Present invention relates to a novel process for purification of feedstocks.

Disclosed herein are processes for obtaining a microbial oil comprising one or more polyunsaturated fatty acids (PUFAs) from one or more microbial cells by lysing the cells to form a lysed cell composition, treating the lysed cell composition to form an oil-containing emulsion and then recovering the oil from the oil-containing emulsion. Further disclosed herein is microbial oil comprising one or more PUFAs that is recovered from microbial cells by at least one process described herein.

The present disclosure relates to a novel process for removing or reducing inorganic and organic chloride containing compounds from a feedstock.

Described herein is a polymerized biorenewable, previously modified, or functionalized oil, comprising a polymeric distribution having about 2 to about 80 wt % oligomer content, a polydispersity index ranging from about 1.30 to about 2.20, and sulfur content ranging from 0.001 wt % to about 8 wt %. Methods of manufacturing the polymerized oil as well as its incorporation into asphalt paving, roofing, and coating applications are also described.

It is an object of the present invention to provide a novel technique related to electric field treatment of edible oil.

The present invention is an electric field treatment device for edible oil, the device including: an energization unit that is capable of being installed in at least one of side surface regions of an oil reservoir having a heating unit, wherein the heating unit is capable of heating a side surface and/or a bottom surface of the oil reservoir, and is capable of forming heat convection of the edible oil in both directions of the side surface region including the energization unit in the oil reservoir and a central region in the oil reservoir, and the energization unit is capable of applying an alternating electric field to the edible oil provided in the oil reservoir, includes at least two electrodes having a gap or a hole which is a path of heat convection of the edible oil and locally increases an electric field intensity applied to the edible oil, and applies the alternating electric field.

The process of reuse lysogoma, applied in the pre-treatment of already degummed oil for subsequent PLA treatment and transesterification of biodiesel object of the present invention comprises a pre-treatment step through the reuse of lysogoma originating from the PLA enzymatic treatment in the oil already degummed. The use of lysogoma containing active enzymes resulting from the enzymatic treatment (11) on the already degummed oil (40) aims to reduce the levels of phosphorus, calcium and magnesium. In short, the use of lysogoma (10) is presented as a pre-treatment as it aims to reduce the contents of phosphorus, calcium and magnesium present in the degummed oil. Furthermore, this new process impacts the reuse of a byproduct with no commercial value that helps to significantly reduce the contents of phosphorus, calcium and magnesium, which negatively interfere in the processes, especially in the PLA enzymatic treatment and transesterification steps for biodiesel production.

Methods of refining palm oil in order to produce a refined, bleached and deodorized palm oil with reduced level of 3-monochloropropane-1, 2-diol (3-MCPD) ester are disclosed. The methods may include premixing a palm oil with an acid to chelate metals and form a reaction mixture, and subjecting the reaction mixture to hydrodynamic cavitation mixing for less than 1 second.

A method for extracting oils from sauces while simultaneously determining fat content, peroxide value, and acid value is disclosed. The method is simple to operate and requires uncomplicated equipment. It features a short testing cycle and high efficiency, and suitable for the extraction of oils from oil-rich emulsified encapsulated sauces (such as salad dressings) with high extraction rates. The determination of peroxide value and acid value is not affected by pretreatment methods, ensuring more representative results. It addresses the challenges of difficult oil separation and extraction from oil-rich emulsified encapsulated sauces and solves significant issues encountered when using acid hydrolysis and alkaline hydrolysis methods to determine peroxide value and acid value. It enables the simultaneous monitoring of three physicochemical indicators (fat content, peroxide value, and acid value). This high-efficiency method is particularly suitable for tracking and monitoring during the production process, thereby enhancing production efficiency and reducing production costs.

In general, one aspect disclosed features a process for degumming of lipid-containing compounds for fuel feedstock, the process comprising; receiving a lipid-containing compound (LCC); degumming the LCC using at least one acid in an acid degumming stage to produce a partially-degummed LCC; and degumming the partially-degummed LCC using at least one chelate in a chelate degumming stage to produce a degummed LCC.

In general, one aspect disclosed features a product produced by a process for treating a lipid containing compound (LCC), the process comprising: producing a first mixture having a pH lower than 2 by vigorously mixing an acid with the LCC; and producing a second mixture having a pH between 2.5 and 7 by adding a base to the first mixture, wherein a majority of free fatty acid in the second mixture is not converted into soapstock.
