Study Notes

Fortification of Breakfast Cereals

Fortification includes essential minerals such as Calcium (Ca), Iron (Fe), and Zinc (Zn).
Considered important to enhance nutritional value in breakfast cereals.

Mineral Stability

Minerals, like ash, exhibit low volatility and do not decompose at high temperatures.
Certain food processing methods can lead to the loss of minerals.

Titration Method

Titration involves measuring the concentration of an analyte using a reagent that forms a complex with it.
The strength of the interaction between the analyte and the titrant surpasses that of the indicator and titrant interaction.
Ethylenediaminetetraacetic acid (EDTA) is commonly used as a titrant.

Ash Content and Mineral Analysis

Ash content refers to the inorganic residue remaining after complete combustion or oxidation of organic matter in food.
Mineral content measures specific inorganic components' quantities in food, which aids in quality assessment.

Health Considerations

Sodium (Na) intake is linked to hypertension, making monitoring important in dietary choices.
