[Problem] To provide: a method for suppressing the coloration of oils and fats during frying; and a coloring inhibitor.

[Solution] A method for suppressing the coloration of an oil/fat composition for frying, the method comprising a step for adding a prepared oil to an edible oil or fat, wherein the prepared oil is obtained through (1) a degumming step, (2) a neutralization step which may or may not be performed, (3) a bleaching step which may or may not be performed, and (4) a deodorizing step, in this order, in the process of refining a crude oil obtained from an oil feedstock, and the absorbance difference determined by subtracting the absorbance at a wavelength of 750 nm from the absorbance at a wavelength of 660 nm of the prepared oil obtained from step (3) is at least 0.030 when isooctane is used as the control. A coloring inhibitor characterized by containing said prepared oil.

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 invention relates to process for purifying renewable feedstock comprising at least one acidulated soap-stock, wherein said process comprises the steps, where the renewable feedstock comprising at least one fatty acid is treated in a treating step with an aqueous medium, and a first stream comprising water and a second stream comprising fatty acids are obtained, and the second stream is obtained as purified renewable feedstock.

The present invention relates generally to corn dry-milling, and more specifically, to a method and system for removing insoluble solids mid-evaporation in a corn (or similar carbohydrate-containing grain) dry milling process for making alcohol, such as ethanol, and/or other biofuels/biochemicals. In one example, the method for removing residual insoluble solids in a grain dry milling process includes separating a whole stillage byproduct into an insoluble solids portion and a solubles portion, which includes residual insoluble solids. Then, the solubles portion is subjected to a first evaporation, via one or more evaporators, to remove liquid from the solubles portion to define a concentrated solubles portion. After the first evaporation, the residual insoluble solids are separated from the concentrated solubles portion. And thereafter, the concentrated solubles portion is subjected to a second evaporation, via one or more evaporators, to remove additional liquid from the concentrated solubles portion.

A system for decarboxylating and infusing an organic material includes a decarboxylation and infusion apparatus is provided. The apparatus includes a heated reservoir in operable communication with a user interface whereon a user selects decarboxylation and infusion settings. The heated reservoir has a mixing element to agitate an organic material and solvent disposed therein as well as a filter to filter the organic material following the infusion.

A methodology for cleaning and upgrading any kind of tires (cars, motorcycles, trucks, etc.), any kind of waste lubricants (internal combustion engines, industrial parts), any kind of oils as well as plant and animal fats by means of removal of the inorganic elements (potassium, sodium, chlorine, sulfur, phosphorus and heavy metals such as Pb, Cu, Cd, Zn, Hg, Mn, etc.) and the simultaneous addition of new such as calcium, magnesium and ammonium, in order to produce a clean and upgraded rubber material, lubricant as well as fat/oil, which can be used as raw material in thermochemical conversion processes such as flash (t<1 sec)/fast pyrolysis.

A method for purification of a triacylglyceride oil comprising the steps of concentrating the insoluble components in the melted triacylglyceride oil, by applying a centrifugational force on the liquid triacylglyceride oil whilst maintaining the triacylglyceride oil above its melting temperature; and/or allowing the insoluble components to settle by gravitational force whilst maintaining the triacylglyceride oil above its melting temperature; and separating the triacylglyceride oil from the insoluble components. A triacylglyceride oil obtained by the method of the invention for use in food production is also provided

A method for purification of a triacylglyceride oil comprising the steps: (a) admixing the triacylglyceride oil with an auxiliary trapping agent, wherein the melting temperatures of the triacylglyceride oil and the auxiliary trapping agent are substantially different, wherein the auxiliary trapping agent is soluble in the triacylglyceride oil, and wherein the auxiliary trapping agent is more polar than the triacylglyceride oil; (b) (i) crystallising the auxiliary trapping agent by cooling the mixture of step (a) below the melting temperature of the auxiliary trapping agent, wherein the auxiliary trapping agent has a higher melting temperature than the triacylglyceride oil; or (ii) crystallising the triacylglyceride oil by cooling the mixture of step (a) below the melting 10 temperature of the triacylglyceride oil, wherein the triacylglyceride oil has a higher melting temperature than the auxiliary trapping agent; and (c) separating solid and liquid phases of the product of step (b).

A method for producing hemp oil, comprising decarboxylation of CBDA in hemp oil; short-path evaporation of CBD from the decarboxylated hemp oil to produce CBD oil; selective THC to CBN conversion performed on the decarboxylated hemp oil.
