“…In this case, a higher extraction temperature and longer irradiation time also resulted in the degradation of astaxanthin with a similar result observed by Ruen-ngam et al [145]. In another study, the effect of the ultrasonic treatment on microalgal cell disruption was investigated by evaluating the release of intracellular carotenoids from the green microalga, Chlamydomonas reinhardtii [154].…”

“…In one study, a closed system MAE resulted in the highest astaxanthin recovery from marine alga H. pluvialis in a shorter duration (5 min) when compared to conventional solvent extractions and ultrasound assisted extractions (UAE), at a time of 60 min for the recovery of astaxanthin [145]. Acetone was found to be a suitable solvent for the recovery of astaxanthin when compared to methanol, ethanol and acetonitrile.…”

“…MAE at a temperature of 75 °C resulted in 74% recovery of astaxanthin. A temperature above 75 °C in the microwave system caused a rapid loss in the recovery of astaxanthin [145]. Most of the carotenoids are temperature sensitive due to their structure and chemical bonding and can undergo isomerization and/or degradation at elevated temperature [146,147].…”

Marine microalgae and seaweeds (microalgae) represent a sustainable source of various bioactive natural carotenoids, including β-carotene, lutein, astaxanthin, zeaxanthin, violaxanthin and fucoxanthin. Recently, the large-scale production of carotenoids from algal sources has gained significant interest with respect to commercial and industrial applications for health, nutrition, and cosmetic applications. Although conventional processing technologies, based on solvent extraction, offer a simple approach to isolating carotenoids, they suffer several, inherent limitations, including low efficiency (extraction yield), selectivity (purity), high solvent consumption, and long treatment times, which have led to advancements in the search for innovative extraction technologies. This comprehensive review summarizes the recent trends in the extraction of carotenoids from microalgae and seaweeds through the assistance of different innovative techniques, such as pulsed electric fields, liquid pressurization, supercritical fluids, subcritical fluids, microwaves, ultrasounds, and high-pressure homogenization. In particular, the review critically analyzes technologies, characteristics, advantages, and shortcomings of the different innovative processes, highlighting the differences in terms of yield, selectivity, and economic and environmental sustainability.

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.

“…The conventional extraction method is extraction by means of maceration method using different types of organic solvent. Generally this method is used as an elementary method in extracting many valuable compounds [1], [2]. The important parameters which might be affected on amount of obtained substance are the time, the material and the solvent ratio and type of solvent.…”

Abstract-Gamma-Oryzanol is one type of antioxidant and has a good effect for health. Gamma-Oryzanol can be fould in rice bran which is the waste from rice milling process. Upland rice is one type of rice which can be grown in the upland area especially in the southern part of Thailand. The upland rice with species of Dawk Pa-yawmhas has been used in this research. There are many ways to extract gamma-oryzanol from rice bran. Maceration is conventional and useable extraction method in gamma-oryzanol extraction. Solvent is one crucial parameter in extraction. Many types of organic solvent such as hexane ethyl acetate acetone isopropanol and ethanol are investigated here. The extraction conditions such as the effect of soaking time, rice and solvent ratio also examined. The highest amount of rice bran oil obtains from acetone as solvent with the ration of rice bran and solvent is 1:4. Moreover the extracted product is also quality checked by HPLC method. The chromatogram clearly shows the peak of gamma-oryzanol.Index Terms-Dawk Pa-yawn upland rice, Gamma-oryzanol, maceration, rice bran.
