Abstract
The present invention relates to nanoparticles for the encapsulation of compounds, the obtaining and uses thereof. The nanoparticles comprise a zein matrix and a basic amino acid. Said nanoparticles can encapsulate a water-soluble or fat-soluble biologically active compound. It is applicable in the food, pharmaceutical and cosmetic sectors and in the nanotechnology sector.
Claims22
A nanoparticle comprising a zein matrix and a basic amino acid.
A process for producing a nanoparticle comprising a zein matrix and a basic amino acid which comprises:
- a) preparing a hydroalcoholic solution containing a zein and a basic amino acid;
- and
- b) adding water to the solution of step a).
A process for producing a nanoparticle comprising a zein matrix and a basic amino acid and a fat-soluble biologically active compound which comprises:
- a) preparing a hydroalcoholic solution (i) containing a zein and a basic amino acid;
- b) preparing an alcoholic solution comprising a fat-soluble BAC and diluting it with water to obtain a hydroalcoholic solution (ii) comprising a fat-soluble BAC;
- c) mixing said hydroalcoholic solution (i) containing a zein and a basic amino acid with said hydroalcoholic solution (ii) comprising a fat-soluble BAC;
- and
- d) adding water to the mixture resulting from step c).
A process for producing a nanoparticle comprising a zein matrix and a basic amino acid and a water-soluble biologically active compound which comprises:
- a) preparing a hydroalcoholic solution (i) containing a zein and a basic amino acid;
- b) preparing an aqueous solution comprising a water-soluble BAC and, optionally, a second basic amino acid, and diluting it with an alcohol to obtain a hydroalcoholic solution (ii) comprising a water-soluble BAC and, optionally, a second basic amino acid;
- c) mixing said hydroalcoholic solution (i) containing a zein and a basic amino acid with said hydroalcoholic solution (ii) comprising a water-soluble BAC and, optionally, a second basic amino acid;
- d) optionally adding a surfactant to the mixture resulting from step c);
- and
- e) adding water to the mixture resulting from step c) or from step d).
