Aqueous extraction processing (AEP) of soy is a promising green alternative to hexane extraction processing. To improve AEP oil yields, experiments were conducted to probe the mechanisms of oil release. Microscopy of extruded soy before and after extraction with and without protease indicated that unextracted oil is sequestered in an insoluble matrix of denatured protein and is released by prot...

Marigold (Tagetes erecta) flowers are a rich source of organic solvents. In this study, lutein was extracted from marigold flowers with enzyme extraction without using organic solvents. Extraction produced oil that contained 0.36 mg/ml lutein (present as lutein esters but calculated as free lutein), and the yield was comparable to solvent extraction. The oil containing lutein was used to produc...

In this study, the subcritical butane extraction process of fenugreek seed oil was optimized using response surface methodology with a Box-Behnken design. The optimum conditions for extracted oil from fenugreek seed was as follows: extraction temperature of 43.24 °C , extraction time of 32.80 min, and particle size of 0.26 mm. No significant differences were found between the experimental and p...

opium poppy (papaver somniferum l.) has two major products: alkaloids in the capsules and the seeds.  the seed contains oil, protein, carbohydrate, moisture and mineral matters. the seed oil is rich in unsaturated fatty acids, particularly linoleic and oleic acid. remaining meals after oil extraction are the important source for animal diets. the united nations recognize turkey and india as tra...

Supercritical carbon dioxide (SC-CO(2)) extraction of oil from oak silkworm pupae was performed in the present research. Response surface methodology (RSM) was applied to optimize the parameters of SC-CO(2) extraction, including extraction pressure, temperature, time and CO(2) flow rate on the yield of oak silkworm pupal oil (OSPO). The optimal extraction condition for oil yield within the expe...

14 Regulatory, safety, and environmental issues have prompted the development of aqueous 15 enzymatic extraction (AEE) for extracting components from oil-bearing materials. The 16 emulsion resulting from AEE requires de-emulsification to separate the oil; when enzymes 17 are used for this purpose, the method is known as aqueous enzymatic emulsion de18 emulsification (AEED). In general, enzyme a...

Purpose: To determine the effects of temperature, pressure and extraction time on oil yield obtained from Polygonatum odoratum as well as the optimum processing conditions for supercritical carbon dioxide (CO2) extraction. Methods: Supercritical CO2 extraction technology was adopted in this experiment to study the process of extraction of volatile oil from Polygonatum odoratum while gas chromat...

In this paper the extraction of oils from trout waste is investigated. Trout heads, viscera and spine, obtained from a fish-processing company, have been separately freeze-dried and then extracted. Two different solvent extraction techniques have been utilized and compared: the common soxhlet extraction, which utilizes n-hexane at atmospheric pressure as solvent, and the supercritical CO2 extra...

The effects of enzyme action and heat pretreatment on oil extraction yield from sunflower kernels were analysed using hexane extraction with Soxhlet, and aqueous extraction with incubator shaker. Ground kernels of raw and heat treated kernels, each with and without Viscozyme treatment were used. Microscopic images of the kernels were taken to analyse the visible effects of each treatment on the...

Microwave-assisted hydro distillation MAHD of eucalyptus citriodora. oil was investigated and a comparison was made with conventional hydro distillation. For MAHD, three process parameters; Microwave power, Extraction time and duration of dryness of sample were selected for the extraction. MAHD resulted in a shorter extraction time and better quality of oil compared to that in conventional hydr...
