“…The synergetic effect of both technologies again ensured by Sa ´nchez et al ( 2019) as the yield of canola oil increased when seeds are pretreated with microwaves followed by ultrasound extraction. In another study, around 85.23% of tiger nut (Cyperus esculentus L.) oil was extracted using UAME in combination with aqueous enzymatic extraction using cellulase, pectinase and hemicellulose at dosage of 1/1/1, (w/w/w) (Hu et al 2020).…”

“…As the oil industry is always looking forward to advanced extraction techniques with high efficiency, low cost, fewer impurities, and sustainable development, UAE for edible oil is a better solution. As the newest trend, ultrasound coupled with both microwave and enzymatic aqueous extraction of cherry and tiger nut seed oil has given oil recovery greater than 80% with superior oil quality than soxhelt extraction (Hu et al 2019a, b;Hu et al 2020). The results ensure the effect of ultrasonication hybrid with other technologies is more significant, even to replace solvents with an aqueous medium for oil extraction.…”

“…In a more advanced situation, ultrasound can be combined with other technologies like microwave, enzymatic and supercritical fluid extractions to be used directly in the process or could be used as a pre-treatment process. These hybrid techniques are useful in increasing the extraction efficiency of oil (Hu et al 2020;Goula et al 2018;Liu et al 2020).…”

A review on application of ultrasound and ultrasound assisted technology for seed oil extraction

Oil has extensively been extracted from oil-bearing crops and traded globally as a major food commodity. There is always a huge demand from the fats and oils industries to increase oil yield because of profitability benefits. If extraction is conducted under mild operating conditions to preserve and improve the oil quality, then it would be an added value. Ultrasound that works on the cavitational action helps to fulfil the gap. Ultrasound is gaining tremendous interest as an alternative to replace the current conventional extractions approach because of its multiple benefits. Cavitation generated by ultrasound eases the release of oil from cell matrices, thereby allowing the extraction to be carried out under mild processing conditions. The effect enhances the oil yield whilst preserving the quality of the oil. In ultrasound, green solvents can be used to replace toxic organic solvents. Recent up-to-date approaches utilised a combination of ultrasound with enzyme, microwave and supercritical technology to further enhance the oil extraction. This review highlights a comprehensive work of the impact of ultrasound and ultrasound in combination with other technologies on oil extraction, which emphasises the extraction yield and physicochemical properties of the oil, such as fatty acid composition, oxidative stability with the retention of the lipophilic phytochemicals and iodine, saponification values and colour parameters. Understanding of ultrasonication techniques for oil extraction served to be essential and useful information for the fats and oils scientists from academia and industries to explore the possibility of employing a sustainable and mild approaches for extracting oil from various crops.

“…The oil yield by SE can reach 29.85 g/100 g dried powder. However, the time consumed and the use of organic solvent has limited its application due to safety and environmental concern [ 19 ]. ME is a relative safe oil extraction method, however, the oil yield of ME method is relatively low (19.94 g/100 g) [ 21 ].…”

The tiger nut is the tuber of Cyperus esculentus L., which is a high-quality wholesome crop that contains lipids, protein, starch, fiber, vitamins, minerals and bioactive factors. This article systematically reviewed the nutritional composition of tiger nuts; the processing methods for extracting oil, starch and other edible components; the physiochemical and functional characteristics; as well as their applications in food industry. Different extraction methods can affect functional and nutritional properties to a certain extent. At present, mechanical compression, alkaline methods and alkali extraction–acid precipitation are the most suitable methods for the production of its oil, starch and protein in the food industry, respectively. Based on traditional extraction methods, combination of innovative techniques aimed at yield and physiochemical characteristics is essential for the comprehensive utilization of nutrients. In addition, tiger nut has the radical scavenging ability, in vitro inhibition of lipid peroxidation, anti-inflammatory and anti-apoptotic effects and displays medical properties. It has been made to milk, snacks, beverages and gluten-free bread. Despite their ancient use for food and feed and the many years of intense research, tiger nuts and their components still deserve further exploitation on the functional properties, modifications and intensive processing to make them suitable for industrial production.

“…Several studies have been reported regarding the evaluation of AEE in obtaining oils from various seeds such as tiger nut (Cyperus esculentus L.) [59], sacha inchi (Plukenetia volubilis L.) [60], Jatropha curcas [61], Jicaro [62], pomegranate [63], castor oil [64], Pinus pumila [25], Moringa oleifera [65], Pumpkin (Cucurbita pepo) [50], sunflower [66], soybean [67], almond [49], etc. Although the enzymatic oil extraction has been widely explored, in the reported studies, different oil yields are observed for each seed; this is due to the fact that the composition of the cell wall of the seed, which is quite heterogeneous, is different for each seed, so different enzymes and conditions are necessary in each case.…”

Aqueous Extraction of Seed Oil from Mamey Sapote (Pouteria sapota) after Viscozyme L Treatment

et al. 2021

In this study, aqueous enzymatic extraction (AEE) was evaluated during the process of obtaining oil from mamey sapote seed (OMSS). Viscozyme L enzyme complex was used at pH 4 and 50 °C during the optimization of the extraction process by central composite design and response surface methodology. Optimal conditions were: 3.5% (w/w) of enzyme (regarding the seed weight), 5.5 h of incubation time, 235 rpm of agitation rate, and 1:3.5 of solid-to-liquid ratio. These conditions enabled us to obtain an OMSS yield of 66%. No statistically significant differences were found in the fatty acid profile and physicochemical properties, such as the acid and iodine values and the percentage of free fatty acids, between the oil obtained by AEE or by the conventional solvent extraction (SE). However, the oxidative stability of the oil obtained by AEE (11 h) was higher than that obtained by SE (9.33 h), therefore, AEE, in addition to being an environmentally friendly method, produces a superior quality oil in terms of oxidative stability. Finally, the high oil content in mamey sapote seed, and the high percentage of oleic acid (around 50% of the total fatty acid) found in this oil, make it a useful edible vegetable oil.
