The present invention refers to a process for reducing the amount of undesired components in an oil composition, particularly in an oil composition comprising omega-3 polyunsaturated fatty acids. The process of the present invention provides efficient removal of undesired water-soluble (hydrophilic) components and undesired fat-soluble (lipophilic) components from an oil composition in order to obtain a purified concentrate, e.g. a highly purified concentrate enriched in omega-3 polyunsaturated fatty acids.

Methods for producing oil from distillers corn oil having high free fatty acid content are provided. In the method, distiller's corn oil is treated with a mixture including an alcohol to result in a low-free fatty acid oily phase and an alcohol phase. The mixture may also include an alkali. The alcohol may be a monohydric alcohol and an aqueous alcohol, such as an aqueous alcohol having a concentration of at least about 15% alcohol-by-weight. The low-free fatty acid phase may include oil and at least one impurity. The low-free fatty acid phase may be cooled, and the oil may be separated from the at least one impurity using membrane filtration.

A method of applying energy to CBD oil is provided. The method may include obtaining CBD oil from a plant, combining the CBD oil with a carrier oil, heating the combination of the CBD oil and carrier oil, mixing the CBD oil and carrier oil, filtering the CBD oil and carrier oil to a size of less than 60 nanometers, and applying an energy field to the CBD oil and carrier oil through a laser effector such that an electron is promoted from a bonding or non-bonding orbital into an empty anti-bonding orbitals of the CBD molecule. The laser effector may be a pink sapphire cut into a 15 equal side faceted crystal, double-stacked in a 2.3 cm cylindrical chamber, or an opulence half dome bubble lens configured to refract the beam.

The present invention relates to a polypeptide having phospholipase C activity, selected from the group consisting of i. a polypeptide comprising a mature polypeptide sequence of SEQ ID NO: 2; ii. a polypeptide that has least 85%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98% or 99% identity to the mature polypeptide sequence of SEQ ID NO: 2; iii. a polypeptide encoded by a nucleic acid that hybridizes under medium stringency, preferably under high stringency conditions to the complementary strand of the mature polypeptide coding sequence of SEQ ID NO:1; iv. a polypeptide encoded by a nucleic acid that has at least 85%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or 100% identity to the mature polypeptide coding sequence of SEQ ID NO: 1.
