 grams.
This maintains consistency in the results and prevents contamination from the container or the surrounding environment.
3. Heating the Sample
The sample is placed in a crucible and heated in an ashing furnace.
The temperature is typically around 600°C (1112°F) in an oxygen-rich environment.
This process burns off all organic matter, leaving only the inorganic, mineral components.
4. Acid Treatment
After the sample has been completely ashed, it is treated with a strong acid.
Usually, hydrochloric or nitric acid is used.
This step helps dissolve the soluble ash components, leaving behind only the acid-insoluble ash.
5. Final Weighing and Calculation
The remaining acid-insoluble ash is then dried and weighed again.
The difference in weight before and after the acid treatment gives the weight of the acid-insoluble ash.
The percentage of acid-insoluble ash is calculated by dividing the weight of the acid-insoluble ash by the initial weight of the sample and multiplying by 100.
