Abstract: A method of brewing a fluid extract using a filter pouch containing flavor extractable particles. One step is supporting a fully compliant, fluid-permeable filter pouch partially filled with flavor extractable particles such that the pouch is inclined at an angle to horizontal ranging from about 30° to about 90° so that the particles accumulate at a bottom end of the filter pouch. Another step is directing brew water to near an upper end of the filter pouch above the particles. The brew water enters the filter pouch without the need for an opening in the pouch, and drops to infiltrate the particles. The particles are partially fluidized by and suspended in the brew water and they rise with the brew water into an empty portion of the filter pouch without a need for opposing sides of the filter pouch to separate to generate internal space. A further step includes brewing a fluid extract from the particles in the filter pouch and discharging the fluid extract from the filter pouch.

Abstract: An efficient process for recovering high quality corn oil from corn germ. The process involves pre-treating corn germ by Rehydration, conditioning and, optionally flaking. This is followed by extrusion, which is the core operation in the preparation of corn germ for corn oil recovery. Water is provided up front in the process, prior to extrusion. Providing water up front reduces generation of fines and improves friction within the extruder, thereby allowing the material to move along and improving overall efficiency and streamlining of the process. The oil released from corn germ by this process is of high quality and high yield.

Abstract: The present invention provides for optimal extraction conditions for extracting yellow mustard gum from yellow mustard bran to provide for high yield. The four variables examined were extraction temperature, pH, water:solid ratio and extraction time. Of these variables, temperature and pH had a much greater influence on the yield and rheological properties of the extracted gum compared to water/solid ratio and extraction time. Optimum extraction conditions were temperatures between 50-70° C., pH 7-10, water/solid ratio of 40:1-60:1 and extraction time of 2-2.5 hr. The yield of gum obtained under the optimum extraction conditions was 30% of bran weight. The extracted gum exhibited maximum shear thinning flow behaviours. It can be incorporated into cosmetic products and skin lotions.

Abstract: A process for the isolation of simmondsins from jojoba meal is disclosed. Simmondsins are first extracted from defatted jojoba meal with water. After separation from the meal, this water extract is subsequently dried, leaving the simmondsins in the resulting solid.

The first solvent fraction, which is a substantially protein-free concentrate of simmondsins, may be separated from the solid phase, and the ethanolic solvent may then be readily removed, for example, by drying. Residual simmondsins remaining in the meal following extraction with the first ethanolic solvent may also be recovered by a second extraction with ethanolic solvent.

Abstract: The extraction of native products is rendered difficult by the fact that attraction forces act between the liquid native products which are not water-soluble and the tissue incorporating them, and that other constituents are dissolved or present in the form of particles in suspension in the products during the extraction process. The initial substance mixture is, therefore, processed together with a water-soluble, organic solvent and optionally water to form a paste. The addition of the water-soluble, organic solvent enables the substance mixture to be separated cleanly into an aqueous phase and an organic phase in the centrifugal field, no further cleaning being necessary for the organic phase. The process according to the invention has a wide area of application. In principle, it can be applied to all substance mixtures containing liquid, organic substances, in particular to vegetable and animal tissue.

Abstract: A non-pungent dijon mustard flavoring has been isolated as a water soluble extract of brown mustard seed bran. This non-pungent dijon mustard flavoring is useful in a variety of foods and, particularly, in mustard pastes containing yellow mustard seed, brown mustard seed, or mixtures thereof, because the addition of the extract to such mustard pastes increases their dijon flavor character without altering pungency. The extract can be isolated by contacting the brown mustard seed bran with water or an aqueous solution and separating the residual bran solids from the extract-containing water. The extract can then be blended with any food product in which a dijon flavoring is desirable. With respect to mustard paste, brown mustard seed bran can alternatively be mixed with the other conventional mustard ingredients (which include water) and ground to withdraw the water soluble bran extract.

Abstract: The extraction of natural products from material of biological origin is enhanced and accelerated by concurrent contact with extractant medium and exposure to microwave radiation. Normally the extractant medium is selected to be transparent to the microwave and to remain at ambient temperature: however, if some heating of the medium is permissible it may be partially transparent. Sufficient extractant medium should be present to effect the desired extraction. The extraction products are recovered by standard procedures. Materials used for extraction include mint, sea parsley, cedar foilage and garlic. Extractants may be for instance hexane, dichloromethane or ethanol. Extractions may be in two or more stages with different extractants used in each stage. Some of these extraction products are found to be novel, and quite distinct from steam distillation products.
