Food industry is increasingly interested in replacing conventional processes of plant extraction, as well as microbial inactivation, by alternative, greener and cheaper techniques. In many cases, chemical extraction processes are hindered by several drawbacks such as the use of chemical solvents, which is associated with many health and environmental issues. Furthermore, the use of high temperatures to improve and/or accelerate the processes, which may affect and degrade the thermolabile compounds, is usually required. Among the most promising techniques that could be competitive to the current extraction methods of molecules from plant matrices and microbial inactivation of food products, ultrasound assisted supercritical fluid extraction has taken great interest. This non-exhaustive review, covering the last 20 years, gives a critical commentary on the main published results using this emerging technology. Promising prospects opened up by new applications are described, without omitting the main limitations still to be overcome for a harmonious industrial development of these technologies.

An ultrasound-assisted saponification (UAS) method for the determination of phytosterols (campesterol, β-sitosterol and stigmasterol) in passion fruit seed oil, followed by gas chromatography with flame ionization detection, was developed and validated. Under the optimum conditions, good linearity with correlation coefficients higher than 0.99 was obtained for all analytes. The recoveries for the proposed approach were between 103 and 107%, the limits of quantification were between 70 and 180 μg kg -1 and the precision values expressed in terms of relative standard deviations (RSD) were lower than 19%. The developed method was successfully applied to the analysis of passion fruit seed oil samples from different species, including yellow passion fruit, sweet granadilla and sweet passion fruit. In all species of analyzed passion fruit seed oils, β-sitosterol was found with the highest abundance, ranging from 0.90 ± 0.02 to 1.60 ± 0.01 mg g -1 of oil, followed by stigmasterol (0.70 ± 0.01 to 1.40 ± 0.12 mg g -1 of oil) and campesterol (0.10 ± 0.01 to 0.30 ± 0.06 mg g -1 of oil). Furthermore, the developed method proved to be a time-saving and efficient analytical procedure for the determination of phytosterols in oil samples.Keywords: Passiflora species, campesterol, β-sitosterol, stigmasterol IntroductionPassiflora species are cultivated throughout the world in tropical areas.1-3 Passiflora edulis f. flavicarpa (yellow passion fruit), Passiflora alata (sweet passion fruit), Passiflora ligularis (sweet granadilla) and Passiflora edulis Sims (purple passion fruit) are species widely cultivated for their edible fruits. [4][5][6] Yellow passion fruit is the species most known and appreciated due to its organoleptic properties, such as an intense flavor and slight acidity. The pulp is destined for in natura consumption, but is predominantly used in juice production. 2,4 Furthermore, the pulp is known to be rich in bioactive compounds, such as carotenoids, phenolic compounds and vitamins A, C and D. 2,7 The large-scale production of passion fruit juice generates tons of by-products (peel and seeds) that are important raw materials in the food and cosmetic industries. 8 Recently, several studies have described that passion fruit peel is a source of fiber, predominantly pectin, which provides it with a range of potential applications as a stabilizer, emulsifier and as a thickening and gelling agent for the preparation of food products, e.g., functional beverages, mayonnaise and ice cream toppings. [8][9][10][11][12] In addition, it has been reported that passion fruit peel presents antioxidant activity and phenolic compounds. 5,13,14 Alternatively, passion fruit seeds are described as a rich source of lipids, proteins, minerals and fibers.14-16 Several studies have reported that passion fruit seeds contain about 30% oil, with linoleic, oleic and palmitic acids as the main fatty acids.14,15,17 Furthermore, as well as the peel, passion fruit seed oil has been described as a potential source of bioactive compounds, such as p...
