“…[25][26][27][28][29][30][31][32][33][34][35][36][37][38] These conventional methods are based on the use of an ethanolic KOH solution under controlled conditions of time and temperature. The KOH concentrations ranged from 0.5 to 2 mol L -1 , while the incubation times ranged from 50 min to 18 h and the temperatures ranged from room temperature to 80 °C.…”

“…Furthermore, as stated in the literature, temperature is strongly associated with solvents properties, and an increase of temperature results in a decrease of both viscosity and surface tension, and induces an improvement in the mass transfer mechanism. 30,40 Thus, the selected conditions for the UAS were an ethanolic KOH solution concentration of 1 mol L -1 and an extraction time and temperature of 15 min and 70 °C, respectively.…”

“…30,33,34 Extraction efficiency enhancement by ultrasound has been attributed to the formation of microcavities that promote the rupture of cell walls, leading to an increase in mass transfer between the solid and liquid phases. 33,34 Therefore, the application of ultrasonic radiation in the saponification step can be an alternative to improve the conventional saponification methods, i.e., increasing the extraction efficiency and decreasing the saponification time.…”

“…28,29 Alternatively, methods that use less toxic reagents, e.g., hexane and ethanol, and extraction techniques, such as ultrasoundassisted extraction (UAE), have been employed to obtain lipid extracts. 30,31 The saponification step has been carried out based on the use of an ethanolic KOH solution under controlled conditions of time and temperature. In the related literature, several variations of the saponification step, such as different KOH concentrations, temperatures and incubation times can be found.…”

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...

“…Therefore, MAE has been widely applied to the extraction of various ingredients from different matrices (Liu et al 2012;Hadi et al 2015;Ramezani et al 2015). Over recent years, response surface methodology (RSM) has been extensively used to develop, improve, and optimize extractions of the chemical substances (Liu et al 2013;Habibi et al 2013;Lee et al 2014;Sarfarazi et al 2015;Barizao et al 2015). The prime advantage of RSM is the ability to use statistical modeling and analysis to simulate the extraction process, determine significant variables, and estimate optimal extraction conditions, to give the maximal yield of target responses.…”

A novel method for protein extraction from sweet almonds with aqueous polyethylene glycol (PEG) as solvent and recovery from the extraction solution was developed. The extraction yields of different solvents, such as sodium hydroxide, sodium chloride, PEG 200, PEG 400, and PEG 600 aqueous solutions, were investigated and PEG 200 showed the highest extraction efficiency. The PEG-based microwave-assisted extraction (MAE) parameters were then optimized using response surface methodology. Under optimum condition, PEG 200 concentration of 25 % (w/w), liquid to solid ratio of 22 mL g −1 , microwave power of 120 W, extraction temperature of 45°C, and extraction time of 4 min, the average extraction yield was 93.75 ± 3.15 %. Subsequently, the almond protein was recovered from the extraction solution containing PEG with an isoelectric point-ethanol synergy precipitation protocol. The combined technique integrated the speed of isoelectric point precipitation with the completeness of alcohol precipitation. The recovery of almond protein was 98.81 % with a time of 3-5 min. The proposed PEG-based MAE and synergy precipitation protocol provide a rapid and effective method for almond protein extraction and recovery and have the potential to be used for other plant proteins.

Emerging evidence has suggested that nutraceutical ingredients like pomegranate seed oil (PSO) possesses health‐promoting effects in cell and animal models. However, these health benefits (anticancer, antioxidant, anti‐inflammatory, anti‐diabetic, and so on) are limited by low physicochemical stability, slow intestinal absorption, and rapid metabolism of PSO. In order to overcome these drawbacks, some carriers viz., nanoemulsion, encapsulation, and nanoparticles are developed recently. This paper assesses the chemical compositions and physicochemical properties of PSO, as well as biological activities and possible mechanisms. It also discusses the formulation of PSO for improved stability and health‐promoting activities. Practical Applications: This review highlights the prospects of PSO formulation. The relevance of this study is that the stability and biological properties of PSO could be enhanced through nanocarriers. A formulated PSO has a potential use in nutraceutical, functional foods, pharmaceutical and cosmetic industries. PSO, a source of various nutrients and antioxidants with immense benefits to human health is incorporated into nanocarriers such as microencapsulation, nanoemulsion and nanoparticle. This improved the health‐promoting benefits of the oil.
