Provided are methods to destabilize emulsion feedstocks. In the methods, a moderate temperature is applied to the feedstock to create a first mixture. The moderate temperature may be between 120 and 220 degrees Celsius. The first mixture is mixed at the moderate temperature, such as by staged mixing in some embodiments. Moreover, the first mixture is retained at the moderate temperature for up to six hours. The first mixture is separated into an oil phase, convoluted phase, and a water phase. In some embodiments, the moderate temperature may be 125 to 150 degrees Celsius, such as between 125 and 130 degrees Celsius. Moreover, the first mixture may be retained at the moderate temperature for between forty-five minutes and four hours, such as from two to four hours. The separation may occur at the moderate temperature.

A method for extracting compounds from plant material utilizing terpenes as a solvent is described. The invention includes the excitation of the plant material and terpene solvent with microwave, ultrasound, heat input, and physical agitation or combinations thereof. The invention particularly covers the process as it relates to the extraction of THC and CBD and their derivatives from cannabis and hemp for the use in products for medical and recreational use. The combinations of terpene saturant, plant material strain and process variables can be tuned in order to dial in the final resultant product for several variables including but not limited to terpene content, THC or CBD potency, ratios of THC or CBD and their derivatives, or flavor profile.

A method is provided for preventing or reducing the formation of monochloropropanediols (MCPDs) or monochloropropanediol esters (MCPDEs) in triacylglyceride oil, comprising the steps: (a) admixing the triacylglyceride oil with (1) an auxiliary oil wherein the auxiliary triacylglyceride oil has higher phospholipid and/or wax content than the triacylglyceride oil; and/or (2) the gum extract from an oil; (b) degumming the triacylglyceride oil admixture and/or optionally allowing the insoluble components to crystallize; (c) optionally concentrating the insoluble and crystallized components from the triacylglyceride oil admixture (1) by applying a centrifugational force on the triacylglyceride oil admix and/or (2) by allowing the insoluble and crystallized components to settle by gravity; (d) separating insoluble and crystallized components from the triacylglyceride oil admixture and/or optionally applying one or more processes selected from degumming, physical refining, chemical refining, neutralization, interesterification, bleaching, dewaxing and fractionation; (e) applying heat treatment to the triacylglyceride oil admixture.

A preparation method of eicosapentaenoic acid (EPA) ethyl ester is provided and relates to the field of EPA ethyl ester processing technologies. The preparation method includes: performing degumming and deacidification on a sardine crude oil to obtain a semi-refined sardine oil, performing esterification on the semi-refined sardine oil to obtain an esterified sardine oil and then performing winterization on the esterified sardine oil to thereby obtain an semi-refined esterified sardine oil, performing bleaching and deodorization on the semi-refined esterified sardine oil, and performing multi-stage distillation treatment. Finally, the sardine oil is purified by liquid chromatography to obtain the high purity EPA ethyl ester. The preparation method can improve a utilization rate of the sardine oil and obtain the high-purity EPA ethyl ester.

The present disclosure is related to an apparatus and method for purification of biological feedstock, such as reducing or removing nitrogen containing compounds therein. The method can include subjecting the feedstock to a first separation step for obtaining a first fraction containing free fatty acids and nitrogen containing compounds, and collecting the residue containing acylglycerols. The first fraction is reacted with glycerol to obtain acylglycerols from the free fatty acid therein. This fraction is subjected to a second separation step for obtaining a second fraction containing nitrogen containing compounds, which is discharged as waste-product. The remains from the second separation contain formed acylglycerols and are collected.
