Micro- and nanoencapsulation have generated great interest over the last
years in multiple fields. Particularly in the food industry, this technology
presents potential applications for the development of smart packaging
structures, as well as for the protection of sensitive ingredients and the
production of novel healthy foods. Therefore, in this thesis, the
development of different encapsulation structures of interest in the food
area was carried out. Specifically, capsules were obtained through
electrohydrodynamic processing, since this technology presents several
advantages over other well-established encapsulation technologies. For
instance, it does not require the use of high temperatures and
encapsulation structures from some biopolymers can be attained by using
aqueous solutions.
Initially, microencapsulation for smart packaging applications was
investigated. In this area novel heat management packaging structures
were obtained through the encapsulation of phase change materials
(PCMs) within different polymeric matrices. The morphology, thermal
properties, molecular organization and thermal energy storage ability of
these capsules were evaluated.
Afterwards, the encapsulation of bioactive ingredients for functional food
applications was studied. In this field, novel micro- and nanoencapsulation
structures were initially obtained through electrospraying from food
contact materials. Finally, a vitamin and an antioxidant were encapsulated
within different hydrocolloid matrices through electrospraying. Capsules
attained were characterized and compared to those obtained through
other encapsulation techniques. Moreover, stability of the encapsulated
bioactives was studied under adverse conditions. / Pérez Masiá, R. (2014). MICRO- AND NANOENCAPSULATION VIA ELECTRO-HYDRODYNAMIC PROCESSING OF INTEREST IN FOOD APPLICATIONS [Tesis doctoral].
