Abstract
Abstract An enriched, hydrogenated peanut oil-based peanut butter stabilizer and a method of preparing said peanut butter stabilizer comprising the steps of: (a) randomly interesterifying (randomizing) a first mixture of from 0% to 70% hydrogenated peanut oil (hardstock) and from 30% to 100% unhydrogenated peanut oil, preferably 30% to 70% hydrogenated peanut oil and 30% to 70% unhydrogenated peanut oil; (b) fractionally crystallizing from said first mixture a second mixture of triglycerides having at least 10% fatty acids having from 20 to 24 carbon atoms; and (c) substantially completely hydrogenating said second mixture to form said enriched hydrogenated peanut oil-based peanut butter stabilizer.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
99 words
A method of preparing an enriched, hydrogenated peanut-oil based peanut butter stabilizer comprising the steps of: (a) randomly interesterifying (randomizing) a first mixture of from about 0% to about 70% hydrogenated peanut oil (hardstock) and from about 30% to about 100% unhydrogenated peanut oil; (b) fractionally crystallizing from the randomly interesterified first mixture a second mixture of triglycerides having at least 10% long chain fatty acids having from 20 to 24 carbon atoms; and (c) substantially completely hydrogenating said second mixture to an iodine value less than about 8 to form said enriched hydrogenated peanut oil-based peanut butter stabilizer.
Claim 2
Independent Claim
99 words
A method of preparing an enriched, hydrogenated peanut-oil based peanut butter stabilizer comprising the steps of: (a) randomly interesterifying (randomizing) a first mixture of from about 0% to about 70% hydrogenated peanut oil (hardstock) and from about 30% to about 100% unhydrogenated peanut oil; (b) fractionally crystallizing from the randomly interesterified first mixture a second mixture of triglycerides having at least 10% long chain fatty acids having from 20 to 24 carbon atoms; and (c) substantially completely hydrogenating said second mixture to an iodine value less than about 8 to form said enriched hydrogenated peanut oil-based peanut butter stabilizer.
Claim 3
Dependent Claim
29 words
The method of claim 1 wherein said first mixture contains from about 30% to about 70% hydrogenated peanut oil and from about 30% to about 70% unhydrogenated peanut oil.
Claim 4
Dependent Claim
38 words
The method of claim 1 wherein said first mixture contains from about 0% to about 30% hydrogenated peanut oil and from about 70% to about 100% unhydrogenated peanut oil, and wherein random interesterification of step (a) is directed.
Claim 5
Dependent Claim
24 words
The methods of claims 1, 2 or 3, wherein said enriched hydrogenated peanut oil-based stabilizer comprises at least 21/2% long chain fatty acid triglycerides.
Claim 6
Dependent Claim
26 words
The peanut butter stabilizer of claims 1, 2 or 3, wherein said enriched hydrogenated peanut oil-based stabilizer comprises at least 14% long chain fatty acid triglycerides.
Claim 7
Independent Claim
25 words
The method of claims 1, 2 or 3 wherein said hydrogenated peanut oil (hardstock) of step (a) has an iodine value of less than 8.
Claim 8
Independent Claim
33 words
The method of claims 1, 2 or 3 wherein said second mixture is fractionally crystallized from a solvent selected from the group consisting of hexane, acetone, methanol, ethanol, chloroform and similar organic solvents.
Claim 9
Independent Claim
17 words
The method of claims 1, 2 or 3 wherein said second mixture is fractionally crystallized from hexane.
Claim 10
Independent Claim
17 words
The method of claims 1, 2 or 3 wherein said second mixture is fractionally crystallized from acetone.
