“…The use of supercritical fluid extraction (SFE) in industrial processes has been increasing, mainly due to the environmental and quality factors involved: it is a process free of toxic waste, does not require extracts postprocessing to solvent removal and does not cause thermal extracts degradation, allows the low temperatures use, and prevents oxidation reactions, due to the light and oxygen absence on extraction column. Furthermore, it is a flexible process due to the continuous adjustment possibility of the solvent solvation power and selectivity [123][124][125][126][127].…”

Carotenoid is a group of pigments naturally present in vegetal raw materials that have biological properties. These pigments have been used mainly in food, pharmaceutical, and cosmetic industries. Currently, the industrial production is executed through chemical synthesis, but natural alternatives of carotenoid production/attainment are in development. The carotenoid extraction occurs generally with vegetal oil and organic solvents, but supercritical technology is an alternative technique to the recovery of these compounds, presenting many advantages when compared to conventional process. Brazil has an ample diversity of vegetal sources inadequately investigated and, then, a major development of optimization and validation of carotenoid production/attainment methods is necessary, so that the benefits of these pigments can be delivered to the consumer.

“…Indeed, supercritical-fluid extraction (SFE) applied to the processing of natural products such as natural pigments, and aromas, has received a lot of attention in the past two decades. In the South America, it has found several applications mainly due to the rich biodiversity of this region [5].…”

“…Studies of natural products from plants have normally focused in composition and pharmacological properties of extracts. In the area of supercritical fluids, the amount of data related to the composition and functional properties of SFE extracts is indeed very large as demonstrated by recent reviews (Meireles 2003; Rosa and Meireles 2005b). Nonetheless, data for process scale‐up and for the estimation of the cost of manufacturing (COM) of extracts are still lacking.…”

In this work, the global yields, composition and antioxidant activity (AA) of extracts from lemon verbena (Aloysia triphylla) and mango (Mangifera indica) leaves obtained by different separation processes were determined. Lemon verbena extracts were obtained by supercritical fluid extraction (SFE), while mango leaf extracts were obtained by SFE, low-pressure solvent extraction (LPSE) and hydrodistillation. The extract's constituents were analyzed by thin-layer chromatography, gas chromatography/mass spectrometry and gas chromatography/flame ionization detector. The AA of the extracts was evaluated by the coupled reaction of b-carotene/linolenic acid. The cost of manufacturing (COM) was estimated for the SFE extracts. Higher global yields were obtained using SFE at 350 bar/45C (1.49%) for lemon verbena and LPSE (3.04%) for mango. The AAs of the extracts were larger than that of the b-carotene for both plants. The minimum values of COM were U.S.$26.96 and 52.45/kg of extract for lemon verbena and mango, respectively.
