Selection of extraction solvents for edible oils from microalgae
The organic solvent extraction method is always adopted to produce edible oil based on the principle of similarity compatibility, which as a high oil extraction rate, and edible oil can be
For supercritical CO 2 as an alternative solvent, the extraction process n-butane or DME have been extensively investigated for the extraction of fats and oil, antioxidants and aromas
Edible Oil as an Alternate Solvent for Extraction
the organic solvents by edible oils in the extraction of the active antioxidant components from herbs and spices. Key words: Edible Oils, Sunflower Oil, Organic Solvent, Plant herbs and Spices
This risk can be prevented by the addition of food grade antioxidants to the solvent. 2-MeOx is the result of the hydrogenation of furfural, a derivative of pentoses obtained after acid
Selection of extraction solvents for edible oils from microalgae
The results displayed that, by using the ethanol/n-hexane (3:2, v/v) mixed solvent, the oil extraction rate from wet algal mud was 68.31 %, with 71.65 % of neutral lipid, and 1.87 % of vitamin E; the
Jan 1, 2006Edible vegetable oil has been reported to have potential as an alternative solvent or co-solvent in the extraction of desired compounds [27] [28][29][30]. In addition, other study also
An Overview of Natural Extracts with Antioxidant Activity
Many plant materials, such as fruits and vegetables as well as herbs and spices, represent valuable sources of antioxidants. In recent years, wastes from agriculture and food
Sunflower and soy oil were used as alternative solvents to study the effect of various parameters on the yield between ultrasound and conventional extraction, in which the optimal conditions for
Aqueous and enzymatic processes for edible oil extraction
Nov 1, 1996Industrial processes for the extraction of edible oil from oilseeds generally involve a solvent extraction step which may or may not be preceded by pressing. The aqueous
Jan 1, 2004The U.S. Food and Drug Administration (FDA) regulatory considerations about the edible oil extraction solvents are discussed. It is found that extracting solvents used in food

Expeller pressing and organic solvent extractions are common methods for oil extraction in the food industry . However, these two methods come with some concerns, such as
Introduction to cold pressed oils: Green technology, bioactive
Current environmental issues associated with organic solvent disposal demand alternative methods for the extraction of edible oils that are environmentally friendly and energy
The use of antioxidants in foods is regulated in many countries including United States, Canada, Australia, and many European countries (Mikova, 2001, Shahidi and Zhong, 2005,

Sea buckthorn, an ancient medicinal plant, is gaining attention because of its prodigious antioxidant activities.Microwave-assisted (MAE) and Soxhlet extraction techniques
- Can edible oil replace organic solvents for extracting antioxidant components?
- The current study aimed at evaluation of edible oil (sunflower oil) to replace organic solvents for extracting the active antioxidant components from plant herbs and spices (rosemary, thyme and sage) by a number of chemical assays. Assays included reducing power, β-carotene-linoleic acid model system and inhibition of conjugated diene formation.
- Can edible oil be used as a solvent?
- Edible vegetable oil has been reported to have potential as an alternative solvent or co-solvent in the extraction of desired compounds . In addition, other study also reported that the edible oils such as olive oil as a solvent in extraction process may retain the stability of TC other than petroleum-based solvents . ... ...
- Are vegetable oils a good alternative solvent?
- They should be obtained from renewable resources at a reasonable price and be easy to recycle. Based on the principles of Green Chemistry and Green Engineering, vegetable oils could become an ideal alternative solvent to extract compounds for purification, enrichment, or even pollution remediation.
- Can natural antioxidants improve oxidation stability of microalgae edible oil?
- A combination of natural antioxidants was optimized to improve the oxidation stability of microalgae edible oil. Microalgae are natural, green raw material and could be used for the development of edible oil for its abundant polyunsaturated fatty acids, with fast growth rate.
- Which lipid is the main component of edible oil & plant oil?
- Neutral lipid is the main component of edible oil and plant oil. Vitamin E has antioxidant properties, and the higher the content is, the stronger the protective effects are on the microalgal oil. Physico-chemical properties are the physical and chemical indicators of crude edible oil, including colour, acid value, peroxide value.
- Can microalgae be used to make edible oil?
- Microalgae are natural, green raw material and could be used for the development of edible oil for its abundant polyunsaturated fatty acids, with fast growth rate. The wet mud and dry powder of Scenedesmus dimorphus were applied to compare the extraction effects of different organic solvent systems in this study.
