Scientific Basis of the Lipid Oxidation Calculator
The Lipid Oxidation Calculator is grounded in the thiobarbituric acid reactive substances (TBARS) assay, a widely used method to measure Lipid Oxidation. The assay quantifies malondialdehyde (MDA), a secondary product of lipid peroxidation, by measuring the absorbance of the MDA-TBA complex at 532 nm. The concentration of MDA is calculated using the Beer-Lambert Law:
\( A = \epsilon \cdot c \cdot l \)
Where:
- \( A \) is the absorbance at 532 nm.
- \( \epsilon \) is the molar extinction coefficient (typically 156,000 M⁻¹ cm⁻¹ for MDA-TBA).
- \( c \) is the concentration of MDA (mol/L).
- \( l \) is the path length (cm).
Rearranging for concentration:
\( c = \frac{A}{\epsilon \cdot l} \)
The MDA concentration is then converted to µmol/kg of sample by accounting for the sample mass. The formula used is:
\( \text{MDA (µmol/kg)} = \frac{A \cdot 10^6}{\epsilon \cdot l \cdot \text{mass}} \)
This method is validated by peer-reviewed studies in food science and is widely used to assess oxidative stability in lipid-rich foods.
Applications in Real-World Scenarios
Lipid oxidation has significant implications across various domains:
