Abstract
Abstract A process for the extraction of oil from oats is disclosed. The process comprises extracting oil from comminuted oats with 2-propanol and separating the resultant 2-propanol solution from the de-oiled oats. Oat oil is recoverable from the 2-propanol solution. The 2-propanol may be in the form of an azeotropic mixture of 2-propanol and water. In a preferred embodiment the 2-propanol contains a minor amount e.g. 0.1- 1.0%, of hydrogen peroxide. The process is capable of producing a clear, lightly colored oil from oats. The oil is believed useful as a vegetable oil.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
94 words
A process for the extraction of oil from comminuted dehulled oats comprising the steps of: a. extracting oil from said comminuted dehulled oats by treating said oats with 2-propanol, said 2-propanol containing a minor amount of from about 0.1 weight percent to about 1.0 weight percent of hydrogen peroxide, at a temperature of from about 10° C. to about 75° C. whereby oil in the oats in extracted by said 2-propanol, b. separating the resultant solution comprising 2-propanol and extracted oil from the thus deoiled oats, and c. separating the oil from the 2-propanol.
Claim 2
Dependent Claim
94 words
A process for the extraction of oil from comminuted dehulled oats comprising the steps of: a. extracting oil from said comminuted dehulled oats by treating said oats with 2-propanol, said 2-propanol containing a minor amount of from about 0.1 weight percent to about 1.0 weight percent of hydrogen peroxide, at a temperature of from about 10° C. to about 75° C. whereby oil in the oats in extracted by said 2-propanol, b. separating the resultant solution comprising 2-propanol and extracted oil from the thus deoiled oats, and c. separating the oil from the 2-propanol.
Claim 3
Dependent Claim
18 words
The process of claim 1 in which the 2-propanol contains less than 1% by weight of hydrogen peroxide.
Claim 4
Dependent Claim
26 words
The process of claim 1 in which the temperature of the 2-propanol during said extraction is in the range of from 10° C. to 40° C.
