rowing attempts are being made to rationally utilize systems for human

health improvement and disease prevention. In this context, this

contribution is part of our interest in use nano-encapsulation strategies to

construct nano-vehicles; which in turn will exert the controlled and targeted

delivery of nutraceuticals. A nutraceutical can be defined as the actual

substance that confers a health benefit. Our research group has carried out

the nano-ecapsulation of bioactive compounds as resveratrol (Res), folic

acid (FA), betanin (Bt) into different biocompatible matrices. We also studied

the microvesicle production (MV) by

Lactobacillus casei

BL23 involved in its

probiotic

activity.We

characterizes the interactions between β-lactoglobulin

(β-lg) and isolated 7S and 11S globulins obtained from defeated soy flour

and folic acid (FA) at different load ratio and their functional implications, in

terms of colloidal behaviour and digestibility. The biological activity of nano-

complexes loaded with FA was explored in terms of their capacity to enhance

the biomass formation of L. casei BL23. The results concerning to nano-

complexes inclusion in culturemedia showed higher bacterial growth. Bt loaded

in a nanovehicle of 11S quinoa seed protein was designed. At this respect, we

found that protein solubility was increased in the presence of Bt. 11S-Bt nano-

complexes showed a synergistic effect in terms of both, antiradical or reducing

power capacity in comparison to Bt as evaluated by to methods, 2,2 -azino-bis-

(3-ethylbenzothiazoline-6-sulfonate) (ABTS), and by ferric reducing antioxidant

power (FRAP). On the other hand, Res was included into nanoparticles of

chitosan, a mucoadhesive and positive charged polysaccharide. Bioactivity

of all these nanoencapsulated materials were evaluated by in-vitro assays

of different human culture cells lines. These nanoencapsulated materials

could have the potentiality to exert the bioactive protection and the controlled

delivery in food, pharmaceutical and nutraceutical products. MV could be used

as nanomachine controlling the host genes expression.

Biography

Oscar E Perez is a Professor at National Lanús University

(Buenos Aires) in the Department of Productive Development

andTechnology.Hehasbeentrained inthefieldofnanoparticles,

biopolymers and food colloids. He has expertise in nano and

microencapsulation of bioactive compound, i.e. bioactives

peptides, micronutrients, folic acid, insulin, growth factors. His

research group has started the study of nanovesicle production

generated by probiotic lactic acid bacteria, the purpose is

exerting the bio-nano-encapsulation of nucleic acids and

reporters overexpressed proteins, the so called inter-kingdom

communication. He is Author and Co-author of more than 50

scientific papers in recognized journals and book chapters. He

has also contributed over 120 communications in conferences.
