The ultrasound-assisted aqueous extraction of rice bran oil
We investigated ultrasound-assisted aqueous extraction of oil rice bran. • The yield at ultrasound assisted aqueous extraction was close to hexane. • Yields were highest at 25 °C and 70 min of ultrasound process. • The oil extracted by aqueous process had a lower content of free fatty acid.
In addition, this work studies the enhancement of aqueous enzymatic extraction of pomegranate seed oil by ultrasound probe. It was found that only 10 min in water are needed to recover oil with a yield of 18.15 g oil/100 g dry seeds, a value similar to or higher than those of the conventional procedures. Thus, the use of ultrasounds increased
The ultrasound-assisted aqueous extraction of rice bran oil.
With regard to quality, the oil extracted by ultrasound-assisted aqueous process had a lower content of free fatty acid and lower color imparting components than the hexane-extracted oil. Also, effect of parboiling of paddy on hexane and ultrasound-assisted aqueous extraction was studied. Both extraction methods gives higher percentage of oil
The study aimed to optimise the ultrasound-assisted aqueous extraction of oil, β-carotene and lycopene from powdered microwave-dried gac arils. Ultrasound power, extraction time, powder particle size and the ratio of water to gac powder during the extraction, the centrifugal force used to recover the extracted components were investigated
The ultrasound-assisted aqueous extraction of rice bran oil
The results showed that the yield of rice bran oil at ultrasound-assisted aqueous extraction was close to the yield of oil extracted by hexane Soxhlet extraction. This result implied that the

The ultrasound-assisted aqueous extraction of rice bran oil.
Moreover, extraction yields were compared to ultrasound-assisted aqueous extraction and Soxhlet extraction. The results showed that the yield of rice bran oil at ultrasound-assisted aqueous extraction was close to the yield of oil extracted by hexane Soxhlet extraction. This result implied that the yield of rice bran oil was significantly
The edibility and quality of edible oil are influenced by the level of free fatty acids. This study provides an optimization of low free fatty acids virgin avocado oil using ultrasound‐assisted aqueous method. Low free fatty acid virgin avocado oil is useful in developing a diverse array of functional foods, food supplements and health care
Ultrasound-assisted aqueous enzymatic extraction of oil
the ultrasound-assisted aqueous enzymatic extraction of oil from perilla seeds. The aim of the present study was to develop an efficient and environmental friendly method for the extraction of perilla seed oil. The effect of ultrasonic pretreatment and types of enzyme on oil
Almost, quantitative extraction of oil from watermelon kernels was achieved when the enzyme treatment with proteases was applied to the previously ultrasound-irradiated material (Sui et al., 2011; Liu et al., 2011b) or to microwave-dried material subjected to ultrasound-assisted aqueous extraction of oil, β-carotene, and lycopene from gac aril (Kha et al., 2015).
