How much can we trust polysorbates as food protein stabilizers - The case of bovine casein

Polysorbates are widely used in food and cosmetic products and pharmaceuticals for emulsion stabilization, preventing surface absorption and as stabilizers against protein aggregation. But their impacts on the secondary structure and conformational stabilization of bovine casein, a typical intrinsically disordered protein (IDP), have not been fully addressed so far, which is crucial to evaluate the performance of polysorbates as stabilizer for...
