“…Among various alternative approaches, surfactant‐assisted extraction, e.g., microemulsion technique (MET), is a novel procedure, capable of fitting to green eco‐friendly food‐grade systems. It has already proven its high potential to extract and solubilize different nutraceuticals and pharmaceuticals (Abbasi & Radi, ; Abbasi & Scanlon, ; Amiri‐Rigi, Abbasi, & Scanlon, ; Jalali‐Jivan & Abbasi, ; Radi & Abbasi, ). Therefore, in the present study, this nanotechnological approach, using various surfactants and co‐surfactants, has been selected to examine its capability for extracting lutein from marigold petal powder (MPP).…”

In the present study, the capability of microemulsion technique, as a novel technique for synchronous extraction and solubilization of lipophilic compounds, on lutein extraction from marigold petals was investigated. Under the optimized sonication (amplitude 100%, 120 s, 25°C), the extraction efficiency increased (85%) using SDS:ethanol (1:2)‐based ME. Moreover, sonication led to smaller droplets (12–163 nm) with favorable thermodynamic stability. In addition, the developed MEs showed higher thermal and especially UV stability in comparison to organic solvent extracts which were fainted with first‐order kinetics. It was also found that co‐surfactant could be eliminated from formulation on the expense of the optimized sonication, was valuable output form industrial point of view. These findings revealed the high potential of ultrasound technique on the extraction and solubilization of lutein by ME technique which can be directly utilized in lutein‐enriched functional foods and beverages. Practical applications From applicability point of view, the solvent extracted compounds cannot be easily dissolved in food or pharmaceutical systems that are mostly hydrophilic. Therefore, microemulsions (MEs), as green and environmentally friendly food‐grade systems, due to their potential capability for simultaneous extraction and solubilization of carotenoids are of great interest. Therefore, the present study confirmed the practical ability of MEs in lutein extraction and protection. All in all, the developed lutein MEs with high lutein extraction capacity and superior lutein chemical stability against thermal treatment and especially UV radiation is an original finding which allows design of new functional foods and could be potentially useful for enriching foods, pharmaceuticals, nutraceuticals, and supplement formulation.

“…Over recent decades, the evolution of the microemulsion systems has demonstrated remarkable progress in several areas, especially food systems. Microemulsions comprise optically isotropic and monophasic systems that are prepared by blending two immiscible liquid phases in the presence of a primary surfactant and, frequently, a secondary surfactant (co‐surfactant) and co‐solvent . They have an average droplet size of 1–200 nm (likely < 100 nm) and are known to have high solubilizing capacity for both water‐ and oil‐soluble compounds as a result of the existence of nanostructures demonstrating diverse curvatures and characteristics within the same single‐phase system.…”

“…They are also more efficient as a result of a high selectivity and solubilisation capacity for desired molecules, an absent or ultralow interfacial tension, the use of safer solvents, a shorter process time, and a reliance on the same apparatus as conventional liquid–liquid extraction techniques. In addition, they demonstrate a reduced operating cost and are environmental friendly, as well as being easy to handle and scale up …”

The lycopene microemulsion showed satisfactory stability over a process where its monodispersity and nanosize could be of potential advantage to the food and related industries. Regarding the carcinogenicity of synthetic colourants, potential applications of the lycopene microemulsion include in soft drinks and minced meat, which would result in a better colour and well-documented health-promoting qualities. © 2017 Society of Chemical Industry.

Nowadays, solvent (hexane) based oil extraction is a widely used commercial technique and there are a number of environmental, economic, and health related concerns. Overcoming such serious issues is driving research to develop alternative safe methods. In the present study, a novel technique, using lecithin‐based microemulsion system, is developed for canola oil extraction. At first, pseudoternary phase diagrams of canola oil/lecithin/propanol/water microemulsions are constructed and the effect of temperature on microemulsion formation was evaluated. So that, (lecithin/propanol)/water microemulsion premixes ([2:1]50:50 and [2:3]80:20) are selected for optimization (temperature, exposure time, premix:canola seeds ratio, and agitation rate) of oil extraction from canola seeds using one factor at a time design. Based on “one factor at a time” design, the highest extraction yield (82.6% wt) achieved at 60 °C, 60 min, 6:1 premix:canola seeds ratio without agitation; the premix composition was (lecithin/propanol)/water (2:1)50:50. From quality point of views, the microemulsion‐based extracted oils has lower peroxide value, higher acidity, as well as low phosphorous and lecithin contents in comparison with hexane extracted one. This technique confirms its simultaneous extraction, recovery, and solubilization capabilities which can be used for oil extraction and food formulation. Practical Applications: For many decades, vegetable oils are commonly extracted by mechanical pressing or extraction with solvents such as hexane. Hexane, a highly volatile and flammable solvent which requires expensive equipment for safe operation, is classified as a hazardous air pollutant and occupational exposure to n‐hexane can cause neurological symptoms and other health defects. Overcoming these serious issues is driving research to develop alternative safe methods such as microemulsion technique. This study introduces a novel technique using lecithin‐based microemulsion systems for extraction of edible oils from oilseeds. This technique, as a low energy consuming method, has great potency for being used as a safe and green oil extraction technique which is the developing direction for not only the dominant oil resources but also nutrient lipids which can be easily dissolvable in aqueous food and pharmaceutical formulations. Accurate ratios of canola seeds, lecithin, 1‐propanol and water at a moderate temperature were used to create a nano‐size canola oil lecithin‐based microemulsion which was then simply demulsified at lower temperature in order to separate the extracted oil (see picture). This technique as a low energy consuming, straightforward and environmentally friendly method could be used for solublization and extraction of oil from various sources.
