“…The extraction efficiency increased by increasing the percentage of ethanol up to 40% for Crithmum maritimum and between 40-80% for Salicornia europaea. Rostagno et al [36] and Li et al [37] argued that for UAE the presence of water, in an ethanol-water mixture, caused a reduction of solution viscosity and an increase of plant swelling, thus increasing the surface area for solute-solvent contact and mass transfer.…”

The aim of this work was to study the characteristics of the extracts from two halophytes, sea fennel (Crithmum maritimum L.) and marsh samphire (Salicornia europaea L.) that naturally grow on the Mediterranean coast, by using ultrasound-assisted extraction (UAE) and supercritical fluid extraction (SFE). Best conditions for UAE were found at temperature 50°C, 20 min extraction time, 1:30 ratio solid:solvent and 40% (v/v) ethanol concentration. For SFE best conditions were at 50°C and 300 bar pressures with 40% (v/v) ethanol concentration. Total extract yield, total phenolic content, total flavonoid content and antioxidant capacity of the extracts were measured. For both species the best results were obtained with UAE technique. Between the two halophytes, the C. maritimum extract was the richest one in antioxidant compounds (total phenol = 23.44 mg GAE s g dw -1); under the best conditions the S. europea extract allowed recording only 9.31 mg GAE s g dw -1 of total phenol.

“…The ultrasonic output power could be set to a desired level ranging from 0 to 100% of the nominal power by the amplitude controller. Ultrasonic output powers were determined calorimetrically and ranged from 10 to 100 W according to the method described by Li et al (2004). The ultrasound-assisted extraction used in this study was similar to that described by Zhao et al (2007) with slight modifications.…”

“…Another mechanical effect caused by ultrasound may also be the agitation of the solvent used for extraction, thus increasing the contact surface area between the solvent and targeted compounds by permitting greater penetration of solvent into the sample matrix. The ultrasonic-assisted extraction (UAE) also required shorter extraction times and reduced solvent consumption (Li et al, 2004;Mason et al, 2011;Nazir et al, 2009;Zhang et al, 2008). Whereas Hromadkova et al (1999) reported that, ultrasound-assisted extraction can be carried out at a lower temperature which can avoid thermal damage to the extracts and minimize the loss of bioactive compounds.…”

-The aim of this study was to optimize extracion of flaxseed oil process by ultrasonic treatment and determination of its effect on ω-3 fatty acid. The extraction of flaxseed oil was optimized by using different solvents like methanol, acetone, petroleum ether, ethanol, hexane and dichloromethane. The ultrasonication treatment was optimized with respect to amplitude (20-80 kHz), temperature (25-40 • C), sonication time (20-80 min) and solid to solvent ratio (1:5, 1:10 and 1:15) for extraction of flaxseed oil. The extracted oil was subjected to GC analysis to determine ω-3 fatty acid. The recovery of flaxseed oil was higher with hexane followed by dichloromethane. The ultrasonic treatment at frequency of 40 kHz, temperature of 30 • C, extraction time of 40 min and solid to solvent ratio: 1:10 gave best results for extraction. The ultrasonic assisted extraction improves the extraction yield by 11.5% with similar amount of solvent. The chromatograph showed that there were no significant effects on α-Linolenic acid (ω-3) by the ultrasonic assisted extraction. This will beneficial to the oil extractor to recover higher amount of oil from same amount of the raw materials.

“…Ultrasound-assisted extraction is an efficient way of extraction in food and pharmaceutical industry (Nascentes et al 2001;Rostagno et al 2003;Li et al 2004;Rodrigues and Pinto 2007;Zhang et al 2008;Zhu et al 2009). The enhancement of yield induced by ultrasound is attributed to the disruption of the cell walls and the enhancement on the mass transfer of the cell content to the solvent, allowing more intracellular product released by some mechanical effects and acoustic cavitation (Zhang et al 2008).…”

Physico-chemical properties of gelatin from bighead carp (Hypophthalmichthys nobilis) scales by ultrasound-assisted extraction

In this study, gelatin was extracted from bighead carp (Hypophthalmichthys nobilis) scales by water bath (WB) and ultrasound bath (UB) at 60°C for 1 h, 3 h and 5 h, named WB1, WB3, WB5, UB1, UB3 and UB5, respectively. The physicochemical properties of gelatin were investigated. The result indicated that gelatin extracted from bighead carp scales had a high protein content (84.15~91.85 %) with moisture (7.111 3.65 %), low ash content (0.31~0.97 %). All extracted gelatin contained α-and β-chains as the predominant components. Gelatin extracted by UB obtained much higher yield (30.94-46.67 %) than that of WB (19.15-36.39 %). More voids and less sheets of gelatin structure were observed, when the gelatin was extracted by UB for longer time. Gelatin of UB-assisted extraction normally exhibited lower gel strength and melting points than that of WB, which may be resulted from the protein degradation reflected by the FTIR spectra and higher free amino group content. However, there was no significant difference between WB1 and UB1. Therefore, the ultrasound assisted extraction in a short time was a promising method to enhance the yield and obtain gelatin with high quality.
