Corn oil and corn meal obtained from corn are included in useful products. The corn oil is extracted from the corn to form the corn meal. The corn grain process generally includes the steps of cracking corn grain having a total oil content of from about 3 % by weight to about 30 % by weight and extracting a corn oil from the cracked corn grain. The corn oil is useful for making nutritionally enhanced edible oil or cooking oil, lubricants, biodiesel, fuel, cosmetics and oil-based or oil-containing chemical products. The extracted corn meal is useful for making enhanced animal feed rations, snack food, blended food products, cosmetics, and fermentation broth additive.

Corn oil processing and products comprising corn oil and corn meal obtained from corn

A continuous process for refining whole grain corn to obtain a prime corn starch fraction, an animal feed product and, optionally, corn oil. The process comprises dry milling corn kernels to provide an endosperm fraction, a germ fraction, a fiber (hull) fraction and a cleanings fraction, wet milling the endosperm fraction including using two distinct steeping steps, one upstream and the other downstream of an impact milling step, to provide a mill starch slurry. The process further comprises removing fine fiber tailings from the mill starch slurry, separating the slurry into a starch-rich fraction and protein-rich fraction, concentrating the protein-rich fraction, directly combining the fiber (hull), cleanings, fine fiber tailings and protein-rich concentrate without removing corn oil therefrom, with the germ fraction to provide a wet animal feed product, and drying the feed product. Optionally, corn oil is recovered from the germ fraction only.

Combined dry-wet milling process for refining corn

Corn oil and corn meal obtained from high oil corn are included in useful products. The corn oil is extracted from the high oil corn to form the corn meal. The corn oil generally comprises levels of nutrients not found in commercially available corn oils, since most or all of the corn grain, rather than just the germ, is exposed to the extraction process. The corn grain generally includes the steps of flaking corn grain having a total oil content of at least about 8 % and extracting a corn oil from the flaked corn grain. The corn oil is useful for making nutritionally enhanced edible oil or cooking oil, lubricants, biodiesel, fuel, cosmetics and oil-based or oil-containing chemical products. The extracted corn meal is useful for making enhanced animal feed rations, snack food, blended food products, cosmetics, and fermentation broth additive.

Products comprising corn oil and corn meal obtained from high oil corn

Corn oil is extracted from corn to form a corn meal. Processing the corn grain to obtain the oil, meal, and other product streams generally includes dividing the corn kernel by fractionating to create a higher oil fraction and a lower oil fraction, forming a solvent extractable structure from the higher oil fraction, and extracting the oil from the higher oil fraction. The extracted corn oil is useful for making nutritionally enhanced edible oil or cooking oil, lubricants, biodiesel, fuel, cosmetics and oil-based or oil-containing chemical products. The extracted corn meal is useful for making enhanced animal feed rations, snack food, blended food products, cosmetics, and fermentation broth additive. The lower oil fraction is useful for one or more processes such as fermentation, wet-milling, animal feed production, sweetener production, and starch production, making enhanced animal feed rations, snack food, blended food products, and cosmetics.

Process for increasing throughput of corn for oil extraction

An improved method for processing corn into ethanol and other valuable co-products. The invention generally involves a multi-step process which produces germ (or oil), protein, and feed yeast as its co-products while maintaining or enhancing the provision of fermentable sugar to ethanol fermentation. This is accomplished by fundamentally altering the way the corn is fractionated, disrupting the cell walls rather than the protein matrix as is done in conventional wet milling.

Corn fractionation method

A process for recovering starch and corn oil from corn kernels. The corn kernels are dry milled to separate the hulls and germ from the endosperm fractions. At least some of the endosperm fractions are steeped in separating the starch from the gluten. The gluten is dried and the separated germ and the dried corn gluten are subjected to solvent extraction to recover corn oil.
