Systems and methods to reduce pour point (PP) temperatures of fat-based compositions for use in transportation fuels. In one or more embodiments, methods and systems reduce the pour point of rendered fats using biologically-derived plant oils for effectively transporting the blended fat based compositions over long distances, thereby advantageously decreasing the heating and mixing requirements needed to maintain the compositional temperature above the pour point. In certain embodiments, the fat based composition comprises rendered animal fats, such as tallow in combination with distilled corn oil (DCO).

The present invention provides improved processes for extracting and preparing lipids from biological sources for use in pharmaceuticals, nutraceuticals and functional foods.

A method for producing a high viscosity, low volatiles blown stripped oil blend is provided. The method may include the steps of: (i) obtaining an oil blend of corn stillage oil and soybean oil having a weight ratio of corn stillage oil to soybean oil of from about 1:2 to 3:1; (ii) heating the oil blend to at least 90° C.; (iii) passing air through the heated oil blend to produce a blown oil having a viscosity of at least 50 cSt at 40° C.; and (iv) stripping the blown oil from step (iii) to reduce an acid value of the blown oil to less than 5.0 mg KOH/gram.

Disclosed herein are host cells transformed with a nucleic acid molecule comprising a polynucleotide sequence, wherein the polynucleotide sequence encodes a polypeptide that hydrolyzes an ester linkage of a triacylglycerol in an oil comprising at least one long-chain polyunsaturated fatty acid, methods for using such host cells, and processes for production of a lipase using such host cells.

Process for refining vegetable oil, to suppress the formation of monochloropropanediol esters (MCPDe) and reduce the content of glycidyl esters, comprising first and second refinement stages, wherein the first refinement stage comprises: a) providing a crude vegetable oil having a combined MCPDe and glycidyl ester content below 0.2 ppm; b) degumming the crude vegetable oil to produced degummed vegetable oil; c) bleaching of the degummed vegetable oil with activated bleaching earth under reduced pressure to yield bleached vegetable oil; d) adding a base to the bleached vegetable oil and subsequent stripping and deodorizing under reduced pressure at a temperature below 255° C. to yield an intermediate refined vegetable oil; and a second refinement stage comprising the steps of: e) bleaching of the intermediate refined vegetable oil using activated bleaching earth under reduced pressure to yield a bleached vegetable oil; and f) deodorizing at a temperature below 220° C. to yield fully refined vegetable oil, wherein the fully refined vegetable oil has a combined MCPDe and glycidyl ester content below 4 ppm.
