Magnetic-Field-Assisted Extraction of Astaxanthin from H aematococcus pluvialis

Abstract

Magnetic-field-assisted extraction (MFAE) technique was employed to extract astaxanthin from Haematococcus pluvialis. The process for extraction of astaxanthin was optimized using response surface methodology, employing a three-level, three-variable Box-Behnken experimental design. The results showed that the optimum extraction conditions were as follows: liquid-solid ratio 77:1 (v/w), magnetic intensity 18 mT and extraction 50 min. Under the above mentioned conditions, the astaxanthin yield was 62. 72%. The experimental yield under optimal conditions was in good matching with the predictive yield. Magnetic intensity increased the efficiency of enzymatic treatment with higher extraction yield, which indicated that MFAE is a more efficient process as compared to other extractions. PRACTICAL APPLICATIONSMagnetic field extraction was applied as a novel separation technique, which had many advantages on the extraction of astaxanthin compared to the traditional extraction method, such as good stability. The knowledge provided by this work may promote the application of magnetic field extraction method in the food industry. In addition, the development results in creating environmentally friendly processes.

Optimization of carotenoids extraction from blue crab (Portunus pelagicus ) and shrimp (Penaeus semisulcatus ) wastes using organic solvents and vegetable oils

“…They obtained the highest carotenoid yield (363.94 µg g −1 hepatopancreas) via an optimum condition providing a solvent ratio of 4.5:1 (v/w) and three repetitions for each extraction. Zhao Fu, Liu, Zhu, Wang, and Bi () used the magnetic‐field‐assisted extraction technique to extract astaxanthin from H. pluvialis by using the response surface methodology, employing a three‐level, three‐variable Box–Behnken experimental design. The results showed that the optimum extraction conditions were a liquid–solid ratio of 77:1 (v/w) through the extraction duration 50 min.…”

Magnetic Technologies and Green Solvents in Extraction and Separation of Bioactive Molecules Together with Biochemical Objects: Current Opportunities and Challenges

“…Astaxanthin is a carotenoid that has many physiological activities, such as antioxidant, anticancer, immunity enhancement, and improvement of eyesight. Zhao et al [135] also used magnetic field-assisted extraction technology to obtain astaxanthin from Haematococcus pluvialis. In their study, the experiment was carried out in an electromagnetic system (Shandong University, Jinan, China), and they found that when the magnetic field intensity was 15 mT, the extraction rate was 1.2 fold the rate without the effect of a magnetic field.…”

Meeting Sustainable Development Goals: Alternative Extraction Processes for Fucoxanthin in Algae

“…The fucoxanthin-containing solvent fraction retrieved from the solvent extraction (e.g., ethanolic stream) could be directly subjected to the liquid-liquid separation systems like aqueous two-phase system (Gómez-Loredo et al, 2014, 2015 or highspeed countercurrent chromatography (Xiao et al, 2012). Prospectively, the simultaneous extraction and purification of fucoxanthin can be accomplished by integrating biphasic separation techniques with the emerging extraction techniques assisted by ultrasound, electricity, microwave, magnetic field and bubbles (Zhao et al, 2016;Sankaran et al, 2018;Chew et al, 2019;Khoo et al, 2019;Leong et al, 2019).…”
