How to extract oil from algae spirulina?
Best insight from top research papers
Oil extraction from Spirulina platensis microalgae can be achieved using various methods. One method is ultrasound-assisted extraction, which involves the use of mixed solvents such as isopropyl alcohol and n-hexane. The experiment showed that a higher yield of oil was obtained using a mixture of 40% isopropyl alcohol and 60% n-hexane, while the lowest yield was obtained using 100% n-hexane . Another method is supercritical CO2 (SCCO2) extraction, which has advantages such as lower toxicity and no solvent-liquid separation. Adding methanol as a cosolvent in SCCO2 extraction significantly increased the lipid extraction yield for Spirulina sp. and Schizochytrium sp. species. A stepwise addition of methanol was found to be more effective than a one-time addition . Additionally, extraction with supercritical CO2 without pretreatment resulted in a yield of 10 mg/g of dry biomass, while microwave pretreatment for 5 minutes increased the yield to 40 mg/g of dry biomass .

How to extract oil from fish?5 answersFish oil can be extracted using various methods such as supercritical fluid extraction (SFE-CO2), enzymatic hydrolysis extraction after ultra-high pressure pre-treatment (EHSUP), modified soxhlet extraction, and ultrasound-assisted extraction (UAE) and microwave-assisted extraction (MAE). In SFE-CO2, the oil is extracted using supercritical conditions of time, temperature, and pressure. EHSUP involves pre-treating the fish heads with ultra-high pressure before enzymatic hydrolysis. Modified soxhlet extraction uses solvents like ethanol to extract the oil. UAE and MAE are novel technologies that utilize ultrasound and microwave to extract oil from fish by-products. Each method has its own advantages in terms of oil yield, fatty acid composition, and extraction efficiency.
What are the different methods of extracting oil from microalgae using alcoholes?5 answersDifferent methods of extracting oil from microalgae using alcohols include the Soxhlet method, Bligh and Dyer method, Folch method, Hara and Radin method, and the supercritical carbon dioxide entraining ethanol method. The Bligh and Dyer method, using 2-methyltetrahydrofuran (2-MeTHF) and cyclopentyl methyl ether (CPME) as solvents, extracted lipids from microalgae with high yields. The supercritical carbon dioxide entraining ethanol method is non-toxic, selective, and environmentally friendly, making it a safer alternative to conventional organic solvent extraction methods. Ultrasonic-assisted extraction and stirring are also used to extract oil from microalgae, with parameters such as temperature, pressure, ultrasonic power, and frequency affecting the extraction rate. Other methods mentioned in the abstracts include expeller/oil pressing, single solvent extraction, microwave-assisted extraction, enzymatic extraction, ultrasound-assisted extraction, oxidative stress, electroporation, and osmotic shock.
