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

Lipid compositions

Disclosed is a continuous process for separating or extracting proteins from a low grade mixture of a protein of interest, other proteins, impurities, and salts in a continuous simulated moving bed separation process. The invention provides for direct extraction of heme protein and plant protein from a crude mixture of such proteins, other proteins, impurities and salts using the chromatographic technique of simulated moving bed (SMB) continuous chromatography. The SMB process combines the steps of feed loading, adsorbent washing, product elution, adsorbent regeneration, and adsorbent equilibration. The novel strong anion exchange resin adsorbent is a quaternary amine cross-linked microcellulose wherein the microcellulose is cross-linked with epichlorohydrin and the quaternary amine is 2,3-epoxypropyltrimethyl-ammonium chloride which exhibits selective adsorption of proteins and complete regeneration. Purified protein separated in this manner may provide human health benefits by providing greater medicinal and nutrition opportunities from low quality protein sources.

Continuous process for separation of proteins

Disclosed is a process for the separation and purification of a diacid from a fermentation broth withdrawn directly from a fermentation zone for producing the diacid, wherein the fermentation broth comprises the diacid and water, a corresponding monoacid, and a corresponding &#x3c9;-hydroxyacid. The process comprises passing the fermentation broth to a filtration zone having a filtration media and filtering the fermentation broth to provide a filtered feedstock. The filtered feedstock and a desorbent stream are passed to a simulated moving bed separation zone (SMB) operating in reverse phase at effective SMB conditions. The diacid may be adipic, acid, a 6-carbon atom diacid, or dodecanedioic acid, a 12-carbon atom diacid. The process is useful in simplifying the manufacturing the manufacture of diacids produced by fermentation. Adipic acid is used as monomer for the production of nylon. Dodecanedioic acid is used in antiseptics, coatings, painting materials, corrosion inhibitors, surfactants, and engineering plastics.
