2.3. Preparation of food model systems
Assays were performed in distilled water, classified as food simulant according to local food regulations (Mercosur Resolution No.30 of 1992). This solution simulates aqueous food having a pH higher than 5, such as chocolate milk.
2.4. Lipid peroxidation stability
Lipid peroxidation was followed by the thiobarbituric acid (TBA) method, as described before (Marsanasco et al., 2011).
