  • Patent number: 9580371
    Abstract: The present invention is in the field of organic and natural product chemistry. The present invention relates to an efficient process for purification, simultaneous extraction, and separation of monohydroxycarotenoids from dihydroxycarotenoids in various natural products or in synthetic mixtures. Similarly, the process can also be applied to the simultaneous extraction, saponification, and separation of esterified mono- and dihydroxycarotenoids in natural products and their oleoresins or in their synthetic mixtures. Therefore, esterified and unesterified monohydroxycarotenoids such as (3R)-?-cryptoxanthin and (3R,6?R)-?-cryptoxanthin can be efficiently separated from their corresponding dihydroxycarotenoids such as (3R,3?R,6?R)-lutein and (3R,3?R)-zeaxanthin that are found in various plants or in synthetic mixtures.

  • Patent number: 7638643
    Abstract: It is intended to easily separate saponins from isoflavones extracted from starting soybeans thereby giving highly pure saponins at a high yield on an industrial scale. Saponins can be highly efficiently separated from isoflavones by performing multistage extraction under mild conditions such that malonyl isoflavone glycoside, from among isoflavones contained in the starting soybeans, is not converted into isoflavone glycoside, acetyl isoflavone glycoside or isoflavone aglycon. Thus, highly pure saponins can be obtained at a high yield on an industrial scale.

  • Patent number: 7622599
    Abstract: The present invention explains a realistic and effective process for isolating and purifying carotenoids containing higher concentrations of carotenoids such as trans-lutein, trans-zeaxanthin, Cis-lutein, ?-carotene and Cryptoxanthin from Marigold flower petals under controlled conditions leaving no traces of any organic hazardous solvents. The process involves ensilaging Marigold flowers, dehydration, solvent extraction, alkali hydrolysis of carotenoid esters with absolute alcohol, crystallization/purification using water, absolute alcohol mixture followed by filteration and drying until the crystals are considerably free from moisture and absolutely free from residual hazardous solvents. These crystals are suitable for nutraceutical and food products as supplements.

  • Patent number: 7615657
    Abstract: The invention describes a method of producing extracts from the seeds of meadowfoam, brassicas and crambe plants. A number of subsidiary processes and steps are shown in order to extract differing fractions of oil. Products produced from the above method are also described including uses and methods of these products which include a variety of skin conditions including eczema, facial eczema, dermatitis, external ulcers, welts, rashes, insect bites, allergic reactions and other irritations, burns, wounds, psoriasis, acneiform eruptions, dryness, dry skin, irritation, skin atrophy, secondary infections and the like. The extracts are also described as being a useful compound for treatment of the symptoms of such skin conditions as described above. In particular the use and extraction of glucosinolate (GSL), thiocyanates (TCL) and isothiocyanates (ITCL) is described.

  • Publication number: 20090028971
    Abstract: The invention relates to a method for obtaining natural oils from plant constituents, said method being essentially carried out using compressed C2-C4 hydrocarbons. Residues from the crop and fruit treatment, especially from the treatment of pips and berries, are used as starting materials. Unlike previous extraction methods using organic solvents, the inventive method can be economically carried out on the basis of low pressures and reduced extraction agent throughputs. Preferred extraction agents are ethane, propane, butane and the mixtures thereof, the extraction itself being carried out in batches at pressures of <50 mPa and temperatures of ?70° C., with an extraction agent throughput of between 4 and 20 kg/kg of starting materials. The extracted oils are outstandingly suitable for flavouring preparations and cosmetic formulations, especially for the care and treatment of the skin.

  • Patent number: 7390914
    Abstract: A method for concentrating trans-xanthophyll esters from marigold oleoresin, which includes blending the oleoresin with a solvent and a co-solvent of lower alkanols and recovering a precipitate enriched with trans-xanthophyll esters at a temperature of above 22° C. The recovery of the trans-xanthophyll esters is greater when using the alkanol blend than when using only a lower alkanol from the said blend. The said process is most useful using a lower-grade, commercially available oleoresin, thereby helping small producers, who do not have access to higher-grade oleoresin made through backward integration to marigold cultivation and harvest.

  • Patent number: 7259269
    Abstract: A method for obtaining an oil fraction and a protein fraction from a vegetable starting substance comprises the steps of: extracting the starting substance which has been reduced in size with alcohol, and separating an alcohol liquid phase from the extracted starting substance; processing the alcohol liquid phase to obtain the oil fraction; avoiding drying of the alcohol wet extracted starting substance directly after the alcohol-extraction; transferring the still alcohol wet extracted starting substance into an aqueous suspension to reduce the alcohol content of the extracted starting substance below 5%; and processing the aqueous suspension to obtain the protein fraction.

  • Patent number: 7156981
    Abstract: A process for the producing edible protein-containing meal for human and animal consumption and high quality food grade oils from oil seed using iodotrifluoromathane as the solvent is shown. The meal has a significantly improved level of dietary available (absorbable) protein. The process involves the preparation of protein isolates by a procedure which is conducted at room temperature, thus decreases protein degradation and denaturing which is caused by elevated temperatures. The process also provides for extraction of substantially all oils and fats, which interfere with the formation of the protein micelle, from the protein meal providing a cleaner, purer product with high levels of absorbable protein. Such protein isolates can then be used as such or added to formulated foods in order to increase the total protein content of that food. The protein produced and the oils recovered have compositions which are also unique and unobtainable by prior processing methods.

  • Patent number: 7148366
    Abstract: A process for removing oil from an agricultural substrate, including a dry grind corn. An ethanol solution with a concentration in the range of from about 90% to about 100% ethanol is mixed with the dry grind corn in a ratio of from about 10:1 to about 1:1 to form an extraction solution including the ethanol solution, oil, and corn solids. The extraction solution is separated into the corn solids and a filtrate, the filtrate including the ethanol solution and oil. The filtrate is membrane filtered, including nanofiltration, to restrain an oil concentrate from the filtrate and pass a permeate of the ethanol solution. The oil contained within the oil concentrate is purified.
