Abstract

A method of pressing sesame seeds to provide sesame flour having an oil content not greater than 45% by weight and sesame oil having a substantially 100% purity, and the sesame flour made by the method, and the sesame oil made by the method. The method comprises feeding dehulled sesame seeds into an expeller press having a choke opening for expelling sesame flour having an oil content not greater than 45% by weight in a single pressing, and maintaining a temperature not greater than 180° F. in the sesame food material being pressed, and extracting sesame oil at a rate of at least two-thirds by weight of the flour from the dehulled sesame seeds during the single pressing.

Claims

1. A method of pressing seeds to produce oil and flour comprising:

feeding dehulled sesame seeds free of calcium oxalate, oxalic acid, chemical, excretory and other contaminants into a screw press having a choke opening, while maintaining a temperature not greater than 180°

F. in the sesame food material being pressed, such that the press expels sesame flour having an oil content not greater than 45% by weight of oil in the flour in a single pressing of the seeds by the press, whereby sesame oil is extracted at a substantial rate with respect to the total yield of oil and flour extracted from the dehulled sesame seeds during the single pressing.

2. A method in accordance with claim 1, which includes the step of pre-heating the seeds to approximately 160°

F.

3. A method in accordance with claim 1, in which the step of maintaining the temperature of the food material being pressed comprises maintaining the temperature at approximately 175°

F.

4. A method in accordance with claim 1, in which the rate of feeding the seeds is approximately 350 pounds per hour.

5. A method in accordance with claim 1, in which the sesame seed is dried, the water moisture content being less than 3% in the flour.
