Comparisons between conventional, ultrasound-assisted and microwave-assisted methods for extraction of anthraquinones from Heterophyllaea pustulata Hook f. (Rubiaceae)
(Elsevier Science, 2014-01)
This work reports a comparative study about extraction methods used to obtain anthraquinones (AQs) from stems and leaves of Heterophyllae pustulata Hook (Rubiáceae). One of the conventional procedures used to extract ...
Canola oil with high antioxidant content obtained by combining emerging technologies: microwave, ultrasound, and a green solvent
(Wiley VCH Verlag, 2019-09-09)
In this work, the ultrasound‐assisted extraction (UAE) of canola oil from canola seeds pretreated with microwaves using ethanol 99% as solvent is studied. Different process parameters are evaluated, such as extraction time, ...
Hexane-Free Green Solvent Extraction of Canola Oil From Microwave-Pretreated Seeds and of Antioxidant-Rich Byproducts
(Wiley VCH Verlag, 2018-09)
The ethanol extraction from microwave-pretreated and untreated canola seeds is studied. Two process are used to obtain the oil: in a control process (P1), the solvent-free total extract (E) is washed with hexane, obtaining ...
Ethanol extraction of canola oil: Kinetics and effects of type of solvent and microwave-pretreatmentExtraction de l’huile de colza en utilisant l’éthanol comme solvant : cinétique et effets du solvant et du prétraitement par micro-ondes
(EDP Sciences, 2019-05)
The phenomenon and kinetics of the ethanol extraction of canola oil from microwavepretreated seeds was studied using a Fick’s diffusion model. The extraction was performed in a batch system at constant temperature (313–333 ...
Microwave-assisted extraction applied to Merlot grapes with contrasting maturity levels: effects on phenolic chemistry and wine color
(MDPI, 2019-01)
Merlot grapes were harvested with three maturity levels (21.1, 23.1, and 25.1 Brix), and processed with or without the application of microwave-assisted extraction (MW). The detailed phenolic composition and color were ...
Enzyme assisted extraction of pectin and inulin enriched fractions isolated from microwave treated Cynara cardunculus tissues
(Wiley Blackwell Publishing, Inc, 2020-05)
Artichoke flower heads are consumed fresh or industrialized. Agroindustrial by-products of this plant can be used for the production of dietary fiber. A microwave heating procedure is proposed for polysaccharides concentration ...
Exploring the effect of combined hydrothermal-microwave pretreatment operating conditions on canola oil expression
(Allied Academies, 2017-10)
The effect of the combined hydrothermal-microwave (HT-MW) pretreatment operating conditions on the oil extraction yield by cold pressing was evaluated, as well as its canolol and tocopherols content. Entire and broken ...
Multi-method sensory approach to describe the effect of microwave-assisted extraction and addition of stems on the mouthfeel sensations of Bonarda wines from Mendoza (Argentina)
(PAGEPress, 2022-11-25)
The Bonarda variety has been used as a base for common red wines due to its contribution to color and low level of astringency as a consequence of its relative low tannin concentration. The use of MicrowaveAssisted Extraction ...
Improving the canolol amount and the yield of expressed canola oil applying combined pretreatments
(Universiti Putra Malaysia. Faculty of Food Science and Technology, 2018-05)
Canolol is a potent natural antioxidant. It exhibits antimutagenic and anticarcinogenic properties, showing an even more potent antimutagenic activity than that of α-tocopherol and flavonoids. This compound is formed due ...
D-optimal mixture design for the optimization of extraction induced by emulsion breaking for multielemental determination in edible vegetable oils by microwave-induced plasma optical emission spectrometry
(Elsevier Science, 2020-11)
A sample pretreatment based on an extraction process by emulsion breaking for multi-element determination in edible oils was developed. The determination of eight trace elements (Al, Ba, Cu, Cr, P, Ni, Ti, and Zn) was ...
