There is a method for extracting bio-oil from algal biomass, in particular oily microalgae, using solvents of a Deep Eutectic Solvents (DES) capable of producing a bio-oil with a low content of phospholipids and inorganic salts, mainly sodium chloride.

A method for preparing field muskmelon oil includes the following steps: S1, removing foreign matter, including: removing the foreign matter in field muskmelon seeds; S2, low-temperature pressing, including: performing the low-temperature pressing on the field muskmelon seeds after removing the foreign matter in step S1 to obtain an oil residue mixture; S3, filtering and removing impurities: filtering the oil residue mixture obtained by the low-temperature pressing in step S2 to remove the impurities to obtain a primary oil; and S4, centrifugal separation, including: centrifugally separating the primary oil obtained by filtering and removing impurities in step S3 to obtain the field muskmelon oil. The new method avoids using high-temperatures resulting in optimal yield of nutritional content and no harmful byproducts.

A product matter of generally expanding the life of edible cooking oil used to deep fry wherein a combination of diatomaceous earth and anhydrous magnesium silicate are used as a fry and filtering aid.

A method for producing a carotenoid enriched fatty acid composition includes: reacting an oil including free fatty acids and carotenoids with a basic solution; withdrawing, separately from the oil, an extraction solution including at least a portion of the free fatty acids, at least a portion of the carotenoids, and the basic solution; acidifying the extraction solution to produce an aqueous phase and a fatty acid phase, the fatty acid phase including the free fatty acids and the carotenoids of the extraction solution; and separating the fatty acid phase from the aqueous phase.

A system for further filtering a liquid extract material after an initial extraction process. In an embodiment, the system includes a semi-rigid filter cup that is substantially cylindrical, the filter cup having a top and a bottom, wherein the top is oriented to receive filter media prior to a filtration process, and material to be filtered during the filtration process. The filter cup includes an integrated deformable flange at the top of the filter cup, an integrated top o-ring that is integrated into the top of the integrated deformable flange and an integrated bottom o-ring that is integrated into the bottom of the integrated deformable flange.

The present disclosure provides an extraction method of natural crocodile oil. The method improves the traditional ancient method of making oil, and includes: mixing crocodile fat with a traditional Chinese medicine bag and standing, then taking out the fat, and sequentially pulping and filtering. By using the above method, any extracts are not added without decolorization, the effective ingredients in the crocodile oil can be maintained to the greatest extent to the greatest extent, and therefore the method of the present disclosure is suitable for large-scale production. The present disclosure further provides the crocodile oil obtained by the extraction method. The crocodile oil is glittering and translucent, has no fishy smell, and can be preserved for a long time.

There is described a process for producing biodiesel and related products from mixtures. There is also described a process for producing precursors and feedstock materials for producing biodiesel and related products. The processes use esterification and trans-esterification, separation and purification. Other process steps such as acidification and distillation can also be used.

The present disclosure is generally directed to methods for purifying cannabinoids from Cannabis plants.

The invention relates to a method for the purification of crude rice bran wax using an alcohol as a purifying solvent under high pressure conditions. It particularly relates to the use of ethyl alcohol as said solvent for efficient and economic purification of crude rice bran wax into economically valuable high purity wax products.

The present disclosure relates methods and systems for refining grain oil compositions using water, and related compositions produced therefrom. The present disclosure also relates to methods of using grain oil derived from a fermentation product in an anti-foam composition and/or feedstock to make diesel.
