Application
- β-lactoglobulin stabilized nanemulsions--Formulation and process factors affecting droplet size and nanoemulsion stability.: This research explores the stabilization mechanisms of β-lactoglobulin in nanemulsions, with implications for pharmaceutical and food sciences, potentially utilizing substances like potassium phosphate monobasic for stability and pH control (Ali et al., 2016).
