3. After denaturation, ß- LG may represent the ideal substrate for proteases (hydrolyze proteins), because ample regions are unfolded and accessible for the enzyme. Enzymatic hydrolysis of whey proteins improves digestibility, functionality and reduces allergenic reactions. The data generated for the kinetics of heat-induced hydrolysis of ß-LG by STĂNCIUC et al. (2008) is presented in the Table. • Under which conditions you will obtain higher hydrolysis of whey protein, at pH 7.0 using a temperature of 80°C for 10 min or by using a pH 7.5 heated at 70°C for 10 min.

**Enzymatic Hydrolysis of β-Lactoglobulin (β-LG) in Whey Proteins** **Substrate Characteristics:** - After denaturation, β-LG, a whey protein, serves as a suitable substrate for proteases. The denatured form has unfolded regions, making them more accessible to enzymes. - Enzymatic hydrolysis enhances digestibility, functionality, and reduces allergenic reactions in whey proteins. **Research Findings:** - The table below shows data from STĂNCIUC et al. (2008) on the kinetics of heat-induced hydrolysis of β-LG. **Table: First Order Kinetics on β-LG Susceptibility to Enzymatic Hydrolysis** | Temperature (°C) | k (min) | |------------------|---------| | | pH 7 | pH 7.5 | | 65 | 0.084 | 0.017 | | 70 | 0.119 | 0.077 | | 75 | 0.138 | 0.170 | | 80 | 0.190 | 0.296 | | Ea (KJ/mol) | 61.8 | 161.1 | - **Explanation:** - *Temperature*: Indicates the heat applied during the process. - *k (min)*: Rate constant of hydrolysis at given temperatures and pH levels. - *Ea (KJ/mol)*: Activation energy required for the reaction at different pH levels. **Optimal Conditions:** - For higher hydrolysis of whey protein: - Use a pH of 7.0 at 80°C for 10 minutes. - Alternatively, use a pH of 7.5 at 70°C for 10 minutes.
