SUMMARY:

The use of nanoprotein α-lactoalbumin (α-la) as a substitute for NaCl in the production of minas frescal cheese was tested in this work, to produce a cheese with less sodium and with the same technical-functional properties given the need to reduce the consumption of NaCl that causes damage to human health. In addition, nano α-la is a bioactive encapsulating agent, which can then make the Minas Frescal cheese a nutraceutical food. The synthesis of nano α-la showed a protein with a hydrodynamic radius of 191.10 ± 21.33 nm and PDI of 0.359 ± 0.059 via Dynamic Light Scattering (DLS) and MET indicates spherical nanostructures with a size of 16.98 ± 2 , 14 nm. The thermal analysis of the nano indicates a mass decay at 84 ºC by the TG and the DSC indicated an enthalpy of -253.2 J · g-1 for denaturation of the nanoprotein at 57.8 ºC. The encapsulation efficiency (EE) and the binding capacity (LC), respectively, 98.50 ± 0.28% EE and 74.32 ± 1.22% LC for quercetin and 69.36 ± 0.82% EE and 12.38 ± 0.15% LC for vitamin B2. The optimization and analysis of the influence of nano α-la on cheese carried out by a Rotational Experimental Design (DCCR) had as dependent variables physical-chemical parameters (pH, titratable acidity, soluble solids, and conductivity) and texture profile analysis (TPA), determining a methodology for the production of minas "frescal" cheese with 292 µL of nano α-la 2 mg · mL-1, 2.5 g of NaCl and 0.0 g of KCl for 500 ml of milk.
