An oil extractable from corn fiber contains ferulate esters, in particular sitostanyl ester, which has been shown to have cholesterol-lowering activity. The oil is extracted by a novel process which includes a grinding step carried out before extraction with an effective organic solvent such as hexane. The corn fiber oil may be combined with an ingestible and/or edible carrier for administration as a dietary supplement for cholesterol-lowering purposes.

The present invention relates to a process for the preparation of degummed glyceride oils, which comprises applying an acid degumming treatment to a crude glyceride oil which has not substantially been exposed to enzymatic activity. Preferably such crude glyceride oil has been obtained by heating and pressing glyceride oil containing vegetable material, optionally preceded by a cold pressing step, where the heating comprises an exposure of the vegetable material to a temperature of 30.degree.-80.degree. C. for 0.1-20 minutes, preferably for 0.1-15 minutes, more preferably 0.1-5 minutes, and then to a temperature of 80.degree.-140.degree. C., preferably 90.degree.-110.degree. C. for 1-60 minutes, preferably 15-20 minutes. Residual phosphorus levels of

A process for extracting oil from oil-bearing materials, such as vegetable oil bearing seeds and plant materials, is disclosed. The process comprises adding crude oil, water and a reagent to the oil-bearing materials to form a slurry. Subsequently, a resultant oil is extracted from the slurry. The process provides for treating the oil-bearing materials in a screw extruder. In addition, the process teaches sparging the slurry with steam to remove impurities contained therein.A substantially toxic-free feed is obtained by maintaining the oil-bearing materials in acid reagents for about 5 minutes to hydrolyze glucosinolates to carbon dioxide and ammonia. The ammonia and carbon dioxide are subsequently stripped therefrom.

Improvement in the conventional process of recovering palm oil. This process is made continuous by the steps of continuously introducing fresh fruit bunches in a receiving bin; while the fresh fruit bunches are in the receiving bin, treating the fruit bunches with steam to deactivate any enzyme responsible for the formation of free fatty acid in the fruit bunches; continuously removing fresh fruit bunches treated in the receiving bin, separating the loose fruitlets and continuously subjecting same to a combined sterilizing and stripping operation to detach fruitlets from the fruit bunches; continuously feeding the fruitlets, each consisting of a nut surrounded by a pericarp, to a pressurized digester; continuously blowing the digested fruit to a blow tank; and continuously extracting oil by pressing the digested fruit mass.
摘要:
A method of conditioning an oil seed for removal of the hull therefrom for subsequent processing of the meat portion of the oil seed. The method includes a step of passing the oil seed, under the influence of gravity, downwardly through a plenum (26) of an oil seed conditioner (18). A gas is introduced into the conditioner (18), proximate a lower end thereof, through an inlet (32). The gas passes upwardly in a counter-current relationship to the downwardly passing oil seed. A plurality of staves (24) are disposed within the plenum (26) and extend thereacross. Consequently, as the oil seed passes downwardly through the plenum (26) it engages and bounces off the staves (24). Downward movement of the oil seed is retarded by the upward flow of the gas and the staves (24). The impacting of the oil seed against the staves (24) effects loosening of the hulls, and the extended period of time the oil seed is maintained within the plenum (26) facilitates crisping of those hulls.

During processing the soybeans are heated-up in a first of two successively arranged fluidized beds with a rapidity such that the hulls loosen or detach from the seeds and there is obtained a honogeneous heating of all of the soybeans. The heated-up soybeans may be directly conveyed into the second fludized bed where they are maintained in a heated condition and from which location they are infed in a heated state to a breaking or cracking mill where they are crushed or cracked and then to a flaking device for the subsequent flaking thereof. It is also possible to undertake along the conveying path from the first fluidized bed to the second fluidized bed a mechanical dehulling operation at the soybeans where the hulls are separated from the seeds and the seed portions are delivered into the second fluidized bed. At that location, the seed portions are maintained in a heated condition and then they are delivered in a heated state to the breaking or cracking mill where they are crushed or cracked and then to the flaking device where they are subsequently flaked. Processing is accomplished continuously and the material is only heated-up one time.

A process of producing a peanut oil, comprising a first stage of immersing peanut seeds cleared of the skins in hot water for a predetermined period of time, cooking the resultant peanut seeds in an equal volume of hot water at a predetermined temperature under a predetermined pressure for a predetermined period of time, grinding the cooked peanut seeds into the form of slurry, diluting the slurry with an equal volume of hot water, and mechanically fractionating the diluted slurry into a liquid fraction and a solid fraction; a second stage of mechanically fractionating the liquid fraction into a water fraction, an oil fraction and a residual solid fraction; and a third stage of adding an aqueous solution of salt to the liquid fraction obtained in the second stage for forming a layer of peanut oil over a layer of solid constituents, and separating the layer of the peanut oil from the layer of the solid constituents.
摘要:
Process for treating oil containing vegetable raw material by the influence of moisture and heat, whereby during the exposure of a rather thin layer of the oil containing raw materials to a moisture and heat transfer fluid, the raw materials are subjected to a loosening movement by means of a vibration having a substantial vertical component. The frequency of the vibration is 200 - 400 and the vertical amplitude 10 to 40 mm.
