Abstract
.
Micronutrients
and nutraceuticals such as vitamins, carotenoids, polyunsaturated fatty acids
and polyphenols are classes of food ingredients that are essential for human
health and well-being. These compounds are rarely added purely to the targeted
food application but rather in encapsulated, solid, dry product forms with
added functionalities such as improved stability, bioavailability or handling.
This review presents some of the industrially most relevant particle
technologies, as well as emerging ones, for synthesis and formulation of
micronutrients and nutraceuticals. The influence of technological process
parameters on product particle physicochemical properties such as size,
morphology and structure are highlighted as well as their importance for
end-use applications.

of functional foods: A conjoint analysis with probiotics”. Food Quality and Preference, Vol. 28 nº 1 (2013) 348–355.
Abstract
.
The
current study, performed on a sample of 600 respondents responsible of
household food shopping, explored consumers evaluation of four attributes of
probiotics functional foods: base product (yoghurt, orange juice and biscuits),
health claim (generic, psychological and prevention), price (high, regular and
low) and brand (familiar and unfamiliar). Conjoint analysis ascertained that
consumers consider the base product as the most important attribute in
selecting a probiotic functional food and asses prevention claim as the most
valuable. In addition cluster analysis revealed that customer groups
significantly differ in their evaluation of perceived healthiness of functional
foods and in the importance attached to price and brand.
