Ultrasound assisted extraction (UAE) of bioactive compounds
Al-Dhabi et al. and d'Alessandro et al. ) used UAE for the extraction on phenolic compounds from waste spent coffee grounds and black chokeberry waste respectively and reported the optimized UAE parameters for the higher yield. d'Alessandro et al. ) proposed a mathematical model based on Peleg equation and suggested different optimum parameters
The extraction methods used had an effect on the antioxidant activities of the sunflower seed extracts, mainly for their concentration in TPC, which was highly increased in the UAE extracts. To our knowledge, there is little information about similar comparative studies to get info on high energy extraction techniques and their effects on the
Impact of ultrasound on oil yield and content of functional
The optimum extraction parameters for UAE were as follows: n-hexane as extracting solvent, average particle size 250 ± 12 µm, extraction time 2 h, solid-to-solvent ratio 1:12, ultrasound frequency 24 kHz and temperature 50°C. Furthermore, the chromatograph showed that sunflower oil extracted by the UAE was rich in α-Linolenic acid (ω-3).
Before the extraction of TPCs, sunflower seed cakes, partially hulled and unhulled, were milled separately in a laboratory grinder (Tube-mill 100 control, IKA, Staufen, Germany) for 30 s each and sieved. To remove the oil residue, the sunflower meals were defatted with n-hexane (1:10 w/v, meal/solvent) at room temperature for 6 h. Briefly, 50 g
Optimization Methods for the Extraction of Vegetable Oils: A
The 225 W microwave power, 15 mL/g solid/liquid ratio, and 20 min extraction time were the optimum conditions necessary to obtain a yield of 87.4% ± 0.44%. The results showed that maximum yields for UAE were obtained in half the time required for microwave assisted extraction (MAE).
Bilgin et al. [46] obtained scarlet sage (Salvia Coccinea) extract using homogenizer assisted extraction and UAE respectively. The findings indicated that UAE shortened the extraction time and reduced the solvent consumption. Fifth, the extracted bioactive components has high purity [47], [48]. In the case of less impurity, separation and
Optimization of Ultrasound-Assisted Extraction of Bioactive
In this study, Pelvetia canaliculata L. macroalga, collected from the Atlantic Portuguese coast, was used as a source of bioactive compounds, mostly antioxidants, to incorporate them in sunflower oil with the aim of increasing its biological value and oxidative stability. The lyophilized alga was added to the oil, and ultrasound-assisted extraction (UAE) was performed. Algae concentration and
A recent study by Senrayan and Venkatachalam compared UAE with traditional solvent extraction (SE) in an orbital shaker and Soxhlet extraction (SXE) for the extraction Kapok seed oil. The study revealed a 92.29% of oil recovery within 10 min using UAE, which is significantly shorter than SE and SXE that required 5.7 h and 8 h, respectively.
- What is Ultrasound assisted extraction (UAE)?
- Ultrasound assisted extraction (UAE) can extract bioactive components in very less time, at low temperature, with lesser energy and solvent requirement. UAE as a non-thermal extraction technique is better equipped to retain the functionality of the bioactive compounds.
- Why should we use UAE as a non-thermal extraction technique?
- UAE as a non-thermal extraction technique is better equipped to retain the functionality of the bioactive compounds. However, the variables associated with UAE such as frequency, power, duty cycle, temperature, time, solvent type, liquid-solid ratio needs to be understood and optimized for each by-product.
- Can UAE be used to extract bioactives from fruit & vegetable by-products?
- The use of UAE in combination with other non-thermal extraction method such as microwave assisted extraction, enzyme assisted extraction, pulsed electric field assisted extraction for the extraction of bioactives from fruit and vegetable by-products is limited and requires to be explored further.
- What is ultrasonic-assisted extraction (UAE)?
- Ultrasonic-assisted Extraction (UAE) is a rapid and effective extraction technique that uses ultrasound to generate rapid movement of solvents, resulting in a higher mass transfer speed as well as acceleration of extraction. Compared to other advanced extraction techniques, UAE is more economic, eco-friendly, and convenient (Teng et al., 2016).
