and d-limonene were extracted from waste
orange and lemon peel by an innovative eco-friendly process using
only water as dispersing medium and microwaves as energy source. Both
bioproducts were characterized by diffuse reflectance infrared (DRIFT)
spectroscopy, and the pectin samples also by scanning electron microscopy
(SEM). For pectin and essential oils extracted from waste lemon peel,
the results obtained at laboratory and semi-industrial scales are
compared. The high yields obtained, the quality of the bioproducts
and the environmental viability of the process support forthcoming
commercialization of the technology.
